What is the opposite of quantitative easing?

The opposite of quantitative easing in finance is often referred to as quantitative tightening. This refers to the Federal Reserve or other central banks reducing the amount of money in circulation and increasing interest rates to slow down economic growth and prevent inflation. Quantitative tightening is used as a tool to remove excess liquidity from the financial system and control inflation. This can be achieved through selling government securities, raising reserve requirements for banks, and increasing the federal funds rate. Quantitative tightening is typically implemented when the economy is growing too quickly and there is a risk of overheating, leading to excessive inflation.
