Reasons for exchange rate: Under the gold standard system, gold is the standard currency. The monetary units of two countries that implement the gold standard can determine the exchange rate between them according to their respective gold contents. For example, when the gold coin standard system was implemented, Britain stipulated that the weight of 1 pound was 123.27447 grains, and the fineness was 22K gold, that is, the gold content was 1 13.05438+06 grains of pure gold; The United States stipulates that 1 USD has a weight of 25.8 grains and a purity of 900 thousandths, that is, pure gold with a gold content of 23.22 grains. According to the comparison of the gold content of the two currencies, the exchange rate fluctuates on the basis of 1 =4.8665 USD. 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 (Ministry of Finance, Central Bank or Administration of Foreign Exchange), 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.
