As final rules emerge and are finalized, 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.
