Exchange rate refers to the exchange rate between two currencies, and can also be regarded as the value of one country's currency against another's currency. Exchange rate is also a financial means for a country to achieve its political goals. The exchange rate will change because of interest rates, inflation, national politics and national economies.
The exchange rate is determined by the foreign exchange market. The foreign exchange market is open to different types of buyers and sellers, and extensive and continuous currency transactions (foreign exchange transactions) are conducted 24 hours a day except weekends.
In the short term, the exchange rate of a country (or region) is determined by the demand and supply of foreign currency in that country (or region). Foreigners buying their own goods, investing in their own country and investing in their own currency will all affect the demand for their own currency. Domestic residents want to buy foreign products, invest in foreign countries and speculate in foreign exchange, which affects their money supply.
