The Basle Framework



 Basle I had provisions for:


       Tier I capital or core capital


       Tier II capital or supplementary capital

 Risk capital = 8% of total risk weighted assets

 Tier I capital = 4% of total risk weighted assets




                                                     1
Basle II

  Basle II emerged out of the criticism of Basle I.

   Some of the gaps in Basle I were:

         -      Simplistic and rigid rules

         -    Insufficient alignment of regulatory and
         economic risk based capital

         -     Regulatory arbitrage – Securitisation for
         example can take assets off balance sheet
         and reduce the capital requirement.

The three pillars of Basle 2



    Minimum capital requirements
    Supervisory review
    Market discipline




                                    3
Total risk charge

   Market

   Credit

   Operational

   Total risk charge
    = credit risk + market risk + operational risk charge
    ( Total remains 8%)

More Flexibility and Risk Sensitivity


      The existing Capital Accord           The new Capital Accord

    Focus on a single risk measure.    More emphasis on banks' own
                                          internal methodologies, supervisory
                                          review, and market discipline.

    One size fits all.                 Flexibility, menu of approaches,
                                          incentives for better risk
                                          management.

    Broad brush structure.             More risk sensitivity.
Market Risk Charge

 – Rigorous backtesting
Qualitative criteria for using internal model
Independent risk control unit
Backtesting
Involvement of senior management and board

Operational Risk Charge


Basic Indicator Approach
Standardised approach
 – Activities divided into 8 business lines
 – Multiply by respective beta factors and sum
Advanced Measurement approach
 – Sound track record in control and management of
   operational risk
Capital standards for banks and securities houses

    Capital standards for banks and securities houses
     have different purposes.
    Bank capital is designed to maintain the safety and
     soundness of banks.
    So capital standards for banks are calculated on a
     going concern basis.
    In contrast, capital standards for securities firms are
     calculated on liquidation basis.
    During the recent sub prime crisis, central banks have
     provided lines of liquidity to investment banks; so
     the Fed’s hold over the investment banks is likely to
     tighten.

                                                           12
Convergence of Regulation

     The    regulation   of non    bank   financial
      intermediaries is now converging with that of
      commercial banks.
     The lines of business are getting increasingly
      blurred, thanks to the 1999 repeal of the Glass
      Steagall Act and financial innovation.
     Goldman and Morgan Stanley have become
      bank holding companies
     JP Morgan Chase and Citi are already universal
      banks.

Emerging challenges


Cyclicality bias
Originate to distribute
Quantum of capital
