The Currency Exchange Market

The Currency Exchange Market

The currency exchange market is an inter-bank or inter-dealer market that was established in 1971 when floating exchange rates began to materialize. In addition, it is an Over-The-Counter market, meaning that transactions are conducted between any two counter parties that agree to trade via the telephone or electronic network. Trading is thus not centralized, as is the case with many stock markets (i.e., NYSE, ASE, CME) or as the case for currency futures and currency options, which trade on special exchanges. Dealers often "advertise" exchange rates using a distribution network, such as the one provided by Reuters or Bridge. Dealers then use the information obtained there (or directly) to "agree" to a rate and a trade.

The major dealing centers today are: London, with about 30% of the market, New York, with 20%, Tokyo, with 12%, Zurich, Frankfurt, Hong Kong and Singapore, with about 7% each, followed by Paris and Sydney with 3% each.

In terms of trading volume, the currency exchange market is the worlds largest market, with daily trading volumes in excess of $1.5 trillion US dollars. This is orders of magnitude larger than the bond or stock market. For example, the New York Stock Exchange has a daily trading volume of approximately $60 billion. Thus, the currency exchange market is by far the most liquid market in the world today. Because of the volume in trading, it is impossible for individuals or companies to affect the exchange rates. In fact, even central banks and governments find it increasingly difficult to affect the exchange rates of the most liquid currencies, such as the US dollar, Japanese Yen, Euro, Swiss Frank, Canadian Dollar or Australian Dollar.

The currency exchange market is a true 24-hour market, 5 days a week. There are dealers in every major time zone. Trading begins Monday morning in Sydney (which corresponds to 3pm EST, Sunday) and then daily moves around the globe through the various trading centers until closing Friday evening at 4:30pm EST in New York.

Today, over 85% of all currency exchange transactions involve a few major currencies: the US Dollar (USD), Japanese Yen (JPY), Euro (EUR), Swiss Frank (CHF), British Pound (GBP), Canadian Dollar (CAD), and Australian Dollar (AUD). In the currency exchange market, most of the currencies are traded only against the US Dollar. The term cross rate refers to an exchange rate between two non-dollar currencies. Trading between two non-dollar currencies usually occurs by first trading one against the US Dollar and then trading the US Dollar against the second non-dollar currency. Because of this, the spread in the exchange rate between two non-dollar currencies is often higher. (There are a few non-dollar currencies that are traded directly, such as GBP/EUR or EUR/CHF.) The following directly traded currency pairs make up the vast majority of the trading volume and are thus considered to be the most important ones: EUR/USD, USD/JPY, EUR/JPY, USD/CAD, EUR/GBP, GBP/USD, USD/CHF, AUD/USD, and AUD/JPY.
