Fixed exchange rate

A fixed exchange rate, sometimes called a pegged exchange rate, is a type of exchange rate regime wherein a currency's value is matched to the value of another single currency or to a basket of other currencies, or to another measure of value, such as gold.

A fixed exchange rate is usually used to stabilize the value of a currency against the currency it is pegged to. This makes trade and investments between the two countries easier and more predictable, and is especially useful for small economies where external trade forms a large part of their GDP.

It can also be used as a means to control inflation. However, as the reference value rises and falls, so does the currency pegged to it. In addition, according to the Mundell-Fleming model, with perfect capital mobility, a fixed exchange rate prevents a government from using domestic monetary policy in order to achieve macroeconomic stability.

There are no major economic players that use a fixed exchange rate (except the countries using the Euro). The currencies of the countries that now use the euro are still existing (e.g. for old bonds). The rates of these currencies are fixed with respect to the euro and to each other. The most recent such country to discontinue their fixed exchange rate was the People's Republic of China, which did so in July 2005
