Global Debt Nears 100% of GDP, IMF Warns of Crisis

Washington, D.C., April 15, 2026 — The International Monetary Fund said global public debt is on track to climb to 99% of world GDP by 2028, and that the world could cross the 100% mark sooner than it had previously projected. The warning was delivered at the spring launch of the IMF’s twice-yearly Fiscal Monitor in Washington, D.C.

The IMF described the outlook as a structural challenge, with public finances under strain across many countries. It said ongoing geopolitical events are adding to the pressure, complicating efforts to rebuild fiscal buffers and manage rising financing needs.

Rodrigo Valdes, Director of the IMF Fiscal Affairs Department, pointed to the United States as a major driver of the global debt trajectory. He cited U.S. national debt at $39 trillion and said the U.S. deficit, after a temporary narrowing, is expected to move back to about 7.5% of GDP and stay around that level.

In the IMF’s projections, U.S. debt is expected to exceed 125% of GDP this year and could reach 142% by 2031. The IMF said stabilizing the path would require fiscal tightening of about 4 percentage points of GDP, which it characterized as a large adjustment.

Beyond the U.S., the IMF said the “fiscal gap” has deteriorated by roughly one percentage point compared with pre-COVID levels. It defined the fiscal gap as the difference between current primary balances and the balances needed to stabilize debt, indicating that more countries now face a larger policy effort to prevent debt ratios from rising further.

The IMF also highlighted the role of financing conditions. It said real interest rates are now about 6 percentage points higher than before the pandemic, increasing the cost of carrying existing debt and making debt dynamics more sensitive to shifts in growth and borrowing costs.

On near-term pressures, the IMF said the Middle East conflict is adding fiscal strain. It cautioned governments against broad energy subsidies, arguing that such measures can be costly, and instead recommended targeted support for vulnerable populations.

The IMF also flagged artificial intelligence as a potential wildcard for public finances. It said AI could help raise government productivity, strengthen tax administration, and improve the delivery of public services, while also posing risks tied to wealth concentration and disruption in labor markets.
