PS1/26 – Implementation of Basel 3.1: Final rules
Policy statement 1/26
PS1/26 represents the UK Prudential Regulation Authority's final implementation framework for the Basel 3.1 international banking standards, effective 1 January 2027 (with market risk internal models delayed to 1 January 2028). This policy statement establishes mandatory capital, credit risk, operational risk, and market risk requirements for UK-regulated banks, building societies, and investment firms, addressing post-financial crisis shortcomings in risk-weighted asset (RWA) calculations and capital adequacy frameworks.
The Prudential Regulation Authority (PRA) has published the final rules for the implementation of Basel 3.1 standards in the UK, with an effective date of January 1, 2027. The rules aim to enhance the resilience of banks and improve the stability of the financial system. Firms must review and update their policies and procedures to ensure compliance with the new requirements.
