1.A Bank must calculate a capital charge for interest rate risk, options risk and equity positions in the trading book. Equity exposure, foreign exchange risk and commodity risk and options risk must be calculated on the Bank’s entire positions. Options risk must also be calculated for options on foreign exchange or commodities positions not belonging to the trading book. In addition, a Bank must take into account other relevant market risk exposures, including but not limited to interest rate risk in the Banking book, as part of the Internal Capital Adequacy Assessment Process to ensure that it holds adequate capital against all market risks.
