The Board of Governors of the Federal Reserve System (Board) is adopting a final rule that amends the Board's liquidity coverage ratio rule and modified liquidity coverage ratio rule (together, LCR rule) to include certain U.S. municipal securities as high-quality liquid assets (HQLA). This final rule includes as level 2B liquid assets under the LCR rule general obligation securities of a public sector entity (i.e., securities backed by the full faith and credit of a U.S. state or municipality) that meet similar criteria as corporate debt securities that are included as level 2B liquid assets, subject to limitations that are intended to address the structure of the U.S. municipal securities market. The final rule applies to all Board- regulated institutions that are subject to the LCR rule: Bank holding companies, certain savings and loan holding companies, and state member banks that, in each case, have $250 billion or more in total consolidated assets or $10 billion or more in on-balance sheet foreign exposure; state member banks with $10 billion or more in total consolidated assets that are consolidated subsidiaries of bank holding companies described in the first instance; nonbank financial companies designated by the Financial Stability Oversight Council for Board supervision to which the Board has applied the LCR rule by separate rule or order; and bank holding companies and certain savings and loan holding companies, in each case with $50 billion or more in total consolidated assets, but that do not meet the thresholds described in the first through third instances, which are subject to the Board's modified liquidity coverage ratio rule.
