The price to exchange one U.S. dollar for one unit of a foreign currency is called an exchange rate. The exchange rate of the U.S. dollar varies for different foreign currencies, which fluctuate daily based on a number of factors.
The policies a countryâs government implements can have a significant effect on a currencyâs exchange rate. As policies promote or suppress certain parts of a countryâs economy, those changes can affect how desirable its currency is, in turn affecting the currencyâs exchange rate.
