In recent years, due to the appreciation of RMB, a large amount of foreign exchange has flowed into China, and the liquidity in the monetary field has increased. What measures has the central bank taken and why? 1. Selling bonds and tightening monetary policy in open market business.

2. Increase deposit reserve and reduce investment I through multiplier effect.

3, raise interest rates, increase investment costs, reduce investment I.

All three are national macro-control monetary policies. When the economy is overheated, we should adopt tight fiscal and monetary policies to prevent bubbles or inflation.
