The Prudential Regulation Authority (PRA) has issued final policy to retire the refined methodology to Pillar 2A, and has updated Supervisory Statement 31/15 on the Internal Capital Adequacy Assessment Process (ICAAP) and the Supervisory Review and Evaluation Process (SREP). The changes apply to all PRA-regulated banks, building societies, designated investment firms, and PRA-approved or PRA-designated holding companies, including Small Domestic Deposit Takers (SDDTs) and firms considering SDDT status. The final policy is unchanged from the near-final version published in PS18/25, following feedback to Consultation Paper 9/24, which received 12 responses. Implementation is aligned with the PRA’s Basel 3.1 implementation date. The refined methodology will cease to apply from 1 January 2027 for all firms, including SDDTs, as they will be subject to the Basel 3.1 standardised approach to credit risk from that date.
