In the s, when the Federal Reserve discovered that open-market operations also created reserves, changing nonborrowed reserves offered a more effective way to offset undesired changes in borrowing by member banks. In the s, the Federal Reserve sought to control what are called free reserves, or excess reserves minus member bank borrowing. The Fed has interpreted a rise in interest rates as tighter monetary policy and a fall as easier monetary policy. But interest rates are an imperfect indicator of monetary policy.
If easy monetary policy is expected to cause inflation, lenders demand a higher interest rate to compensate for this inflation, and borrowers are willing to pay a higher rate because inflation reduces the value of the dollars they repay.
Thus, an increase in expected inflation increases interest rates. Between and , for example, U. Similarly, if tight monetary policy is expected to reduce inflation, interest rates could fall. From to , when Paul Volcker was chairman of the Federal Reserve, the Fed tried to control nonborrowed reserves to achieve its monetary target.
The procedure produced large swings in both money growth and interest rates. Forcing nonborrowed reserves to decline when above target led borrowed reserves to rise because the Federal Reserve allowed banks access to the discount window when they sought this alternative source of reserves.
Since then, the Federal Reserve has specified a narrow range for the federal funds rate, the interest rate on overnight loans from one bank to another, as the instrument to achieve its objectives.
Although the Fed does not directly transact in the Fed funds market, when the Federal Reserve specifies a higher Fed funds rate, it makes this higher rate stick by reducing the reserves it provides the entire financial system.
When it specifies a lower Fed funds rate, it makes this stick by providing increased reserves. The Fed funds market rate deviates minimally from the target rate. If the deviation is greater, that is a signal to the Fed that the reserves it has provided are not consistent with the funds rate it has announced. It will increase or reduce the reserves depending on the deviation.
The Federal Reserve adopted an implicit target for projected future inflation. Its success in meeting its target has gained it credibility. This increase in the ratio of money supply to GNP shows an increase in the amount of money as a fraction of their income that people wanted to hold.
From to , nominal GNP tended to grow at a higher rate than the growth of the money supply, an indication that the public reduced its money balances relative to income. Until , money balances grew relative to income; since then they have declined relative to income.
Economists explain these movements by changes in price expectations, as well as by changes in interest rates that make money holding more or less expensive. If prices are expected to fall, the inducement to hold money balances rises since money will buy more if the expectations are realized; similarly, if interest rates fall, the cost of holding money balances rather than spending or investing them declines. If prices are expected to rise or interest rates rise, holding money rather than spending or investing it becomes more costly.
Since a sustained decline of the money supply has occurred during only three business cycle contractions, each of which was severe as judged by the decline in output and rise in unemployment : —, —, and — The severity of the economic decline in each of these cyclical downturns, it is widely accepted, was a consequence of the reduction in the quantity of money, particularly so for the downturn that began in , when the quantity of money fell by an unprecedented one-third.
There have been no sustained declines in the quantity of money in the past six decades. The United States has experienced three major price inflations since , and each has been preceded and accompanied by a corresponding increase in the rate of growth of the money supply: —, —, and — An acceleration of money growth in excess of real output growth has invariably produced inflation—in these episodes and in many earlier examples in the United States and elsewhere in the world.

Key Takeaways Central banks use several methods, called monetary policy, to increase or decrease the amount of money in the economy. The Fed can increase the money supply by lowering the reserve requirements for banks, which allows them to lend more money. Conversely, by raising the banks' reserve requirements, the Fed can decrease the size of the money supply.
The Fed can also alter short-term interest rates by lowering or raising the discount rate that banks pay on short-term loans from the Fed. Compare Accounts. The offers that appear in this table are from partnerships from which Investopedia receives compensation.

Federal Reserve What happens if the Federal Reserve lowers the reserve ratio? At the micro-level, a large supply of free and easy money means more spending by people and by businesses.
Individuals have an easier time getting personal loans, car loans, or home mortgages ; companies find it easier to secure financing, too. At the macroeconomic level, the amount of money circulating in an economy affects things like gross domestic product, overall growth, interest rates, and unemployment rates. The central banks tend to control the quantity of money in circulation to achieve economic objectives and affect monetary policy.
Once upon a time, nations pegged their currencies to a gold standard , which limited how much they could produce. But that ended by the midth century, so now, central banks can increase the amount of money in circulation by simply printing it.
They can print as much money as they want, though there are consequences for doing so. Since this can cause inflation, simply printing more money isn't the first choice of central banks.
One of the basic methods used by all central banks to control the quantity of money in an economy is the reserve requirement. As a rule, central banks mandate depository institutions that is, commercial banks to keep a certain amount of funds in reserve stored in vaults or at the central bank against the amount of deposits in their clients' accounts. Thus, a certain amount of money is always kept back and never circulates. When the central bank wants more money circulating into the economy, it can reduce the reserve requirement.
This means the bank can lend out more money. If it wants to reduce the amount of money in the economy, it can increase the reserve requirement. This means that banks have less money to lend out and will thus be pickier about issuing loans. Central banks periodically adjust the reserve ratios they impose on banks.
In most cases, a central bank cannot directly set interest rates for loans such as mortgages, auto loans, or personal loans. However, the central bank does have certain tools to push interest rates towards desired levels. For example, the central bank holds the key to the policy rate—the rate at which commercial banks get to borrow from the central bank in the United States, this is called the federal discount rate. When banks get to borrow from the central bank at a lower rate, they pass these savings on by reducing the cost of loans to their customers.
Lower interest rates tend to increase borrowing, and this means the quantity of money in circulation increases. Central banks affect the quantity of money in circulation by buying or selling government securities through the process known as open market operations OMO.
When a central bank is looking to increase the quantity of money in circulation, it purchases government securities from commercial banks and institutions. This frees up bank assets: They now have more cash to loan.
Central banks do this sort of spending a part of an expansionary or easing monetary policy, which brings down the interest rate in the economy. It is not just that most money is in the form of bank accounts. The banking system can literally create money through the process of making loans.
Start with a hypothetical bank called Singleton Bank. The T-account balance sheet for Singleton Bank, when it holds all of the deposits in its vaults, is shown in Figure 1.
At this stage, Singleton Bank is simply storing money for depositors; it is not using these deposits to make loans, so it cannot pay its depositors interest either. Figure 1. Instead of becoming just a storage place for deposits, Singleton Bank can become a financial intermediary between savers and borrowers. Figure 2. The bank records this loan by making an entry on the balance sheet to indicate that a loan has been made.
This loan is an asset, because it will generate interest income for the bank. Hank deposits the loan in his regular checking account with First National. Figure 3. Making loans that are deposited into a demand deposit account increases the M1 money supply. Remember the definition of M1 includes checkable demand deposits, which can be easily used as a medium of exchange to buy goods and services.
The bottom line is that a bank must hold enough money to meet its reserve requirement; the rest the bank loans out, and those loans, when deposited, add to the money supply.
