The U.S. Treasury sold a record $839 billion of debt in a single week, a milestone that says less about new borrowing than about how heavily Washington now leans on short-term bills that must be refinanced again and again.
The total came from 11 auctions held Oct. 26 through Oct. 29, edging past the $834 billion high set in the same week of 2025. Only about $106 billion of the total was new cash, far below the weekly peak of nearly $362 billion reached in the spring of 2020. The rest went to pay off maturing bills.
Bills carry the load
Treasury bills, which mature in a year or less, made up about $626 billion, or roughly three-quarters, of the week’s sales. The remaining $213 billion came from a $69 billion two-year note, a $70 billion five-year note, a $44 billion seven-year note and a $30 billion two-year floating-rate note. Demand held up: the two-, five- and seven-year notes drew bid-to-cover ratios of 2.59, 2.33 and 2.46, and the floating-rate note drew the strongest bidding of the week. Long-term yields fell over the week, with the 10-year yield slipping below 5%.
The gross figure keeps setting records because the stock of outstanding bills keeps growing. Over the past two years, the Treasury has financed rising deficits mostly by enlarging weekly bill auctions while holding its monthly note and bond sales steady. That approach leaves taxpayers more exposed to short-term interest rates, because bills reprice within weeks, and federal debt now exceeds $40.5 trillion.
Refunding in focus
Since early 2024, the Treasury’s quarterly refunding statements have said coupon auction sizes would stay unchanged for at least the next several quarters. Many bond strategists expect that language to be revisited on Nov. 4. Larger note and bond auctions would add long-dated supply at a time when companies are also borrowing heavily, including Microsoft’s $25 billion bond sale last week. Some rates traders warn that record gross supply could eventually push investors to demand higher yields.
