The value of differing currencies derives from the strength of the underlying nation's economy. Factors affecting the health of a nation's economy include inflation, interest rates, trade balance and political stability. Weak economies have adverse effects on the nation's currency. For example, if a country is crippled by high inflation and an unstable government, the value of its currency will weaken relative to other currencies. A weakened currency diminishes the purchasing power of the affected country and its citizens.

Most exchange rates are fixed and tied to a benchmark or base currency, such as the US dollar. However, some currencies utilize a floating exchange rate in which the rate of exchange is elastic under particular market forces.

Exchange rates are vital processing worldwide financial transactions.

To complete such a transaction, the Yen must be converted under the current foreign exchange rate to US dollars.
