Exchange rate generally refers to foreign exchange rate. The rise of foreign exchange rate means that 100 foreign currency has been replaced by more local currency. The international unit is 100. Take the US dollar and RMB as examples. If the original US$ 65,438+000 is exchanged for 700 yuan RMB and now US$ 65,438+000 is exchanged for 750 yuan RMB, the foreign exchange rate will rise. That is, foreign currency appreciation and RMB depreciation. On the contrary, the foreign exchange rate is falling.
