Exchange rate (also known as foreign exchange rate, foreign exchange rate or foreign exchange market) The exchange rate between two currencies can also be regarded as the value of one country's currency against another. 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 to conduct extensive and continuous currency transactions (foreign exchange transactions are conducted 24 hours a day except weekends, that is, from 8: 15 GMT on Sunday to 22:00 GMT on Friday). Spot exchange rate refers to the current exchange rate, and forward exchange rate refers to the exchange rate quoted and traded on the same day, but paid on a specific date in the future).
