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 rate derivatives 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-currency swaps, options and forward foreign exchange contracts). Where a bank has obtained the approval of the Central Bank for the use of non-interest rate derivatives models, the embedded interest rate exposures should be incorporated in the standardised measurement framework described in Sections CA-4.7 to CA-4.9.
