Understanding QE and QT: Two Important Monetary Policy Tools

In recent years, you may have heard economists and market analysts mention two terms: QE and QT. These are powerful tools used by central banks to regulate the economy. Understanding QE and QT will help you grasp why markets can experience significant volatility during certain periods.

What is QE? How central banks increase liquidity

Quantitative easing — or QE — is a policy used by central banks when they want to inject more money into the financial system. Instead of just lowering interest rates, central banks directly purchase financial assets such as government bonds, savings certificates, and other financial instruments. This action increases market liquidity, lowers lending rates, and encourages businesses and individuals to borrow money for investment or consumption.

As a result, the economy is stimulated, businesses expand production, and stock markets often rise. This is beneficial when the economy needs a boost, but QE can also create long-term issues.

Conversely, QT: Tightening money supply and interest rate impacts

Quantitative tightening — or QT — is the opposite of QE. When the economy overheats and inflation rises sharply, the central bank implements QT by selling the assets they have purchased or simply not reinvesting when these assets mature. This reduces liquidity in the system, raises borrowing rates, and slows economic activity.

QT often puts downward pressure on asset prices, causing concern among investors and usually leading to weakness in the stock market. However, QT can help control inflation, which is why the Fed has had to implement this policy.

Fed policy: From QT to QE — An optimistic turning point

The Federal Reserve (Fed) has been implementing continuous QT in recent years to combat high inflation. However, recently, the Fed has shifted course. At the end of last year, when it began cutting interest rates, the Fed also planned to return to QE — providing liquidity back to the financial system. This is an optimistic signal for the market, as it indicates the Fed believes the economy and inflation are under control, and now is the time to promote growth. The transition from QT to QE often creates positive momentum for asset prices and the stock market.
