The United States Treasury has lowered its estimate for how much it will need to borrow from private investors in the final three months of 2026, putting the figure at $618 billion. The new projection, released on Monday 2 November 2026, covers net marketable borrowing for October through December and sits $10 billion below the estimate the department published in August. At first glance, the smaller number might look like a sign that the government’s financing burden has eased. The details underneath it tell a more mixed story, and that distinction matters for bond investors, for the banks that buy and resell government debt, and for anyone watching how Washington funds a deficit that remains close to $2 trillion a year.
The Treasury’s borrowing estimates are not a record of money already raised. They are forward-looking projections of net sales of marketable securities to private buyers, after accounting for the cash the government expects to hold at the start and end of each quarter. When the department starts a quarter with more cash than it had assumed, it needs to borrow less to cover the same spending gap. When its projected cash flows weaken, it needs to borrow more. Both forces were at work in this update, and they largely offset each other.
The department now expects to end December with $850 billion in cash, exactly the level it assumed back in August. What changed was the starting point. The quarter began with $984 billion in cash, rather than the $950 billion that the August outlook had pencilled in for the end of September. That $34 billion of extra opening cash, on its own, would have reduced the borrowing requirement by the same amount. Weaker projected net cash flows pushed in the opposite direction, adding $24 billion to the need. Put the two movements together and the headline estimate falls by $10 billion, from $628 billion in August to $618 billion now.
Why the US Treasury borrowing estimate fell while the financing need rose
To understand why analysts are cautious about celebrating the lower headline, it helps to separate the cash position from the underlying financing need. If the change in the cash balance is stripped out, the picture reverses: the amount the Treasury needs to raise, before the effect of building up or drawing down its cash pile, is higher than it was in August, not lower. The department plans to run its cash balance down by $134 billion over the quarter, from $984 billion to $850 billion. Adding that drawdown back gives a financing need of about $752 billion on a cash-adjusted basis, compared with roughly $728 billion implied by the August figures.
What happened in the third quarter
The third-quarter outcome gives useful context for the new estimate. Borrowing of $742 billion in July through September was $124 billion higher than the $618 billion now projected for October through December. Much of that drop reflects the swing in the cash balance: the balance rose by $65 billion in the third quarter, whereas it is assumed to fall by $134 billion in the fourth. When cash is being built up, more borrowing is needed; when cash is being drawn down, less is needed. The underlying need, measured without the cash swing, actually rises from the third quarter to the fourth, which underlines how much of the quarter-to-quarter movement is cash timing rather than a change in the government’s spending or revenue path.
Borrowing steps up in early 2027
For the first quarter of 2027, covering January through March, the Treasury projects borrowing of $800 billion. That is $182 billion more than the fourth-quarter estimate, an increase of nearly 30 percent. The step up is again driven mainly by cash assumptions rather than a sudden jump in the financing need. The department assumes its cash balance will rise by $150 billion over the quarter, to $1 trillion at the end of March. Once that build-up is stripped out, the cash-adjusted need for the first quarter comes to roughly $650 billion, below the roughly $752 billion implied for the current quarter.
Wednesday refunding: what traders will look for
The borrowing estimates are only the first half of the Treasury’s quarterly financing cycle. The second half arrives with the quarterly refunding statement, due on Wednesday 4 November 2026, which sets the sizes of the coupon auctions for the coming quarter. That statement is the document traders scrutinise most closely, because it translates the broad borrowing total into specific sales of notes and bonds across different maturities.
In August, the department said that, on its projected borrowing needs, it expected to keep nominal coupon and floating-rate note auction sizes unchanged for at least the next several quarters. It also said it would absorb seasonal or unexpected swings through bill auction sizes and cash management bills, which are shorter-term instruments that can be adjusted more flexibly. That guidance framed market expectations for this week: most dealers expect the Wednesday statement to leave coupon sizes unchanged once again, with any real debate focused on the language around future changes rather than on immediate action.
The refunding statement also covers the department’s buyback programme, which is designed to support liquidity in the market for older Treasury securities. The Treasury has already raised the maximum size of its longer-dated buyback operations to $6 billion, from $2 billion previously. Traders will watch for any further adjustment to buybacks, since changes there can signal how the department views liquidity conditions in parts of the market where trading has been thinner.
