Federal Reserve to buy $2.12B in Treasury bills as reserve management winds down

The Federal Reserve accepted $2.12 billion in Treasury bills on August 26 as part of its ongoing Reserve Management Purchase program, a relatively modest bite from the $22 billion that dealers submitted for the operation. That acceptance rate, roughly 9.6% of what was offered, tells you something about how selective the central bank is being as it approaches the tail end of this particular buying cycle.

The purchase is part of a deliberate wind-down. The Fed’s Reserve Management Purchases, or RMPs, launched in December 2025 at a pace of roughly $40 billion per month. By June 2026, that figure had shrunk to $10 billion. And no additional RMPs are scheduled between mid-August and mid-September 2026, making this week’s operation one of the last before a planned pause.

What reserve management purchases actually are

These are not QE operations. They are technical, plumbing-level purchases designed to keep enough reserves sloshing around the banking system so that short-term interest rates behave the way the Fed wants them to.

A $2.12 billion T-bill purchase in a system holding approximately $6.7 trillion in assets is a rounding error by design. The Fed’s System Open Market Account, or SOMA, has been growing modestly thanks to these purchases alongside roughly $17 billion in monthly reinvestments from maturing agency securities.

Reserves in the banking system currently sit at approximately $3.1 trillion, a level the Fed considers “ample” for its purposes. That word, “ample,” is doing a lot of work. It means there’s enough liquidity that banks aren’t scrambling for cash in overnight markets, which keeps the federal funds rate pinned inside the Fed’s target range.

How the program evolved

The RMP program kicked off after the Fed concluded its balance sheet runoff in November 2025. Once that process ended, the question became: how do you keep reserves from drifting too low without restarting full-blown QE?

The answer was these targeted T-bill purchases. Starting at $40 billion monthly and tapering steadily, the program was always designed to be temporary and self-limiting.

The New York Fed’s Open Market Trading Desk, which executes these operations, has been transparent about the schedule and sizing. Each operation is announced in advance, and results are published afterward. The $22 billion in submissions against the $2.12 billion accepted suggests plenty of dealer appetite to sell T-bills to the Fed.

What Chairman Warsh is signaling

FOMC Chairman Kevin Warsh has been publicly skeptical of large-scale balance sheet expansions, a posture that aligns with the RMP program’s deliberately modest footprint. His messaging has emphasized flexibility and data dependence, suggesting the Fed views these purchases as adjustable dials rather than permanent policy commitments.

For bond markets, the tapering and upcoming pause in RMPs suggest the Fed sees minimal risk of short-term rate disruptions in the near term. The fact that reserves have reached $3.1 trillion provides a substantial cushion against the kind of overnight rate spikes that rattled repo markets back in September 2019.
