At the end of step (c), there will be either asset or liability positions, to which a capital charge of 15% will apply. The CBB recognises that there are differences in volatility between different commodities, but has, nevertheless, decided that one uniform capital charge for open positions in all commodities shall apply in the interest of simplicity of the measurement, and given the fact that banks normally run rather small open positions in commodities. Banks will be required to submit in writing, details of their commodities business in order to capture the market risk on this business and to enable the CBB to evaluate whether the models approach should be adopted by the bank.
