Effects on money supply

The reserve requirement can affect monetary policy, because the higher the reserve requirement is set, the less money banks will have to loan out, leading to lower money creation, and maintaining the purchasing power of the currency previously in use. The effect is exponential, because money that is loaned out can be re-deposited; a portion of that money may again be re-loaned, and so on. The effect on the monetary supply is governed by the following formula:


Money Supply

There are several ways to define "money," but standard measures usually include currency in circulation and demand deposits .Money supply data are recorded and published, usually...

the reserve requirement (the percent of deposits that banks are not allowed to lend)

However, in the United States (and other countries except Brazil, China, India, Russia), the reserve requirements are generally not frequently altered to affect monetary policy because of the exponential effect and the large time lag between the implementation of the change and the corresponding effects on inflation.

). The only deposit category currently subject to reserve requirements are net transactions accounts, mainly checking accounts. The total amount of all net transaction accounts held in USA depository institutions, plus US currency held by the nonbank public, is called M1.

A depository institution can satisfy its reserve requirements by holding either vault cash or reserve deposits. An institution that is a member of the Federal Reserve System must hold its reserve deposits at a Federal Reserve Bank. Nonmember institutions can elect to hold their reserve deposits at a member institution on a pass-through basis.

A depository institution's reserve requirements vary by the dollar amount of net transaction accounts held at that institution. Effective December 30, 2010, institutions with net transactions accounts:
  • Of less than $10.7 million have no minimum reserve requirement;
  • Between $10.7 million and $58.8 million must have a liquidity ratio of 3%;
  • Exceeding $58.8 million must have a liquidity ratio of 10%.

The numerical amounts stated above are recalculated annually according to a statutory formula.

Effective December 27, 1990, a liquidity ratio of zero has applied to CDs

s, owned by entities other than households, and the Eurocurrency liabilities of depository institutions. Deposits owned by foreign corporations or governments are currently not subject to reserve requirements.

When an institution fails to satisfy its reserve requirements, it can make up its deficiency with reserves borrowed either from a Federal Reserve Bank, or from an institution holding reserves in excess of reserve requirements. Such loans are typically due in 24 hours or less.

An institution's overnight reserves, averaged over some maintenance period, must equal or exceed its average required reserves, calculated over the same maintenance period. If this calculation is satisfied, there is no requirement that reserves be held at any point in time. Hence reserve requirements play only a limited role in money creation in the USA.
