CA-9.6 CA-9.6 Derivatives
CA-9.6.1
Banks which propose to use internal models to measure the interest rate risk inherent in
derivatives will seek the prior written approval of the CBB for applying those models. The use of internal models to measure market risk, and the CBB's rules applicable to them, are discussed in detail in chapter CA-14.Apr 08CA-9.6.2
Where a bank, with the prior written approval of the CBB, uses an interest rate sensitivity model, the output of that model is used, by the duration method, to calculate the general market risk as described in Section CA-9.5.

Where a bank does not propose to use models, it must use the techniques described in the following Paragraphs, for measuring the market risk on interest rate
derivatives . The measurement system should include all interest ratederivatives and off-balance-sheet instruments in the trading book which react to changes in interest rates (e.g. forward rate agreements, other forward contracts, bond futures, interest rate and cross-currencyswaps , options and forward foreign exchange contracts). Where a bank has obtained the approval of the CBB for the use of non-interest ratederivatives models, the embedded interest rateexposures should be incorporated in the standardised measurement framework described in Sections CA-9.7 to CA-9.9.Amended: January 2012

Derivative positions will attract specific risk only when they are based on an underlying instrument or
security . For instance, where the underlyingexposure is an interest rateexposure , as in aswap based upon inter-bank rates, there will be no specific risk, but onlycounterparty risk. A similar treatment applies to FRAs, forward foreign exchange contracts and interest rate futures. However, for aswap based on a bond yield, or a futures contract based on a debtsecurity or an index representing a basket of debtsecurities , the credit risk of the issuer of the underlying bond will generate a specific risk capital requirement. Future cash flows derived from positions inderivatives will generatecounterparty risk requirements related to thecounterparty in the trade, in addition to position risk requirements (specific and general market risk) related to the underlyingsecurity .Apr 08
