The amount of money U.S. banks hold in reserve accounts at the Federal Reserve fell by $59.5 billion in the latest weekly reporting period, while the federal government’s cash balance at the central bank increased by $68.6 billion.
The October 22 Federal Reserve release, covering the week ended October 21, recorded average reserve balances of $2.963 trillion and an average Treasury General Account (TGA) balance of $952.0 billion.
The opposing movements raise a question for financial markets: how much of the reserve decline reflects cash moving into the Treasury’s account, and how much was offset by changes elsewhere on the Fed’s balance sheet?
An Investozora analysis of the Federal Reserve’s H.4.1 tables shows that the Treasury cash increase was larger than the net decline in reserves. Other balance-sheet movements partly offset the shift, while the Fed’s total assets changed relatively little.
Reserve Decline Explained
The Fed reported that average reserve balances fell by $59.533 billion from the previous reporting week, reaching $2.963 trillion. Average balances in the Treasury General Account rose by $68.629 billion to $952.002 billion.
The two changes were measured over the same reporting period, making them directly comparable within the Fed’s balance sheet accounting framework. However, they are not two independent measures of money leaving the financial system.
Bank reserves are deposits that eligible depository institutions maintain at Federal Reserve Banks. The TGA is the federal government’s operating account at the central bank. When payments transfer funds from commercial-bank accounts to the Treasury, the corresponding settlement can reduce banking-system reserves and increase Treasury deposits, other things equal.
Treasury payments into the private sector can reverse that movement. The accounting relationship is important, but it does not establish that every dollar of the weekly Treasury balance increase came directly from banking reserves. Changes in Fed assets and other liabilities also influence the aggregate reserve balance.
Investozora calculated that the $68.629 billion TGA increase exceeded the $59.533 billion reserve decline by $9.096 billion. That difference is an accounting comparison, not a separate liquidity injection or a measure of funds returned to stocks and bonds.
Balance Sheet Offsets
The H.4.1 statistical tables identify the other movements necessary to reconcile the figures. Factors supplying reserve funds declined by $713 million during the reporting week. Factors absorbing reserves, excluding reserve balances themselves, increased by $58.820 billion.
The difference produces the published $59.533 billion reserve decline: $0.713 billion change in reserve-supplying factors, minus $58.820 billion change in reserve-absorbing factors, equals a $59.533 billion decrease.
Within the absorbing category, the $68.629 billion increase in Treasury deposits was partly offset by a combined $9.809 billion decline in other reserve-absorbing factors.
Reverse repurchase agreements fell by $4.953 billion on a weekly-average basis. Currency in circulation declined by $2.006 billion, while other liabilities and capital fell by $2.181 billion. Those shifts, together with smaller movements, moderated the effect of the Treasury balance increase in the accounting reconciliation.
The distinction matters because the headline Treasury movement cannot be interpreted in isolation. A lower balance in the Fed’s reverse repo facility or changes in other non-reserve liabilities can help absorb fluctuations that otherwise would appear in bank reserves. Reserve management operations and changes in Fed credit can also matter.

Week ended October 21, 2026 · Change in billions of dollars
| Component | Reserve effect | Accounting explanation |
|---|---|---|
| TGA rise | −$68.629B | Higher Treasury deposits absorb reserve funds, other factors unchanged. |
| Other offsets | +$9.809B | Net decline in reserve-absorbing factors other than the Treasury General Account. |
| Supply change | −$0.713B | Decrease in factors supplying reserve funds. |
| Net reserves | −$59.533B | Result of all three movements; not an additional component. |
Investozora calculation: −68.629 + 9.809 − 0.713 = −59.533 ($ billions). Bars show signed effects on reserves, not total Treasury balances.

The week’s figures therefore document a shift in the composition of Federal Reserve liabilities more clearly than they document any independent tightening of financial conditions.
Weekly Versus Daily
Another important distinction appears when the weekly averages are compared with balances recorded on Wednesday, October 21. The Fed’s consolidated condition statement showed reserve-related depository institution deposits of $2.970 trillion on October 21, down $61.333 billion from October 14.
The Treasury General Account stood at $945.153 billion, up $59.330 billion over the same Wednesday-to-Wednesday comparison. Those changes differ from the $59.533 billion and $68.629 billion movements in the headline because the headline uses averages of daily observations for successive reporting weeks, not two Wednesday closing snapshots.
Both approaches are legitimate, but mixing them would produce a misleading calculation. The Treasury’s Daily Treasury Statement provides a separate view of operating cash movements. It records deposits and withdrawals on a modified cash basis and can help explain why the government’s closing balance changes between individual business days.
The distinction also matters for analysts reviewing earlier reserve movements or comparing the latest figures with prior Treasury cash shifts. A single closing balance does not necessarily describe the average amount of cash held during an entire week.
Liquidity Implications
The reserve decline is relevant to liquidity monitoring, but the H.4.1 release does not demonstrate that the banking system has entered a period of reserve scarcity. The Federal Reserve Bank of New York’s September 2026 discussion of ample reserves explains that changes in non-reserve Fed liabilities, including the Treasury General Account, affect reserve balances in the opposite direction when other factors are unchanged.
Under the current operating framework, the central bank also conducts reserve management purchases intended to maintain ample reserves. The New York Fed’s operational guidance describes purchases of Treasury securities and reinvestment arrangements under the relevant FOMC directive. That framework is different from assuming that one weekly decrease automatically signals a funding shortage.
To establish whether reserves are becoming less ample, analysts would need additional evidence from short-term money markets, including the federal funds rate relative to administered rates, secured overnight financing rates, repo-market pressures and demand for central bank liquidity facilities.
The Fed’s monetary policy framework and the broader mechanics of quantitative tightening offer context, but neither replaces evidence from the week’s funding conditions. The numbers also do not establish a causal connection to stock prices, Treasury yields or other asset-market movements. Such a finding would require appropriately timed market records and an analysis of competing drivers.
Historical Perspective
The October 21 weekly-average reserve balance was $29.570 billion higher than the comparable figure a year earlier, according to the Fed’s H.4.1 table. The Treasury General Account average was $44.001 billion higher year over year. That comparison is materially different from the latest weekly movement.
It shows that a large week-over-week decline can occur even when the reserve balance remains above its level a year earlier. The year-over-year figures alone, however, cannot establish whether reserves are ample relative to the banking system’s current demand.
Fed securities holdings also present a different picture from the reserve decline. Average outright securities holdings increased $492 million during the latest week, while the consolidated balance sheet showed total assets declining approximately $2.035 billion between Wednesday observations.
The relatively modest total-asset movement reinforces why the week’s reserve decline should not be described as a $59.5 billion reduction in the Federal Reserve’s overall balance sheet. The relationship between the Fed’s securities portfolio, non-reserve liabilities and reserve balances is also central to understanding the System Open Market Account.
For the next assessment, the crucial evidence will be whether the Treasury balance remains elevated, whether reserve balances recover as government cash flows reverse, and whether overnight funding markets show associated pressure.
The next scheduled weekly H.4.1 release is the natural update point, supplemented by daily Treasury cash figures and observable money-market conditions. A further decline in reserves alongside sustained funding-rate pressure would warrant a different assessment from a temporary reserve decline accompanied by stable trading conditions.
