Article 193 Principles for recognising the effect of credit risk mitigation techniques

No exposure in respect of which an institution obtains credit risk mitigation shall produce a higher risk-weighted exposure amount or expected loss amount than an otherwise identical exposure in respect of which an institution has no credit risk mitigation.

Where the risk-weighted exposure amount already takes account of credit protection under Chapter 2 or Chapter 3, as applicable, institutions shall not take into account that credit protection in the calculations under this Chapter.

Where the provisions in Sections 2 and 3 are met, institutions may amend the calculation of risk-weighted exposure amounts under the Standardised Approach and the calculation of risk-weighted exposure amounts and expected loss amounts under the IRB Approach in accordance with the provisions of Sections 4, 5 and 6.

Institutions shall treat cash, securities or commodities purchased, borrowed or received under a repurchase transaction or securities or commodities lending or borrowing transaction as collateral.

Where an institution calculating risk-weighted exposure amounts under the Standardised Approach has more than one form of credit risk mitigation covering a single exposure it shall do both of the following:

subdivide the exposure into parts covered by each type of credit risk mitigation tool;

calculate the risk-weighted exposure amount for each part obtained in point (a) separately in accordance with the provisions of Chapter 2 and this Chapter.

When an institution calculating risk-weighted exposure amounts under the Standardised Approach covers a single exposure with credit protection provided by a single protection provider and that protection has differing maturities, it shall do both of the following:

subdivide the exposure into parts covered by each credit risk mitigation tool;

calculate the risk-weighted exposure amount for each part obtained in point (a) separately in accordance with the provisions of Chapter 2 and this Chapter.

Collateral that satisfies all eligibility requirements set out in this Chapter can be recognised even for exposures associated with undrawn facilities, where drawing under the facility is conditional on the prior or simultaneous purchase or reception of collateral to the extent of the institution’s interest in the collateral once the facility is drawn, such that the institution does not have any interest in the collateral to the extent the facility is not drawn.
