The exchange rate of the US dollar against RMB still fluctuates greatly, which is due to the different performances of market confidence in different periods of the two countries' economies and the result of market commodity adjustment.
For example, the China stock market crash will affect the exchange rate trend. Therefore, it is normal for the exchange rate to fluctuate within a certain range. If it changes only in one direction in a short period of time, it means that something has happened in a country.
If the exchange rates of two countries are exactly the same, it means that the exchange rate of one country is closely linked to that of another country, which inevitably means that a country's monetary policy is not independent enough.
