Quantitative tightening (QT) is the Federal Reserve's process of reducing its balance sheet — the reverse of quantitative easing — by allowing maturing Treasury and agency MBS securities to 'run off' without reinvestment, draining reserves from the banking system and putting upward pressure on long-term interest rates.
QT is the passive or active contraction of the Federal Reserve's System Open Market Account (SOMA). Rather than actively selling securities (which would be disruptive), the Fed primarily conducts QT through 'passive runoff': when a Treasury note or agency MBS it holds matures, the Fed simply does not reinvest the principal — the balance sheet shrinks by that amount. The FOMC sets monthly caps on the amount of runoff permitted; any principal receipts above the cap are reinvested. The Fed's two QT episodes: (1) First QT (October 2017–September 2019): began after the post-QE3 balance sheet stabilized at ~$4.5T; caps started at $10B/month, rising to $50B/month; total reduction was ~$650B. Ended abruptly when repo market stress in September 2019 signaled reserves had fallen too far. (2) Current QT (June 2022–present): started at $47.5B/month (Treasuries $30B + MBS $17.5B), rising to $95B/month (Treasuries $60B + MBS $35B) in September 2022 — the fastest QT in Fed history. The FOMC slowed QT caps in May 2024 (Treasuries to $25B/month). Current balance sheet and SOMA holdings: federalreserve.gov/releases/h41/. Mechanism: QT drains bank reserves — the opposite of QE. As reserves fall, banks have less 'excess' capital to deploy, the federal funds rate can move higher toward the interest on reserve balances (IORB) corridor ceiling, and upward pressure builds on long-term yields through reduced demand for Treasuries. The 'reverse repo' (RRP) facility acts as a pressure valve, absorbing excess reserves when they're high and releasing them as QT proceeds.

As the Fed's balance sheet shrinks, upward pressure on long-term Treasury yields flows through to fixed-rate small business loans, commercial real estate financing, and SBA 7(a) fixed rates. The 2022–2024 QT cycle coincided with SBA fixed rates rising to 13.5%+ — the highest in 15 years — from below 6% at the COVID-era QE trough.
QT puts upward pressure on long-term Treasury yields as the Fed reduces demand for Treasuries. Since many small business fixed-rate products are benchmarked to Treasury yields, QT contributes to higher borrowing costs. Combined with the 2022–2023 rate hike cycle, QT helped push SBA 7(a) variable rates above 14% and fixed rates above 13% — levels not seen since the early 2000s.

A rate hike directly raises the federal funds rate (the overnight interbank rate), which flows through to prime rate, adjustable-rate loans, and short-term borrowing costs. QT raises long-term rates by reducing Fed demand for long-term securities — affecting 10-year Treasuries, 30-year mortgage rates, and long-dated commercial real estate loans. Rate hikes hit variable-rate borrowers fastest; QT hits fixed-rate long-term borrowers hardest. Both were deployed simultaneously in 2022–2023 — creating dual pressure on all points of the yield curve. FOMC statement archive: federalreserve.gov/monetarypolicy/fomc.htm.
The FOMC ends or slows QT when reserve levels approach the 'ample reserves' threshold — the point below which short-term funding markets show stress (as in September 2019 repo market volatility). The Fed slowed the QT pace in May 2024, signaling it was approaching the lower bound of comfortable reserve levels. A formal end to QT (and eventual return to QE) would likely follow a recession or severe financial stress requiring balance sheet expansion.
