How does reserve requirement work

But changing the requirement is expensive for banks. For that reason, central banks don't want to adjust the requirement every time they shift monetary policy. Instead, they have many other tools that have the same effect as changing the reserve requirement. If the fed funds rate is high, it costs more for banks to lend to each other overnight. That has the same effect as raising the reserve requirement. Conversely, when the Fed wants to loosen monetary policy and increase liquidity, it lowers the fed funds rate target.

That makes lending fed funds cheaper. It has the same effect as lowering the reserve requirement. Here's the current fed funds rate. The Federal Reserve can't mandate that banks follow its targeted rate. The Fed buys securities, usually Treasury notes, from member banks when it wants the fed funds rate to fall. The Fed adds credit to the bank's reserve in exchange for the security.

Since the bank wishes to put this extra reserve to work, it will try to lend it to other banks. Banks cut their interest rates to do so. The Fed will sell securities to banks when it wants to increase the fed funds rate. Banks with fewer fed funds to lend can raise the fed funds rate. That how open market operations work. If a bank can't borrow from other banks, it can borrow from the Fed itself.

It also stigmatizes the bank. Other banks assume no other bank is willing to lend to it. They assume the bank has bad loans on its books or some other risk. As the fed funds rate rises, these four interest rates also rise:. During the financial crisis of , the Fed lowered the fed funds rate to zero.

Interest rates were as low as they could be. Still, banks were reluctant to lend. Reserve requirements are imposed on "depository institutions," defined as commercial banks, savings banks, savings and loan associations, credit unions, U.

Return to table. The following list covers regulatory changes in reserve requirements and indexation of the low reserve tranche and the reserve requirement exemption beginning December 1, , and their effects on required reserves.

Effective for the reserve maintenance period beginning March 26, , the 10 percent required reserve ratio against net transaction deposits above the low reserve tranche level was reduced to 0 percent, the 3 percent required reserve ratio against net transaction deposits in the low reserve tranche was reduced to 0 percent. Effective with the reserve maintenance period beginning July 30, , the required reserve system was shifted from CRR to new lagged reserve requirements LRR with reserve computation periods for weekly reporters starting thirty days before the corresponding reserve maintenance periods.

Under the new LRR regime, the lag in counting vault cash toward required reserves was lengthened from sixteen days to thirty days for institutions reporting weekly on the FR In other words, the average vault cash held during a reserve computation period would be applied toward required reserves in its corresponding reserve maintenance period. Effective November 12, , the lag in counting vault cash toward required reserves was shortened from four weeks to two weeks for institutions reporting weekly on the FR, i.

Effective April 2, , the 12 percent required reserve ratio against net transaction deposits above the low reserve tranche level was reduced to 10 percent. Effective with reserve maintenance period beginning January 17, , the 3 percent reserve requirement on nontransaction liabilities was reduced to zero for FR quarterly reporters.

Effective April 24, , money market deposit accounts MMDA , which had previously been subject to full reserve requirements, were made subject to the transitional phase-in program of the Monetary Control Act. In addition, the order of application of the exemption applied to reservable liabilities was changed.

Effective February 2, , Regulation D was amended as follows for institutions reporting weekly on the FR 1 change the reserve computation and maintenance periods from weekly to biweekly, with the former ending on Monday and the latter ending on Wednesday; 2 compute required reserves against net transaction deposits based on average deposits over the computation period ending two days before the end of the maintenance period; 3 compute required reserves against nontransaction deposits based on average deposits over a computation period ending 17 days before the beginning of the maintenance period; and 4 count the average vault cash held during a reserve computation period ending 17 days before the beginning of the reserve maintenance period toward required reserves.

Effective July 24, , the 5 percent marginal reserve requirement on managed liabilities and the 2 percent supplementary reserve requirement against large time deposits were removed. Effective May 29, , the marginal reserve requirement was reduced from 10 percent to 5 percent and the base upon which the marginal reserve requirement was calculated was raised.

Effective March 12, , the 8 percent marginal reserve requirement was raised to 10 percent. Banks and other depository institutions savings institutions, credit unions, and foreign banking entities are required to hold a portion of their deposits as reserves.

Depository institutions may hold reserves either as vault cash or as deposits with Federal Reserve Banks. Purpose and Functions describes how a change in the reserve requirement ratio affects bank credit and the money stock.

As those funds are lent, they create additional deposits in the banking system. The increase in deposits affects the money stock, because it is measured in several ways that primarily include various categories of deposits and currency in the hands of the public. Thus, even a small change in the reserve requirement ratio may have a relatively large effect on reserve requirements and the money stock.

There are several reasons why reserve requirements are not frequently changed, the most important of which is that open market operations provide a much more precise tool for implementing monetary policy.
