Modifications to the Capital Plan Rule and Stress Capital Buffer Requirement — 2026-10-02 [2026-20246]

Board of Governors of the Federal Reserve System (Board). The Board is adopting a final rule to amend the calculation of the Board's stress capital buffer requirement applicable to certain large bank holding companies, savings and loan holding companies, U.S. intermediate holding companies of foreign banking organizations, and nonbank financial companies supervised by the Board to reduce the volatility of the stress capital buffer requirement. The final rule uses the average of the maximum common equity tier 1 capital ratio declines projected in each of the Board's prior two annual supervisory stress tests to inform a firm's stress capital buffer requirement. The final rule also extends the annual effective date of the stress capital buffer requirement by one quarter, to January 1, to provide additional time for firms to comply with the requirement.
