Feedback on Basel III Prudential Roadmap: advanced approaches, systemic importance, the NSFR and the leverage ratio
Feedback on Basel III Prudential Roadmap: advanced approaches, systemic importance, the NSFR and the leverage ratio1 Executive summary
Introduction
In March 2024, we published our consultation on the Basel III prudential roadmap. This included a timeline for detailed consultations, including capital requirements, operational and credit risk, liquidity and leverage requirements and prudential reporting. These will take place ahead of implementation in H2 2027, with flexibility for banks to transition from H2 2026. Our approach would:
- be based on the UK’s implementation
- be proportionate, flexible and simple
- address competitive disadvantages
As part of that work, in August 2025, we published a consultation paper on:
- advanced approaches to credit risk and the output floor
- systemic importance and the systemic buffer
- the Net Stable Funding Ratio (NSFR)
- the leverage ratio
This paper summarises responses received and our feedback.
The consultation also included a revised roadmap timeline, reflecting the UK’s announcement of a delay to its implement Basel III until 1 January 2027, recent PRA consultations and feedback received from banks. As a result, the transition window will begin on 1 January 2027, and an additional consultation will be issued in Q4 2025 to address areas linked to the PRA’s changes.
