Currency is money issued by governments and central banks throughout the world. An exchange rate is the rate at which one currency can be exchanged for another. The value of one currency compared to another for the purpose of exchange is determined by either a “fixed” or a “floating” rate. A fixed rate is one that is set and maintained by a government or central bank. A floating rate is determined in the foreign exchange, or Forex, market by supply and demand. Travelers must buy the currency of the country which they are visiting in order to make purchases in local markets. Although today, both fixed and floating rate currencies are used, most exchange is governed by rates set through a “managed float.”
