CRE41 Securitisation: standardised approach (paras. 41.1-41.22) (effective as of 15 December 2019)
This chapter describes how to calculate capital requirements for securitisation exposures using a standardised approach (SEC-SA).
Version effective as of 15 Dec 2019
First version in the format of the consolidated framework.
Standardised approach (SEC-SA)
41.1 To calculate capital requirements for a securitisation exposure to a standardised approach (SA) pool using the securitisation standardised approach (SEC-SA), a bank would use a supervisory formula and the following bank-supplied inputs: the SA capital charge had the underlying exposures not been securitised (KSA); the ratio of delinquent underlying exposures to total underlying exposures in the securitisation pool (W); the tranche attachment point (A); and the tranche detachment point (D). The inputs A and D are defined in CRE44.14 and CRE44.15 respectively. Where the only difference between exposures to a transaction is related to maturity, A and D will be the same. KSA and W are defined in CRE41.2 to CRE41.4 and CRE41.6.
