The Treasury Department reported that the federal budget deficit widened to $1.99 trillion for fiscal year 2026, a 12% increase from the $1.78 trillion shortfall recorded in fiscal 2025. While revenue grew 3% to $5.4 trillion, spending rose 6% to $7.4 trillion, leaving interest payments on the national debt as the third‑largest line item, ahead of defense spending and Medicaid.
Interest costs outpace the economy
Gross interest outlays for the year reached $1.36 trillion, reflecting an average interest rate of 3.53%, more than double the rate seen in 2021 before the Federal Reserve’s aggressive tightening cycle. Net interest payments—what the government actually pays after accounting for interest received—climbed 8% to $1.05 trillion. At that level, interest expenses translate to roughly $2.9 billion a day, surpassing the growth rates of total spending, revenue and gross domestic product.
Real GDP grew about 2% in the period, while nominal GDP rose about 6%. The Peter G. Peterson Foundation estimated that net interest costs now represent 3.2% of GDP, breaking the previous record set in 1991.
Debt structure and market pressures
With gross U.S. debt at $40 trillion and publicly held debt equal to 100% of GDP, the Treasury is increasingly dependent on short‑term borrowing. Treasury Secretary Scott Bessent has been issuing more short‑term debt while retiring longer‑term obligations. Approximately one‑third of publicly held debt—over $10 trillion—is scheduled to mature within the next 12 months, meaning the government must refinance that amount at today’s higher rates.
The Congressional Budget Office (CBO) projects annual debt‑interest expenses to reach $2.1 trillion by 2036. However, the 10‑year Treasury yield has climbed above 5%, outpacing the CBO’s forecasts of 4.1% for this year and a gradual rise to 4.4% by 2036. The Committee for a Responsible Federal Budget (CRFB) warns that if yields remain about one percentage point above the CBO’s estimates, interest costs could surge to $2.8 trillion—5.9% of GDP—by the end of the decade.
Policy debate and economic outlook
CRFB President Maya MacGuineas warned that “higher interest begets more debt, and greater debt begets higher rates,” urging immediate fiscal intervention. Treasury Secretary Bessent argued that a 3% economic growth rate could help the nation “grow its way out of this,” citing a strong underlying economy.
CBO Director Phillip Swagel countered that relying on growth alone is unlikely to stabilize debt. He noted that while stronger growth can boost revenue, it also raises wages, which increase outlays for Social Security and Medicare, and tends to lift interest rates. Swagel estimated that nominal GDP would need to grow 7%‑8% and real GDP 5%‑6%—more than double the recent 2.2% real‑growth pace—to offset rising interest costs under 4%‑5% interest‑rate scenarios.
Current Wall Street forecasts anticipate full‑year GDP growth of about 2.5%, far short of Swagel’s thresholds. Meanwhile, political signals have not indicated a willingness to address spending or revenue. President Donald Trump has called for a $5,000 “dividend” check for Americans if Republicans win the midterm elections and is providing rebates to millions of Medicare and Affordable Care Act enrollees, but no substantive fiscal reforms have been announced.
As interest payments become the fastest‑growing component of the federal budget, policymakers face a narrowing window to curb the debt trajectory before market volatility further amplifies borrowing costs.
