The scenario approach and the internal models approach are generally regarded as more satisfactory for managing and measuring options risk, as they assess risk over a range of outcomes rather than focusing on the point estimate of the 'Greek' risk parameters as in the delta-plus approach. The more significant the level and/or complexity of the bank's options trading activities, the more the bank will be expected to use a sophisticated approach to the measurement of options risks. The CBB will monitor the banks' options trading activities, and the adequacy of the risk measurement framework adopted.
