   US Debt Interest Costs Hit $3 Billion a Day as Deficit Nears $2 Trillion

   Daily interest payments on the United States national debt reached $3 billion during fiscal year 2026, driven by an 8% increase in net interest costs to $1.05 trillion. Treasury Department data shows the federal budget deficit expanded by 12% in a single year to $1.99 trillion, marking the largest budget gap in five years. Federal revenue rose 3% to $5.4 trillion, which was outpaced by a 6% increase in spending to $7.4 trillion. Interest payments on the debt now rank as the third-largest federal budget item, surpassing both defense spending and Medicaid.

   Why it matters

   The widening fiscal gap presents a major test for federal policymakers as the 2026 midterm elections approach. Interest costs grew faster than total federal spending, government revenue, and gross domestic product over the past year. The average interest rate on the debt climbed to 3.53%, more than double the rate recorded in 2021 before the Federal Reserve initiated its aggressive monetary tightening cycle.

   What is confirmed

   • Net interest payments on the national debt rose 8% to $1.05 trillion in fiscal year 2026.
   • The federal budget deficit widened to $1.99 trillion for fiscal year 2026, up 12% from the $1.78 trillion gap in fiscal 2025.
   • Federal revenue increased 3% to $5.4 trillion while spending grew 6% to $7.4 trillion.
   • Gross interest costs for fiscal 2026 reached $1.36 trillion with an average interest rate of 3.53%.
   • Interest payments on the national debt ranked third behind Social Security and Medicare, surpassing defense spending and Medicaid.

   Still unconfirmed

   • Critics warn that the trajectory of debt interest costs risks creating a debt snowball.

   What to watch next

   • Polling numbers and voter sentiment regarding fiscal policy ahead of the November 2026 midterm elections.
   • Future Federal Reserve interest rate adjustments that could impact the average 3.53% debt interest rate.
