The document specifies the reporting templates and calculation methodologies for market risk capital charges within the Revised Return of Capital Adequacy Ratio (Form MA(BS)3). It details the Standardized Trading Book (STM) approach for interest rate, equity, foreign exchange, commodity, and option exposures, including specific risk and general market risk components. The text provides tables for non-securitization and securitization exposures, outlining capital charge factors for various credit quality grades and residual maturities. It also defines the Internal Models Method (IMM) approach for calculating Value at Risk (VaR) and Stressed VaR, including back-testing exception requirements.

(2) During the transitional period (securitization) of 1 January 2012 to 31 December 2013, both dates inclusive, the applica ble market risk capital charge for specific risk (i.e. Item 1.17) for the interest rate exposures of a reporting institution is c alculated as the larger of the total market risk capital charge for the long positions or the total market risk capital charge for the short position s reported in the last column of Item 1.16. Upon the expiry of the transitional period (securitization), the applicable market risk capital charge for specific risk (i.e. Item 1.17) of the institution is calculated as the sum of the market risk capital charge for the gross (i.e. long + short) positions reported in the last column of Item 1.16.
