Meaning And Significance of Foreign Exchange


  • Forex is a commonly used abbreviation for “Foreign Exchange,” and it is typically used to describe trading in the foreign exchange market by investors and speculators.
  • The foreign exchange market (forex, FX, or currency market) is a global decentralized market for the trading of currencies. This includes all aspects of buying, selling and exchanging currencies at current or determined prices.
  • In terms of volume of trading, it is by far the largest market in the world.


  • Exchange ratebetween two currencies is the rate at which one currency will be exchanged for another. It is also regarded as the value of one country’s currency in terms of another currency.
  • Exchange rates are determined in theforeign exchange market, which is open to a wide range of different types of buyers and sellers where currency trading is continuous: 24 hours a day.
  • In the retail currency exchange market, a different buying rate and selling rate will be quoted by money dealers. Most trades are to or from the local currency.


  • Daily turnover in the world’s currencies comes from two sources:
  • Foreign trade (5%). Companies buy and sell products in foreign countries, plus convert profits from foreign sales into domestic currency.
  • Speculation for profit (95%).
  • Most traders focus on the biggest, most liquid currency pairs. “The Majors” include US Dollar, Japanese Yen, Euro, British Pound, Swiss Franc, Canadian Dollar and Australian Dollar. In fact, more than 85% of daily forex trading happens in the major currency pairs.


  • Currencies trade on an open market, just like stocks, bonds, computers, cars, and many other goods and services. A currency’s value fluctuates as its supply and demand fluctuates, just like anything else.
  • An increase in supply or a decrease in demand for a currency can cause the value of that currency to fall.
  • A decrease in the supply or an increase in demand for a currency can cause the value of that currency to rise.
  • A big benefit to forex trading is that one can buy or sell any currency pair, at any time subject to available liquidity. So if one think the Eurozone is going to break apart, he can sell the euro and buy the dollar (sell EUR/USD). If he think the price of gold is going to go up, based on historical correlation patterns he can buy the Australian dollar and sell the U.S. dollar (buy AUD/USD).


  • National central banks play an important role in the foreign exchange markets. They try to control themoney supply, inflation, and/or interest rates and often have official or unofficial target rates for their currencies.
  • They can use their often substantial foreign exchange reserves to stabilize the market. Nevertheless, the effectiveness of central bank “stabilizing speculation” is doubtful because central banks do not go bankrupt if they make large losses, like other traders would, and there is no convincing evidence that they do make a profit trading.


  • Foreign exchange fixingis the daily monetary exchange rate fixed by the national bank of each country. The idea is that central banks use the fixing time and exchange rate to evaluate behaviour of their currency.
  • Fixing exchange rates reflects the real value of equilibrium in the market. Banks, dealers and traders use fixing rates as amarket trend indicator.
  • The mere expectation or rumour of a central bank foreign exchange intervention might be enough to stabilize a currency, but aggressive intervention might be used several times each year in countries with adirty float currency regime.
  • Central banks do not always achieve their objectives. The combined resources of the market can easily overwhelm any central bank.Several scenarios of this nature were seen in the 1992–93 European Exchange Rate Mechanism collapse, and in more recent times in Asia.
