Under the paper money system, countries issue paper money as the representative of metal money, and refer to past practice to stipulate the gold content of paper money by law, which is called gold parity. The comparison of gold parity is the decisive basis of the exchange rate between the two countries. However, paper money cannot be converted into gold, so the legal gold content of paper money often exists in name only. Therefore, in countries where the official exchange rate is implemented, the exchange rate is set by the national monetary authorities, and all foreign exchange transactions must be conducted according to this exchange rate. In countries that implement market exchange rate, the exchange rate changes with the change of money supply and demand in the foreign exchange market.

The exchange rate has an impact on the balance of payments and national income.
