The currency exchange rates are determined by the market. The currency is free-floating and as a result its rate is not fixed as was done before. The rates in the market are determined by the extent of demand and supply of the currency in the market. As a result, its rates constantly changed and fluctuated. Earlier the currency rate was based on the fixed exchange rate when a currency was fixed with reference to another by the government who could change or devalue this rate as and when needed. Between World War II and 1966 the Western European countries fixed the exchange rates to the dollar. The market based exchange was adopted later.
Whenever there is a change in the value of one currency, the exchange rate with another currency will change. When the demand for a currency increases and is more than the supply, it becomes more valuable. But when the demand is lower than the supply, the value of the currency declines. The increase in demand for a currency can be due to many reasons. There could be an increase in the transaction demand for the currency. Or there could be an increase in the speculative demand for the currency. The transaction demand is related to the level of business activity of the country, the employment levels and the gross domestic product (GDP). When more people are employed, the more will be the spending on goods and services.

The change in the demand for currency as a result of business activity is adjusted by the central banks by adjusting the available money supply. It is difficult for the central banks to adjust to the demand for money from speculation. They try to do this by adjusting the interest rates. With higher interest rates, there is an increase in the purchase of that currency. The demand for the currency increases. Currency speculation is considered to undermine the economy of a country as large currency speculators can unduly influence the exchange rates.
