On Balance Risk Charges

Off Balance Risk Charges  The Basle Accord computes a credit exposure through credit conversion factors.  Instruments that substitute for a loan  Transaction related contingencies  Short term self liquidating traded related liabilities  Commitments with maturity greater than a year  Other derivatives such as swaps, forwards and options on currency, interest rates, equity and commodity products are given special treatment

The New Basle Accord  The Basle Accord has been successful in raising banking capital (tier 1 ratio)  Issues with the 1988 accord regulatory arbitrage (lending pattern to in the direction of more credit risk)  inadequate differentiation between credit risks  Securitization  Non recognition of credit risk mitigation techniques  Non recognition of diversification of credit risk

Operational Risk Charges (ORC)  Basle Committee expects that ORC will represent about 20% of the Total Risk Charge on average  3 Approaches proposed  the Basic Indicator Approach  the Standardized Approach  the Internal Measurement Approach  the most sophisticated, based on internal bank data, the bank then provides:  the probability of loss event (PE)  the loss given that event (LGE)  the expected loss (EL)

 The measurement of ORC is the least advanced component of the Basle Accord ...  mucch work to be done on the calibration of models (if any ...) Daniel HERLEMONT