Dealers look to 2027 for possible long-end changes
Even though coupon sizes are widely expected to stay put this week, attention has shifted to what might happen in 2027. Primary dealers, the banks that are obliged to bid at Treasury auctions and that advise the department on market conditions, broadly expect that at some point next year the Treasury could reduce the sizes of its 20-year and 30-year bond auctions while increasing issuance of securities maturing in two to 10 years. The idea, as described by market strategists, is to cover the funding gap created by smaller long-dated sales without adding as much supply at the far end of the yield curve, where yields have remained elevated.
One strategist at BNP Paribas in New York has argued that expectations have built up that the Treasury might foreshadow such changes at this refunding, even if no change takes effect immediately. The same strategist cautioned that, because the Treasury has said coupon sizes will stay steady for the next several quarters, any actual adjustment is unlikely before August 2027 at the earliest. That timeline matters: it suggests Wednesday’s statement may hint at direction without committing to a timetable, leaving dealers to parse wording changes for clues.
The case for eventual changes gained weight after the Treasury asked primary dealers in a questionnaire what future adjustments to auction sizes should be considered in light of expected borrowing needs and investor demand. Such questionnaires are a routine part of the department’s consultation, but the question itself signalled that officials are thinking actively about the mix of maturities, not just the total amount to be borrowed. Analysts are divided on some details, including whether benchmark 10-year note auctions could also grow as part of any reshuffle, and whether smaller long-dated sales would do much to bring down long-term yields on their own.
Heavy reliance on Treasury bills
While the debate about coupon auctions looks ahead to 2027, the nearer-term funding story is about bills. The Treasury is expected to lean heavily on short-term bill issuance in the coming quarters to meet its borrowing needs. TD Securities forecasts net bill supply of $678 billion for the period from November 2026 to January 2027, a strikingly large figure that reflects both the scale of the financing requirement and the flexibility bills offer when cash flows are uncertain.
Heavy bill supply has consequences. A strategist at TD Securities has noted that the increase in bill supply, together with rising rate expectations and diminishing inflows into money market funds, has already pushed bill yields higher. Bills are typically bought by money market funds, banks and other cash managers, and when supply rises faster than demand from those buyers, yields must rise to attract additional purchasers. That dynamic can raise the government’s short-term borrowing costs even while it gives the Treasury flexibility on timing.
Over the medium term, Wells Fargo expects bills to reach 24 percent of the outstanding Treasury market, above the pre-pandemic level and close to the post-Second World War average of about 23 percent. The Treasury Borrowing Advisory Committee, a group of market participants that advises the department, has recommended keeping the bill share between 15 percent and 20 percent. A move toward 24 percent would therefore take the bill share above the committee’s recommended range, raising questions about refinancing risk: bills mature quickly, so a larger bill share means more debt must be rolled over in any given month, leaving the government more exposed if markets are disrupted at a refinancing date.
The deficit backdrop
The borrowing estimates sit against a fiscal backdrop that has changed little since the last refunding in August. The federal deficit for fiscal year 2026, which ended on 30 September, came in at $1.992 trillion. That figure, from the Treasury’s final monthly statement for the year, is $217 billion wider than the $1.775 trillion deficit recorded in fiscal 2025. Receipts for the year reached about $5.40 trillion, while outlays totalled about $7.40 trillion, with net interest costs passing $1 trillion for the first time.
For 2027, J.P. Morgan expects the deficit to remain broadly unchanged at about $1.960 trillion, on the basis of limited information about further large fiscal packages. That forecast, if it proves accurate, would still leave the government borrowing close to $2 trillion a year, which is why dealers are focused on the maturity mix rather than on any imminent fall in total borrowing. A deficit of that size requires continuous access to debt markets, and the way that debt is spread across maturities affects both the government’s interest bill and the shape of the yield curve.
What to watch next
The next milestone is Wednesday’s refunding statement, which will confirm coupon auction sizes for the coming quarter and may offer language on future adjustments. After that, attention will turn to the auctions themselves and to how bill supply evolves through November, December and January, the period covered by the TD Securities forecast. Any sharp move in bill yields, or any sign that money market demand is struggling to absorb supply, would be an early signal that the funding mix is under strain.
