The Office of the Comptroller of the Currency (OCC), the Board of Governors of the Federal Reserve System (Board), and the Federal Deposit Insurance Corporation (FDIC) (collectively, the Agencies) are amending their respective risk-based capital standards for market risk applicable to certain banks and bank holding companies with significant trading activities. The amendment eliminates the requirement that when an institution measures specific risk using its internal model, the total capital charge for specific risk must equal at least 50 percent of the standard specific risk capital charge. The amendment implements a revision to the Basle Accord that permits such treatment for an institution whose internal model adequately measures specific risk. The rule will reduce regulatory burden for institutions with qualifying internal models because they will no longer be required to calculate a standard specific risk capital charge.
