Foreign exchange market                                                                                                       1

    Foreign exchange market
    The foreign exchange market (forex, FX, or currency market) is a form of exchange for the global decentralized
    trading of international currencies. Financial centers around the world function as anchors of trading between a wide
    range of different types of buyers and sellers around the clock, with the exception of weekends. EBS and Reuters'
    dealing 3000 are two main interbank FX trading platforms. The foreign exchange market determines the relative
    values of different currencies.[1]
    The foreign exchange market assists international trade and investment by enabling currency conversion. For
    example, it permits a business in the United States to import goods from the European Union member states
    especially Eurozone members and pay Euros, even though its income is in United States dollars. It also supports
    direct speculation in the value of currencies, and the carry trade, speculation based on the interest rate differential
    between two currencies.[2]
    In a typical foreign exchange transaction, a party purchases some quantity of one currency by paying some quantity
    of another currency. The modern foreign exchange market began forming during the 1970s after three decades of
    government restrictions on foreign exchange transactions (the Bretton Woods system of monetary management
    established the rules for commercial and financial relations among the world's major industrial states after World
    War II), when countries gradually switched to floating exchange rates from the previous exchange rate regime,
    which remained fixed as per the Bretton Woods system.
    The foreign exchange market is unique because of the following characteristics:
    • its huge trading volume representing the largest asset class in the world leading to high liquidity;
    • its geographical dispersion;
    • its continuous operation: 24 hours a day except weekends, i.e., trading from 20:15 GMT on Sunday until 22:00
      GMT Friday;
    • the variety of factors that affect exchange rates;
    • the low margins of relative profit compared with other markets of fixed income; and
    • the use of leverage to enhance profit and loss margins and with respect to account size.
    As such, it has been referred to as the market closest to the ideal of perfect competition, notwithstanding currency
    intervention by central banks. According to the Bank for International Settlements,[3] as of April 2010, average daily
    turnover in global foreign exchange markets is estimated at $3.98 trillion, a growth of approximately 20% over the
    $3.21 trillion daily volume as of April 2007. Some firms specializing on foreign exchange market had put the
    average daily turnover in excess of US$4 trillion.[4]
    The $3.98 trillion break-down is as follows:
    •   $1.490 trillion in spot transactions
    •   $475 billion in outright forwards
    •   $1.765 trillion in foreign exchange swaps
    •   $43 billion currency swaps
    •   $207 billion in options and other products

    Forex first occurred in ancient times.[5] Money-changing people, people helping others to change money and also
    taking a commission or charging a fee were living in the times of the Talmudic writings (Biblical times). These
    people (sometimes called "kollybistẻs") used city-stalls, at feast times the temples Court of the Gentiles instead.[6]
    The money-changer was also in more recent ancient times silver-smiths and, or, gold-smiths.[7]
    During the fourth century the Byzantium government kept a monopoly on forexes.[8]

    Medieval and later
    During the fifteenth century the Medici family were required to open banks at foreign locations in order to exchange
    currencies to act for textile merchants.[9][10] To facilitate trade the bank created the nostro (from Italian translated -
    "ours") account book which contained two columned entries showing amounts of foreign and local currencies,
    information pertaining to the keeping of an account with a foreign bank.[11][12][13][14] During the 17th (or 18th )
    century Amsterdam maintained an active forex market.[15] During 1704 foreign exchange took place between agents
    acting in the interests of the nations of England and Holland.[16]

    Early modern
    The firm Alexander Brown & Sons traded foreign currencies exchange sometime about 1850 and were a leading
    participant in this within the U.S. of A.[17] During 1880 J.M. do Espírito Santo de Silva (Banco Espírito e Comercial
    de Lisboa) applied for and was given permission to begin to engage in a foreign exchange trading business.[18][19]
    1880 is considered by one source to be the beginning of modern foreign exchange, significant for the fact of the
    beginning of the gold standard during the year.[20]
    Prior to the first world war there was a much more limited control of international trade. Motivated by the outset of
    war countries abandoned the gold standard monetary system.[21]

    Modern to post-modern

    Before WWII
    From 1899 to 1913 holdings of countries foreign exchange increased by 10.8%, while holdings of gold increased by
    At the time of the closing of the year 1913, nearly half of the world's forexes were being performed using sterling.[23]
    The number of foreign banks operating within the boundaries of London increased in the years from 1860 to 1913
    from 3 to 71. In 1902 there were altogether two London foreign exchange brokers.[24] In the earliest years of the
    twentieth century trade was most active in Paris, New York and Berlin, while Britain remained largely uninvolved in
    trade until 1914. Between 1919 and 1922 the employment of a foreign exchange brokers within London increased to
    17, in 1924 there were 40 firms operating for the purposes of exchange.[25] During the 1920s the occurrence of trade
    in London resembled more the modern manifestation, by 1928 forex trade was integral to the financial functioning of
    the city. Continental exchange controls, plus other factors, in Europe and Latin America, hampered any attempt at
    wholesale prosperity from trade for those of 1930's London.[26]
    During the 1920s foreign exchange the Kleinwort family were known to be the leaders of the market, Japhets,
    S,Montagu & Co. and Seligmans as significant participants still warrant recognition.[27] In the year 1945 the nation
    of Ethiopias' government possessed a foreign exchange surplus.[28]

    After WWII
    After WWII the Bretton Woods Accord was signed allowing currencies to fluctuate within a range of 1% to the
    currencies par.[29] In Japan the law was changed during 1954 by the Foreign Exchange Bank Law, so, the Bank of
    Tokyo was to become because of this the centre of foreign exchange by September of that year. Between 1954 and
    1959 Japanese law was made to allow the inclusion of many more Occidental currencies in Japanese forex.[30]
    President Nixon is credited with ending the Bretton Woods Accord, and fixed rates of exchange, bringing about
    eventually a free-floating currency system. After the ceasing of the enactment of the Bretton Woods Accord (during
    1971 [31]) the Smithsonian agreement allowed trading to range to 2%. During 1961-62 the amount of foreign
    operations by the U.S. of America's Federal Reserve was relatively low.[32][33] Those involved in controlling
    exchange rates found the boundaries of the Agreement were not realistic and so ceased this in March 1973, when
    sometime afterward none of the major currencies were maintained with a capacity for conversion to gold,
    organisations relied instead on reserves of currency.[34][35] During 1970 to 1973 the amount of trades occurring in
    the market increased three-fold.[36][37][38] At some time (according to Gandolfo during February–March 1973) some
    of the markets' were "split", so a two tier currency market was subsequently introduced, with dual currency rates.
    This was abolished during March 1974.[39][40][41]
    Reuters introduced during June 1973 computer monitors, replacing the telephones and telex used previously for
    trading quotes.[42]

    -markets close
    Due to the ultimate ineffectiveness of the Bretton Woods Accord and the European Joint Float the forex markets
    were forced to close sometime during 1972 and March 1973.[43][44] The very largest of all purchases of dollars in the
    history of 1976 was when the West German government achieved an almost 3 billion dollar acquisition (a figure
    given as 2.75 billion in total by The Statesman: Volume 18 1974 → [45]), this event indicated the impossibility of
    the balancing of exchange stabilities by the measures of control used at the time and the monetary system and the
    foreign exchange markets in "West" Germany and other countries within Europe closed for two weeks (during
    February and, or, March 1973. Giersch, Paqué, & Schmieding state closed after purchase of "7.5 million Dmarks"
    Brawley states "... Exchange markets had to be closed. When they re-opened ... March 1 " that is a large purchase
    occurred after the close).[46][47][48][49]

    after 1973
    In fact 1973 marks the point to which nation-state, banking trade and controlled foreign exchange ended and
    complete floating, relatively free conditions of a market characteristic of the situation in contemporary times began
    (according to one source),[50] although another states the first time a currency pair were given as an option for U.S.A.
    traders to purchase was during 1982, with additional currencies available by the next year.[51][52]
    On 1 January 1981 (as part of changes beginning during 1978 [53]) the Bank of China allowed certain domestic
    "enterprises" to participate in foreign exchange trading.[54] Sometime during the months of 1981 the South Korean
    government ended forex controls and allowed free trade to occur for the first time. During 1988 the countries
    government accepted the IMF quota for international trade.[55]
    Intervention by European banks especially the Bundesbank influenced the forex market, on February the 27th 1985
    particularly.[56] The greatest proportion of all trades world-wide during 1987 were within the United Kingdom,
    slightly over one quarter, with the U.S. of America the nation with the second most places involved in trading.[57]
    During 1991 the republic of Iran changed international agreements with some countries from oil-barter to foreign

    Market size and liquidity
    The foreign exchange market is the most
    liquid financial market in the world. Traders
    include large banks, central banks,
    institutional investors, currency speculators,
    corporations, governments, other financial
    institutions, and retail investors. The
    average daily turnover in the global foreign
    exchange       and    related     markets   is
    continuously growing. According to the
    2010 Triennial Central Bank Survey,
    coordinated by the Bank for International
    Settlements, average daily turnover was
    US$3.98 trillion in April 2010 (vs $1.7
    trillion in 1998).[3] Of this $3.98 trillion,     Main foreign exchange market turnover, 1988–2007, measured in billions of USD.

    $1.5 trillion was spot transactions and $2.5
    trillion was traded in outright forwards, swaps and other derivatives.

    Trading in the United Kingdom accounted for 36.7% of the total, making it by far the most important centre for
    foreign exchange trading. Trading in the United States accounted for 17.9%, and Japan accounted for 6.2%.[59]
    Turnover of exchange-traded foreign exchange futures and options have grown rapidly in recent years, reaching
    $166 billion in April 2010 (double the turnover recorded in April 2007). Exchange-traded currency derivatives
    represent 4% of OTC foreign exchange turnover. Foreign exchange futures contracts were introduced in 1972 at the
    Chicago Mercantile Exchange and are actively traded relative to most other futures contracts.
    Most developed countries permit the trading of derivative products (like futures and options on futures) on their
    exchanges. All these developed countries already have fully convertible capital accounts. Some governments of
    emerging economies do not allow foreign exchange derivative products on their exchanges because they have capital
    controls. The use of derivatives is growing in many emerging economies.[60] Countries such as Korea, South Africa,
    and India have established currency futures exchanges, despite having some capital controls.

    Foreign exchange trading increased by 20% between April 2007 and April 2010 and has more than doubled since
    2004.[62] The increase in turnover is due to a number of factors: the growing importance of foreign exchange as an
    asset class, the increased trading activity of high-frequency traders, and the emergence of retail investors as an
    important market segment. The growth of electronic execution and the diverse selection of execution venues has
    lowered transaction costs, increased market liquidity, and attracted greater participation from many customer types.
    In particular, electronic trading via online portals has made it easier for retail traders to trade in the foreign exchange
    market. By 2010, retail trading is estimated to account for up to 10% of spot turnover, or $150 billion per day (see
    retail foreign exchange platform).
    Foreign exchange is an over-the-counter market where brokers/dealers negotiate directly with one another, so there is
    no central exchange or clearing house. The biggest geographic trading center is the United Kingdom, primarily
    London, which according to TheCityUK estimates has increased its share of global turnover in traditional
    transactions from 34.6% in April 2007 to 36.7% in April 2010. Due to London's dominance in the market, a
    particular currency's quoted price is usually the London market price. For instance, when the International Monetary
    Fund calculates the value of its special drawing rights every day, they use the London market prices at noon that day.

