The Board is amending Regulation D (Reserve Requirements of Depository Institutions) and Regulation I (Issue and Cancellation of Federal Reserve Bank Capital Stock) to make two substantive changes and other clarifying amendments. The first substantive amendment conforms Regulation D to Section 603 of the Financial Services Regulatory Relief Act of 2006 (Pub. L. 109-351, Oct. 13, 2006) by authorizing member banks of the Federal Reserve System to enter into pass-through arrangements. Previously, member banks were statutorily prohibited from passing required reserve balances through a correspondent institution. The second substantive amendment eliminates the provision in Regulation D's definition of "savings deposit" that limits certain kinds of transfers from savings deposits to not more than three per month. As a result, all transfers and withdrawals from a savings deposit that are subject to a monthly limit will be subject to the same limit of not more than six per month. The remaining clarifying amendments reorganize the provisions relating to deposit reporting and the calculation and maintenance of required reserves, clarify the definition of "vault cash," and make other minor editorial changes.
