This policy, known as a fixed exchange rate system, links the value of a country's currency to that of another currency. It is typically implemented by a government to stabilize their currency and maintain a consistent exchange rate. This means that the value of the currency will not fluctuate as much as it would under a floating exchange rate. In essence, it is a way for a country to control the value of their currency in relation to another currency. This policy can have both advantages and disadvantages for a country's economy, and is an important term to understand in the field of finance.
