Total US public debt outstanding stood at $40.55 trillion on Nov. 3, with borrowing split between public investors and government accounts, the Department of the Treasury said.
The total rose $298.3 billion, or 0.7%, from Oct. 5. It increased $2.54 trillion, or 6.7%, from Nov. 3, 2025, providing comparisons over about a month and a year.
Debt held by the public accounted for $32.77 trillion of the outstanding balance. Intragovernmental holdings, debt held within the federal government, accounted for the remaining $7.78 trillion.
The public portion was the larger of the two components. Both are included in the $40.55 trillion total, which covers debt outstanding rather than the interest expense attached to it.
Accrued interest expense totaled $63.1 billion in September and $800 billion for fiscal 2026 through Sept. 30, the Treasury said. September was the latest month supplied for interest expense.
The interest figures therefore cover an earlier period than the November debt balance. The monthly amount covers September alone, while the fiscal-year figure includes interest accrued through that month.
Treasury notes accounted for the largest interest expense among the categories supplied, at $43.5 billion in September. Their fiscal-year total reached $498.3 billion, also the largest category.
Treasury bonds followed with $15.3 billion in September and $178.2 billion for the fiscal year. Notes and bonds ranked first and second on both measures of accrued interest expense.
Inflation compensation on Treasury Inflation-Protected Securities, known as TIPS, accounted for $69.7 billion over the fiscal year. That was the third-largest fiscal-year amount among the categories supplied.
The same inflation-compensation category recorded negative interest expense of $452 million in September. It was the only category supplied with a negative amount for the month, despite its positive fiscal-year total.
Treasury floating rate notes accounted for $2.3 billion in September interest expense and $26.7 billion for the fiscal year. Those amounts placed them behind conventional notes and bonds for the month.
A separate category for inflation-protected securities recorded September interest expense of $2.1 billion. Its fiscal-year total was $24.4 billion, below the separately listed inflation-compensation amount for those securities.
State and local government certificates of indebtedness, notes and bonds accounted for $218.9 million in September interest expense. The fiscal-year amount for that category totaled $2.7 billion.
That state and local government category had the smallest positive monthly expense among those supplied. It also had the smallest fiscal-year total among the listed interest categories.
