Fed’s RMPs Stave Off Liquidity Crisis, Stabilizing Repo Rates Before Spring

The Federal Reserve's Reserve Management Purchases (RMPs) are a direct, mechanical tool to ease short-term funding markets. The program, which began in December 2025, involves the Fed's trading desk buying Treasury securities monthly, injecting fresh reserves directly into the banking system. This action is designed to maintain reserves within an "ample" range, a framework the FOMC established in May 2022 to control short-term rates through administered rates like the interest on reserves, rather than constant reserve supply management.

The specific trigger for this intervention was a critical liquidity event in late 2025. As bank reserves declined, the general collateral (GC) repo rate-a key benchmark for overnight secured borrowing-spiked above the Fed's target range. On October 31, it hit 4.25%, well above the 3.75%-4.00% band. This spike was a clear signal that reserves had fallen into a "scarce" regime, where funding costs become volatile and sensitive to small supply shifts. The Fed's own governor had flagged a reserve level of $2.7 trillion as the threshold for ample conditions; by November, reserves had dipped to $2.8 trillion, just shy of that critical level.

By committing to $40 billion in monthly RMPs, the Fed provides a steady, predictable floor under short-term rates. Each purchase adds to the total reserves available for banks to use as collateral or to meet regulatory requirements. This directly eases pressure in the repo market, where the spike had occurred, and helps prevent the kind of funding stress that can ripple through the financial system. The program is a targeted response to a specific liquidity shortage, using the Fed's balance sheet to restore ample conditions and stabilize the overnight funding market.

The Evidence: Concrete Data on Easing Conditions

The data from recent weeks confirms that the Fed's Reserve Management Purchases (RMPs) are directly easing the tight conditions that sparked the crisis in late 2025. The most telling sign is the near-total disappearance of the Overnight Reverse Repurchase Agreement (ON RRP) facility. Balances have fallen to near zero, a key indicator that the Fed's purchases are successfully absorbing excess liquidity and removing a major source of systemic stress. This is a stark reversal from the $2.5 trillion peak seen in 2023, signaling that the Fed's balance sheet expansion is now acting as a net absorber of cash, not a supplier.

This easing is mirrored in the overnight funding market. The General Collateral (GC) repo rate, which spiked to 4.25% in October, has now stabilized. It is no longer consistently trading above the Fed's target range, a clear sign that the scarcity of reserves has been addressed. The program's mechanics are straightforward: each monthly purchase of $40 billion in Treasury bills adds fresh reserves to the banking system, directly easing pressure in the repo market where the spike had occurred.

The Fed is likely maintaining a robust monthly pace to sustain this easing. The RMPs are being combined with the Fed's ongoing reinvestment of principal payments from its mortgage-backed securities (MBS) holdings. This combination means the central bank is likely buying around $55 billion of T-bills per month through at least mid-April. This steady injection of reserves provides a predictable floor under short-term rates, preventing a relapse into the volatile, scarce regime that characterized the late 2025 liquidity event.

The bottom line is that the RMPs are working as designed. By targeting a specific liquidity shortage, the program has restored ample reserve conditions, stabilized the GC repo rate, and allowed the ON RRP buffer to vanish. This provides a more stable foundation for short-term funding, though it does so by expanding the Fed's balance sheet at a time of high fiscal deficits and shifting foreign demand for Treasuries.

The Cyclical Nature: A Temporary Tool for Liquidity Management

The Reserve Management Purchases (RMPs) are a cyclical tool, not a permanent policy shift. They are a necessary response to a fragile financial system, but they are not a permanent expansion of monetary stimulus. The program exists to manage the ample reserves regime the Fed established in 2022, not to replace it. The ultimate goal remains shrinking the balance sheet-a solvable challenge that requires tradeoffs in rate volatility and Fed intervention.

The Fed's own framework defines this as a temporary state. The "ample" regime is meant to be a steady condition where the Fed controls rates through administered rates like the interest on reserves, not through constant reserve supply management. The RMPs are a targeted intervention to maintain that ample range when it starts to slip. As the Fed's own manager noted, the program was initiated when it judged that reserves declined to the ample range in December, and the Desk was instructed to begin RMPs to maintain reserves within that range. This is a cyclical feature of the current system: the Fed steps in to manage reserves when they become scarce, but its aim is always to return to a state where such active management is not required.

This creates a clear tension. The RMPs are a direct expansion of the Fed's balance sheet, buying $40 billion in Treasury bills monthly. Yet, as officials have argued, a smaller balance sheet is a worthy goal for multiple reasons, including reducing market distortions and preserving policy flexibility. The RMP program is a pragmatic, temporary fix that allows the Fed to navigate the immediate liquidity shortage while the longer-term challenge of balance sheet reduction remains on the table. It is a solvable problem, but one that will require careful management of rate volatility and a willingness to accept some level of Fed intervention as reserves are gradually drawn down.

The bottom line is that the RMPs are a cyclical liquidity tool, not a new permanent policy. They are a necessary feature of the ample reserves regime when that regime faces stress, but they are not a substitute for the ultimate goal of a smaller, less intrusive balance sheet.
