  1. Basel I, Basel II, and Solvency II Chapter XII

  2. The Reasons for Regulating Banks • The purpose is to ensure banks keep enough capital for the risks they take. • Governments would like to make the probability of a bank failing small. • Governments would like to create and maintain a stable economic system.

  3. Bank Regulation Pre-1988 • Prior to 1988, bank regulators tended to regulate bank capital by setting minimum levels for the ratio of capital to total assets. • The lack of consistency in several countries lead to a problem in which total assets were no longer a good indicator of the total risks taken.

  4. The 1988 BIS Accord • Supervisory authorities from several countries formed the Basel Committee on Banking Supervision. • This is also known as The Accord or Basel I recently.

  5. The Cooke Ratio • It considers both on-balance-sheet and off-balance-sheet items to calculate the bank’s total risk-weighted assets (amount). • It is a measure of the bank’s total credit exposure. • Each item on the on-balance-sheet item is assigned risk weight reflecting its credit risk.

  6. The Cooke Ratio

  7. The Cooke Ratio

  8. Example • The assets of a bank consist of $100 million of corporate loans, $10 million of OECD government bonds, and $50 million of residential mortgages. The total of risk-weighted assets is 1.0*100 + 0.0*10 + 0.5*50 = $125million

  9. The Cooke Ratio • Off-balance-sheet items are expressed as a credit equivalent amount. • Credit equivalent amount is the loan principal that is considered to have the same credit risk. • For non-derivatives the credit equivalent amount is calculated by applying a conversion factor to the principal amount of the instrument.

  10. The Cooke Ratio • For an over-the-counter derivative, such as an interest rate swap or a forward contract, the credit equivalent amount is calculated as max(V,0) + aL • where V is the current value of the derivative to the bank, a is an add-on factor, and L is the principal amount. • The bank’s exposure is max(V,0) and the add-on amount, aL, is an allowance for the possibility of future exposure increasing.

  11. The Cooke Ratio • The equation above is the current exposure. • If the counterpart defaults today and V is positive, the contract is an asset to the bank and the bank is liable to lose V. • However, if the counterpart defaults today and V is negative, the contract is an asset to the counterparty and there will be neither a gain nor a loss to the bank.

  12. The Cooke Ratio

  13. Example • A bank has entered into $100 million interest rate swap with a remaining life of four years. The current value of the swap is $2 million. In this case the add-on amount is 0.5% of the principal, so that the credit equivalent amount is $2 million plus $0.5 million, or $2.5 million.