    Market participants
    Unlike a stock market, the foreign exchange market is divided into levels of access. At the top is the interbank
    market, which is made up of the largest commercial banks and securities dealers. Within the interbank market,
    spreads, which are the difference between the bid and ask prices, are razor sharp and not known to players outside
    the inner circle. The difference between the bid and ask prices widens (for example from 0-1 pip to 1-2 pips for a
    currencies such as the EUR) as you go down the levels of access. This is due to volume. If a trader can guarantee
    large numbers of transactions for large amounts, they can demand a smaller difference between the bid and ask price,
    which is referred to as a better spread. The levels of access that make up the foreign exchange market are determined
    by the size of the "line" (the amount of money with which they are trading). The top-tier interbank market accounts
    for 39% of all transactions.[59] From there, smaller banks, followed by large multi-national corporations (which need
    to hedge risk and pay employees in different countries), large hedge funds, and even some of the retail market
    makers. According to Galati and Melvin, “Pension funds, insurance companies, mutual funds, and other institutional
    investors have played an increasingly important role in financial markets in general, and in FX markets in particular,
    since the early 2000s.” (2004) In addition, he notes, “Hedge funds have grown markedly over the 2001–2004 period
    in terms of both number and overall size”.[63] Central banks also participate in the foreign exchange market to align
    currencies to their economic needs.

    Commercial companies
    An important part of this market comes from the financial activities of companies seeking foreign exchange to pay
    for goods or services. Commercial companies often trade fairly small amounts compared to those of banks or
    speculators, and their trades often have little short term impact on market rates. Nevertheless, trade flows are an
    important factor in the long-term direction of a currency's exchange rate. Some multinational companies can have an
    unpredictable impact when very large positions are covered due to exposures that are not widely known by other
    market participants.

    Central banks
    National central banks play an important role in the foreign exchange markets. They try to control the money supply,
    inflation, and/or interest rates and often have official or unofficial target rates for their currencies. They can use their
    often substantial foreign exchange reserves to stabilize the market. Nevertheless, the effectiveness of central bank
    "stabilizing speculation" is doubtful because central banks do not go bankrupt if they make large losses, like other
    traders would, and there is no convincing evidence that they do make a profit trading.

    Foreign exchange fixing
    Foreign exchange fixing is the daily monetary exchange rate fixed by the national bank of each country. The idea is
    that central banks use the fixing time and exchange rate to evaluate behavior of their currency. Fixing exchange rates
    reflects the real value of equilibrium in the market. Banks, dealers and traders use fixing rates as a trend indicator.
    The mere expectation or rumor of a central bank foreign exchange intervention might be enough to stabilize a
    currency, but aggressive intervention might be used several times each year in countries with a dirty float currency
    regime. Central banks do not always achieve their objectives. The combined resources of the market can easily
    overwhelm any central bank.[64] Several scenarios of this nature were seen in the 1992–93 European Exchange Rate
    Mechanism collapse, and in more recent times in Asia.

    Hedge funds as speculators
    About 70% to 90% of the foreign exchange transactions are speculative. In other words, the person or institution that
    bought or sold the currency has no plan to actually take delivery of the currency in the end; rather, they were solely
    speculating on the movement of that particular currency. Hedge funds have gained a reputation for aggressive
    currency speculation since 1996. They control billions of dollars of equity and may borrow billions more, and thus
    may overwhelm intervention by central banks to support almost any currency, if the economic fundamentals are in
    the hedge funds' favor.

    Investment management firms
    Investment management firms (who typically manage large accounts on behalf of customers such as pension funds
    and endowments) use the foreign exchange market to facilitate transactions in foreign securities. For example, an
    investment manager bearing an international equity portfolio needs to purchase and sell several pairs of foreign
    currencies to pay for foreign securities purchases.
    Some investment management firms also have more speculative specialist currency overlay operations, which
    manage clients' currency exposures with the aim of generating profits as well as limiting risk. While the number of
    this type of specialist firms is quite small, many have a large value of assets under management) and, hence, can
    generate large trades.

    Retail foreign exchange traders
    Individual Retail speculative traders constitute a growing segment of this market with the advent of retail foreign
    exchange platforms, both in size and importance. Currently, they participate indirectly through brokers or banks.
    Retail brokers, while largely controlled and regulated in the USA by the Commodity Futures Trading Commission
    and National Futures Association have in the past been subjected to periodic Foreign exchange fraud.[65][66] To deal
    with the issue, in 2010 the NFA required its members that deal in the Forex markets to register as such (I.e., Forex
    CTA instead of a CTA). Those NFA members that would traditionally be subject to minimum net capital
    requirements, FCMs and IBs, are subject to greater minimum net capital requirements if they deal in Forex. A
    number of the foreign exchange brokers operate from the UK under Financial Services Authority regulations where
    foreign exchange trading using margin is part of the wider over-the-counter derivatives trading industry that includes
    Contract for differences and financial spread betting.
    There are two main types of retail FX brokers offering the opportunity for speculative currency trading: brokers and
    dealers or market makers. Brokers serve as an agent of the customer in the broader FX market, by seeking the best
    price in the market for a retail order and dealing on behalf of the retail customer. They charge a commission or
    mark-up in addition to the price obtained in the market. Dealers or market makers, by contrast, typically act as
    principal in the transaction versus the retail customer, and quote a price they are willing to deal at.

    Non-bank foreign exchange companies
    Non-bank foreign exchange companies offer currency exchange and international payments to private individuals
    and companies. These are also known as foreign exchange brokers but are distinct in that they do not offer
    speculative trading but rather currency exchange with payments (i.e., there is usually a physical delivery of currency
    to a bank account).
    It is estimated that in the UK, 14% of currency transfers/payments[67] are made via Foreign Exchange
    Companies.[68] These companies' selling point is usually that they will offer better exchange rates or cheaper
    payments than the customer's bank. These companies differ from Money Transfer/Remittance Companies in that
    they generally offer higher-value services.

    Money transfer/remittance companies and bureaux de change
    Money transfer companies/remittance companies perform high-volume low-value transfers generally by economic
    migrants back to their home country. In 2007, the Aite Group estimated that there were $369 billion of remittances
    (an increase of 8% on the previous year). The four largest markets (India, China, Mexico and the Philippines) receive

    There is no unified or centrally cleared market for the majority of trades, and there is very little cross-border
    regulation. Due to the over-the-counter (OTC) nature of currency markets, there are rather a number of
    interconnected marketplaces, where different currencies instruments are traded. This implies that there is not a single
    exchange rate but rather a number of different rates (prices), depending on what bank or market maker is trading, and
    where it is. In practice the rates are quite close due to arbitrage. Due to London's dominance in the market, a
    particular currency's quoted price is usually the London market price. Major trading exchanges include EBS and
    Reuters, while major banks also offer trading systems. A joint venture of the Chicago Mercantile Exchange and
    Reuters, called Fxmarketspace opened in 2007 and aspired but failed to the role of a central market clearing
    The main trading centers are New York and London, though Tokyo, Hong Kong and Singapore are all important
    centers as well. Banks throughout the world participate. Currency trading happens continuously throughout the day;
    as the Asian trading session ends, the European session begins, followed by the North American session and then
    back to the Asian session, excluding weekends.
    Fluctuations in exchange rates are usually caused by actual monetary flows as well as by expectations of changes in
    monetary flows caused by changes in gross domestic product (GDP) growth, inflation (purchasing power parity
    theory), interest rates (interest rate parity, Domestic Fisher effect, International Fisher effect), budget and trade
    deficits or surpluses, large cross-border M&A deals and other macroeconomic conditions. Major news is released
    publicly, often on scheduled dates, so many people have access to the same news at the same time. However, the
    large banks have an important advantage; they can see their customers' order flow.
    Currencies are traded against one another in pairs. Each currency pair thus constitutes an individual trading product
    and is traditionally noted XXXYYY or XXX/YYY, where XXX and YYY are the ISO 4217 international three-letter
    code of the currencies involved. The first currency (XXX) is the base currency that is quoted relative to the second
    currency (YYY), called the counter currency (or quote currency). For instance, the quotation EURUSD (EUR/USD)
    1.5465 is the price of the euro expressed in US dollars, meaning 1 euro = 1.5465 dollars. The market convention is to
    quote most exchange rates against the USD with the US dollar as the base currency (e.g. USDJPY, USDCAD,
    USDCHF). The exceptions are the British pound (GBP), Australian dollar (AUD), the New Zealand dollar (NZD)
    and the euro (EUR) where the USD is the counter currency (e.g. GBPUSD, AUDUSD, NZDUSD, EURUSD).
    The factors affecting XXX will affect both XXXYYY and XXXZZZ. This causes positive currency correlation
    between XXXYYY and XXXZZZ.
    On the spot market, according to the 2010 Triennial Survey, the most heavily traded bilateral currency pairs were:
    • EURUSD: 28%
    • USDJPY: 14%
    • GBPUSD (also called cable): 9%
    and the US currency was involved in 84.9% of transactions, followed by the euro (39.1%), the yen (19.0%), and
    sterling (12.9%) (see table). Volume percentages for all individual currencies should add up to 200%, as each
    transaction involves two currencies.
    Trading in the euro has grown considerably since the currency's creation in January 1999, and how long the foreign
    exchange market will remain dollar-centered is open to debate. Until recently, trading the euro versus a
    non-European currency ZZZ would have usually involved two trades: EURUSD and USDZZZ. The exception to this
    is EURJPY, which is an established traded currency pair in the interbank spot market. As the dollar's value has
    eroded during 2008, interest in using the euro as reference currency for prices in commodities (such as oil), as well
    as a larger component of foreign reserves by banks, has increased dramatically. Transactions in the currencies of

    Determinants of exchange rates
    The following theories explain the fluctuations in exchange rates in a floating exchange rate regime (In a fixed
    exchange rate regime, rates are decided by its government):
    1. International parity conditions: Relative Purchasing Power Parity, interest rate parity, Domestic Fisher effect,
       International Fisher effect. Though to some extent the above theories provide logical explanation for the
       fluctuations in exchange rates, yet these theories falter as they are based on challengeable assumptions [e.g., free
       flow of goods, services and capital] which seldom hold true in the real world.
    2. Balance of payments model (see exchange rate): This model, however, focuses largely on tradable goods and
       services, ignoring the increasing role of global capital flows. It failed to provide any explanation for continuous
       appreciation of dollar during 1980s and most part of 1990s in face of soaring US current account deficit.
    3. Asset market model (see exchange rate): views currencies as an important asset class for constructing investment
       portfolios. Assets prices are influenced mostly by people's willingness to hold the existing quantities of assets,
       which in turn depends on their expectations on the future worth of these assets. The asset market model of
       exchange rate determination states that “the exchange rate between two currencies represents the price that just
       balances the relative supplies of, and demand for, assets denominated in those currencies.”
    None of the models developed so far succeed to explain exchange rates and volatility in the longer time frames. For
    shorter time frames (less than a few days) algorithms can be devised to predict prices. It is understood from the
    above models that many macroeconomic factors affect the exchange rates and in the end currency prices are a result
    of dual forces of demand and supply. The world's currency markets can be viewed as a huge melting pot: in a large
    and ever-changing mix of current events, supply and demand factors are constantly shifting, and the price of one
    currency in relation to another shifts accordingly. No other market encompasses (and distills) as much of what is
    going on in the world at any given time as foreign exchange.[70]
    Supply and demand for any given currency, and thus its value, are not influenced by any single element, but rather
    by several. These elements generally fall into three categories: economic factors, political conditions and market

