Three quarters of Basel Committee members have adopted final Basel III rules
Almost all of the 27 member jurisdictions have said their banks must apply Basel III by April 2027 or earlier, the Committee said in a progress update.
AI illustrationThree quarters of the 27 member jurisdictions of the Basel Committee on Banking Supervision have published regulations that implement the full set of Basel III standards, according to the Committee's latest progress update.
Almost all member jurisdictions have publicly announced that banks must apply Basel III by April 2027 or earlier, the update said.
The update and a monitoring dashboard show how far each jurisdiction had adopted the standards as of the end of September 2026, and where banks already apply them. They cover the final elements of Basel III that the Committee published in December 2017 and the finalised minimum capital requirements for market risk from January 2019. The implementation date for these reforms was 1 January 2023, as announced in March 2020 by the Governors and Heads of Supervision, the Committee's oversight body.
The revised standards for credit risk and operational risk, together with the output floor, are already in force in around 85% of member jurisdictions, according to the update.
At their meeting on 9 March 2026, the Governors and Heads of Supervision welcomed the progress and reaffirmed that they expect all member jurisdictions to implement the framework fully and consistently as soon as possible. The update said that a series of shocks to financial markets over the past few years, and recent market developments, have shown the importance of a prudent global regulatory framework and a level playing field.
The oversight body tasked the Committee with continuing to monitor and assess whether Basel III is implemented fully and consistently, and the Committee said it will continue to do so closely.
