The market determines the currency exchange rates. As currency is free-floating, its exchange rate fluctuates. The exchange rate is not fixed as used to earlier. The demand and supply in the market determines the exchange rate in the currency market. The rates keep changing and varying. Earlier currency had a fixed exchange rate with reference to another currency and this was done by the government who could devalue or change the rate as needed. For example, since World War II to 1966 the Western European countries had dollar as the reference to which the exchange rates were fixed. But this was changed subsequently to the exchange rate based on the market.
The exchange rate of a currency with respect to another changes when the value of one currency changes. The value of a currency increases when its demand increases more than the supply. The value declines when the demand for the currency declines with reference to the supply. There can be many reasons why the demand for a currency declines. The transaction demand of the currency arising from increased international trade could be one reason. Or the demand of the currency by speculators could increase. The extent of business activity of the country in the international market, the levels of employment and the gross domestic product (GDP) determines the transaction demand. The spending on goods and services increases with increase in employment.
