  the Money Supply Process
          Chapter 17
        Banking Regulation
• Many central banks require banks to keep
  some fixed fraction of checking deposits
  as deposits at central bank.
• Required reserve ratio - 0 ≤ rr < 1.
• China most prominently uses the reserve
  ratio as a measure of monetary policy.

          The Monetary Base
• The monetary base, also called “high powered
  money” consists of:
        C    Currency in the Hands of the Public
       +R     + Reserves of the Banking System
      =MB                      = Monetary Base



 • Monetary base is typically the monetary
 liabilities of the central bank .

           Balance Sheets
• Central banks like all banks have balance
  sheets with assets and liabilities.
• Hong Kong has some unique monetary
  institutions which may be most usefully
  examined in the contrast with US central
  bank (which is examined closely in the
  textbook).

               Assets
• Government Securities: A large number of
  central banks (but not HK) hold domestic
  currency government bonds as main holdings of
  central bank.
  – These are used to conduct monetary policy
• Foreign Reserves: Central banks typically hold
  some foreign currency assets. Foreign reserves
  are also held by Treasury/Finance Ministry.

• Loans: Central banks also conduct
  monetary policy by lending reserves to
  banks.
• Miscellaneous:
  – Float: Checks in the process of the payment
    system.
  – Gold Reserves, Stocks Etc.

           Monetary Liabilities

• Currency: Paper Money is typically issued by
  central bank. Coins are sometimes (as in HK)
     • Currency Held by Non Bank Public [C]
     • Currency Held by Banks aka “Vault Cash”:
       includes money ATM machines.
• Deposits of Banks: Banks keep accounts at the        [R]
  central bank to facilitate payments and meet
  regulatory requirements.
    An average of 4.6% of currency in circulation in
    USA is vault cash. In HK, 7.5%

                Currency
• Hong Kong’s central bank does not print money.
• Bank of China, HSBC, and Standard Chartered
  print banknotes but…
   – the banks can only issue paper notes if they
     buy licenses from the central bank with US$
     at a rate of $1 per HK$7.8 printed.
• The Licenses are called Certificates of
  Indebtedness Certificates issued by the
  Financial Secretary to be held by note-
  issuing banks as cover for the banknotes
  they issue.
• CI’s appear as liabilities on HKMA balance
  sheet.
   Certificates of Indebtedness
increase when currency increases
                              Coins

   • Coins (and recent 10 Banknotes) are
     issued by the central bank unlike the
     USA where they are issued by the
     Treasury.

  Terms” by HKMA.see http://www.hkma.gov.hk
   Reserves: Clearing Balances
• The reserve requirement in HK is zero.
  Banks must only have enough reserves to
  meet all of their payment obligations.
• Clearing Account: The accounts
  maintained with the HKMA for settling inter-
  bank balances and payments between
  banks and the HKMA.
  – Aggregate Balances: The sum of balances
    maintained by banks in clearing accounts at the
    central bank.
Reserves: Exchange Fund Bills
• Exchange Fund Bills and Notes Debt
  Instruments issued by the HKMA for the
  account of the Exchange Fund.
• Since 1990, the Exchange Fund has sold
  short-term bonds (stretching the maturity
  structure as time goes on ).
• Exchange Fund bonds are listed on HKEX
  and traded in secondary markets.
Should government debt be part of
       the monetary base?
• Exchange Fund Paper can be held by anyone,
  but large share is owned by local banks.
  Therefore, they can be thought of as being
  mostly secondary reserves of banks.
• ExFund paper is held primarily for HK$ liquidity
  management purposes.
• These instruments are fully backed by Foreign
  Reserves. The HKMA has undertaken that new
  Exchange Fund paper will only be issued when
  there is an inflow of funds.

Changing the Monetary Base
  4 Ways Central Banks Change
         Monetary Base
1. Open Market Operation – Sell/Purchase
   Government Securities
2. Discount Window – Bank borrows funds
   from Central Bank
3. Foreign Exchange Intervention
4. Printing Currency
              T-Accounts
• T-Accounts are a handy tool for examining
  the effects that any transaction has on
  balance sheets.
• A bank transaction will change both
  liabilities and assets (and possibly net
  worth). The total change in liabilities plus
  net worth must always equal the total
  change in assets.
             Open Market Purchase:
          The Fed Purchases $100 of T-Bills from Bank A


• Fed credits the reserve   Fed Balance Sheet
  accounts of Bank A which Assets             Liabilities
  increases its liabilities
  and takes possession of   +100 T-Bills      + 100 Reserves
  an equal value of
  securities as assets.

                                 Bank A Balance Sheet
• Bank A gets an extra            Assets                Liabilities
  amount of reserves and
                                  +100 Reserves
  loses an equal amount of
  securities.                     -100 T-Bills
              Exchange Rate
•   The exchange rate between any
    currency and the US dollar can be
    written in two ways.
    1. S: # of Currency Units per dollar (e.g.
       7.8HK$ per US$)
    2. Ex: # of Dollars per Currency Unit (e.g.
•   For most currencies (exceptions € & £),
    the former definition prevails.
           Currency Market Intervention
Central Bank buys 100/S foreign currency from Bank.
• Central Bank          Central Bank Balance Sheet
  credits Bank A
  reserves with 100      Assets                         Liabilities
  of domestic            +100 Foreign Reserves*         + 100 Reserves

 Convertibility Undertaking: Currency
• Currency Board “When the three NIBs issue
  banknotes, they are required to submit US dollars
  (at HK$7.80=US$1) to the HKMA for the account of
  the Exchange Fund in return for Certificates of
  Indebtedness (which are required by law as
  backing for the banknotes issued).”

