Governments often attempt to reduce inflation by controlling the supply of money. Consequently, organizations that control how much money is issued in an economy play a major role in how the economy performs, in terms of prices, output and employment levels, and economic growth. In the United States, that organization is the nation’s central bank, the Federal Reserve System. The system’s name comes from the fact that the Federal Reserve has the legal authority to make banks hold some of their deposits as reserves, which means the banks cannot lend out those deposits. These reserve funds are held in the Federal Reserve Bank. The Federal Reserve also acts as the banker for the federal government, but the government does not own the Federal Reserve. It is actually owned by the nation’s banks, which by law must join the Federal Reserve System and observe its regulations.
There are 12 regional Federal Reserve banks. These banks are not commercial banks. They do not accept savings deposits from or provide loans to individuals or businesses. Instead, the Federal Reserve functions as a central bank for other banks and for the federal government. In that role the Federal Reserve System performs several important functions in the national economy. First, the branches of the Federal Reserve distribute paper currency in their regions. Dollar bills are actually Federal Reserve notes. You can look at a dollar bill of any denomination and see the number for the regional Federal Reserve Bank where the bill was originally issued. But of course the dollar is a national currency, so a bill issued by any regional Federal Reserve Bank is good anyplace in the country. The distribution of currency occurs as commercial banks convert some of their reserve balances at the Federal Reserve System into currency, and then provide that currency to bank depositors who decide to hold some of their money balances as currency rather than deposits in checking accounts. The U.S. Treasury prints new currency for the Federal Reserve System. The bills are introduced into circulation when commercial banks use their reserves to buy currency from the Federal Reserve Bank.
Second, the regional Federal Reserve banks transfer funds for checks that are deposited by a bank in one part of the country, but were written by someone who has a checking account with a bank in another part of the country. Millions of checks are processed this way every business day. Third, the regional Federal Reserve Banks collect and analyze data on the economic performance of their regions, and provide that information and their analysis of it to the national Federal Reserve System. Each of the 12 regions served by the Federal Reserve banks has its own economic characteristics. Some of these regional economies are concerned more with agricultural issues than others; some with different types of manufacturing and industries; some with international trade; and some with financial markets and firms. After reviewing the reports from all different parts of the country, the national Federal Reserve System then adopts policies that have major effects on the entire U.S. economy.
By far the most important function of the Federal Reserve System is controlling the nation’s money supply and the overall availability of credit in the economy. If the Federal Reserve System wants to put more money in the economy, it does not ask the Treasury to print more dollar bills. Remember, much more money is held in checking and savings accounts than as currency, and it is through those deposit accounts that the Federal Reserve System most directly controls the money supply. The Federal Reserve affects deposit accounts in one of three ways.
First, it can allow banks to hold a smaller percentage of their deposits as reserves at the Federal Reserve System. A lower reserve requirement allows banks to make more loans and earn more money from the interest paid on those loans. Banks making more loans increase the money supply. Conversely, a higher reserve requirement reduces the amount of loans banks can make, which reduces or tightens the money supply.
The second way the Federal Reserve System can put more money into the economy is by lowering the rate it charges banks when they borrow money from the Federal Reserve System. This particular interest rate is known as the discount rate. When the discount rate goes down, it is more likely that banks will borrow money from the Federal Reserve System, to cover their reserve requirements and support more loans to borrowers. Once again, those loans will increase the nation’s money supply. Therefore, a decrease in the discount rate can increase the money supply, while an increase in the discount rate can decrease the money supply.
