Welcome to the KPMG Global Insights page for Basel reforms. Here you will find regulatory updates and analysis, links to KPMG solutions and details of key contacts across KPMG’s international network. For our latest views, see the “Moving the dial” series.

As final rules emerge and are finalised, it is time for banks to focus firmly on the implementation of the Basel 3 final reforms, variously referred to as Basel 4, Basel 3.1 or Basel 3 Endgame.

Implementation was delayed due to the pandemic, but regulators around the globe are now pushing ahead with their plans. The Basel Committee on Banking Supervision has been clear that a ‘full and consistent’ implementation of the framework should be targeted ‘as soon as possible’. However, timelines are not consistent across all jurisdictions and banks will also need to consider local variations in final requirements.
