Following the financial crisis, the passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) and the implementation of Basel III significantly changed the regulatory landscape in the U.S. This note discusses how the use of such fixed nominal thresholds impacts the extent of enhanced prudential supervision. Section 1 presents the various thresholds that are in place as of May 15, 2018. Section 2 analyzes the effect of these thresholds on the number and total assets of the affected banks, and examines whether the thresholds have caused any bunching of banks. Section 3 discusses possible changes that may help address some of these effects.
