Exchange rate, also known as foreign exchange rate, foreign exchange rate or foreign exchange market, 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. Specifically, it refers to the ratio or parity between one country's currency and another country's currency, or the price of another country's currency expressed in one country's currency.
Exchange rate changes have a direct regulatory effect on a country's import and export trade. Under certain conditions, the devaluation of the local currency, that is, lowering the exchange rate, will promote exports and restrict imports; On the other hand, the appreciation of the local currency, that is, the rise of the exchange rate, plays a role in restricting exports and increasing imports.
