Resources and guidance relating to the overhaul of regulatory capital requirements proposed by US banking regulators.
In late July 2023, US banking regulators released proposals to significantly revise the risk-based regulatory capital requirements for certain midsize and larger US banking organizations and change how the capital surcharge is calculated for global, systemically important banking organizations. These proposals, colloquially referred to as “Basel III Endgame”, are critical, as the amount of capital a bank must maintain with respect to any particular loan, investment or activity is typically a significant factor in determining whether the relationship is profitable or even feasible.
Below, we include links to Mayer Brown’s Legal Updates, seminars and podcasts, and other useful materials to help you navigate these critical proposals.
