Basel III applicable in almost all member jurisdictions by 2027

Member jurisdictions of the Basel Committee on Banking Supervision made further progress in implementing the Basel III reforms, according to the Committee’s latest progress update, published today. 

The update and monitoring dashboard set out the jurisdictional adoption status of the Basel III standards as of end-September 2026 and show where the standards are already implemented by banks. They cover the final elements of Basel III published by the Committee in December 2017 and the finalised minimum capital requirements for market risk of January 2019. The implementation date for these reforms was 1 January 2023, as announced by the Governors and Heads of Supervision (GHOS) – the Basel Committee’s oversight body – in March 2020.

As of 30 September 2026, three quarter of the member jurisdictions have published their rules adopting the final Basel III, ie all standards with an implementation date of 1 January 2023. The revised credit risk and operational risk standards, as well as the output floor, are already effective in around 85% of the member jurisdictions. Looking ahead, almost all member jurisdictions have publicly announced that banks must apply Basel III by April 2027 or earlier.

The monitoring dashboard provides the implementation history of Basel standards by member jurisdictions, including the publication and implementation dates of their domestic regulations.