    Economic factors
    These include: (a) economic policy, disseminated by government agencies and central banks, (b) economic
    conditions, generally revealed through economic reports, and other economic indicators.
    • Economic policy comprises government fiscal policy (budget/spending practices) and monetary policy (the means
      by which a government's central bank influences the supply and "cost" of money, which is reflected by the level
      of interest rates).
    • Government budget deficits or surpluses: The market usually reacts negatively to widening government budget
      deficits, and positively to narrowing budget deficits. The impact is reflected in the value of a country's currency.
    • Balance of trade levels and trends: The trade flow between countries illustrates the demand for goods and
      services, which in turn indicates demand for a country's currency to conduct trade. Surpluses and deficits in trade
      of goods and services reflect the competitiveness of a nation's economy. For example, trade deficits may have a
      negative impact on a nation's currency.
    • Inflation levels and trends: Typically a currency will lose value if there is a high level of inflation in the country
      or if inflation levels are perceived to be rising. This is because inflation erodes purchasing power, thus demand,
      for that particular currency. However, a currency may sometimes strengthen when inflation rises because of
      expectations that the central bank will raise short-term interest rates to combat rising inflation.
    • Economic growth and health: Reports such as GDP, employment levels, retail sales, capacity utilization and
      others, detail the levels of a country's economic growth and health. Generally, the more healthy and robust a

      country's economy, the better its currency will perform, and the more demand for it there will be.
    • Productivity of an economy: Increasing productivity in an economy should positively influence the value of its
      currency. Its effects are more prominent if the increase is in the traded sector [71].

    Political conditions
    Internal, regional, and international political conditions and events can have a profound effect on currency markets.
    All exchange rates are susceptible to political instability and anticipations about the new ruling party. Political
    upheaval and instability can have a negative impact on a nation's economy. For example, destabilization of coalition
    governments in Pakistan and Thailand can negatively affect the value of their currencies. Similarly, in a country
    experiencing financial difficulties, the rise of a political faction that is perceived to be fiscally responsible can have
    the opposite effect. Also, events in one country in a region may spur positive/negative interest in a neighboring
    country and, in the process, affect its currency.

    Market psychology
    Market psychology and trader perceptions influence the foreign exchange market in a variety of ways:
    • Flights to quality: Unsettling international events can lead to a "flight to quality", a type of capital flight whereby
      investors move their assets to a perceived "safe haven". There will be a greater demand, thus a higher price, for
      currencies perceived as stronger over their relatively weaker counterparts. The U.S. dollar, Swiss franc and gold
      have been traditional safe havens during times of political or economic uncertainty.[72]
    • Long-term trends: Currency markets often move in visible long-term trends. Although currencies do not have an
      annual growing season like physical commodities, business cycles do make themselves felt. Cycle analysis looks
      at longer-term price trends that may rise from economic or political trends.[73]
    • "Buy the rumor, sell the fact": This market truism can apply to many currency situations. It is the tendency for the
      price of a currency to reflect the impact of a particular action before it occurs and, when the anticipated event
      comes to pass, react in exactly the opposite direction. This may also be referred to as a market being "oversold" or
      "overbought".[74] To buy the rumor or sell the fact can also be an example of the cognitive bias known as
      anchoring, when investors focus too much on the relevance of outside events to currency prices.
    • Economic numbers: While economic numbers can certainly reflect economic policy, some reports and numbers
      take on a talisman-like effect: the number itself becomes important to market psychology and may have an
      immediate impact on short-term market moves. "What to watch" can change over time. In recent years, for
      example, money supply, employment, trade balance figures and inflation numbers have all taken turns in the
    • Technical trading considerations: As in other markets, the accumulated price movements in a currency pair such
      as EUR/USD can form apparent patterns that traders may attempt to use. Many traders study price charts in order
      to identify such patterns.[75]

    Financial instruments

    A spot transaction is a two-day delivery transaction (except in the case of trades between the US Dollar, Canadian
    Dollar, Turkish Lira, Euro and Russian Ruble, which settle the next business day), as opposed to the futures
    contracts, which are usually three months. This trade represents a “direct exchange” between two currencies, has the
    shortest time frame, involves cash rather than a contract; and interest is not included in the agreed-upon transaction.

    One way to deal with the foreign exchange risk is to engage in a forward transaction. In this transaction, money does
    not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any
    date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration
    of the trade can be one day, a few days, months or years. Usually the date is decided by both parties. Then the
    forward contract is negotiated and agreed upon by both parties.

    The most common type of forward transaction is the swap. In a swap, two parties exchange currencies for a certain
    length of time and agree to reverse the transaction at a later date. These are not standardized contracts and are not
    traded through an exchange. A deposit is often required in order to hold the position open until the transaction is

    Futures are standardized forward contracts and are usually traded on an exchange created for this purpose. The
    average contract length is roughly 3 months. Futures contracts are usually inclusive of any interest amounts.

    A foreign exchange option (commonly shortened to just FX option) is a derivative where the owner has the right but
    not the obligation to exchange money denominated in one currency into another currency at a pre-agreed exchange
    rate on a specified date. The options market is the deepest, largest and most liquid market for options of any kind in
    the world.

    Controversy about currency speculators and their effect on currency devaluations and national economies recurs
    regularly. Nevertheless, economists including Milton Friedman have argued that speculators ultimately are a
    stabilizing influence on the market and perform the important function of providing a market for hedgers and
    transferring risk from those people who don't wish to bear it, to those who do.[76] Other economists such as Joseph
    Stiglitz consider this argument to be based more on politics and a free market philosophy than on economics.[77]
    Large hedge funds and other well capitalized "position traders" are the main professional speculators. According to
    some economists, individual traders could act as "noise traders" and have a more destabilizing role than larger and
    better informed actors.[78]
    Currency speculation is considered a highly suspect activity in many countries. While investment in traditional
    financial instruments like bonds or stocks often is considered to contribute positively to economic growth by
    providing capital, currency speculation does not; according to this view, it is simply gambling that often interferes
    with economic policy. For example, in 1992, currency speculation forced the Central Bank of Sweden to raise
    interest rates for a few days to 500% per annum, and later to devalue the krona.[79] Former Malaysian Prime Minister
Foreign exchange market                                                                                                        12

    Mahathir Mohamad is one well known proponent of this view. He blamed the devaluation of the Malaysian ringgit in
    1997 on George Soros and other speculators.
    Gregory J. Millman reports on an opposing view, comparing speculators to "vigilantes" who simply help "enforce"
    international agreements and anticipate the effects of basic economic "laws" in order to profit.[80]
    In this view, countries may develop unsustainable financial bubbles or otherwise mishandle their national
    economies, and foreign exchange speculators made the inevitable collapse happen sooner. A relatively quick
    collapse might even be preferable to continued economic mishandling, followed by an eventual, larger, collapse.
    Mahathir Mohamad and other critics of speculation are viewed as trying to deflect the blame from themselves for
    having caused the unsustainable economic conditions.

    Risk aversion
    Risk aversion is a kind of trading behavior exhibited by the foreign
    exchange market when a potentially adverse event happens which may
    affect market conditions. This behavior is caused when risk averse
    traders liquidate their positions in risky assets and shift the funds to
    less risky assets due to uncertainty.[81]
    In the context of the foreign exchange market, traders liquidate their
    positions in various currencies to take up positions in safe-haven          Fig.1 Chart showing MSCI World Index of
                                       [82]                                    Equities fell while the US Dollar Index rose.
    currencies, such as the US Dollar.      Sometimes, the choice of a safe
    haven currency is more of a choice based on prevailing sentiments
    rather than one of economic statistics. An example would be the Financial Crisis of 2008. The value of equities
    across the world fell while the US Dollar strengthened (see Fig.1). This happened despite the strong focus of the
    crisis in the USA.[83]

    Carry Trade
    Currency carry trade refers to the act of borrowing one currency that has a low interest rate in order to purchase
    another with a higher interest rate. A large difference in rates can be highly profitable for the trader, especially if
    high leverage is used. However, with all levered investments this is a double edged sword, and large exchange rate
    fluctuations can suddenly swing trades into huge losses.

    Forex Signals
    Forex trade alerts, often referred to as Forex Signals are trade strategies provided by either experienced traders or
    market analysts. These signals which are often charged a premium fee for can then be copied or replicated by a
    trader to his own live account. Forex Signal products are packaged as either alerts delivered to a users inbox or sms,
    or can be installed to a trader's trading platform.

    Currency band
    The currency band is a system of exchange rates by which a floating currency is backed by hard money.
    A country selects a range, or "band", of values at which to set their currency, and returns to a fixed exchange rate if
    the value of their currency shifts outside this band. This allows for some revaluation, but tends to stabilize the
    currency's value within the band. In this sense, it is a compromise between a fixed (or "pegged") exchange rate and a
    floating exchange rate. For example, the exchange rate of the renminbi of the mainland of the People's Republic of
    China has recently been based upon a currency band; the European Economic Community's "snake in the tunnel"
    was a similar concept that failed, but ultimately led to the establishment of the European Exchange Rate Mechanism
    (ERM) and ultimately the Euro.
Exchange rate                                                                                                                 18

    Exchange rate
    In finance, an exchange rate (also known as the foreign-exchange rate, forex rate or FX rate) between two
    currencies is the rate at which one currency will be exchanged for another. It is also regarded as the value of one
    country’s currency in terms of another currency.[1] For example, an interbank exchange rate of 91 Japanese yen (JPY,
    ¥) to the United States dollar (US$) means that ¥91 will be exchanged for each US$1 or that US$1 will be exchanged
    for each ¥91. Exchange rates are determined in the foreign exchange market,[2] which is open to a wide range of
    different types of buyers and sellers where currency trading is continuous: 24 hours a day except weekends, i.e.
    trading from 20:15 GMT on Sunday until 22:00 GMT Friday. The spot exchange rate refers to the current exchange
    rate. The forward exchange rate refers to an exchange rate that is quoted and traded today but for delivery and
    payment on a specific future date.
    In the retail currency exchange market, a different buying rate and selling rate will be quoted by money dealers.
    Most trades are to or from the local currency. The buying rate is the rate at which money dealers will buy foreign
    currency, and the selling rate is the rate at which they will sell the currency. The quoted rates will incorporate an
    allowance for a dealer's margin (or profit) in trading, or else the margin may be recovered in the form of a
    "commission" or in some other way. Different rates may also be quoted for cash (usually notes only), a documentary
    form (such as traveller's cheques) or electronically (such as a credit card purchase). The higher rate on documentary
    transactions is due to the additional time and cost of clearing the document, while the cash is available for resale
    immediately. Some dealers on the other hand prefer documentary transactions because of the security concerns with

