Quantitative Easing (QE)

Quantitative easing (QE) is an unconventional monetary policy tool used when conventional interest rate cuts have been exhausted (rates near zero). The central bank — like the Federal Reserve or European Central Bank — creates new money electronically and uses it to buy bonds from banks and institutions. This increases the money supply, lowers long-term yields, and theoretically encourages lending and investment.

QE inflates asset prices. When bonds become expensive (due to central bank buying), investors are pushed into riskier assets like stocks and real estate, driving prices higher. This 'portfolio channel' effect is one reason markets surged dramatically during QE periods (2009–2014 and 2020–2022).

Example: The Fed's QE programs after the 2008 crisis expanded its balance sheet from under $1 trillion to over $4 trillion. The subsequent QE in 2020–2021 pushed it above $9 trillion. Critics argue this fueled inflation; supporters credit it with preventing economic collapse.

Quantitative tightening (the reverse — selling bonds and shrinking the balance sheet) puts downward pressure on markets. The BMInsider Fear & Greed Index captures the market sentiment shifts that often accompany QE and QT announcements.
