An exchange rate is the price of one nation’s currency in terms of another nation’s currency. Since the value of money in any nation depends on its purchasing power, the demand for money is based on its ability to maintain the value and on the level of economic activity. Thus, exchange rates respond to force of demand and supply. In addition, under the absence of government intervention, exchange rates are dependent on relative inflation rates, interest rates, and GDP growth rates. Let us take a closer look at these factors to see how the exchange rate can be affected.