    Retail exchange market
    People may need to exchange currencies in a number of situations. For example, people intending to travel to
    another country may buy foreign currency in a bank in their home country, where they may buy foreign currency
    cash, traveller's cheques or a travel-card. From a local money changer they can only buy foreign cash. At the
    destination, the traveller can buy local currency at the airport, either from a dealer or through an ATM. They can also
    buy local currency at their hotel, a local money changer, through an ATM, or at a bank branch. When they purchase
    goods in a store and they do not have local currency, they can use a credit card, which will convert to the purchaser's
    home currency at its prevailing exchange rate. If they have traveller's cheques or a travel card in the local currency,
    no currency exchange is necessary. Then, if a traveller has any foreign currency left over on their return home, may
    want to sell it, which they may do at their local bank or money changer. The exchange rate as well as fees and
    charges can vary significantly on each of these transactions, and the exchange rate can vary from one day to the next.
    There are variations in the quoted buying and selling rates for a currency between foreign exchange dealers and
    forms of exchange, and these variations can be significant. For example, consumer exchange rates used by Visa and
    MasterCard offer the most favorable exchange rates available, according to a Currency Exchange Study conducted
    by[3] This studied consumer banks in the U.S., and Travelex, showed that the credit card networks
    save travellers about 8% relative to banks and roughly 15% relative to airport companies.[3]
Exchange rate                                                                                                                19

    A currency pair is the quotation of the relative value of a
    currency unit against the unit of another currency in the
    foreign exchange market. The quotation EUR/USD 1.2500
    means that 1 Euro is exchanged for 1.2500 US dollars.
    There is a market convention that determines which is the
    base currency and which is the term currency. In most parts
    of the world, the order is: EUR – GBP – AUD – NZD –
    USD – others. Accordingly, a conversion from EUR to
    AUD, EUR is the base currency, AUD is the term currency
    and the exchange rate indicates how many Australian dollars
    would be paid or received for 1 Euro. Cyprus and Malta
    which were quoted as the base to the USD and others were
    recently removed from this list when they joined the Euro.

    In some areas of Europe and in the non-professional market
    in the UK, EUR and GBP are reversed so that GBP is quoted
    as the base currency to the euro. In order to determine which
    is the base currency where both currencies are not listed (i.e.
    both are "other"), market convention is to use the base
    currency which gives an exchange rate greater than 1.000.
    This avoids rounding issues and exchange rates being quoted
    to more than 4 decimal places. There are some exceptions to
    this rule e.g. the Japanese often quote their currency as the
    base to other currencies.                                                    Exchange rates display in Thailand

    Quotes using a country's home currency as the price currency
    (e.g., EUR 0.735342 = USD 1.00 in the euro zone) are known as direct quotation or price quotation (from that
    country's perspective)[4] and are used by most countries.
    Quotes using a country's home currency as the unit currency (e.g., EUR 1.00 = USD 1.35991 in the euro zone) are
    known as indirect quotation or quantity quotation and are used in British newspapers and are also common in
    Australia, New Zealand and the eurozone.
    Using direct quotation, if the home currency is strengthening (i.e., appreciating, or becoming more valuable) then the
    exchange rate number decreases. Conversely if the foreign currency is strengthening, the exchange rate number
    increases and the home currency is depreciating.
    Market convention from the early 1980s to 2006 was that most currency pairs were quoted to 4 decimal places for
    spot transactions and up to 6 decimal places for forward outrights or swaps. (The fourth decimal place is usually
    referred to as a "pip"). An exception to this was exchange rates with a value of less than 1.000 which were usually
    quoted to 5 or 6 decimal places. Although there is no fixed rule, exchange rates with a value greater than around 20
    were usually quoted to 3 decimal places and currencies with a value greater than 80 were quoted to 2 decimal places.
    Currencies over 5000 were usually quoted with no decimal places (e.g. the former Turkish Lira). e.g. (GBPOMR :
    0.765432 - : 1.4436 - EURJPY : 165.29). In other words, quotes are given with 5 digits. Where rates are below 1,
    quotes frequently include 5 decimal places.
    In 2005 Barclays Capital broke with convention by offering spot exchange rates with 5 or 6 decimal places on their
    electronic dealing platform.[5] The contraction of spreads (the difference between the bid and offer rates) arguably
    necessitated finer pricing and gave the banks the ability to try and win transaction on multibank trading platforms
    where all banks may otherwise have been quoting the same price. A number of other banks have now followed this
Exchange rate                                                                                                                   20


    Exchange rate regime
    Each country, through varying mechanisms, manages the value of its currency. As part of this function, it determines
    the exchange rate regime that will apply to its currency. For example, the currency may be free-floating, pegged or
    fixed, or a hybrid.
    If a currency is free-floating, its exchange rate is allowed to vary against that of other currencies and is determined
    by the market forces of supply and demand. Exchange rates for such currencies are likely to change almost
    constantly as quoted on financial markets, mainly by banks, around the world.
    A movable or adjustable peg system is a system of fixed exchange rates, but with a provision for the devaluation of a
    currency. For example, between 1994 and 2005, the Chinese yuan renminbi (RMB) was pegged to the United States
    dollar at RMB 8.2768 to $1. China was not the only country to do this; from the end of World War II until 1967,
    Western European countries all maintained fixed exchange rates with the US dollar based on the Bretton Woods
    system. [6] But that system had to be abandoned due to market pressures and speculations in the 1970s in favor of
    floating, market-based regimes.
    Still, some governments keep their currency within a narrow range. As a result currencies become over-valued or
    under-valued, causing trade deficits or surpluses.

    Fluctuations in exchange rates
    A market-based exchange rate will change whenever the values of either of the two component currencies change. A
    currency will tend to become more valuable whenever demand for it is greater than the available supply. It will
    become less valuable whenever demand is less than available supply (this does not mean people no longer want
    money, it just means they prefer holding their wealth in some other form, possibly another currency).
    Increased demand for a currency can be due to either an increased transaction demand for money or an increased
    speculative demand for money. The transaction demand is highly correlated to a country's level of business activity,
    gross domestic product (GDP), and employment levels. The more people that are unemployed, the less the public as
    a whole will spend on goods and services. Central banks typically have little difficulty adjusting the available money
    supply to accommodate changes in the demand for money due to business transactions.
    Speculative demand is much harder for central banks to accommodate, which they influence by adjusting interest
    rates. A speculator may buy a currency if the return (that is the interest rate) is high enough. In general, the higher a
    country's interest rates, the greater will be the demand for that currency. It has been argued that such speculation can
    undermine real economic growth, in particular since large currency speculators may deliberately create downward
    pressure on a currency by shorting in order to force that central bank to buy their own currency to keep it stable.
    (When that happens, the speculator can buy the currency back after it depreciates, close out their position, and
    thereby take a profit.)
    For carrier companies shipping goods from one nation to another, exchange rates can often impact them severely.
    Therefore, most carriers have a CAF charge to account for these fluctuations.[7][8]

    Purchasing power of currency
    The "real exchange rate" (RER) is the purchasing power of a currency relative to another. It is based on the GDP
    deflator measurement of the price level in the domestic and foreign countries (        ), which is arbitrarily set
    equal to 1 in a given base year. Therefore, the level of the RER is arbitrarily set depending on which year is chosen
    as the base year for the GDP deflator of two countries. The changes of the RER are instead informative on the
    evolution over time of the relative price of a unit of GDP in the foreign country in terms of GDP units of the
Exchange rate                                                                                                                         21

    domestic country. If all goods were freely tradable, and foreign and domestic residents purchased identical baskets of
    goods, purchasing power parity (PPP) would hold for the GDP deflators of the two countries, and the RER would be
    constant and equal to one.

    Bilateral vs. effective exchange rate
    Bilateral exchange rate involves a currency pair, while an effective
    exchange rate is a weighted average of a basket of foreign currencies,
    and it can be viewed as an overall measure of the country's external
    competitiveness. A nominal effective exchange rate (NEER) is
    weighted with the inverse of the asymptotic trade weights. A real
    effective exchange rate (REER) adjusts NEER by appropriate foreign
    price level and deflates by the home country price level. Compared to
    NEER, a GDP weighted effective exchange rate might be more
    appropriate considering the global investment phenomenon.

    Uncovered interest rate parity (UIRP) states that an appreciation or
    depreciation of one currency against another currency might be neutralized by a change in the interest rate
    differential. If US interest rates increase while Japanese interest rates remain unchanged then the US dollar should
    depreciate against the Japanese yen by an amount that prevents arbitrage (in reality the opposite, appreciation, quite
    frequently happens in the short-term, as explained below). The future exchange rate is reflected into the forward
    exchange rate stated today. In our example, the forward exchange rate of the dollar is said to be at a discount because
    it buys fewer Japanese yen in the forward rate than it does in the spot rate. The yen is said to be at a premium.

    UIRP showed no proof of working after the 1990s. Contrary to the theory, currencies with high interest rates
    characteristically appreciated rather than depreciated on the reward of the containment of inflation and a
    higher-yielding currency.

    Balance of payments model
    This model holds that a foreign exchange rate must be at its equilibrium level - the rate which produces a stable
    current account balance. A nation with a trade deficit will experience reduction in its foreign exchange reserves,
    which ultimately lowers (depreciates) the value of its currency. The cheaper currency renders the nation's goods
    (exports) more affordable in the global market place while making imports more expensive. After an intermediate
    period, imports are forced down and exports rise, thus stabilizing the trade balance and the currency towards
    Like PPP, the balance of payments model focuses largely on trade-able goods and services, ignoring the increasing
    role of global capital flows. In other words, money is not only chasing goods and services, but to a larger extent,
    financial assets such as stocks and bonds. Their flows go into the capital account item of the balance of payments,
    thus balancing the deficit in the current account. The increase in capital flows has given rise to the asset market

    Asset market model
    The expansion in trading of financial assets (stocks and bonds) has reshaped the way analysts and traders look at
    currencies. Economic variables such as economic growth, inflation and productivity are no longer the only drivers of
    currency movements. The proportion of foreign exchange transactions stemming from cross border-trading of
    financial assets has dwarfed the extent of currency transactions generated from trading in goods and services.[9]
    The asset market approach views currencies as asset prices traded in an efficient financial market. Consequently,
    currencies are increasingly demonstrating a strong correlation with other markets, particularly equities.
    Like the stock exchange, money can be made (or lost) on the foreign exchange market by investors and speculators
    buying and selling at the right (or wrong) times. Currencies can be traded at spot and foreign exchange options
    markets. The spot market represents current exchange rates, whereas options are derivatives of exchange rates

    Manipulation of exchange rates
    Countries may gain an advantage in international trade if they manipulate the value of their currency by artificially
    keeping its value low, typically by the national central bank engaging in open market operations. It is argued that the
    People's Republic of China has succeeded in doing this over a long period of time.
    In 2010, other nations, including Japan and Brazil, attempted to devalue their currency in the hopes of subsidizing
    cheap exports and bolstering their ailing economies. A low exchange rate lowers the price of a country's goods for
    consumers in other countries but raises the price of goods, especially imported goods, for consumers in the
    manipulating country.[10]

    Exchange-rate regime
    An exchange-rate regime is the way an authority manages its currency in relation to other currencies and the
    foreign exchange market. It is closely related to monetary policy and the two are generally dependent on many of the
    same factors.
    The basic types are a floating exchange rate, where the market dictates movements in the exchange rate; a pegged
    float, where a central bank keeps the rate from deviating too far from a target band or value; and a fixed exchange
    rate, which ties the currency to another currency, mostly more widespread currencies such as the U.S. dollar or the
    euro or a basket of currencies.


