Total US federal debt outstanding stood at $40.56 trillion on Nov. 9, including borrowing held by the public and holdings within the government, the Treasury Department said.
The total increased by $258.3 billion, or 0.6%, from Oct. 9. It rose by $2.43 trillion, or 6.4%, from Nov. 10, 2025, the department said.
Debt held by the public accounted for $32.76 trillion of the outstanding balance. Intragovernmental holdings, the portion held within the federal government, accounted for the remaining $7.80 trillion.
The public holdings were the larger of the two components in the Nov. 9 total. Both categories form part of total public debt outstanding, despite the separate label for debt held by the public.
Accrued interest expense totaled $73.5 billion in October, the department said. The figure measures interest accumulated on outstanding debt during the month, rather than the size of the outstanding debt itself.
The fiscal year 2027 total through Oct. 31 was also $73.5 billion. The monthly and fiscal year figures matched across each of the six interest categories supplied by the department.
Treasury notes accounted for the largest interest expense, at $45.8 billion in October and the same amount for the fiscal year to date. That category alone exceeded half the month's total accrued interest.
Treasury bonds followed with $16 billion in accrued interest for October. Their fiscal year total was also $16 billion, placing bonds second to notes among the categories listed.
Inflation compensation on Treasury Inflation-Protected Securities, whose value adjusts for inflation, accounted for $6.4 billion in October. The fiscal year total for that category was likewise $6.4 billion.
The department listed that inflation compensation separately from another category for interest on Treasury Inflation-Protected Securities. The latter accounted for $2.5 billion in monthly expense and $2.5 billion for the fiscal year to date.
Treasury floating rate notes accounted for $2.6 billion in October interest expense. Their fiscal year total matched the monthly figure, putting the category below inflation compensation and above the separately listed inflation-protected securities interest.
State and local government certificates of indebtedness, notes and bonds accounted for $227.1 million in accrued interest. The amount was the same for October and the fiscal year to date, and was the smallest category listed.
The debt balance and interest figures cover different dates. The outstanding borrowing total was recorded on Nov. 9, while the latest accrued interest figures cover October, with a record date of Oct. 31.
