Quantitative Easing – Definition & Examples

Definition: A monetary policy tool where the central bank buys long-term securities to inject money into the economy when short-term rates hit zero.

Detailed Explanation

When the federal funds rate can't go lower, the Fed can still ease policy by buying bonds (government and mortgage-backed), pushing down long-term rates, injecting reserves, and signaling commitment to easy policy. QE was used extensively after 2008 and during COVID, expanding the Fed's balance sheet from under $1 trillion to over $8 trillion.

Real-World Example

QE1 in 2008 focused on mortgage-backed securities to unfreeze credit markets. QE during COVID injected trillions, supporting markets and keeping borrowing costs low throughout the economy.

How to Remember It

A monetary policy tool where the central bank buys long-term securities to inject money into the economy when short-term rates hit zero. A useful definition should do more than name the concept. Try to describe Quantitative Easing – Definition & Examples in your own words, give one real-world example, and name one situation where confusing it with a related term would lead to the wrong answer. That habit is especially helpful for AP, IB, and introductory college economics.
