Reserve requirement

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The reserve requirement (or cash reserve ratio) is a central bank regulation that sets the minimum fraction of customer deposits and notes that each commercial bank must hold as reserves (rather than lend out). These required reserves are normally in the form of cash stored physically in a bank vault (vault cash) or deposits made with a central bank.

The required reserve ratio is sometimes used as a tool in monetary policy, influencing the country's borrowing and interest rates by changing the amount of funds available for banks to make loans with.[1] Western central banks rarely alter the reserve requirements because it would cause immediate liquidity problems for banks with low excess reserves; they generally prefer to use open market operations (buying and selling government-issued bonds) to implement their monetary policy. The People's Bank of China uses changes in reserve requirements as an inflation-fighting tool,[2] and raised the reserve requirement ten times in 2007 and eleven times since the beginning of 2010. As of 2006 the required reserve ratio in the United States was 10% on transaction deposits and zero on time deposits and all other deposits.

An institution that holds reserves in excess of the required amount is said to hold excess reserves.

Effects on money supply [edit]

The reserve requirement can be used as an instrument of monetary policy, because the higher the reserve requirement is set, the less funds banks will have to loan out, leading to lower money creation and perhaps ultimately to higher purchasing power of the money previously in use. The effect is multiplied, because money obtained as loan proceeds can be re-deposited; a portion of those deposits may again be loaned out, and so on. The effect on the money supply is governed by the following formulas:

M1=Mb*mm \, : definitional relationship between monetary base Mb (bank reserves plus currency held by the non-bank public) and the narrowly defined money supply, M1,
mm=(1+c)/(c+R) \, : derived formula for the money multiplier mm, the factor by which lending and re-lending leads M1 to be a multiple of the monetary base:

where notationally,

c = the currency ratio: the ratio of the public's holdings of currency (undeposited cash) to the public's holdings of demand deposits; and
R = the total reserve ratio (the ratio of legally required plus non-required reserve holdings of banks to demand deposit liabilities of banks).

However, in the United States (and other countries except Brazil, China, India, Russia), the reserve requirements are generally not frequently altered to implement monetary policy because of the short-term disruptive effect on financial markets.

Jaromir Benes and Michael Kumhof of the IMF Research Department, report that: the “deposit multiplier“ of the undergraduate economics textbook, where monetary aggregates are created at the initiative of the central bank, through an initial injection of high-powered money into the banking system that gets multiplied through bank lending, turns the actual operation of the monetary transmission mechanism on its head.

At all times, when banks ask for reserves, the central bank obliges. Reserves therefore impose no constraint. The deposit multiplier is simply, in the words of Kydland andPrescott (1990), a myth. And because of this, private banks are almost fully in control of the money creation process. [3]

Required reserves [edit]

United States [edit]

In the United States, a reserve requirement (or liquidity ratio) is a minimum value, set by the Board of Governors of the Federal Reserve System, of the ratio of required reserves to some category of deposits held at depository institutions (e.g., commercial bank including US branch of a foreign bank, savings and loan association, savings bank, credit union). The only deposit categories 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.[4]

A depository institution's reserve requirements vary by the dollar amount of net transaction accounts held at that institution. Effective December 29, 2011, institutions with net transactions accounts:

  • Of less than $12.4 million have no minimum reserve requirement;
  • Between $12.4 million and $79.5 million must have a liquidity ratio of 3%;
  • Exceeding $79.5 million must have a liquidity ratio of 10%.[4]

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, savings deposits, and time deposits, 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.[4]

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.

United Kingdom [edit]

The Bank of England holds to a voluntary reserve ratio system, with no minimum reserve requirement set. In theory this means that banks could retain zero reserves, effectively allowing an infinite amount of credit money creation. However, the average cash reserve ratio across the entire United Kingdom banking system is higher, with a 3.1% average as of 1998.

Other countries [edit]

Other countries have required reserve ratios (or RRRs) that are statutorily enforced (sourced from Lecture 8, Slide 4: Central Banking and the Money Supply, by Dr. Pinar Yesin, University of Zurich, based on 2003 survey of CBC participants at the Study Center Gerzensee[5]):
