US Net Debt Interest Payments Pass $1 Trillion

The U.S. federal budget deficit widened to $1.99 trillion for the fiscal year, marking a 12% increase from the $1.78 trillion gap recorded in fiscal 2025, according to Treasury Department data released on Friday. The final tally shows mounting fiscal pressure as spending outpaced revenue growth, pushing net interest payments on the national debt past $1 trillion for the first time.

Federal Outlays Outpace Revenue Growth as Deficit Hits $1.99 Trillion

Total revenue for the fiscal year rose 3% to reach $5.4 trillion, driven by individual income taxes that brought in more than $2.8 trillion. Corporate income tax receipts provided $381 billion, down about $70 billion from the prior fiscal year due to tax cuts from the One Big Beautiful Bill act passed by Congress. Meanwhile, total government spending increased 6% to $7.4 trillion. Government spending has climbed steadily over the last three years, moving from $5.76 trillion at this point in 2024 to $6.13 trillion in 2025, and reaching $6.65 trillion so far in calendar year 2026. Drivers of this spending include administration priorities such as the Department of Homeland Security, whose budget jumped 146% between 2025 and 2026. The final deficit also expanded because the Trump administration had to issue $144.6 billion in tariff refunds after the Supreme Court ruled that certain global tariffs imposed by the administration were unconstitutional.

Social Security, Medicare, and Trillion-Dollar Interest Payments Drive Outlays

Social Security remained the largest line item in the federal budget at nearly $1.7 trillion, up modestly from roughly $1.6 trillion in fiscal 2025. Medicare followed as the second-largest contributor, costing almost $1.1 trillion compared to slightly under $1 trillion the previous year. Ranking third in government outlays, net interest payments on the public debt topped $1 trillion for the fiscal year, surpassing spending on both defense and Medicaid. Gross interest costs for the fiscal year reached $1.36 trillion with an average interest rate of 3.53%, up from 3.36% at the end of the prior fiscal year. The Peter G. Peterson Foundation estimated that net interest costs represent 3.2% of GDP, breaking the previous record set in 1991, while other analysis placed the figure at 3.4% of GDP. Gross U.S. debt sits at $40.3 trillion following the Treasury Department’s “Debt to the Penny” reading, with publicly held debt at 100% of GDP.

Treasury Rollover Risks and Yields Surpassing Congressional Budget Office Forecasts

With gross debt crossing the $40 trillion threshold, Treasury Secretary Scott Bessent has addressed the borrowing load by issuing more short-term debt while retiring long-term obligations. This strategy leaves roughly one-third of publicly held debt—more than $10 trillion—maturing within the next 12 months, requiring the federal government to roll it over at higher market rates. Investor anxiety over mounting debt levels has driven market yields upward. The 10-year Treasury yield recently climbed above 5%, moving past the Congressional Budget Office’s earlier forecast of 4.1% for this year and 4.2% for 2027.

Economic Growth Projections Versus Political Spending Choices

Treasury Secretary Scott Bessent has argued that the administration can grow its way out of the debt burden through an expanding economy, telling an audience at Southern Methodist University last month that achieving 3% growth will resolve the trajectory.
