The standardised methodology, described in chapters CA-9 through CA-13, uses a "building-block" approach in which the specific risk and the general market risk arising from debt and equity positions are calculated separately. The focus of most internal models is a bank's general market risk exposure, typically leaving specific risk (i.e., exposures to specific issuers of debt securities and equities) to be measured largely through separate credit risk measurement systems. Banks applying models are subject to separate capital charges for the specific risk not captured by their models, which shall be calculated by the standardised methodology. The capital charge for banks which are modelling specific risk is set out in section CA-14.10.
