Can America Inflate Its Way Out? US Debt, Interest Costs and the Case for a Weaker Dollar
The US federal debt story is no longer about a distant 2030 problem; it is already reshaping policy today. By late 2025, total federal debt stood around 38–38.5 trillion, roughly 125% of GDP. With nominal GDP near 29–30 trillion, debt now exceeds output by a wide margin. That ratio is projected to keep grinding higher in 2026 and beyond.
Tax revenue has not kept pace. Federal receipts have hovered around 20–21% of GDP in recent years, implying roughly 5.8–6.2 trillion of annual tax income on today’s GDP base. Against that revenue, interest costs have exploded. For fiscal year 2025, net interest outlays were close to 1.0–1.2 trillion, and recent estimates show the Treasury now paying over 90 billion a month in interest. That puts interest at roughly 16–20% of federal tax revenue—before a single dollar is spent on defense, healthcare or Social Security.
This is where sustainability meets politics. Mathematically, there are only three levers:
- Run large primary surpluses (spending cuts and tax hikes).
- Grow nominal GDP faster than debt.
- Or let inflation and negative real rates steadily erode the burden.
The first option is politically toxic. The second requires robust growth plus discipline that Washington has not shown in decades. That leaves the third path—financial repression via low real rates and a gently weaker dollar—as the path of least resistance.
A softer dollar helps in two ways. It boosts nominal GDP through exports and higher dollar prices, and it quietly reduces the real value of outstanding debt held by both foreign and domestic investors. For long‑term investors, this “debasement as base case” is exactly why assets like gold, real resources and non‑US equities deserve a structural place in portfolios.
