The non-internal model method for capitalising counterparty credit risk exposures : consultative document ; issued for comment by 27 September 2013

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.
