Total US federal debt outstanding stood at $40.55 trillion on Nov. 6, with borrowing split between public investors and government accounts, the Department of the Treasury said.
The total rose $268.71 billion, or 0.7%, from Oct. 7. It increased $2.43 trillion, or 6.4%, from Nov. 6, 2025, the department said.
Debt held by the public accounted for $32.76 trillion of the total. Intragovernmental holdings, debt held in federal government accounts, made up the remaining $7.79 trillion.
The public holdings therefore accounted for most of the outstanding debt. The two categories together comprised the $40.55 trillion total recorded on Nov. 6.
Accrued interest expense totaled $73.5 billion in October, the department said. That was also the total for fiscal year 2027 through Oct. 31, the latest month supplied.
The interest figures measure expense accrued on outstanding debt during the month. They are separate from the debt balance, which records the amount outstanding on a particular date.
Treasury notes accounted for the largest interest category, at $45.8 billion in October. Treasury bonds followed at $16 billion, making those two categories the largest components of the month's accrued interest expense.
Both categories had the same amounts for the fiscal year to date. Notes accounted for $45.8 billion through October, while bonds accounted for $16 billion.
Inflation compensation on Treasury Inflation-Protected Securities, whose value adjusts for inflation, accounted for another $6.4 billion. The department listed that expense separately from interest on the securities themselves.
Floating rate notes accounted for $2.6 billion of October's accrued interest expense. A separate category for inflation-protected securities accounted for $2.5 billion during the same month.
The fiscal year totals for those categories also matched their October amounts. Inflation compensation accounted for $6.4 billion, floating rate notes for $2.6 billion and inflation-protected securities for $2.5 billion.
Interest on state and local government certificates of indebtedness, notes and bonds totaled $227.1 million in October. The corresponding fiscal year expense was also $227.1 million.
The debt and interest figures cover different reporting dates. The outstanding balance was recorded on Nov. 6, while the latest interest figures cover the month through Oct. 31.
The monthly debt comparison runs from Oct. 7 to Nov. 6, a period of about one month. The annual comparison uses Nov. 6 in both 2025 and 2026.
