The "Closing the Enhanced Prudential Standards Loophole Act" seeks to amend the Financial Stability Act of 2010, specifically targeting a regulatory gap concerning certain financial institutions. Its core purpose is to apply the existing enhanced supervision and prudential standards to large banks that operate without a bank holding company. Currently, these stringent standards primarily govern bank holding companies. This legislation mandates that banks lacking a bank holding company structure will be subject to the same regulatory provisions as a bank holding company possessing an equivalent amount of total consolidated assets, thereby promoting consistent oversight across the financial sector.
