Foreign exchange markets are markets in which national currencies are bought and sold with other national currencies. In a foreign exchange market U.S. dollars may purchase British pounds, German marks, French francs, Japanese yen, etc.

Prices of foreign currency are expressed as exchange rates, the rate at which one currency can be converted into another currency. On 12 March 1997 it took $1.59 to purchase a British pound in foreign exchange markets, or, alternatively 0.6256 British pounds could purchase one U.S. dollar. Exchange rates are reported daily in large metropolitan newspapers and financial papers such as the Wall Street Journal.

Foreign exchange markets are as old as coinage itself. In the ancient world religious temples were a popular site of foreign exchange markets because the sacredness of the grounds acted to safeguard treasuries of coin. The modern term bank evolved from the moneychangers’ “bench” of the Middle Ages. Today modern communication and computers have made possible a worldwide integrated foreign exchange market where trades are conducted electronically 24 hours a day during the business week. The big players in the foreign exchange markets are the large commercial banks with foreign branches.

Under the current international monetary system, foreign exchange markets are highly competitive and exchange rates can change daily. (Between 1946 and 1971 the world was on a fixed exchange rate system, and exchange rates were pegged at certain levels by governments.) A supply of U.S. dollars is created in foreign exchange markets when Americans buy goods, or make investments, in foreign countries where dollars are not accepted. A demand for U.S. dollars is created in foreign exchange markets when the rest of the world wants to buy American goods, or make American investments, which require payment in dollars. Exchange rates fluctuate to balance supply and demand, clearing the market for U.S. dollars as foreign exchange. Markets for other currencies emerge in a similar fashion.

Exchange rates can exert strong influences on domestic economies. If the market value of the dollar appreciates relative to the Japanese yen—meaning it takes fewer dollars to purchase a yen—Japanese goods become cheaper to American consumers, increasing the importation of Japanese goods and reducing demand for domestic goods in competition with Japanese goods. If the market value of the dollar depreciates relative to the Japanese yen—meaning it takes more dollars to purchase a yen—Japanese goods become more expensive to American consumers, diminishing the importation of Japanese goods and making domestic goods more competitive. In summary, a depreciation of the dollar increases the demand for American-made goods, and an appreciation of the dollar decreases the demand for American-made goods.

Foreign exchange rates are quoted in spot rates and forward rates. The spot rate is the rate at which foreign currency can be purchased for delivery within two business days. A forward rate is the rate at which a foreign currency can be purchased for delivery after a length of time, such as 90 days. A forward market enables an American importer to strike a deal to import French goods and purchase French francs to pay for the goods when they arrive at some date in the future, protecting the importer from fluctuations in exchange that could make the goods much more expensive than expected.

Unless the world adopts a common currency, foreign exchange markets will remain a vital part of the international trade framework, the connecting link that allows trade between countries with different currencies. On 1 January 1999 Europe launched the euro, a European currency that will eventually replace German marks, French francs, Swiss francs, and other European currencies, and will abolish the need for foreign exchange markets to establish rates for the convertibility of one European currency into another. If the world follows the path of economic integration followed in Europe, then a world currency could become a reality some day.

On the upside a world currency would remove the risk and uncertainty of exchange rate fluctuations that can disturb the flow of international trade, and promote trade between the regions of the world. On the downside a world currency would preclude the use of localized monetary policies to help specific areas. Currently, the Japanese economy is stagnant and the Bank of Japan is free to expand the Japanese money supply to stimulate the economy.

If the world was on a worldwide currency system, and Japan was the only country suffering stagnation, world monetary authorities could not expand the money supply worldwide just to help Japan—and besides, increasing the money supply worldwide might not help Japan anyway.

1. The Post Audit aspect capital budgeting
An important aspect of the capital budgeting process is the post-audit, which involves (1) comparing actual results with those predicted by the project’s sponsors and (2) explaining why any differences occurred. For example, many firms require that the operating divisions send a monthly report for the first six months after a project goes into operation, and a quarterly report thereafter, until the project’s results are up to expectations. From then on, reports on the operation are reviewed on...

2. Commodity Monetary Standard
Under a commodity monetary standard, a medium of exchange and unit of account is either a commodity or a claim to a commodity and the commodity is a good that would have value even if it were not used for money. Put differently, the commodity has an intrinsic value, in contrast to the paper money of an inconvertible paper standard that has value only by government fiat and is called fiat money for that reason. In the purest form of commodity money, the commodity itself may change hands. History furnishes numerous examples...

3. Identifying the Relevant Cash Flows ~ Project Cash Flow versus Accounting Income
The most important, but also the most difficult, step in capital budgeting is estimating projects’ cash flows—the investment outlays and the annual net cash flows after a project goes into operation. Many variables are involved, and many individuals and departments participate in the process. For example, the forecasts of unit sales and sales prices are normally made by the marketing group, based on their knowledge of price elasticity, advertising effects, the state of the economy, competitors’ reaction...

4. What are Bills of Exchange
Bills of exchange developed during the Middle Ages as a means of transferring funds and making payments over long distances without physically moving bulky quantities of precious metals. In the hands of thirteenth-century Italian merchants, bankers, and foreign exchange dealers, the bill of exchange evolved into a powerful financial tool, accommodating short-term credit transactions as well as facilitating foreign exchange transactions. The invention of the bill of exchange greatly facilitated foreign trade. The mechanics...

5. What is the Interest Rate
The interest rate can be regarded as the cost of money, expressed as a percentage. If the annual interest rate is 10 percent, an individual borrowing $100 for a year pays $10 interest. Decimalized currency systems substantially facilitated the calculation of interest. This is one reason countries rapidly adopted decimalized currency systems during the nineteenth century. Theoretically, interest rates adjust to a level at which the interest earned on $100 invested in financial assets (for example, corporate bonds) equals t...

7. What is The Balance of Payments
The balance of payments for a country summarizes all the international transactions that involve either an outflow or an inflow of money. It is composed of three major elements: (1) the current account, (2) the capital account, and (3) the official reserves transactions account. The official reserves transactions account reflects the official transactions between central banks that must occur when the combined balance of the current and capital accounts is in either the deficit or surplus column. Transactions that lead to...

8. Short Introduction in Forced Savings
Forced savings refers to the use of money creation and inflation to divert resources into the production and acquisition of capital goods. A government that prints up money, as opposed to levying taxes or selling bonds, to pay for the construction of a hydroelectric generation facility is pursuing a policy of forced savings. Less-developed countries, particularly in Latin America, turned to forced savings policies in the post–World War II era as a means of financing economic development. At least some of the inflation in ...

9. What is the Value of Money
The value of money has to do with the purchasing power of a unit of money. One approach to the measurement of money value is to look at its precious metal equivalent. Under a gold standard, a dollar should be worth approximately a dollar’s worth of gold. Under a gold coin standard, the value of a dollar could drop below a dollar if the government reduces the gold content of its coinage relative to its face value. Under such circumstances it might be appropriate to say that a dollar is worth only 75 cents or 50 cents, based ...

10. What is the Velocity of Money
The velocity of money is the average number of times per year that a unit of currency (e.g., U.S. dollar, Japanese yen, German mark, etc.) is spent on goods and services. From a theoretical perspective a percentage change in the velocity of money can have the same impact on prices or other economic variables as an equivalent percentage change in the money supply. Sir William Petty (1623–1687) may have been the first writer on economics to describe the velocity of money. He advanced the plausible view that the velocity...
