After the 2008 financial crisis, many central banks used "quantitative easing" to buy large amounts of government bonds, making the market more stable and borrowing cheaper.
Now they want to use "quantitative tightening" to slowly sell these bonds back, reducing the amount of money in the market.
But by 2025, with the economy slowing and government debt high, everyone realizes that the central bank's balance sheet has become key to financial stability.
The UK is a clear example.
The Bank of England slowed down quantitative tightening in September 2025 because fewer people were buying long-term government bonds and long-term interest rates rose, making it harder for the market to absorb new debt.
The US also slowed down due to concerns about insufficient bank reserves, Europe wants to avoid widening interest rate gaps among member countries, and Japan's large bond holdings may also cause volatility.
Quantitative easing also brought two major problems: first, the government has to pay more interest, turning losses into taxpayer burdens; second, the market operation relies more on central banks providing funds and government bonds.
In the future, central banks will find it hard to return to their pre-2008 size, and monetary policy must work more closely with fiscal policy.
