The central bank's interest rate hike is a monetary policy, which is regulated by interest rates. When the money supply in the market is greater than the actual money demand, it will raise interest rates to regulate, and when the money supply is less than the actual money demand, it will cut interest rates to regulate. Raising interest rates by the central bank will increase people's willingness to save and reduce funds in the market, thus reducing inflation. Reducing interest rates will increase the scale of market credit, increase the money supply, enhance the liquidity of money and stimulate the growth of market economy.
