What Is Foreign Exchange Market: ?

To buy foreign goods or services, or to invest in other countries, companies and individuals may need to first buy the currency of the country with which they are doing business. Generally, exporters prefer to be paid in their country’s currency or in U.S. dollars, which are accepted all over the world.

When Canadians buy oil from Saudi Arabia they may pay in U.S. dollars and not in Canadian dollars or Saudi riyals, even though the United States is not involved in the transaction.

The foreign exchange market, or the "FX" market, is where the buying and selling of different currencies takes place. The price of one currency in terms of another is called an exchange rate.

The market itself is actually a worldwide network of traders, connected by telephone lines and computer screens—there is no central headquarters. There are three main centers of trading, which handle the majority of all FX transactions—United Kingdom, United States, and Japan.

Transactions in Singapore, Switzerland, Hong Kong, Germany, France and Australia account for most of the remaining transactions in the market. Trading goes on 24 hours a day: at 8 a.m. the exchange market is first opening in London, while the trading day is ending in Singapore and Hong Kong. At 1 p.m. in London, the New York market opens for business and later in the afternoon the traders in San Francisco can also conduct business. As the market closes in San Francisco, the Singapore and Hong Kong markets are starting their day.

The FX market is fast paced, volatile and enormous—it is the largest market in the world. In 2001 on average, an estimated $1,210 billion was traded each day—roughly equivalent to every person in the world trading $195 each day.

Theory and Econometric Evidence

The flotation of exchange rates in the early 1970s saw a significant increase in the importance of foreign exchange markets and in the interest shown in them. Apart from the consequent institutional changes, this period also witnessed a revolution in macroeconomic analysis and finance theory based on the concept of rational expectations. This book provides an integrated approach to recent developments in the understanding of foreign exchange markets. It begins by charting the institutional background and looks at the recent history of movements in some of the major exchange rates. The theoretical sections focus on the economic and finance theory of the asset market approach, the macroeconomic models developed from this approach, and on interest rate parity theory. The empirical chapters draw on the authors’ own research from a high quality set of exchange rate and interest rate data. The statistical properties of exchange rates are analysed; the relationship between spot and forward rates is examined; and the modelling and impact of new information on the forward and spot relationship is considered. The final chapter is devoted to the estimation and testing of exchange rate models.
