Reserve Requirements


Reserve requirements are the amount of funds that a depository institution must hold in reserve against specified deposit liabilities. Within limits specified by law, the Board of Governors has sole authority over changes in reserve requirements. Depository institutions must hold reserves in the form of vault cash or deposits with Federal Reserve Banks.

The dollar amount of a depository institution's reserve requirement is determined by applying the reserve ratios specified in the Federal Reserve Board's Regulation D to an institution's reservable liabilities (see table of reserve requirements). Reservable liabilities consist of net transaction accounts, nonpersonal time deposits, and eurocurrency liabilities. Since December 27, 1990, nonpersonal time deposits and eurocurrency liabilities have had a reserve ratio of zero.

The reserve ratio on net transactions accounts depends on the amount of net transactions accounts at the depository institution. The Garn-St Germain Act of 1982 exempted the first $2 million of reservable liabilities from reserve requirements. This "exemption amount" is adjusted each year according to a formula specified by the act. The amount of net transaction accounts subject to a reserve requirement ratio of 3 percent was set under the Monetary Control Act of 1980 at $25 million. This "low-reserve tranche" is also adjusted each year (see table of low-reserve tranche amounts and exemption amounts since 1982). Net transaction accounts in excess of the low-reserve tranche are currently reservable at 10 percent.

Since October 2008, the Federal Reserve Banks have paid interest on required reserve balances and excess balances.

For more history on the changes in reserve requirement ratios and the indexation of the exemption and low-reserve tranche, see the annual review table. Additional details on reserve requirements can be found in the Reserve Maintenance Manual and in the article (119 KB PDF) in the Federal Reserve Bulletin, the appendix of which has tables of historical reserve ratios.

Note. Required reserves must be held in the form of vault cash and, if vault cash is insufficient, also in the form of a deposit maintained with a Federal Reserve Bank. An institution that is a member of the Federal Reserve System must hold that deposit directly with a Reserve Bank; an institution that is not a member of the System can maintain that deposit directly with a Reserve Bank or with another institution in a pass-through relationship. Reserve requirements are imposed on commercial banks, savings banks, savings and loan associations, credit unions, U.S. branches and agencies of foreign banks, Edge corporations, and agreement corporations.

1. Total transaction accounts consists of demand deposits, automatic transfer service (ATS) accounts, NOW accounts, share draft accounts, telephone or preauthorized transfer accounts, ineligible bankers acceptances, and obligations issued by affiliates maturing in seven days or less. Net transaction accounts are total transaction accounts less amounts due from other depository institutions and less cash items in the process of collection. For a more detailed description of these deposit types, see Form FR 2900 at http://www.federalreserve.gov/apps/reportforms/default.aspx Return to table

2. The amount of net transaction accounts subject to a reserve requirement ratio of zero percent (the "exemption amount") is adjusted each year by statute. The exemption amount is adjusted upward by 80 percent of the previous year's (June 30 to June 30) rate of increase in total reservable liabilities at all depository institutions. No adjustment is made in the event of a decrease in such liabilities. Return to table

3. The amount of net transaction accounts subject to a reserve requirement ratio of 3 percent is the "low-reserve tranche." By statute, the upper limit of the low-reserve tranche is adjusted each year by 80 percent of the previous year's (June 30 to June 30) rate of increase or decrease in net transaction accounts held by all depository institutions.

The reserve requirement exemption was also raised from $3.6 million to $3.8 million. The actions reduced required reserves by an estimated $699 million.
83. Effective November 12, 1992, the lag in counting vault cash toward required reserves was shortened from four weeks to two weeks for institutions reporting weekly on the FR2900, i.e. counting the average vault cash held during a reserve computation period toward required reserves in its corresponding reserve maintenance period.
82. Effective September 3, 1992, the carryover allowance for reserve balances, for institutions reporting weekly and quarterly on the FR2900, was doubled to the larger of $50,000 or 4 percent of required reserves plus required clearing balances less the institution's required clearing balance penalty-free band.

This action reduced required reserves approximately $1,065 million.
30. Effective December 12, 1974, the reserve requirement against all time deposits with an original maturity of six months or longer was reduced from 5 percent to 3 percent; the reserve requirement against all time deposits with an original maturity of less than six months was increased from 5 percent to 6 percent; and the reserve requirement against net demand deposits over $400 million was reduced from 18 percent to 17-1/2 percent.

27. Effective October 4, 1973, the marginal reserve requirement against certain time deposits was increased from 8 percent to 11 percent. This action increased required reserves approximately $465 million.
26. Effective July 19, 1973, the reserve requirement against all net demand deposits, except the first $2 million was increased 1/2 percentage point. This action increased required reserves approximately $760 million.
25. Effective July 12, 1973, reserve requirements were imposed against finance bills. This action increased required reserves approximately $90 million.
24. Effective June 21, 1973, the Board amended its Regulation D to establish a marginal reserve requirement of 8 percent against certain time deposits and to subject to the 8 percent reserve requirement certain deposits exempt from the rate limitations of the Board's Regulation Q. In addition, reserves against certain foreign branch deposits were reduced from 10 percent to 8 percent. These changes had little effect on required reserves.
23. Effective November 9, 1972, Regulations D and J were revised to (1) adopt a system of reserve requirements against demand deposits of all member banks based on the amount of such deposits held by a member bank, and (2) to require banks--member and nonmember--to pay cash items presented by a Federal Reserve Bank on the day of presentation in funds available to the Reserve Bank on that day. These changes reduced required reserves approximately $2.5 billion, effective November 9; $1.0 billion, effective November 16; and increased required reserves $300 million, effective November 23.
22. Effective January 7, 1971, the reserve requirement on certain foreign borrowings, primarily Eurodollars, by member banks, and the sale of assets to their foreign branches was raised from 10 percent to 20 percent. This action had little effect on required reserves.
