This consultation is segmented across 13 chapters. PRA has invited responses to 51 questions across Chapters 2 to 9 which are due by 31 March 2023.
These new rules would become effective by 1 January 2025 subject to certain transitional provisions as outlined below.
- Output floor – 5 year transitional period beginning 1 Jan 2025
- SA and IRB firms for the implementation of the revised treatment of equity exposures in the credit risk SA – 5 year transitional period starting 1 Jan 2025
- 5-year transitional period only for the legacy trades that would be exempt from CVA RWAs prior to the application of the new CVA requirements. Banks have the option to irreversibly apply the new CVA requirements to these trades instead.
- Banks allowed to apply the SA-CCR reduced alpha multiplier to trades with certain counterparties. Banks are needed to maintain additional Pillar 1 capital equal to the reduction in capital requirements on the proposed implementation date for the legacy trades. The additional capital requirement for the legacy trades would reduce linearly over five years.
PRA will not entertain any review at the end of the transitional period to in order to reduce the speed of convergence with the international standards including avoiding implementation uncertainty for banks.
