Quantitative Easing (QE)
Quantitative easing (QE) is when a central bank buys bonds and other assets on a large scale with newly created reserves, to push down longer-term interest rates and ease financial conditions.
How QE works
Normally a central bank steers the economy with its short-term policy rate. When that rate is already near zero and the economy still needs support, it can instead buy government bonds and sometimes other securities, such as mortgage-backed bonds, from banks and investors. It pays with newly created central bank reserves, so its balance sheet grows.
These purchases raise bond prices and lower their yields, which pulls down borrowing costs across the economy. Sellers who receive cash often move into other assets, such as shares or corporate bonds, which can lift their prices too. QE is also a signal that the central bank intends to keep policy loose for a while.
When it has been used
The Bank of Japan used an early form of QE from 2001. After the 2008 financial crisis the US Federal Reserve and the Bank of England launched large programs, and the European Central Bank followed in 2015. During the 2020 pandemic, central banks expanded QE dramatically.
QE and crypto
QE is often described as bullish for crypto and other risk assets, and the 2020 and 2021 period, when QE was very large, coincided with a strong rise in crypto prices. That overlap is real but limited: there are only a few episodes, many other factors were at work, and correlation does not prove that QE caused the moves. Treat QE as one influence on overall liquidity, not as a reliable buy signal.
Criticism and risks
Critics argue that QE inflates asset prices, which mostly benefits people who already own assets, can encourage excessive risk-taking and makes it harder for central banks to exit later. Whether QE contributed to the inflation surge of 2021 and 2022 is debated among economists. QE also does not simply hand money to households; it swaps one financial asset (bonds) for another (reserves).

Frequently asked questions
Is quantitative easing the same as printing money?
Partly. The central bank creates reserves to buy assets, but it does not hand cash to the public directly, and the effect on broad money depends on how banks and investors respond.
What is the opposite of QE?
Quantitative tightening (QT), in which the central bank shrinks its balance sheet by selling assets or letting them mature without reinvesting.
Does QE always push crypto up?
No. It can improve liquidity and risk appetite, but prices depend on many factors, and past episodes are too few to treat as a rule.