    Floating rates are the most common
    exchange rate regime today. For
    example, the dollar, euro, yen, and
    British pound all are floating
    currencies. However, since central
    banks frequently intervene to avoid
    excessive appreciation or depreciation,
    these regimes are often called managed
    float or a dirty float.                            Floating exchange ratefree float regime  managed float regime  different types of
                                                    currency pegCurrency peg types: fixed exchange rate system, currency board, linked
                                                   exchange rate, fixed/crawling peg, fixed/crawling band.  Dollarizationusage of foreign

    Pegged floating currencies are pegged
    to some band or value, either fixed or periodically adjusted. Pegged floats are:
    Crawling bands
          the rate is allowed to fluctuate in a band around a central value, which is adjusted periodically. This is done at
          a preannounced rate or in a controlled way following economic indicators.
    Crawling pegs
          the rate itself is fixed, and adjusted as above.
    Pegged with horizontal bands
          the rate is allowed to fluctuate in a fixed band (bigger than 1%) around a central rate.

    Fixed rates are those that have direct convertibility towards another currency. In case of a separate currency, also
    known as a currency board arrangement, the domestic currency is backed one to one by foreign reserves. A pegged
    currency with very small bands (< 1%) and countries that have adopted another country's currency and abandoned its
    own also fall under this category.

    Dollarization occurs when the inhabitants of a country use foreign currency in parallel to or instead of the domestic
    currency. The term is not only applied to usage of the United States dollar, but generally to the use of any foreign
    currency as the national currency. Zimbabwe is a good example of dollarization since the collapse of the
    Zimbabwean dollar.

Exchange-rate flexibility                                                                                                       25

     Exchange-rate flexibility
     A flexible exchange-rate system is a monetary system that allows the exchange rate to be determined by supply and
     Every currency area must decide what type of exchange rate arrangement to maintain. Between permanently fixed
     and completely flexible however, are heterogeneous approaches. They have different implications for the extent to
     which national authorities participate in foreign exchange markets. According to their degree of flexibility,
     post-Bretton Woods-exchange rate regimes are arranged into three categories: currency unions, dollarized regimes,
     currency boards and conventional currency pegs are described as “fixed-rate regimes”; Horizontal bands, crawling
     pegs and crawling bands are grouped into “intermediate regimes”; Managed and independent floats are described as
     flexible regimes. All monetary regimes except for the permanently fixed regime experience the time inconsistency
     problem and exchange rate volatility, albeit to different degrees.

     Fixed rate programs
     In a fixed exchange rate system, the monetary authority picks rates of exchange with each other currency and
     commits to adjusting the money supply, restricting exchange transactions and adjusting other variables to ensure that
     the exchange rates do not move. All variations on fixed rates reduce the time inconsistency problem and reduce
     exchange rate volatility, albeit to different degrees.
     Under dollarization/Euroization, the US dollar or the Euro acts as legal tender in a different country. Dollarization is
     a summary description of the use of foreign currency in its capacity to produce all types of money services in the
     domestic economy. Monetary policy is delegated to the anchor country. Under dollarization exchange rate
     movements cannot buffer external shocks. The money supply in the dollarizing country is limited to what it can earn
     via exports, borrow and receive from emigrant remittances.
     A currency board enables governments to manage their external credibility problems and discipline their central
     banks by “tying their hands” with binding arrangements. A currency board combines three elements: an exchange
     rate that is fixed to another, “anchor currency”; automatic convertibility or the right to exchange domestic currency at
     this fixed rate whenever desired; and a long-term commitment to the system. A currency board system can ultimately
     be credible only if central bank holds official foreign exchange reserves sufficient to at least cover the entire
     monetary base. Exchange rate movements cannot buffer external shocks.
     A fixed peg system fixes the exchange rate against a single currency or a currency basket. The time inconsistency
     problem is reduced through commitment to a verifiable target. However, the availability of a devaluation option
     provides a policy tool for handling large shocks. Its potential drawbacks are that it provides a target for speculative
     attacks, avoids exchange rate volatility, but not necessarily persistent misalignments, does not by itself place hard
     constraints on monetary and fiscal policy and that the credibility effect depends on accompanying institutional
     measures and a visible record of accomplishment.

     Monetary union
     A currency or monetary union is a multi-country zone where a single monetary policy prevails and inside which a
     single currency or multiple substitutable currencies, move freely. A monetary union has common monetary and
     fiscal policy to ensure control over the creation of money and the size of government debts. It has a central
     management of the common pool of foreign exchange reserves, external debts and exchange rate policies. The
     monetary union has common regional monetary authority i.e. common regional central bank, which is the sole issuer
     of economy wide currency, in the case of a full currency union.
     The monetary union eliminates the time inconsistency problem within the zone and reduces real exchange rate
     volatility by requiring multinational agreement on exchange rate and other monetary changes. The potential
Exchange-rate flexibility                                                                                                         26

     drawbacks are that member countries suffering asymmetric shocks lose a stabilization tool—the ability to adjust
     exchange rates. The cost depends on the extent of asymmetric costs and the availability and effectiveness of
     alternative adjustment tools.

     Flexible exchange rate regimes
     These systems do not particularly reduce time inconsistency problems nor do they offer specific techniques for
     maintaining low exchange rate volatility.
     A crawling peg attempt to combine flexibility and stability using a rule-based system for gradually altering the
     currency's par value, typically at a predetermined rate or as a function of inflation differentials. Often used by
     (initially) high-inflation countries who peg to low inflation countries in attempt to avoid currency appreciation. At
     the margin a crawling peg provides a target for speculative attacks. Among variants of fixed exchange rates, it
     imposes the least restrictions, and may hence yield the smallest credibility benefits. The credibility effect depends on
     accompanying institutional measures and record of accomplishment.
     Exchange rate bands allow markets to set rates within a specified range; endpoints are defended through
     intervention. It provides a limited role for exchange rate movements to counteract external shocks while partially
     anchoring expectations. This system does not eliminate exchange rate uncertainty and thus motivates development of
     exchange rate risk management tools. On the margin a band is subject to speculative attacks. It does not by itself
     place hard constraints on policy, and thus provides only a limited solution to the time inconsistency problem. The
     credibility effect depends on accompanying institutional measures, a record of accomplishment and whether the band
     is firm or adjustable, secret or public, band width and the strength of the intervention requirement.
     Managed float exchange rates are determined in the foreign exchange market. Authorities can and do intervene, but
     are not bound by any intervention rule. Often accompanied by a separate nominal anchor, such as inflation target.
     The arrangement provides a way to mix market-determined rates with stabilizing intervention in a non-rule-based
     system. Its potential drawbacks are that it doesn’t place hard constraints on monetary and fiscal policy. It suffers
     from uncertainty from reduced credibility, relying on the credibility of monetary authorities. It typically offers
     limited transparency.
     In a pure float, the exchange rate is determined in the market without public sector intervention. Adjustments to
     shocks can take place through exchange rate movements. It eliminates the requirement to hold large reserves.
     However, this arrangement does not provide an expectations anchor. The exchange rate regime itself does not imply
     any specific restriction on monetary and fiscal policy.

    Dollarization occurs when the
    inhabitants of a country use foreign
    currency in parallel to or instead of the
    domestic currency as a store of value,
    unit of account, and/or medium of
    exchange      within    the     domestic
    economy.      The term is not only
    applied to usage of the United States
    dollar, but generally to the use of any
    foreign currency as the national
    currency. There are two common

    are Panama (since 1904), Ecuador
    (since 2000), and El Salvador (since
    2001). As of August 2005, the United           Worldwide official use of foreign currency or pegs:   United States dollarU.S. dollar

    After the gold standard was abandoned at the outbreak of World War I and the Bretton Woods Conference following
    World War II, some countries were desperately seeking exchange rate regimes to promote global economic stability
    and hence their own prosperity. Countries usually peg their currency to a major convertible currency. "Hard pegs"
    are extreme exchange rate regimes that demonstrate a stronger commitment to a fixed parity (i.e. currency boards) or
    relinquish control over their own currency (such as currency unions and dollarization) while "soft pegs" are more
    flexible and floating exchange rate regimes.[3] When countries choose to use a major convertible currency parallel to
Dollarization                                                                                                                    28

    or in place of their national currency, this is called the process of dollarization. The collapse of "soft" pegs in
    Southeast Asia and Latin America in the late 1990s led dollarization to become a serious policy issue.[4]
    A few cases of full dollarization until 1999 had been the consequence of political and historical factors. In all
    long-standing dollarization cases, historical and political reasons have been more influential than an evaluation of the
    effects of dollarization.[5] Panama, the most salient dollarization example, adopted the U.S. dollar as legal tender
    after its independence as a result of a constitutional ruling.[2] Ecuador and El Salvador became full dollarized
    economies in 2000 and 2001 respectively with different influential factors.[5] Ecuador underwent the process of
    dollarization to deal with a widespread political and financial crisis resulted from massive loss of credibility in its
    political and monetary institutions. In contrary, El Salvador's official dollarization was as a result of internal debates
    and in a context of stable macroeconomic fundamentals and long-standing unofficial dollarization. The euro area
    adopted the euro (€) as their common currency and sole legal tender in 1999, which might be considered as a variety
    of a full-commitment regime similar to full dollariation despite of some differences distinguishable from other

