Exchange rate can be understood as price. When the exchange rate rises, the price will rise.
There are two main ways to express the exchange rate: one is based on how much local currency the unit foreign currency is converted into, that is, direct quotation, for example, China's 100 USD =637.35 RMB. In this way, the rise of exchange rate means that the unit foreign currency is converted into more local currency, that is, the local currency depreciates; The other is how much foreign currency the local currency is converted into, which is called indirect pricing method. Under this representation, the rise of foreign exchange rate means the appreciation of local currency.
Most countries in the world quote directly, so there is no special explanation. The direct purchase price is the default purchase price, and the exchange rate rises to the depreciation of the local currency. The local currency exchange rate, that is, the local currency price rises and the foreign currency exchange rate falls.
