Quantitative Tightening

The Fed shrinking its balance sheet by letting bonds roll off, draining liquidity from markets.

Also known as: QT, Balance Sheet Runoff

What it is

Quantitative tightening is the process of the Fed reducing its bond holdings, usually by allowing securities to mature without reinvestment. It is the reverse of quantitative easing. It removes liquidity and can pressure asset prices and funding markets.

What it does

QT tightens financial conditions beyond rate policy, pressuring risk assets and raising the risk of funding-market stress. Investors watch runoff pace and reserve levels for liquidity signals. Slowing or ending QT can be a relief catalyst.

The evidence

Balance-sheet runoff has coincided with tighter liquidity conditions and periodic stress in short-term funding markets.

QT effects are diffuse and hard to isolate; blaming any single selloff on runoff often oversimplifies.

Cautions

The Fed can pause or taper QT abruptly, reversing the liquidity narrative.
