The Federal Reserve System, often called simply the Fed, has 12 regional Federal Reserve Banks. Each bank is responsible for a Federal Reserve District. Most large commercial banks belong to the system. They use the Reserve Bank in their district much as people use a bank in their community. Each member bank must keep a certain sum of money either as currency in its vaults or as deposits at its Reserve Bank. This sum is a percentage of the member bank’s own deposits and is called a reserve requirement. The reserve requirement is set by the Federal Reserve. A bank may withdraw any excess deposits at the Reserve Bank to get currency when needed. It may also borrow from the Reserve Bank. The Federal Reserve has the authority to set reserve requirements for all deposit-taking institutions.

   The Federal Reserve influences the economy largely by affecting interest rates. It works to control these rates in several ways. It may raise or lower reserve requirements. Or the Federal Reserve may raise or lower the discount rate, which is the interest rate commercial banks pay to borrow from Reserve Banks. Raising the reserve requirement or the discount rate lowers the ability of banks to make loans and thus tends to raise interest rates and shrink the money supply. Lowering the reserve requirement or the discount rate tends to have the opposite effect on interest rates and the money supply.

   However, the Federal Reserve controls interest rates chiefly by buying and selling government securities. These activities are called open-market operations. If the Federal Reserve wants to reduce interest rates, it makes an open-market purchase. It buys government securities from banks and other businesses and from individuals. The Federal Reserve pays for the securities with a check. The sellers now have more money than before, and the amount of money in the economy has increased, banks have more money to lend than before, and they lower their interest rates. When the sellers deposit the checks at their bank, interest rates may fall—and the supply of money may increase-further. To reduce interest rates, the Federal Reserve sells securities in an open-market sale. The money supply tends to shrink as a result.

   Efforts to stabilize the economy by focusing on either interest rates or on the money supply may be ineffective because changes in these factors do not affect the economy immediately. If the effect of a change is long delayed, it may strike the economy at the wrong time. For example, the Federal Reserve might have decided to increase the money supply in the hope of reducing joblessness within six months. However, the drop in unemployment might have happened at a time when unemployment had already begun to fall for other reasons. Instead of reducing joblessness, the Federal Reserve’s action might then have only fueled inflation.

   The Federal Reserve’s task is also difficult because it is likely to increase unemployment when it tries to reduce inflation, and vice versa. If the Federal Reserve fights inflations by increasing interest rates, and thus reducing the money supply, employers may cut back on production and more workers will lose their jobs. If the Federal Reserve reduces interest rates to create more jobs, price increases may follow. In such cases, the Federal Reserve may have difficulty deciding what to do. Some economist believes that the best way to fight inflation and unemployment is by a gradual, continuous increase in the money supply. 


 
Much trade takes place between nations. For example, Americans buy French cheese and Japanese automobiles, and the French and Japanese buy American airplanes and blue jeans. Most imported good must be paid for in the currency of the selling country. An automobile dealer in the United States who buys Japanese cars gets yen by buying them from a bank at the current exchange rate. An exchange rate is the price of one nation’s currency expressed in terms of another country’s currency. If the exchange rate were 100 yen to the U.S. dollar, the American would have to buy $12,000 in yen to pay for a Japanese auto that cost 1.2 million yen.

   Exchange rates are determined in foreign exchange markets. The rates vary from day to day in relation to international demand for various currencies. If Americans buy more Japanese products, for example, the U.S. demand for yen increases and the yen rises in price against the dollar. This system is known as floating exchange rates or flexible exchange rates. But the United States and many other countries do not allow the rate for their currency to float freely. Each of these countries has holdings of foreign currency. If the exchange rate falls too far, the government will use some of its foreign holdings to buy enough of its own currency to stabilize the exchange rate.

 
The balance of payments is the difference between a nation’s receipts of foreign currency and its expenditures of foreign currency. A nation’s balance of payments affects its exchange rate. The world price of a country’s currency tends to rise if the countries receipts exceed its expenditures. This condition is called a balance-of-payments surplus. A nation’s currency will tend to decline on world markets if more money flows out of the country than comes in. this condition is called a balance-of-payments deficit.

   The primary influences on the balance of payments are income levels and rates of inflation. Suppose income levels rise more quickly abroad than in the United States. People in other countries then will increase their imports of American goods. The United States will export more than it imports, creating a balance-of-payments surplus and causing the world price of U.S. dollars to increase. If inflation causes prices to rise more quickly in the United States than aboard, foreign goods become cheaper for Americans to buy and they import more. This situation creates a balance-of-payments deficit and causes the U.S dollar to drop in price.

   International reserves. A large number of countries use official holdings of foreign currency to stabilize exchange rates and to pay international debts. These holdings are called international reserves. The U.S. dollar plays a special role in international reserves, partly because the United States is one of the world’s leading trading nations. Many countries keep nearly all their international reserves in U.S. dollars, and most countries are willing to accept payment in dollars. To some extent, the U.S. dollar thus functions as an international medium of exchange.

  The International Monetary Fund (IMF) is an organization that works to improve financial dealings between countries. The International Monetary Fund has introduced a type of international reserves called Special Drawing Rights (SDR’s). Member countries of the IMF can use these reserves to settle accounts among themselves. Unlike other reserves, SDR’s exist only as entries on the account books of the IMF. Some economists think SDR’s eventually will become widely used as an international medium of exchange.

 
Money market fund is a mutual fund that invests only in short-term securities. The term money market refers to the buying and selling of such securities. Money market funds are also known as liquid asset funds, cash funds, or money funds.

   Many institutions need to borrow money for short periods—a year or less. Such institutions include the federal government, banks and other financial forms, and corporations. The securities that these institutions sell in the money market yield returns closely tied to current interest rates. Common types of money market securities include Treasury bills and certificates of deposit.

   Like all other mutual funds, money market funds pool the money of many investors and pay them interest. The interest rate paid varies, depending on market conditions. However, it usually exceeds the rate small investors get in savings accounts that have limits on interest rates.

   The United States government does not insure the money in money market funds. However, money market funds invest mainly in lo-risk securities and are considered safe.

   Money market funds developed during the early 1970’s.Their low initial investment, high yields, and safety led to spectacular growth. However, that trend ended in 1982, when the federal government allowed savings institutions to offer federally insured accounts that provided yields similar to those of money market funds. Today, there are more than 450 money market funds in the United States. Their net assets total more than $260 billion.

Money orders resemble checks and thus provide a safe way to send money through the mail. A purchaser fills out a money order and mails it t the person he or she has indicated. The person receiving the order may cash it at a bank or post office.

   U.S. postal money orders may be either domestic or international. A domestic money order may be sent anywhere within the United States. Domestic orders also may be sent to Antigua And Barbuda, the Bahamas, Barbados, Belize, the British Virgin Islands, Canada, Dominica, Grenada, Jamaica, Montserrat, St. Kitts and Nevis, St. Lucia, St Vincent and the Grenadinesand Trinidad and Tobago. An international money order may be sent to any of the approximately 75 countries that honor them.

   The highest face value of any single domestic or international money order is $700. No individual may purchase postal money orders exceeding $10,000 in face value on any day.

   A postal money order may be cashed at any time after the date of issue. Postal money orders may be endorsed only once. The United States Postal Service refunds the value of its money orders if they are lost or stolen in the mail.     

   Canadian postal money orders cannot have a face value of more than $999.99 in Canadian dollars. However, an unlimited number of money orders may be purchased.
