As stated in Section CA-13.1, conventional bank licensees which have a significant level of options trading activities, or have complex options trading strategies, must use more sophisticated methods for measuring and monitoring the options risks. Conventional bank licensees with the appropriate capability will be permitted, with the prior approval of the CBB, to base the market risk capital charge for options portfolios and associated hedging positions on scenario matrix analysis. Before giving its approval, the CBB will closely review the accuracy of the analysis that is constructed. Furthermore, like in the case of internal models, the conventional bank licensees' use of scenario analysis as part of the standardised methodology will also be subject to external validation, and to those of the qualitative standards listed in Chapter CA-14 which are appropriate given the nature of the business.
