The Basel Committee's latest progress update tracks how its 27 member jurisdictions are implementing the post-2017 Basel III reforms, originally due to take effect in 2023. This briefing covers the published status as of end-September 2026 and the compliance deadline most members have now set.
- Three quarters of the Basel Committee's 27 member jurisdictions have published rules adopting the full Basel III standards as of 30 September 2026.
- The revised credit risk and operational risk standards, along with the output floor, are already effective in around 85% of member jurisdictions.
- Almost all member jurisdictions have publicly announced that banks must apply Basel III by April 2027 or earlier.
- The standards cover the final Basel III elements published in December 2017 and the finalised minimum capital requirements for market risk from January 2019, with an original implementation date of 1 January 2023 set by the GHOS in March 2020.
- The GHOS met on 9 March 2026, welcomed implementation progress and reaffirmed its expectation of full and consistent implementation, tasking the Committee with continued monitoring.
