The Basel Committee's consultative paper The non-internal model method for capitalising counterparty credit risk exposures outlines a proposal to improve the methodology for assessing the counterparty credit risk associated with derivative transactions. The proposal would, when finalised, replace the capital framework's existing methods - the Current Exposure Method and the Standardised Method. It improves on the risk sensitivity of the Current Exposure Method by differentiating between margined and unmargined trades. The proposed non-internal model method updates supervisory factors to reflect the level of volatilities observed over the recent stress period and provides a more meaningful recognition of netting benefits. At the same time, the proposed method is suitable for a wide variety of derivatives transactions, reduces the scope for discretion by banks and avoids undue complexity.
The Basel Committee will conduct a quantitative impact study in order to inform the final formulation of the non-internal model method and to assess the difference in exposure and overall capital requirements under this proposal as compared to other measures of counterparty credit risk under the Basel framework. In addition to replacing the Current Exposure Method and the Standardised Method, the non-internal model method may also be used with respect to the leverage ratio, large exposures, and exposures to central counterparties (CCPs).
