What Quantitative Tightening Means in Plain Terms

Quantitative tightening (QT) is when a central bank shrinks the stock of securities it bought during earlier rounds of asset buying, usually by letting bonds mature without replacing them and sometimes by selling them. The Federal Reserve's most recent round ran from June 2022 until December 1, 2025, by which point its total assets were about 27% below their April 2022 peak.

Key takeaways

Fed total assets peaked at about $8.97 trillion on April 13, 2022, fell to $6.54 trillion by December 3, 2025, and stood at $6.76 trillion on October 14, 2026.
Monthly runoff was capped at up to $60 billion of Treasuries and $35 billion of agency mortgage-backed securities (MBS); the Treasury cap fell to $25 billion on June 1, 2024 and $5 billion on April 1, 2025.
Between June 1, 2022 and December 3, 2025, the overnight reverse repo facility fell from about $1.97 trillion to $2.5 billion, while bank reserves fell by about $464 billion (14%).
Since December 2025 the Fed has bought Treasury bills to keep reserves ample, which Chair Powell said has no implications for the policy stance.

What quantitative tightening is

A central bank's balance sheet lists what it owns (at the Fed, mostly Treasury securities and agency MBS) and what it owes (mainly currency, bank reserves and cash placed in facilities such as the overnight reverse repo facility). Asset purchases, called quantitative easing (QE), enlarge both sides; QT shrinks them.

There are two ways to shrink the asset side. One is runoff: when a bond matures, the central bank collects the principal and does not buy a new bond with it. The other is active sales. The Fed's May 4, 2022 plans describe runoff only: principal rolls off up to a monthly cap and anything above it is reinvested. The Bank of England, by contrast, describes QT as letting bonds mature, actively selling them, or a combination of the two.

QT, QE and rate hikes compared

The policy rate sets the price of overnight money. QE and QT change how many longer-term securities private investors must hold, and Fed staff research links them mainly to longer-term yields through the term premium (see the section on markets below). On March 15, 2020, to support smooth market functioning, the FOMC said it would raise its holdings of Treasuries by at least $500 billion and of agency MBS by at least $200 billion.

Tool	What the central bank does	Balance sheet	Main channel
Rate hike	Raises the target range for the federal funds rate	No direct change	Cost of short-term borrowing
QE	Buys securities in the market	Grows	Longer-term yields, reserves
QT	Redeems securities without reinvesting, or sells them	Shrinks	Longer-term yields, reserves

The Fed's January 26, 2022 principles called changes in the federal funds rate the primary means of adjusting policy. Balance sheet reduction would start only after rate increases had begun and would proceed in a predictable manner.

How runoff works and what it drains

The monthly caps

The most that could roll off in a month was the Treasury cap plus the agency cap. For Treasuries, the implementation notes told the New York Fed to redeem maturing coupon securities up to the cap and to redeem Treasury bills to make up any shortfall, so Treasury runoff could reach the cap even when few coupon securities matured. The plan had no such make-up for MBS, so their runoff depended on how fast homeowners repaid principal.

The table shows maximums computed from the caps, not actual runoff.

Period	Months	Treasury cap	MBS cap	Max per month	Max over period
Jun-Aug 2022 (initial)	3	$30B	$17.5B	$47.5B	$142.5B
Sep 2022-May 2024	21	$60B	$35B	$95B	$1,995B
Jun 2024-Mar 2025	10	$25B	$35B	$60B	$600B
Apr-Nov 2025	8	$5B	$35B	$40B	$320B

Over the 42 months, the caps allowed at most $1,640 billion of Treasury runoff and $1,417.5 billion of MBS runoff. The Fed's summary reports actual redemptions of about $1.6 trillion of Treasuries and $600 billion of MBS, more than $2.2 trillion in all. By this arithmetic, Treasury runoff came close to its ceiling while MBS used well under half of theirs; that is a comparison, not a Fed explanation.

Reserves and the reverse repo facility

When the Fed's assets shrink, its liabilities shrink by roughly the same amount. Two liabilities matter here. Reserves are the deposits banks hold at the Fed. In the overnight reverse repo (ON RRP) facility, the New York Fed sells a security to an eligible counterparty and agrees to buy it back; counterparties include money market funds, banks and government-sponsored enterprises.

Measure (FRED)	Jun 1, 2022	Dec 3, 2025 (runoff ended)	Oct 14, 2026 (latest)
Total assets (WALCL)	$8,915B	$6,536B	$6,756B
Reserve balances (WRESBAL)	$3,322B	$2,858B	$3,022B
ON RRP (RRPONTSYD)	$1,965B	$2.5B	$0.2B

Over the runoff period (June 1, 2022 to December 3, 2025), total assets fell $2,379 billion, ON RRP fell about $1,963 billion and reserves fell $464 billion. ON RRP did not drain at once: it first rose to about $2,554 billion on December 30, 2022. In a March 2025 speech summarized by the New York Fed, Roberto Perli, who manages the Fed's portfolio, said runoff had not materially reduced reserves because ON RRP balances fell instead, and that once ON RRP neared zero, reserves would likely shrink next. The FRED figures fit that account but do not prove why each balance moved.