    Dollarization can occur in a number of situations. The most popular type of dollarization is unofficial dollarization
    or de facto dollarization. Unofficial dollarization happens when residents of a country choose to hold a significant
    share of their financial assets denominated in foreign currency although the foreign currency lacks the legal tender.[7]
    They hold deposits in the foreign currency because of a bad track record of the local currency, or as a hedge against
    inflation of the domestic currency.
    Official dollarization or full dollarization happens when a country adopts a foreign currency as its sole legal
    tender, and ceases to issue the domestic currency. Another effect of a country adopting a foreign currency as its own
    is that the country gives up all power to vary its exchange rate. There is a small number of countries adopting a
    foreign currency as legal tender. For example, Panama underwent a process of full dollarization by adopting the U.S.
    dollar as legal tender in 1904. This type of dollarization is also known as de jure dollarization.
    Dollarization can be used semiofficially (or officially bimonetary systems), where the foreign currency is legal
    tender alongside the domestic currency.[8]
    In literature, there is a set of related definitions of dollarization such as external liability dollarization, domestic
    liability dollarization, banking sector's liability dollarization or namely deposit dollarization and credit
    dollarlization. The external liability dollarization measures total external debt (private and public) denominated in
    foreign currencies of the economy.[8][9] Deposit dollarization can be measured as the share of dollar deposit in total
    deposit of the banking system while credit dollarization can be measured as the share of dollar credit in total credit of
    the banking system.[10]


    On trade and investment
    One of the main advantages of adopting of a strong foreign currency as sole legal tender is to reduce the transaction
    costs of trade among countries using the same currency.[11] There are at least two ways to infer this impact from
    data. The first one is a significantly negative effect of exchange rate volatility on trade in most cases, and the second
    is an association between transaction costs and the need to operate with multiple currencies.[12] Economic integration
    with the rest of the world becomes easier as a result of lowered transaction costs and stabler prices in dollar terms.[13]
    Rose (2000) applied the gravity model of trade and provided empirical evidence that countries sharing a common
    currency engage in significantly increased trade among them, and that the benefits of dollarization for trade may be
Dollarization                                                                                                                      29

    Dollarized economies can invoke greater confidence among international investors, inducing increased investments
    and growth. The elimination of the currency crisis risk due to full dollarization leads to a reduction of country risk
    premiums and then to lower interest rates.[13] These effects result in a higher level of investment. However, there is a
    positive association between dollarization and interest rates in a dual-currency economy.[15]

    On monetary and exchange rate policies
    Official dollarization helps to promote fiscal and monetary discipline and thus greater macroeconomic stability and
    lower inflation rates, to lower real exchange rate volatility, and possibly to deepen the financial system.[12] Firstly,
    dollarization helps developing countries, providing a firm commitment to stable monetary and exchange rate policies
    by forcing a passive monetary. Adopting a strong foreign currency as legal tender will help to "eliminate the
    inflation-bias problem of discretionary monetary policy".[16] Secondly, official dollarization imposes stronger
    financial constraint on the government by eliminating deficit financing by issuing money.[17] An empirical finding
    suggests that inflation has been significantly lower in dollarized nations than in non-dollarized ones.[18] The
    expected benefit of dollarization is the elimination of the risk of exchange rate fluctuations and a possible reduction
    in the country's international exposure. Though dollarization cannot eliminate the risk of an external crisis, it
    provides steadier markets as a result of eliminating fluctuations in exchange rates.[13]
    On the other hand, dollarization leads to the loss of seigniorage revenue, the loss of monetary policy autonomy, and
    the loss of the exchange rate instruments. Seigniorage revenues are the profits generated when monetary authorities
    issue currency. When adopting a foreign currency as legal tender, a monetary authority needs to withdraw the
    domestic currency and give up future seigniorage revenue. The country loses the rights to its autonomous monetary
    and exchange rate policies, even in times of financial emergency;[13][19] former chairman of the Federal Reserve
    Alan Greenspan, for example, has stated that the central bank only considers the effects of its decisions on the US
    economy.[20] In a full dollarized economy, exchange rates are indeterminate and monetary authorities cannot devalue
    the currency.[21] In a highly dollarized economy, devaluation policy is less effective in changing the real exchange
    rate because of significant pass-through effects to domestic prices.[13] However, the cost of losing an independent
    monetary policy exists when domestic monetary authorities can commit an effective counter-cyclical monetary
    policy, stabilizing the business cycle. This cost depends adversely on the correlation between the business cycle of
    the client country (the dollarized economy) and the business cycle of the anchor country.[11] In addition, monetary
    authorities in dollarized economies diminish the liquidity assurance to their banking system.[13][22]

    On banking systems
    In a fully dollarized economy, monetary authorities cannot act as lender of last resort to commercial banks by
    printing money. The alternatives to lending to the bank system may include taxation and issuing government
    debt.[23] The loss of the lender of last resort is considered a cost of full dollarization. This cost depends on the initial
    level of unofficial dollarization before moving to a full dollarized economy. This relation is negative because in a
    heavily dollarized economy, the central bank already fears difficulties in providing liquidity assurance to the banking
    system.[24] However, literature points out the existence of alternative mechanisms to provide liquidity insurance to
    banks, such as a scheme by which the international financial community charges an insurance fee in exchange for a
    commitment to lend to a domestic bank.[25]
    Commercial banks in countries where saving accounts and loans in foreign currency are allowed may face two types
    of risks:
    1. Currency mismatch risk: Assets and liabilities on the balance sheets may be in different denominations. This may
       arise if the bank converts foreign currency deposits into local currency and lends in local currency, or vice versa.
    2. Default risk: Arises if the bank uses the foreign currency deposits to lend in foreign currency.[26]
    However, dollarization eliminates the probability of a currency crisis that impacts negatively on the banking system
    through the balance sheet channel. Dollarization may reduce the possibility of systematic liquidity shortages and the

    optimal reserves in the banking system.[27] Research has shown that official dollarization has played a significant
    role in improving bank liquidity and asset quality in Ecuador and El Salvador.[28]

    Determinants of the dollarization process

    The dynamics of the flight from domestic money
    High and unanticipated inflation rates decrease the demand for domestic money and raise the demand for alternative
    assets, including foreign currency and assets dominated by foreign currency. This phenomenon is called the "flight
    from domestic money". It results in a rapid and sizable process of dollarization.[29] In countries with high inflation
    rates, the domestic currency tends to be gradually displaced by a stable currency, such as the U.S. dollar. At the
    beginning of this process, the store-of-value function of the domestic currency is replaced by the foreign currency.
    Then, the unit-of-account function of the domestic currency is displaced when many prices are quoted in a foreign
    currency. A prolonged period of high inflation will induce the domestic currency to lose its function as medium of
    exchange when the public carries out many transactions in foreign currency.[30]
    Ize and Levy-Yeyati (1998) examine the determinants of deposit and credit dollarization, concluding that
    dollarization is driven by the volatility of inflation and the real exchange rate. Dollarization increases with inflation
    volatility and decreases with the volatility of the real exchange rate.[31]

    Institutional factors
    The flight from domestic money depends on a country's institutional factors. The first factor is the level of
    development of the domestic financial market. An economy with a well-developed financial market can offer a set of
    alternative financial instruments dominated in domestic currency, reducing the role of foreign currency as an
    inflation hedge. The pattern of the dollarization process also varies across countries with different foreign exchange
    and capital controls. In a country with strict foreign exchange regulations, the demand for foreign currency will be
    satisfied in the holding of foreign currency assets abroad and outside the domestic banking system. This demand
    often puts pressure on the parallel market of foreign currency and on the country's international reserves.[29]
    Evidence for this pattern is given in the absence of dollarization during the pre-reform period in most transition
    economies, because of constricted controls on foreign exchange and the banking system.[32] In contrary, by
    facilitating the domestic holding of foreign currency, a country might mitigate the shift of assets abroad and
    strengthen its external reserves in exchange for a dollarization process. However, the effect of this regulation on the
    pattern of dollarization depends on the public's expectations of macroeconomic stability and the sustainability of the
    foreign exchange regime.[29]

    Fixed exchange rate
    A fixed exchange rate, sometimes called a pegged exchange rate, is also referred to as the Tag of particular Rate,
    which is a type of exchange rate regime where a currency's value is fixed against the value of another single currency
    or to a basket of other currencies, or to another measure of value, such as gold.
    A fixed exchange rate is usually used to stabilize the value of a currency against the currency it is pegged to. This
    makes trade and investments between the two countries easier and more predictable and is especially useful for small
    economies in which external trade forms a large part of their GDP.
    It can also be used as a means to control inflation. However, as the reference value rises and falls, so does the
    currency pegged to it. In addition, according to the Mundell–Fleming model, with perfect capital mobility, a fixed
    exchange rate prevents a government from using domestic monetary policy in order to achieve macroeconomic
    There are no major economic players that use a fixed exchange rate (except the countries using the euro and the
    Chinese yuan). The currencies of the countries that now use the euro are still existing (for old bonds). The rates of
    these currencies are fixed with respect to the euro and to each other. The most recent such country to discontinue
    their fixed exchange rate was the People's Republic of China, which did so in July 2005.[1]

    Typically, a government wanting to maintain a fixed exchange rate does so by either buying or selling its own
    currency on the open market. This is one reason governments maintain reserves of foreign currencies. If the
    exchange rate drifts too far below the desired rate, the government buys its own currency in the market using its
    reserves. This places greater demand on the market and pushes up the price of the currency. If the exchange rate
    drifts too far above the desired rate, the government sells its own currency, thus increasing its foreign reserves.
    Another, less used means of maintaining a fixed exchange rate is by simply making it illegal to trade currency at any
    other rate. This is difficult to enforce and often leads to a black market in foreign currency. Nonetheless, some
    countries are highly successful at using this method due to government monopolies over all money conversion. This
    was the method employed by the Chinese government to maintain a currency peg or tightly banded float against the
    US dollar. Throughout the 1990s, China was highly successful at maintaining a currency peg using a government
Fixed exchange rate                                                                                                                                34

    monopoly over all currency conversion between the yuan and other currencies.[2][3]
    On the 6 September 2011, the Swiss National Bank has imposed a franc ceiling, for first time in three decades,
    against the euro. In 1978 a franc ceiling was set versus the Deutsche Mark to stem currency gains.

    The main criticism of a fixed exchange rate is that flexible exchange rates serve to adjust the balance of trade.[4]
    When a trade deficit occurs, there will be increased demand for the foreign (rather than domestic) currency which
    will push up the price of the foreign currency in terms of the domestic currency. That in turn makes the price of
    foreign goods less attractive to the domestic market and thus pushes down the trade deficit. Under fixed exchange
    rates, this automatic rebalancing does not occur.
    Governments also have to invest many resources in getting the foreign reserves to pile up in order to defend the
    pegged exchange rate. Moreover a government, when having a fixed rather than dynamic exchange rate, cannot use
    monetary or fiscal policies with a free hand. For instance, by using reflationary tools to set the economy rolling (by
    decreasing taxes and injecting more money in the market), the government risks running into a trade deficit. This
    might occur as the purchasing power of a common household increases along with inflation, thus making imports
    relatively cheaper.
    Additionally, the stubbornness of a government in defending a fixed exchange rate when in a trade deficit will force
    it to use deflationary measures (increased taxation and reduced availability of money), which can lead to
    unemployment. Finally, other countries with a fixed exchange rate can also retaliate in response to a certain country
    using the currency of theirs in defending their exchange rate.

