Exploding Debt Service Costs
Key Questions
What are the projected U.S. debt service costs for FY2026?
CBO estimates show daily interest costs of about $3 billion on $39-40 trillion in debt, totaling $1.22-1.28 trillion annually or over 4% of GDP. This exceeds spending on Medicare, Medicaid, and defense.
How do tariffs factor into the debt outlook?
Tariffs could generate roughly $94 billion in deficit reduction but are projected to leave cumulative deficits of $1.9 trillion in FY2026 and $3.1 trillion by 2036.
Why are foreign holders selling U.S. Treasuries?
Japan has already sold $54 billion in Treasuries, with China also reducing holdings amid sticky inflation and expectations of no near-term Fed cuts. This adds pressure to yields and mortgage rates.
What warnings have investors issued about debt levels?
Dalio, Dimon, Buffett, and Musk have highlighted risks of Japanification, while Zandi has flagged inflation concerns if debt service crowds out other spending.
How does the per-household debt service burden compare to historical levels?
Annual interest costs now equate to roughly $18,000 per U.S. household, surpassing $1 trillion yearly and exceeding 4% of GDP for the first time in decades.