The "ample reserves" idea

In what the Fed calls its ample reserves regime, short-term rates are steered mainly by the rates the Fed sets rather than by day-to-day interventions, as Powell described it in December 2025. The May 2022 plans said runoff would stop once reserves were "somewhat above" the ample level. The Fed has not put a dollar figure on ample; Perli pointed to how responsive the federal funds rate is to reserves, among other indicators.

What happened after runoff ended

The New York Fed calls the bill buying reserve management purchases (RMPs) and sizes them for seasonal swings and trend growth in demand for Fed liabilities. At the December 10, 2025 press conference, Powell said the purchases were "for the sole purpose of maintaining an ample supply of reserves over time," and that implementation issues "are separate from—and have no implications for—the stance of monetary policy." The New York Fed's operational schedule, checked October 21, 2026, shows about $40 billion a month through April 13, 2026, then $25 billion, then $10 billion a month to August 13, with none from August 14 and none planned through November 13, 2026.

What QT may do to markets

Longer yields and the term premium

The term premium is the extra yield investors want for holding a long bond instead of rolling over short ones. A June 2022 Fed staff note estimated in a model that a one-time permanent cut in holdings equal to 1% of GDP raises the 10-year term premium by about 10 basis points, all else equal. By the note's estimate, without runoff the term premium would have been about 60 basis points lower by the third quarter of 2024. It judged the planned reduction of about $2.5 trillion roughly equivalent to raising the policy rate a little more than 50 basis points on a sustained basis.

The authors stress considerable uncertainty: the model rests on pre-2008 data and leaves out signaling and market-functioning effects. The note gives no figure for stock prices, mortgage rates or growth, and actual yields from 2022 to 2025 also reflected inflation, rate decisions and Treasury issuance, so the observed path does not measure QT alone.

Liquidity strains

The clearest warning came weeks after the first round ended. A Fed note on September 2019 money markets reports that reserves fell by about $120 billion over two business days around a corporate tax date and Treasury settlements, to $1.34 trillion, the lowest since 2012. The secured overnight financing rate (SOFR) printed at 2.43% on September 16 and rose above 5% on September 17, while the effective federal funds rate moved above its target range. Repo operations of up to $75 billion a day calmed rates, and on October 11 the Fed announced bill purchases of about $60 billion a month. The note links the episode to declining reserves and rising Treasury supply held by dealers, and calls the size of the moves surprising.

Reserves were $3,022 billion on October 14, 2026, but the strain point is not fixed: Powell noted that demand for Fed liabilities, including reserves, rises over time as the economy grows.

How other central banks compare

European Central Bank: it discontinued reinvestments under its asset purchase programme as of July 2023, and on December 12, 2024 it confirmed the end of pandemic programme reinvestments at the end of 2024.
Bank of England: it uses active sales as well as runoff. In September 2025 its Monetary Policy Committee voted 7–2 to cut the policy gilt stock by £70 billion over October 2025 to September 2026, including £21 billion of sales. In September 2026 it voted unanimously to unwind the remaining stock to zero by the end of 2034, at an average of £46 billion a year with £20 billion of sales a year.

Frequently asked questions

Did the Fed sell bonds during QT?

No sales were announced: the 2022 plans set monthly caps on maturing securities and reinvested principal above them. The Bank of England, by contrast, sells gilts as part of its QT.

Is QT still happening in the US?

No. Runoff ended on December 1, 2025. Total assets have since grown by $220 billion (December 3, 2025 to October 14, 2026, H.4.1 data on FRED), a figure that includes items other than bill purchases.

Are reserve management purchases the same as QE?

The Fed treats them as different. Powell described them as purely for keeping reserves ample, with no implications for the policy stance. They are mainly Treasury bills; the December 2025 directive allows other Treasuries with up to three years left to maturity only if needed. At $10 billion to $40 billion a month, they are also far smaller than the March 2020 commitments.

Why did QT stop with reserves near $2.9 trillion?

The Fed's summary says money market conditions suggested reserves were approaching the ample level. In December 2025 Powell said money market rates had kept tightening relative to the Fed's administered rates, and that the Committee judged reserves had declined to ample levels.

Is the balance sheet back to its pre-pandemic size?

No. Total assets were $4,159 billion in late February 2020 and $6,756 billion on October 14, 2026, about 62% higher. They are about 25% below the April 2022 peak.
