Under the proposed rule, bank holding companies with more than $700 billion in consolidated total assets or $10 trillion in assets under custody (covered BHCs) would be required to maintain a tier 1 capital leverage buffer of at least 2 percent above the minimum supplementary leverage ratio requirement of 3 percent, for a total of 5 percent. The proposed rule would be effective on January 1, 2018. Comments must be submitted within 60 days of publication in the Federal Register. Joint Release. Proposed Rule.
