What this lesson is about

If quantitative easing floods the system with money, quantitative tightening quietly drains it back out. And it's usually a much slower, quieter process than its counterpart.

Part 1 of 2

Quantitative easing (QE) pumps money into the financial system. The Fed does this by buying large amounts of Treasury bonds and mortgage-backed securities. In contrast, quantitative tightening (QT) does the opposite: it shrinks the Fed's balance sheet by cutting back on those same holdings. Instead of selling bonds directly in the market, which can cause disruptions, the Fed prefers a gentler approach called "runoff." This means letting bonds mature naturally without reinvesting the proceeds, allowing total holdings to shrink slowly over time.

This passive method is why QT usually happens at a slower pace than QE. QE often features big, eye-catching purchase announcements that have immediate effects on the market. In contrast, QT's runoff unfolds gradually, month by month, as bonds mature on their own schedules. It's less dramatic, but the cumulative impact can still be significant.

The central bank balance sheetBoth sides grow together. The money to buy the bonds is the liability it just issued.

Part 2 of 2

Insider Angle: QT affects markets in the opposite way of QE. While QE usually lowers longer-term interest rates by adding a major buyer to the bond market, QT puts modest upward pressure on those rates. This happens as the Fed becomes a smaller net buyer and eventually a net non-buyer of bonds. The Fed kicked off a notable QT program in 2022, reversing much of the balance sheet expansion from pandemic-era QE. The pace and final goal of any QT program remain key policy questions that experts closely monitor.
Try This: Check the Fed's total balance sheet size at its recent peak and compare it to the current level. Figure out how much QT has cut total holdings so far.
