Total US public debt outstanding stood at $40.58 trillion on Nov. 10, an increase of $240.3 billion from about a month earlier, the Department of the Treasury said.
The total rose 0.6% from Oct. 13. Compared with Nov. 10, 2025, outstanding debt increased by $2.46 trillion, or 6.4%, according to the department.
Debt held by the public accounted for $32.8 trillion of the total, while intragovernmental holdings, debt held within the federal government, accounted for $7.78 trillion. The two categories together made up the outstanding balance recorded on Nov. 10.
The department accrued $73.5 billion in interest expense in October, with the monthly record dated Oct. 31. Accrued interest measures expense as it accumulates, rather than the amount of debt outstanding on a particular date.
The fiscal year-to-date interest total also stood at $73.5 billion for fiscal 2027. That figure matched the October amount, so the monthly and fiscal year-to-date figures represented the same expense, rather than separate amounts to be added together.
Treasury notes accounted for the largest interest category, at $45.8 billion in October. The fiscal 2027 total through that month was also $45.8 billion. Interest on notes alone exceeded the combined expense of all the other listed categories.
Treasury bonds ranked second among the listed interest categories, accounting for $16 billion in October and the same amount for the fiscal year to date. Notes and bonds together accounted for most of the month's accrued interest expense.
Inflation compensation on Treasury Inflation-Protected Securities, whose value adjusts for inflation, accounted for another $6.4 billion in October. The fiscal year-to-date amount for that category was also $6.4 billion, making it the third-largest listed component.
The department listed a separate interest category for inflation-protected securities at $2.5 billion for October and for fiscal 2027 to date. That amount was distinct from the inflation compensation expense recorded for those securities.
Treasury floating rate notes accounted for $2.6 billion in accrued interest in October, with the same amount recorded for the fiscal year to date. That category was smaller than inflation compensation but larger than the separate inflation-protected securities interest category.
The category covering state and local government certificates of indebtedness, notes and bonds accounted for $227.1 million in October. Its fiscal year-to-date expense was also $227.1 million, the smallest amount among the interest categories supplied.
