The Board of Governors of the Federal Reserve System voted to publish final rules (June 7th, 2012) on market risk capital. For Banks with a high proportion of trading assets and liabilities, the final market risk capital rule prescribes methods for calculating the market risk capital requirement (Basel 2.5) for FX and commodities positions and certain trading assets and liabilities. Those rules have been delayed in the US as regulators sought to adjust their rules to comply with the Dodd-frank Act Section 939A requiring from the Agencies to remove all references to and requirements of reliance on credit ratings from their regulations and replace them with alternative standards of creditworthiness.
