Quantitative Easing
A Fed policy of purchasing Treasury bonds and MBS to inject liquidity, lower long-term yields, and stimulate the economy when short rates are near zero.
Quantitative Easing (QE) is an unconventional monetary policy tool used when the fed funds rate cannot go lower (zero lower bound). The Fed creates bank reserves electronically and uses them to purchase long-duration assets — primarily Treasuries and mortgage-backed securities — directly from banks and dealers.
QE achieves two goals: (1) it injects reserves into the banking system, increasing liquidity; (2) it suppresses long-term yields by increasing demand for duration. Lower long yields reduce borrowing costs for mortgages, corporate bonds, and consumer credit.
A side effect of QE is a powerful boost to risk assets. By suppressing the risk-free rate, QE pushes investors out the risk curve into equities, high-yield bonds, and real assets. The four rounds of Fed QE (QE1–QE4) were major tailwinds for equity bull markets.
