Basel 4

Welcome to the KPMG Global Insights page for Basel 4. Here you will find regulatory updates and analysis, links to KPMG solutions and details of key contacts across KPMG’s international network.

Although final rules have been agreed in most jurisdictions, including the EU and UK (Basel 3.1), the US position remains uncertain. The original Basel III Endgame proposals were expected to undergo material updates, and it is possible that under the new Administration they will be substantially watered down or scrapped altogether. The PRA’s decision to delay UK implementation by a further year to 1 January 2027, pending further clarity from the US, has reignited challenges from the EU around the level playing field. Mandated EBA reviews in 2028 may result in further EU-specific amendments.

Banks face a significant book of work and multiple challenges as they stand up or refresh their Basel programmes - ranging from gap analysis assessments against existing rules, to identifying and making necessary changes to operating models, to building new RWA calculators, sourcing data and submitting model applications. KPMG member firms are actively supporting banks across all aspects of their Basel implementations, leveraging our global expertise – reach out to your local contacts below to discuss.
