December 29, 2025 — The U.S. Fed latest liquidity operation has sparked fresh debate across financial markets, after reports surfaced that the central bank injected nearly $30 billion into the system. While headlines framed it as aggressive money creation, the reality is more technical and far less alarming.
On October 31, 2025, the Fed conducted a $29.4 billion overnight repo operation to send liquidity through its Standing Repo Facility (SRF). This marked the largest single-day usage of the facility in over two decades. The move aimed to ease short-term funding stress as bank reserves slipped to four-year lows near $2.8 trillion, following an extended period of quantitative tightening (QT).

Crucially, this was temporary liquidity, not permanent stimulus. Funds were repaid the following day, leaving the Fed’s balance sheet unchanged.
The operation occurred at a sensitive moment for money markets. Month-end balance sheet constraints, regulatory reporting deadlines, and heavy Treasury issuance converged at once. As a result, short-term funding conditions tightened faster than usual.
Through the Standing Repo Facility, eligible counterparties exchanged high-quality collateral — primarily U.S. Treasuries — for overnight cash. Reports indicate that total SRF usage exceeded $50 billion across multiple tranches that day, far above recent norms.
At the same time, the Overnight Reverse Repo (ON RRP) facility absorbed roughly $51.8 billion, as other institutions parked excess cash with the Fed. Together, these offsetting flows helped stabilize rates without injecting net liquidity into the system.
In short, the Fed stepped in to smooth market plumbing, not to rescue failing institutions.
Repo facilities form the backbone of short-term liquidity management in modern finance. They allow the Federal Reserve to fine-tune cash conditions while keeping the federal funds rate within its target range.
As summarized in the table above, different facilities serve different purposes:
Markets responded with little drama. Treasury yields remained stable, equities saw limited movement, and funding rates normalized quickly after the operation. Investors largely viewed the move as preventive, not reactive.
The timing also mattered. Just weeks later, the Fed announced it would end balance sheet runoff on December 1, 2025, shifting to full reinvestment of maturing securities. In addition, reserve-management Treasury bill purchases, roughly $40 billion per month have since supported liquidity into year-end.
Rather than signaling crisis, analysts see the repo spike as a byproduct of QT nearing its practical limits.
