There are two major types of foreign exchange regimes: fixed exchange rate policy and floating. As its literal meaning on appearance, a fixed exchange rate is a regime in which a country’s currency exchange rate is tied to the currency of another country or the price of gold. A floating exchange rate policy, instead, gives the currency a much wider range to float without predominant regulatory control. The price of a particular currency in this scenario is almost purely driven by the relative supply and demand of the currency in the foreign exchange market. We will define the exchange rate in our discussion as the rate at which a domestic currency can be converted to one unit of U.S. Dollar, the value of which is assumed unchanged, we will now proceed with our discussion of the fixed-rate system.
