Reserve balances held by U.S. depository institutions at the Federal Reserve averaged $3.022 trillion in the week ended October 14, a decline of $7.519 billion from the preceding week, according to the Federal Reserve’s latest balance-sheet figures released Thursday, October 15.
The decline occurred despite an $11.598 billion increase in factors supplying reserve funds, as currency in circulation, reverse repurchase agreements and deposits held at the Federal Reserve outside bank reserve accounts contributed to a larger increase in factors absorbing reserves.
The Federal Reserve’s H.4.1 report, Table 1, showed average reserve balances falling from $3.029659 trillion in the week ended October 7 to $3.022140 trillion in the week ended October 14, a decrease of approximately 0.25%, based on Investozora’s calculation.
The report provides a detailed view of how money moves among the Federal Reserve’s balance-sheet accounts. It does not, by itself, establish a shortage of banking-system liquidity or a change in monetary policy.
What Changed in Reserve Balances
The latest decline followed a substantial increase in the previous reporting week, when average reserve balances climbed $81.569 billion. That earlier increase accompanied a $68.421 billion decline in the Treasury General Account (TGA), according to the Fed’s October 8 report.
The latest figures indicate a much smaller movement in reserve balances, with several components of the Fed’s liabilities reversing direction. Average currency in circulation rose $4.443 billion to $2.488264 trillion, while reverse repurchase agreements increased $2.665 billion to $332.191 billion.
Deposits held at Federal Reserve Banks outside depository institutions’ reserve balances rose $9.272 billion to $1.138900 trillion. Within those deposits, the Treasury General Account increased $3.120 billion to $883.373 billion, while other deposits increased $6.149 billion to $246.053 billion.
These movements matter because bank reserves are only one category of liabilities on the Federal Reserve’s balance sheet. When funds move into Treasury deposits or other Federal Reserve liability accounts, the composition of those liabilities can change even without a corresponding policy-rate decision.
The weekly average also differs from the balance recorded at the end of the Wednesday reporting day. The October 14 Wednesday reserve balance was $3.030854 trillion, approximately $8.714 billion above the week’s average. That distinction is important when comparing weekly liquidity developments with market conditions observed on a particular trading day.
Why Reserves Fell Despite Support
The most consequential feature of the October 15 release is the difference between reserve-supplying and reserve-absorbing factors. According to Table 1, the total factors supplying reserve funds averaged $6.806239 trillion, an increase of $11.598 billion. Reserve Bank credit increased $11.680 billion to $6.707650 trillion. Securities held outright increased $5.040 billion, including a $5.019 billion increase in Treasury securities.
Loans at Federal Reserve Banks also increased $3.606 billion to $11.350 billion, primarily reflecting a $3.611 billion increase in primary credit. Those increases would ordinarily support reserve balances if other relevant balance-sheet components remained unchanged. But they did not.
Total factors absorbing reserve funds, excluding bank reserves themselves, rose $19.116 billion to $3.784099 trillion. The increase in absorbing factors exceeded the increase in supplying factors by approximately $7.518 billion, essentially matching the $7.519 billion reported decline in reserves.
The $1 million difference reflects rounding across the published components. This provides an accounting explanation for the reserve decline without requiring an assumption that the Federal Reserve deliberately withdrew the same amount of liquidity through a new policy action.
Investozora Calculation
Using the Federal Reserve’s reported weekly changes: Increase in reserve-supplying factors: $11.598 billion. Increase in reserve-absorbing factors: $19.116 billion. Net reserve movement: $11.598 billion − $19.116 billion = −$7.518 billion.
The calculation reconciles to the official reserve movement within the Fed’s published rounding tolerance. It is an Investozora calculation based on Table 1, not a separate Federal Reserve estimate.
Treasury Cash and Reverse Repos
The latest figures also offer perspective on how quickly bank reserves can change as Treasury balances fluctuate. On October 5, Adarsha Dhakal explained in an Investing.com analysis how a sharp increase in Treasury cash and reverse repurchase agreements coincided with an approximately $88 billion decline in bank reserves around the September quarter-end.
That analysis emphasized that Treasury account movements should not be treated as independently responsible for the entire change in reserve balances without considering the remaining balance-sheet components.
