The Board is amending Regulation D, Reserve Requirements of Depository Institutions, to simplify the administration of reserve requirements. The final rule creates a common two-week maintenance period for all depository institutions, creates a penalty-free band around reserve balance requirements in place of carryover and routine penalty waivers, discontinues as-of adjustments related to deposit report revisions, replaces all other as-of adjustments with direct compensation, and eliminates the contractual clearing balance program. The amendments are designed to reduce the administrative and operational costs associated with reserve requirements for depository institutions, the Board, and Federal Reserve Banks.