    Fixed exchange rate regime versus capital control
    The belief that the fixed exchange rate regime brings with it stability is only partly true, since speculative attacks
    tend to target currencies with fixed exchange rate regimes, and in fact, the stability of the economic system is
    maintained mainly through capital control. A fixed exchange rate regime should be viewed as a tool in capital
    For instance, China has allowed free exchange for current account transactions since December 1, 1996. Of more
    than 40 categories of capital account, about 20 of them are convertible. These convertible accounts are mainly
    related to foreign direct investment. Because of capital control, even the renminbi is not under the managed floating
    exchange rate regime, but free to float, and so it is somewhat unnecessary for foreigners to purchase renminbi.

    Floating exchange rate
    A floating exchange rate or fluctuating exchange rate is a type of exchange rate regime wherein a currency's value
    is allowed to fluctuate according to the foreign exchange market. A currency that uses a floating exchange rate is
    known as a floating currency.

    Economic rationale
    There are economists who think that in most circumstances, floating exchange rates are preferable to fixed exchange
    rates. As floating exchange rates automatically adjust, they enable a country to dampen the impact of shocks and
    foreign business cycles, and to preempt the possibility of having a balance of payments crisis.
    However, in certain situations, fixed exchange rates may be preferable for their greater stability and certainty. That
    may not necessarily be true, considering the results of countries that attempt to keep the prices of their currency
    "strong" or "high" relative to others, such as the UK or the Southeast Asia countries before the Asian currency crisis.
    The debate of making a choice between fixed and floating exchange rate regimes is set forth by the
    Mundell–Fleming model, which argues that an economy (or the government) cannot simultaneously maintain a fixed
    exchange rate, free capital movement, and an independent monetary policy. It must choose any two for control and
    leave the other to market forces.
    The primary argument for a floating exchange rate is that it allows monetary policies to be useful for other purposes.
    Under fixed rates, monetary policy is committed to the single goal of maintaining exchange rate at its announced
    level. Yet the exchange rate is only one of many macro economic variable that monetary policy can influence. A
    system of floating exchange rate leaves monetary policy makers free to pursue other goals such as stabilizing
    employment or prices.
    In cases of extreme appreciation or depreciation, a central bank will normally intervene to stabilize the currency.
    Thus, the exchange rate regimes of floating currencies may more technically be known as a managed float. A
    central bank might, for instance, allow a currency price to float freely between an upper and lower bound, a price
    "ceiling" and "floor". Management by the central bank may take the form of buying or selling large lots in order to
    provide price support or resistance or, in the case of some national currencies, there may be legal penalties for
    trading outside these bounds.

    Floating currency
    A floating currency is a currency that uses a floating exchange rate as its exchange rate regime. A floating currency
    is contrasted with a fixed currency.
    In the modern world, the majority of the world's currencies are floating. Central banks often participate in the
    markets to attempt to influence exchange rates. Such currencies include the most widely traded currencies: the
    United States dollar, the euro, the Norwegian krone, the Japanese yen, the British pound, the Swiss franc[1] and the
    Australian dollar. The Canadian dollar most closely resembles the ideal floating currency as the Canadian central
    bank has not interfered with its price since it officially stopped doing so in 1998.[2]
    The US dollar[3] runs a close second with very little change in its foreign reserves; by contrast, Japan[4] and the
    United Kingdom[5] intervene to a greater extent.
    From 1946 to the early 1970s, the Bretton Woods system made fixed currencies the norm; however, in 1971, the
    United States government would no longer uphold the dollar exchange at 1/35th of an ounce of gold, so that the US
Floating exchange rate                                                                                                                         36

    dollar was no longer a fixed currency. After the 1973 Smithsonian Agreement, most of the world's currencies
    followed suit.
    A floating currency is one where targets other than the exchange rate itself are used to administer monetary policy.
    See open market operations.

    Fear of floating
    A free floating exchange rate increases foreign exchange volatility. There are economists who think that this could
    cause serious problems, especially in emerging economies. These economies have a financial sector with one or
    more of following conditions:
    • high liability dollarization
    • financial fragility
    • strong balance sheet effects
    When liabilities are denominated in foreign currencies while assets are in the local currency, unexpected
    depreciations of the exchange rate deteriorate bank and corporate balance sheets and threaten the stability of the
    domestic financial system.
    For this reason emerging countries appear to face greater fear of floating, as they have much smaller variations of the
    nominal exchange rate, yet face bigger shocks and interest rate and reserve movements.[6] This is the consequence of
    frequent free floating countries' reaction to exchange rate movements with monetary policy and/or intervention in the
    foreign exchange market.
    The number of countries that present fear of floating increased significantly during the 1990s.[7]

    Linked exchange rate
    A linked exchange rate system is a type of exchange rate regime to link the exchange rate of a currency to another.
    It is the exchange rate system implemented in Hong Kong to stabilise the exchange rate between the Hong Kong
    dollar (HKD) and the United States dollar (USD). The Macao pataca (MOP) is similarly linked to the Hong Kong
    Unlike a fixed exchange rate system, the government or central bank does not actively interfere in the foreign
    exchange market by controlling supply and demand of the currency in order to influence the exchange rate. The
    exchange rate is instead stabilized by an exchange mechanism, whereby the Hong Kong Monetary Authority
    (HKMA) authorises note-issuing banks are to issue new banknotes provided that they deposit an equivalent value of
    US dollars with the HKMA.

    As a response to the Black Saturday crisis in 1983, the linked exchange rate system was adopted in Hong Kong on
    October 17, 1983 through the currency board system.[1] The redemption of certificates of indebtedness (for backing
    the banknotes) were sent out by note-issuing banks to peg the domestic currency against the US dollar at an internal
    fixed rate of HKD 7.80 = USD 1.[2]
    The Hong Kong Monetary Authority (HKMA), Hong Kong's de facto central bank, authorised note-issuing banks are
    to issue banknotes. These banks are required to have the same amount of USD to issue banknotes. The HKMA
    guarantees to exchange USD into HKD, or vice versa, at the rate of 7.80. When the market rate is below 7.80, the
    banks will convert USD for HKD from the HKMA, HKD supply will be decreased, and the market rate will climb
    back to 7.80. The same mechanism also works when the market rate is above 7.80, and the banks will convert HKD
    for USD.
    In practice, the HKMA also set a lower limit at 7.80 (7.85 as an upper limit and 7.75 as a lower limit since May 18,
    2005) for the HKD to flow within. The HKMA will sell or buy HKD in the market when the exchange rate is at (or
    extremely close) the lower limit and upper limit respectively. The HKD is backed by one of the world's largest
    foreign exchange reserves, which is several times the amount of money supplied in circulation.

    Managed float regime
    Managed float regime is the current international financial environment in which exchange rates fluctuate from day
    to day, but central banks attempt to influence their countries' exchange rates by buying and selling currencies. It is
    also known as a dirty float.
    In an increasingly integrated world economy, the currency rates impact any given country's economy through the
    trade balance. In this aspect, almost all currencies are managed since central banks or governments intervene to
    influence the value of their currencies.

    Futures exchange
    A futures exchange or futures market is a central financial exchange where people can trade standardized futures
    contracts; that is, a contract to buy specific quantities of a commodity or financial instrument at a specified price
    with delivery set at a specified time in the future. These types of contracts fall into the category of derivatives. Such
    instruments are priced according to the movement of the underlying asset (stock, physical commodity, index, etc.).
    The aforementioned category is named "derivatives" because the value of these instruments is derived from another
    asset class.

    History of futures exchanges
    One of the earliest written records of futures trading is in Aristotle's Politics. He tells the story of Thales, a poor
    philosopher from Miletus who developed a "financial device, which involves a principle of universal application".
    Thales used his skill in forecasting and predicted that the olive harvest would be exceptionally good the next autumn.
    Confident in his prediction, he made agreements with local olive-press owners to deposit his money with them to
    guarantee him exclusive use of their olive presses when the harvest was ready. Thales successfully negotiated low
    prices because the harvest was in the future and no one knew whether the harvest would be plentiful or pathetic and
    because the olive-press owners were willing to hedge against the possibility of a poor yield. When the harvest-time
    came, and a sharp increase in demand for the use of the olive presses outstripped supply, he sold his future use
    contracts of the olive presses at a rate of his choosing, and made a large quantity of money.[1] It should be noted,
    however, that this is a very loose example of futures trading and, in fact, more closely resembles an option contract,
    given that Thales was not obliged to use the olive presses if the yield was poor.
    The first modern organized futures exchange began in 1710 at the Dojima Rice Exchange in Osaka, Japan.[2]
    The United States followed in the early 19th century. Chicago has the largest future exchange in the world, the
    Chicago Mercantile Exchange. Chicago is located at the base of the Great Lakes, close to the farmlands and cattle
    country of the Midwest, making it a natural center for transportation, distribution, and trading of agricultural
    produce. Gluts and shortages of these products caused chaotic fluctuations in price, and this led to the development
    of a market enabling grain merchants, processors, and agriculture companies to trade in "to arrive" or "cash forward"
    contracts to insulate them from the risk of adverse price change and enable them to hedge. In March 2008 the
    Chicago Mercantile Exchange announced its acquisition of NYMEX Holdings, Inc., the parent company of the New
    York Mercantile Exchange and Commodity Exchange. CME's acquisition of NYMEX was completed in August
Futures exchange                                                                                                                 40

    For most exchanges, forward contracts were standard at the time. However, most forward contracts were not honored
    by both the buyer and the seller. For instance, if the buyer of a corn forward contract made an agreement to buy corn,
    and at the time of delivery the price of corn differed dramatically from the original contract price, either the buyer or
    the seller would back out. Additionally, the forward contracts market was very illiquid and an exchange was needed
    that would bring together a market to find potential buyers and sellers of a commodity instead of making people bear
    the burden of finding a buyer or seller.
    In 1848 the Chicago Board of Trade (CBOT–) was formed. Trading was originally in forward contracts; the first
    contract (on corn) was written on March 13, 1851. In 1865 standardized futures contracts were introduced.
    The Chicago Produce Exchange was established in 1874, renamed the Chicago Butter and Egg Board in 1898 and
    then reorganised into the Chicago Mercantile Exchange (CME) in 1919. Following the end of the postwar
    international gold standard, in 1972 the CME formed a division called the International Monetary Market (IMM) to
    offer futures contracts in foreign currencies: British pound, Canadian dollar, German mark, Japanese yen, Mexican
    peso, and Swiss franc.
    In 1881 a regional market was founded in Minneapolis, Minnesota, and in 1883 introduced futures for the first time.
    Trading continuously since then, today the Minneapolis Grain Exchange (MGEX) is the only exchange for hard red
    spring wheat futures and options.[3]
    The 1970s saw the development of the financial futures contracts, which allowed trading in the future value of
    interest rates. These (in particular the 90‑day Eurodollar contract introduced in 1981) had an enormous impact on the
    development of the interest rate swap market.
    Today, the futures markets have far outgrown their agricultural origins. With the addition of the New York
    Mercantile Exchange (NYMEX) the trading and hedging of financial products using futures dwarfs the traditional
    commodity markets, and plays a major role in the global financial system, trading over $1.5 trillion per day in 2005.
    The recent history of these exchanges (Aug 2006) finds the Chicago Mercantile Exchange trading more than 70% of
    its Futures contracts on its "Globex" trading platform and this trend is rising daily. It counts for over $45.5 billion of
    nominal trade (over 1 million contracts) every single day in "electronic trading" as opposed to open outcry trading of
    futures, options and derivatives.
    In June 2001 IntercontinentalExchange (ICE) acquired the International Petroleum Exchange (IPE), now ICE
    Futures, which operated Europe’s leading open-outcry energy futures exchange. Since 2003 ICE has partnered with
    the Chicago Climate Exchange (CCX) to host its electronic marketplace. In April 2005 the entire ICE portfolio of
    energy futures became fully electronic.
    In 2006 the New York Stock Exchange teamed up with the Amsterdam-Brussels-Lisbon-Paris Exchanges
    "Euronext" electronic exchange to form the first transcontinental futures and options exchange. These two
    developments as well as the sharp growth of internet futures trading platforms developed by a number of trading
    companies clearly points to a race to total internet trading of futures and options in the coming years.
    In terms of trading volume, the National Stock Exchange of India in Mumbai is the largest stock futures trading
    exchange in the world, followed by JSE Limited in Sandton, Gauteng, South Africa.[4]