The latest Federal Reserve release illustrates the same accounting relationship on a smaller scale. For the week ended October 14, the average Treasury General Account rose just $3.120 billion, compared with its $68.421 billion decline during the previous week.
Reverse repurchase agreements also moved higher, increasing $2.665 billion after a comparatively small $266 million increase in the preceding week. Together, the latest increases in Treasury deposits and reverse repos totaled $5.785 billion, equivalent to approximately 76.9% of the $7.519 billion reserve decline.
That proportion is an arithmetic comparison, not a measure of independently established causal contributions. Other assets, liabilities and accounting entries also changed during the week. The broader relationship is significant for investors monitoring Treasury financing, short-term funding markets and the distribution of central-bank liquidity.
When Treasury receives payments or raises cash, funds can move from commercial-bank reserve accounts into the government’s account at the Federal Reserve. Treasury spending can produce the opposite movement, although the ultimate effect depends on the full set of accompanying transactions.
Reverse repurchase agreements operate through a different mechanism: they represent a Federal Reserve liability arising from transactions in which the Fed temporarily sells securities subject to an agreement to repurchase them.
Changes in these accounts can therefore affect the amount of liquidity reflected in commercial banks’ reserve balances without directly measuring how much credit banks are willing or able to extend. For further context, Investozora’s earlier reporting on Treasury cash and bank reserves examines the interaction between the Treasury’s cash position and the Fed’s liabilities.
Securities Holdings Continue to Shift
The H.4.1 report also shows changes in the composition of the Fed’s securities portfolio. Average U.S. Treasury securities held outright increased $5.019 billion to $4.569911 trillion in the week ended October 14. Treasury bills accounted for most of that increase, rising $4.725 billion to $565.492 billion.
Meanwhile, average mortgage-backed securities holdings were nearly unchanged at $1.898110 trillion, increasing just $21 million during the week. The year-over-year figures tell a different story. Compared with the corresponding period a year earlier, average Treasury securities holdings were $373.157 billion higher, while mortgage-backed securities holdings were $187.885 billion lower.
These figures indicate a substantial change in the composition of the Federal Reserve’s securities portfolio over the preceding year. The report does not establish that all of the change resulted from a single transaction type or policy mechanism. That distinction matters when analyzing the Fed’s balance sheet or the role of its SOMA portfolio in monetary operations.
The Federal Reserve’s weekly holdings data measure balance-sheet positions. They should not be confused with a comprehensive transaction ledger explaining every purchase, redemption, reinvestment, settlement or valuation adjustment.
What Bank Liquidity Data Shows
Reserve balances are funds that eligible depository institutions maintain in accounts at Federal Reserve Banks. They are important for interbank payments, monetary-policy implementation and the functioning of the financial system. But the aggregate level of reserves does not provide a complete measure of liquidity conditions at every financial institution.
Banks can face different funding needs depending on deposit flows, payments, collateral requirements and their access to money markets. A weekly reduction of $7.519 billion in aggregate reserve balances therefore does not demonstrate that banks broadly face reserve shortages.
It also does not establish that lending conditions tightened by a corresponding amount. The distinction is especially important because the H.4.1 figures are accounting observations rather than a survey of bank funding stress or a forecast of financial conditions.
The Fed’s weekly average data also do not reveal the distribution of reserves across institutions. Aggregate liquidity may remain substantial even while individual institutions experience different funding pressures. A fuller assessment would require additional evidence from short-term money markets, funding rates and bank-level conditions.
What the Next Report Matters
The October 15 release captures a relatively modest weekly decline in average reserve balances after the previous week’s much larger increase. Its most important finding is that reserve-supplying factors increased, but not enough to offset growth in the components absorbing reserve funds.
The Fed’s next regular H.4.1 release is scheduled for Thursday, October 22, and will provide another observation of reserve balances, Treasury deposits, reverse repurchase agreements and securities holdings. The report is normally issued at 4:30 p.m. Eastern Time.
Investors will be able to compare whether Treasury cash continues to rise, whether reverse repurchase agreements absorb additional funds and whether changes in Federal Reserve credit offset those developments. For now, the latest figures establish a measurable shift in the composition of the Federal Reserve’s balance sheet not a demonstrated liquidity crisis or a new monetary-policy decision.
