Interest Costs Turn U.S. Debt Into a Fiscal Time Bomb
The cost of servicing U.S. debt has entered a new and dangerous phase. According to data from the U.S. Treasury, interest payments made to overseas holders of U.S. public debt surged to a record $292 billion in the third quarter of 2025.
Key Takeaways
- Interest paid to foreign holders of U.S. debt has more than doubled since 2020, hitting record levels in 2025.
- Total U.S. debt has surged past $38 trillion, pushing interest costs to nearly $1 trillion per year.
- The government now spends close to $3 billion per day just to service its debt.
That figure has more than doubled since 2020 and is now six times higher than what Washington paid foreign creditors before the 2008 financial crisis.
This surge is not just the result of higher interest rates. It also reflects the massive expansion of total borrowing over the past decade, which has sharply amplified the government’s sensitivity to even small rate increases.
A Debt Pile Growing at Record Speed
Total U.S. national debt reached $38.63 trillion as of February 7, 2026, rising at an average pace of roughly $1 trillion every 100 days. Analysis from the Bipartisan Policy Center shows that interest payments have now become the second-largest federal expense, trailing only Social Security and overtaking defense and healthcare spending.
This marks a structural shift in the federal budget, where borrowing costs themselves are now crowding out other priorities rather than supporting them.
The Trillion-Dollar Interest Era
The U.S. is entering what analysts increasingly call the “trillion-dollar interest” era. Annual interest payments are projected to exceed $1 trillion in 2026 for the first time in history, nearly three times the roughly $345 billion paid in 2020. On a daily basis, the government is now spending about $2.9 billion simply to service existing debt.
Net interest costs are expected to reach around 3.2% of GDP this year, surpassing the previous all-time high set in the early 1990s and highlighting how debt dynamics have become a macroeconomic risk.
Foreign Creditors Still Matter
Foreign investors remain deeply embedded in the U.S. debt market. Overseas holders owned a record $9.4 trillion in U.S. Treasuries as of late 2025. Japan remains the largest foreign holder at around $1.2 trillion, while China has reduced its holdings to approximately $682 billion, down sharply from its 2013 peak.
Even though the share of U.S. debt held by foreigners has declined to about 30% from nearly 50% in the early 2010s, the absolute dollar exposure has continued to climb, intensifying the interest outflows leaving the country.
Budget Pressure Is Reaching Extremes
Key fiscal indicators underline how strained the system has become. The U.S. debt-to-GDP ratio is hovering near 124%, with some real-time trackers placing it even higher. The average interest rate on marketable federal debt has risen to about 3.35%, more than double its level five years ago.
Most concerning for policymakers, interest payments now consume roughly 22% of total federal revenues, far above the 50-year average of around 12%. With borrowing costs accelerating faster than revenues, interest is no longer a background issue – it is becoming one of the defining constraints on U.S. fiscal policy in 2026.
