The US Treasury's Monthly Treasury Statement for September 2026 gives the final budget results for fiscal 2026, which ended on 30 September. It records a deficit of $1.992 trillion for the year, up from $1.775 trillion in fiscal 2025. That is an increase of about 12%.
The numbers
- Fiscal 2026 deficit: $1,992,473 million, from the Treasury's table
- Fiscal 2025 deficit: $1,775,369 million
The deficit is the gap between federal spending and revenue across the year, so a wider deficit means more government borrowing.
Reading it
A deficit near $2 trillion matters for bond markets, because more borrowing means more Treasury issuance. In recent weeks, the 10-year Treasury yield has moved from 5.31% to 5.09% (yields report), which shows how supply and rate expectations can pull in different directions.