      Clearing Accounts Reserves
• 1996-2005 The HKMA has an undertaking to
  convert Hong Kong dollars in clearing accounts
  into US dollars at rate of HK$7.8 to US$1
  – When the exchange rate depreciates to $7.8, the
    HKMA allows licensed banks to trade clearing
    balances for US dollars.

• May 2005 Under the strong-side Convertibility
  Undertaking, the HKMA undertakes to buy US
  dollars from licensed banks at 7.75. Under the
  weak-side Convertibility Undertaking, the HKMA
  undertakes to sell US dollars at 7.85.
   – Within the Convertibility Zone between 7.75 and 7.85,
     the HKMA may choose to conduct market operations
     ….

The Money Supply Process
     Fractional Reserve Banking
• Banks keep only a fraction of any deposits
  they receive on hand in the form of vault.
  The rest is used to acquire other assets,
  especially loans.
• Reserves- Deposit Ratio:
The fraction of deposits kept as reserves is
  the Reserves-Deposit Ratio.
  – D = Demand Deposits (we can think of this as
    equivalent to checking accounts).
            Liquidity Portfolio
• Savers keep some of their asset portfolio in
  liquid assets.
• We can divide up liquid assets into currency and
  deposits
• Currency-Deposit Ratio:
  – Bank deposits and currency are both assets which
    will be part of the portfolios of savers.
     Monetary Base & Money Supply
• A given increase in the monetary base
  creates money on a greater than 1 for 1
  basis.
• Each $1 of reserves can be used to
  back up more than $1 of deposits which
  will exist as the stock of money.
• Money supply consists of currency in
  circulation plus some level of bank
  deposits.
                  M1 = C + D
OMO & Multiple Deposit Expansion
• The simplest way to see how fractional
  reserve banking causes multiple money
  expansion is to assume           .        .
• In our example, we will assume        .
      Central bank open market purchase
    increases Bank A’s reserves by $100K.
                           Bank A

                M1 Multiplier
• In the more general case, the M1 multiplier can
  be derived by the ratio of M1 to the monetary
  base.




• As long as the reserve ratio is less than 1, the
  money multiplier is greater than 1.
• Multiplier is decreasing in reserve-deposit ratio
  and decreasing in cash-deposit ratio.

    Determinants of Reserve Ratio
1. Regulatory Requirements – Some regulatory
   regimes have minimum reserve levels.
                     Reserve Ratio =
     Required Reserves Ratio + Excess Reserves Ratio
                     (R/D) = rr + ER/D
2. Market Interest Rates – If assets are held in the form
   of reserves, banks lose opportunity to get interest
   income. The greater is the interest rate, the less
   reserves held.
3. Volatility of Deposit Outflows – If deposit outflows are
   likely to be large, banks hold more reserves.

         Determinants of C/D
1. Wealth – Holding some cash is probably a
   necessity. Wealthier people hold less of their
   wealth in the form of cash.
2. Returns on Deposits – If the deposit interest rate
   is high, currency deposit ratio is small.
3. Risk – High default risk of bank deposits
   encourages cash holdings. Low crime risk
   encourages cash holdings.
4. Liquidity – Difficulty in using deposits in
   transactions encourages cash holdings.
5. Value of Anonymity Premium – High levels of
   black market activity/tax avoidance encourages
   cash holdings.

Money Multiplier and
 Monetary Policy
   Money as a Nominal Anchor
• One way to commit to a low inflation policy
  is to commit to low money growth a tenet
  of a school of macroeconomic analysis
  referred to as “monetarism”
• Timely reporting of the supply of money
  can help to build credibility for low inflation.
Problem: Central bank cannot control the
  money supply. Can only directly control
  the monetary base.

     Money
    Multiplier
•The history of
volatility of the M2
multiplier has
convinced the Fed
that it is impossible to
control the money
supply through their
control of the
monetary base.
• Over the past
  8 years, the
  M2 multiplier
  has been
  more volatile
  in HK than the
  USA.
 Can the Central Bank Control the
         Money Multiplier
• The government’s main tool to control the
  multiplier is the required reserve ratio. However,
  this regulatory tool is less effective if banks
  reserve holdings exceed requirements.
• In other economies, such as the US and
  Euroland, the reserve requirement is low and the
  regulation seldom binds.
  – Technological change has allowed banks to evade
    reserve requirements.
• In many economies, including HK, Australia,
  Canada and the UK there is no reserve
  requirement.
 HK Dollar Peg: Fully Backed?
• The convertibility undertaking requires the
  HKMA to convert foreign currency into
  domestic currency at a rate of
  HK$7.8:US$1.
• Does the monetary authority have enough
  US dollars to meet this undertaking?