    Nature of contracts
    Exchange-traded contracts are standardized by the exchanges where they trade. The contract details what asset is to
    be bought or sold, and how, when, where and in what quantity it is to be delivered. The terms also specify the
    currency in which the contract will trade, minimum tick value, and the last trading day and expiry or delivery month.
    Standardized commodity futures contracts may also contain provisions for adjusting the contracted price based on
    deviations from the "standard" commodity, for example, a contract might specify delivery of heavier USDA Number
    1 oats at par value but permit delivery of Number 2 oats for a certain seller's penalty per bushel.
Futures exchange                                                                                                                 41

    Before the market opens on the first day of trading a new futures contract, there is a specification but no actual
    contracts exist. Futures contracts are not issued like other securities, but are "created" whenever Open interest
    increases; that is, when one party first buys (goes long) a contract from another party (who goes short). Contracts
    are also "destroyed" in the opposite manner whenever Open interest decreases because traders resell to reduce their
    long positions or rebuy to reduce their short positions.
    Speculators on futures price fluctuations who do not intend to make or take ultimate delivery must take care to "zero
    their positions" prior to the contract's expiry. After expiry, each contract will be settled, either by physical delivery
    (typically for commodity underlyings) or by a cash settlement (typically for financial underlyings). The contracts
    ultimately are not between the original buyer and the original seller, but between the holders at expiry and the
    exchange. Because a contract may pass through many hands after it is created by its initial purchase and sale, or even
    be liquidated, settling parties do not know with whom they have ultimately traded.
    Compare this with other securities, in which there is a primary market when an issuer issues the security, and a
    secondary market where the security is later traded independently of the issuer. Legally, the security represents an
    obligation of the issuer rather than the buyer and seller; even if the issuer buys back some securities, they still exist.
    Only if they are legally cancelled they can disappear.

    The contracts traded on futures exchanges are always standardized. In principle, the parameters to define a contract
    are endless (see for instance in futures contract). To make sure liquidity is high, there is only a limited number of
    standardized contracts.

    Clearing and settlement
    There is usually a division of responsibility between provision of trading facility, and that of clearing and settlement
    of those trades. While derivative exchanges like the CBOE and LIFFE take responsibility for providing efficient,
    transparent and orderly trading environments, settlement of the resulting trades are usually handled by clearing
    houses that serve as central counterparties to trades done in the respective exchanges. For instance, the Options
    Clearing Corporation (OCC) and LCH.Clearnet (London Clearing House) respectively are the clearing corporations
    for CBOE and LIFFE. A well known exception to this is the case of Chicago Mercantile Exchange and ICE, which
    clear trades themselves.

    Central counterparty
    Derivative contracts are leveraged positions whose value is volatile. They are usually more volatile than their
    underlying asset. This can lead to credit risk, in particular counterparty risk, those situations where one party to a
    trade loses a big sum of money and is unable to honor its settlement obligation. In a safe trading environment, the
    parties to a trade need to be assured that their counterparty will honor the trade, no matter how the market has
    moved. This requirement can lead to messy arrangements like credit assessment, setting of trading limits and so on
    for each counterparty, and take away most of the advantages of a centralised trading facility. To prevent this, a
    clearing house interposes themselves as counterparties to every trade and extend guarantee that the trade will be
    settled as originally intended. This action is called novation. As a result, trading firms take no risk on the actual
    counterparty to the trade, but on the clearing corporation. The clearing corporation is able to take on this risk by
    adopting an efficient margining process.

    Margin and Mark-to-Market
    A margin is collateral that the holder of a financial instrument has to deposit to cover some or all of the credit risk of
    their counterparty, in this case the central counterparty clearing houses. Clearing houses charge two types of
    margins: the Initial Margin and the Mark-To-Market margin (also referred to as Variation Margin).
    The Initial Margin is the sum of money (or collateral) to be deposited by a firm to the clearing corporation to cover
    possible future loss in the positions (the set of positions held is also called the portfolio) held by a firm.Several
    popular methods are used to compute initial margins. They include the CME-owned SPAN (a grid simulation
    method used by the CME and about 70 other exchanges), STANS (a Monte Carlo simulation based methodology
    used by the OCC), TIMS (earlier used by the OCC, and still being used by a few other exchanges like the Bursa
    The Mark-to-Market Margin (MTM margin) on the other hand is the margin collected to offset losses (if any) that
    have already been incurred on the positions held by a firm. This is computed as the difference between the cost of
    the position held and the current market value of that position. If the resulting amount is a loss, the amount is
    collected from the firm; else, the amount may be returned to the firm (the case with most clearing houses) or kept in
    reserve depending on local practice. In either case, the positions are 'marked-to-market' by setting their new cost to
    the market value used in computing this difference. The positions held by the clients of the exchange are
    marked-to-market daily and the MTM difference computation for the next day would use the new cost figure in its
    Clients hold a margin account with the exchange, and every day the swings in the value of their positions is added to
    or deducted from their margin account. If the margin account gets too low, they have to replenish it. In this way it is
    highly unlikely that the client will not be able to fulfill his obligations arising from the contracts. As the clearing
    house is the counterparty to all their trades, they only have to have one margin account. This is in contrast with OTC
    derivatives, where issues such as margin accounts have to be negotiated with all counterparties.

    Each exchange is normally regulated by a national governmental (or semi-governmental) regulatory agency:
    •   In Australia, this role is performed by the Australian Securities and Investments Commission.
    •   In the Chinese mainland, by the China Securities Regulatory Commission.
    •   In Hong Kong, by the Securities and Futures Commission.
    •   In India, by the Securities and Exchange Board of India and Forward Markets Commission (FMC)
    •   In Japan, by the Financial Services Agency.
    •   In Pakistan, by the Securities and Exchange Commission of Pakistan.
    •   In Singapore by the Monetary Authority of Singapore.
    •   In the UK, futures exchanges are regulated by the Financial Services Authority.
    •   In the USA, by the Commodity Futures Trading Commission.
    •   In Malaysia, by the Securities Commission Malaysia.
    •   In Spain, by the Comisión Nacional del Mercado de Valores (CNMV).
    •   In Brazil, by the Comissão de Valores Mobiliários (CVM).
    •   In South Africa, by the Financial Services Board (South Africa).

    Retail foreign exchange platform
    Retail foreign exchange trading is a small segment of the large foreign exchange market. In 2007 it had been
    speculated that volume from retail foreign exchange trading represents 5 percent of the whole foreign exchange
    market which amounts to $50–100 billion[1][2] in daily trading turnover. The retail foreign exchange market has been
    growing. In general retail customers are able to trade spot currencies. Due to the increasing tendency in the past
    years of the gradual shift from traditional intrabank 'paper' trading to the more advanced and accurate electronic
    trading, there has been spur in software development in this field. This change provided different types of trading
    platforms and tools intended for the use by banks, portfolio managers, retail brokers and retail traders.
    One of the most important tools required to perform a foreign exchange transaction is the trading platform providing
    retail traders and brokers with accurate currency quotes.

    History and new developments
    Electronic foreign exchange trading was first introduced to the retail public in 1996. The development was closely
    related with the development of the internet and can be roughly split into three waves.

    First wave 1996-2001
    In 1996 several forex brokers started offering electronic retail forex trading facilities, some developed their own
    platform while those who lacked the sufficient tools to developed their own trading platforms used software based on
    ACT foreign exchange trading technology. The 1st retail FX brokers were MG Forex, The Matchbook FX ECN,
    Global Forex Trading (GFT), CMC Markets, FXCM, Saxo Bank (then known as Midas) and a handful of others.
    Most except CMC, Saxo & Matchbook FX were based on the ACT foreign exchange trading technology and GUI.
    These platforms were good enough at the time but required constant investments in research and development and
    this development cost too much.

    Second wave 2001-2006
    The second wave started in the early 2000s when several software companies entered the retail foreign exchange
    trading market by launching their own versions of trading platforms, like Apbg Group, Ctn Systems, Tradestation
    and MetaTrader 4 from MetaQuotes Software which allowed the users to create their own trading indicators and
    automatic strategies. Typically these versions were cumbersome for both front-end users (retail traders) and
    back-end users (retail brokers) due to the misunderstanding of the developers about the foreign exchange market and
    also because of the insufficient programming tools/languages at the time. Simultaneously most of the retail brokers
    kept using and developing their own systems as they waited for better platforms which were yet to be developed.
Retail foreign exchange platform                                                                                                          44

    Third wave 2006-2011
    Starting in 2007, web based trading platforms started to emerge. These platforms put much stronger emphasis on the
    user interface (GUI) making it more accessible to the retail traders while making trading on it very simple and
    intuitive. Some platforms also started to focus on social networking as a way to attract new users, after the
    emergence of Facebook, Twitter and other social media networks. Social trading has been growing intensely in the
    last years, especially after platforms like ZuluTrade, Currensee,, eToro or FXStat appeared.
    Moreover, a very strong emphasis was put on the back-end which allowed the retail brokers better control over their
    operations, better reporting and accurate system and ways to manage marketing campaigns.
    Gradually this wave is replacing the previous second wave with a major shift now to the friendlier and more intuitive
    systems of the third wave which according to Aite Group are necessary in order to maintain growth.[3]

    Peer-to-peer trading systems
    In the South Pacific, "peer-to-peer" foreign exchange services, supported by local government agencies, are
    emerging in an attempt to reduce transaction costs to heavily remittance-dependent nations, such as Tonga and

    In 2006 a few banks started offering foreign exchange trading services to individual traders and money managers.
    DBFX and CitiFX Pro are some of the banks that were offering this service. However Deutsche Bank shut down its
    DBFX service in 2011.
