The Fed pivoted in December from shrinking its holdings to expanding them again, rolling out what it calls reserve management purchases, or RMPs, focused on shorter-term U.S. Treasury bills. As the meeting record put it, "Accordingly, participants assessed that it was appropriate to begin RMPs and initiate purchases of shorter-term Treasury securities to maintain an ample supply of reserves over time." The minutes also stated that, "With the continued increases in the spreads between money market interest rates and administered rates, as well as some other indicators of tightening money market conditions, participants judged that reserve balances had declined to ample levels."
At that gathering, officials cut the federal funds rate corridor by 25 basis points, setting it at 3.50-3.75 percent, and portrayed the balance-sheet adjustment as a technical change. The manager's briefing to the Committee said, "In light of this projected decline in reserves as well as recent developments in money markets, the manager recommended that the Committee consider starting reserve management purchases (RMPs) this month to maintain an ample level of reserves on an ongoing basis," adding that because reserves were expected to fall notably in mid to late April, it would be "prudent to start RMPs soon, maintain a somewhat elevated pace of net purchases until then, and then decrease the monthly pace substantially thereafter." Chair Jerome Powell underscored the intent in his press conference, saying purchases were "solely for the purpose of maintaining an ample supply of reserves over time, thus supporting effective control of our policy rate".
QT had been running since 2022 to drain excess liquidity built up first after the 2008 Global Financial Crisis and then much more during the pandemic, when the Fed's balance sheet climbed from roughly $4 trillion to nearly $9 trillion. As post-pandemic inflation at times ran many multiples above the 2 percent goal, the FOMC leaned on QT and, over roughly three and a half years, reduced the balance sheet by about $2.4 trillion, bringing the total close to $6.6 trillion by early December 2025.
By then, the costs of pressing on looked bigger. Strains were showing up in short-term funding, especially overnight repo, and bank reserve balances were slipping toward levels officials viewed as barely sufficient. The typically quiet standing repo facility began rising sharply, and measures like SOFR drifted toward the top of the target range, a sign that reserves were getting too tight.
They feared a repeat of the 2019 repo turmoil, when funding costs spiked, jumping from roughly 2 percent to as high as 8-10 percent. To counter that possibility, officials determined that purchasing short-maturity Treasuries would best bolster funding conditions.

The restart of asset purchases coincided with the Fed's third consecutive rate cut of the year, putting policy firmly in an easing stance designed to keep liquidity from turning into a significant drag on credit markets. The Fed is framing RMPs as a plumbing fix rather than a push to juice demand or suppress long-term yields. Even so, the mechanics look familiar: the balance sheet expands, reserve balances rise, and liquidity increases.
Markets welcomed it. Short-term rates eased, and the S&P 500 responded positively as expectations for further cuts firmed. PGIM Fixed Income's chief investment strategist, Robert Tipp, described the resumption of balance-sheet growth as a "positive development" for liquidity and noted it may steady arbitrage between Treasuries and futures.
There are tradeoffs. Inflation had cooled from its peak but remained above the 2 percent target through late 2025, raising questions about the timing and size of the shift. Critics also argue that, given sizable deficits and heavy issuance, RMPs can resemble the indirect monetization of government debt.
For everyday investors, the near-term takeaway is simple: more liquidity typically supports asset prices, but it can also inflate valuations and sow instability if fundamentals lag. Watch how quickly the balance sheet grows, where short-term rates trade within the Fed's range, and whether inflation progress stalls. Those signals will show whether this is just keeping the pipes clear or quietly turning the liquidity dial up too far.
