Fed Bank Reserves Fell $88.236 Billion Between September 23 and 30
The Federal Reserve’s October 1, 2026 H.4.1 release shows reserve balances with Federal Reserve Banks at $2,881,686 million as of Wednesday, September 30. The prior release pegged the September 23 Wednesday balance at $2,969,922 million, making the point-in-time drop $88.236 billion over seven days.

Two Fed liability shifts drove a significant chunk of that drain. The Treasury General Account rose $36.729 billion to $984.046 billion by September 30, pulling cash away from the banking system. Total reverse repos climbed $41.158 billion to $361.883 billion, with foreign official and international accounts accounting for $30.080 billion of that increase to $350.344 billion.

This is quarter-end mechanics at work. Tax payments and government receipts flow into the TGA while banks and foreign central banks park cash in reverse repos, compressing the Wednesday snapshot in a pattern that repeats every three months. The number is real; the narrative of a structural liquidity collapse is not yet supported by the data.

The Weekly Average Rose Despite the Snapshot Decline
Here is the number that reframes the story. The weekly-average reserve balance for the period ended September 30 came in at $2,948,090 million, up from $2,930,193 million for the week ended September 23, a gain of $17.897 billion.

The weekly average smooths the daily volatility that a Wednesday snapshot captures in a single freeze-frame. When the two measures diverge sharply, as they did here, it almost always signals a large intra-week swing rather than a persistent trend. Reserves were higher on average across the full week even as they finished lower on Wednesday.
This pattern mirrors how legislative changes to bank deposit flows can create temporary liquidity dislocations without signaling a fundamental shift in system-wide reserve availability.
What the Funding Markets Actually Said on September 30
The secured overnight rate provides a cleaner read on whether the reserve drop translated into any real funding pressure. The New York Fed reported a September 30 SOFR median of 3.90%, with a 99th-percentile rate of 3.99% and $3.230 trillion in underlying volume. As the New York Fed defines it, SOFR is “a broad measure of the cost of borrowing cash overnight collateralized by Treasury securities.”
A stressed quarter-end typically shows the 99th-percentile SOFR spiking well above the median as the most cash-constrained borrowers pay a premium. A spread of just 9 basis points between the median and the 99th percentile, against $3.2 trillion in volume, does not describe a funding squeeze. The plumbing held.
What the Two Reserve Measures Indicate for Readers
The $88.236 billion Wednesday endpoint decline and the $17.897 billion weekly-average increase are measuring the same system through two different lenses. Neither figure alone tells you whether bank reserves are structurally tight or ample; together they tell you that September 30 was a low-point day within a slightly higher-than-average week.
Analysts have cautioned that reserve endpoint data alone does not establish a transmission mechanism into crypto markets or a Bitcoin liquidity squeeze; direct evidence linking bank funding conditions to crypto credit availability would be required before drawing that conclusion.
The crypto Fear and Greed Index sat at 65 (Greed) at the time of publication, and Bitcoin traded near $84,764. Neither reading corroborates a liquidity-driven stress event in digital assets stemming from the reserve shift.
The next H.4.1 release will show whether the Wednesday rebound that the weekly average implies carries forward into October, or whether the endpoint decline was a leading signal of something more sustained. That is the number worth watching.
