The federal government's budget deficit reached $2 trillion after just 11 months of fiscal year 2026, while debt-servicing costs continue to put pressure on the federal budget. Gross national debt crossed $40 trillion for the first time in history in August, and the bill for carrying that debt is starting to reshape the federal budget in ways that are hard to ignore.
The Congressional Budget Office reported that the 11-month deficit came in at $2 trillion, according to Fox 5 New York, a figure that was actually $6 billion lower than the same period last year — but only because of a timing shift in certain payments around Labor Day 2025. Strip out that quirk, and the CBO found federal spending would have actually increased by $235 billion, or 4%, a more accurate read on the government's underlying trajectory.
Net interest outlays on the public debt rose 12% during the first 11 months of the fiscal year, according to the Congressional Budget Office. That $111 billion year-over-year jump in debt service reflects both a larger debt base and elevated long-term interest rates — a dynamic that shows no sign of reversing given where markets currently sit.
Treasury Yields and the Debt Milestone
The 10-year U.S. Treasury yield reached 4.8% on September 9, its highest level since 2023, per the Committee for a Responsible Federal Budget. Higher yields on newly issued government bonds translate directly into steeper borrowing costs, compounding the same interest burden already squeezing the budget. That pressure arrived just as gross national debt eclipsed $40 trillion on August 18, up from the $39 trillion mark reached less than five months earlier in March, per the same organization's tracking.
Maya MacGuineas, president of the Committee for a Responsible Federal Budget, warned that failing to reduce deficits risks leaving future generations with irreversible damage. She also said federal government borrowing this year has already surpassed what was borrowed in the entirety of last year, and cautioned that borrowing may rise further in September, the final month of the fiscal year.
Where the Spending Growth Is Coming From
Mandatory spending programs drove much of the increase in federal outlays. Social Security benefit spending rose 5% from last year, an increase of $78 billion tied to both higher average benefit amounts and a growing number of beneficiaries. Medicare spending climbed 8% because of increased enrollment, adding $73 billion, while Medicaid outlays rose 8% due to higher costs per enrollee, an increase of $47 billion.
Department of Veterans Affairs outlays grew 14% during the same 11-month period, an increase of $41 billion, according to the Congressional Budget Office — one of the largest year-over-year percentage jumps among executive departments, driven by more veterans receiving benefits and higher per-person spending. Department of Defense spending itself rose 5%, an increase of $41 billion, reflecting higher spending on military personnel and research and development. Department of Education spending, by contrast, fell 56%, a drop of $79 billion, partly reflecting a net reduction in estimated student-loan costs.
Tariffs, Tax Receipts and a Widened Forecast
On the revenue side, individual income-tax receipts rose 8%, an increase of $189 billion, and payroll taxes increased 3%, adding $50 billion. Corporate income taxes declined $96 billion, a 25% drop attributed to 2025 tax reforms under the One Big Beautiful Bill Act. Customs duties including tariffs increased just 1%, or $1 billion, a muted gain that the CBO tied to a Supreme Court tariff decision that reduced customs duty collections.
That legal disruption helped push the CBO's full-year fiscal 2026 deficit estimate up to $2.1 trillion in August — $200 billion higher than its February baseline — as court-ordered tariff refunds and lower duty collections cut into expected federal receipts, according to the Congressional Budget Office. Separately, changes in federal trade policy have affected the long-term fiscal outlook.
A Debt Load Already Bigger Than the Economy
Debt held by the public has already exceeded the size of the entire economy, and the rolling 12-month deficit for the period ending in August reached $1.8 trillion, equal to roughly 5.5% of GDP, per the Committee for a Responsible Federal Budget. Debt projections remain a central concern in the long-term fiscal outlook.
The International Monetary Fund has separately warned that U.S. general government deficits are on track to remain between 7% and 8% of GDP under current policies, a trajectory that could push public debt to 140% of GDP by 2031, as Hoodline previously reported. The IMF urged Washington to adopt a frontloaded fiscal consolidation plan rather than delaying the reckoning.
Bessent's 3% Target Meets Budget Reality
Treasury Secretary Scott Bessent's fiscal targets were about half the IMF's projected deficit range. Achieving those targets would require sustained deficit reduction over time.
MacGuineas urged lawmakers to agree to a plan to bring deficits down, warning that trust funds relied on by tens of millions of Americans face insolvency in less than a decade. Short-term interest-rate declines have mitigated some of the overall rise in interest payments, but with the 10-year Treasury yield climbing and the debt base continuing to expand, the gap between the administration's stated goals and the government's actual borrowing trajectory remains wide.
