By Ethan BrooksThe U.S. Department of the Treasury announced on Monday, November 2, 2026, that it expects to borrow $618 billion in privately-held net marketable debt during the fourth calendar quarter spanning October through December 2026. The updated fourth-quarter financing projection is $10 billion lower than the preliminary estimate released in August 2026.
According to the department’s quarterly marketable borrowing release in Washington, the fourth-quarter estimate assumes a closing cash balance of $850 billion at the end of December 2026. Officials attributed the $10 billion downward revision primarily to a higher-than-assumed cash balance at the start of October, which was partially offset by lower projected net cash flows. Excluding that larger opening cash buffer, the underlying fourth-quarter borrowing requirement would have been $24 billion higher than projected in August.
Cash Balance Dynamics and First-Quarter 2027 Outlook
Detailed sources and uses figures show that the Treasury entered the October–December quarter with an opening cash balance of $984 billion, exceeding its August assumption of $950 billion by $34 billion. Because the year-end cash target remains unchanged at $850 billion, drawing down that extra $34 billion in cash reduces net marketable borrowing needs across the final three months of the year. This $134 billion planned cash drawdown compares with a $100 billion drawdown anticipated in the prior quarterly forecast.
Looking ahead to the first calendar quarter of 2027, spanning January through March, the Treasury expects to borrow $800 billion in privately-held net marketable debt. That initial first-quarter estimate assumes a closing cash balance of $1.000 trillion at the end of March 2027. Building the federal cash position from $850 billion at year-end to $1.000 trillion by late March will require $150 billion in additional cash accumulation alongside ongoing fiscal financing.
Review of Third-Quarter Borrowing Performance
Alongside its forward projections, the department finalized its borrowing figures for the July–September 2026 quarter. During that three-month period, the Treasury borrowed $742 billion in privately-held net marketable debt and concluded September with a cash balance of $984 billion. In August 2026, officials had estimated third-quarter borrowing of $739 billion based on an assumed end-of-September cash balance of $950 billion.
The slight increase in third-quarter net marketable borrowing reflected the $34 billion higher-than-assumed closing cash balance, which was largely offset by stronger net cash flows. Excluding the larger end-of-September cash buffer, actual third-quarter borrowing was $30 billion lower than projected in August. Beginning the July–September period with $919 billion in cash, the federal government added $65 billion to its cash reserves rather than the $31 billion originally planned.
Implications for Fixed-Income Markets and Refunding
In the broader Business and fixed-income sectors, quarterly borrowing estimates are closely tracked by institutional investors to gauge future supply of Treasury bills, notes, and bonds. Privately-held net marketable borrowing excludes auction rollovers of securities held in the Federal Reserve’s System Open Market Account, though it includes financing needed to cover any redemptions from that portfolio. Treasury officials also noted that security buyback operations are not expected to materially affect net marketable borrowing because new issuance replaces repurchased debt.
Fixed-income traders and primary dealers use these aggregate financing totals to prepare for specific auction sizes across maturities. Additional details regarding coupon auction sizes and debt management policy were scheduled for release on Wednesday, November 4, 2026, as part of the Treasury’s Quarterly Refunding announcement.
