WHAT IS A CENTRAL BANK?

Just as a prudent driver keeps an eye on the road and a hand on the wheel, every country's central bank watches economic data carefully and adjusts the money supply in an effort to keep the economy headed in the right direction.

Instead of taking deposits and making loans as normal banks do, a central bank controls the economy by increasing or decreasing the country's supply of money. Cranking up the printing presses is not the only way for a central bank to increase the economy's supply of money. In fact, in most modern economies printed notes and coins are only a small percentage—often less than 10 percent—of the money supply. Central banks usually print only enough currency to satisfy the everyday needs of businesses and consumers.

Since most "money" is actually nothing more than a savings or checking account at a local bank, the most effective way for a central bank to control the economy is to increase or decrease bank lending and bank deposits. When banks have money to lend to their custom­ers, the economy grows. When the banks are forced to cut back lending, the economy slows.

Once a customer deposits money in a local bank, it becomes available for further lending. A hundred dollars deposited at a bank in London, for example, doesn't lie idle for long. After setting aside a small amount of each deposit as a "reserve," the bank can lend out the remainder, further increasing the money supply—without any new currency being printed. When these loans are redeposited in banks, more money becomes available for new loans, increasing the money supply even more. A bank's supply of money for lending is limited only by its deposits and its reserve requirements, which are determined by the central bank.

Central banks often use these reserve requirements to control the money supply. When a bank is required to keep a certain amount of its funds on reserve with the central bank—10 percent of deposits for example—it is unable to lend these funds back to customers. When a central bank decides to increase the money supply, it can reduce this reserve requirement, allowing banks to use more of their funds to lend to businesses and consumers. This increases the money supply quickly because of a multiplier effect: as the new loans enter the economy, deposits increase—and banks have even more money to lend, which generates further deposits providing more money for further loans.

Another way of controlling the money supply is to raise or lower interest rates. When a central bank decides that the economy is grow­ing too slowly—or not growing at all—it can reduce the interest rate it charges on the loans to the country's banks. When banks are allowed to get cheaper money at the central bank, they can make cheaper loans to businesses and consumers, providing an important stimulus to eco­nomic growth. Alternatively, if the economy shows signs of growing too quickly, a central bank can increase the interest rate on its loans to banks, putting the brakes on economic growth.

Perhaps the most dramatic way of increasing or decreasing the money supply is through open market operations, where a central bank buys or sells large amounts of securities, such as government treasury bonds, in the open market. By buying a large block of bonds, from a bank or a securities house for example, the central bank pumps money into the economy because it uses funds that previously were not part of the money supply. The money used to buy the bonds then becomes available for banks to lend out to consumers and businesses.

A central bank, unlike other players in the economy, does not have to secure funding from any other source. It can simply print more money or use its virtually unlimited credit with banks in the system. Once a central bank's payment enters the economy, it becomes part of the money supply, providing fuel for businesses and consumers to increase their economic activities. Likewise, when a central bank sells bonds in the open market, the payments from banks and securities houses disappear into the black hole of the central bank's vault, com­pletely removed from the economy at large.

An error in judgment at the central bank has grave consequences for everyone in the economy. If a central bank allows the economy to expand too rapidly by keeping too much money in circulation, it may cause inflation. If it slows down the economy by removing too much money from circulation, an economic recession could result, bringing unemployment and reduced production. A central serves as a watchdog to supervise the banking system, in most cases acting independently of its government to provide a stabilizing influence on the country's economy.

The activities and responsibilities of central banks vary widely from country to country. For example, Britain's Bank of England is responsible for printing the money as well as supervising the banking system and coordinating monetary policy. In the United States, the duties of a central bank are divided among different agencies: the U.S. Treasury borrows the government's money through Treasury bond and note issues, while the Federal Reserve Board is put in charge of mone­tary policy and oversees the printing of money at the Bureau of Print­ing and Engraving.

The French central bank, the Banque de France, prints and issues the money, but the French treasury makes the decisions regarding monetary policy and bank supervision. In Germany, the central bank, called the Bundesbank, is noted for its active policy of strict monetary control, limiting money supply growth in order to control inflation at all costs.

The Bank of Japan, like many of the world's central banks, acts as banker to the government. This activity is a major source of revenue for the bank since fees are charged for issuing the government's checks
