IMF Pulls Forward Global Debt-to-GDP Forecast to 100% by 2029, Warns of 'Structural' Fiscal Pressure
The IMF's April 2026 Fiscal Monitor argues that the Middle East war is hitting public finances already weakened by structural deficits. Global gross public debt reached 94% of GDP in 2025, interest spending has climbed from 2% to nearly 3% of GDP in four years, and the Fund now projects debt will cross 100% of GDP by 2029 — one year earlier than its 2025 forecast.

The International Monetary Fund's April 2026 Fiscal Monitor — released April 15 at the Fund's Spring Meetings — pulls its global gross-debt-to-GDP projection forward by a year and argues that today's fiscal pressures are structural rather than cyclical.
The report, Fiscal Policy under Pressure: High Debt, Rising Risks, frames the fiscal consequences of the Middle East war against a starting position that was already weak.
The numbers
| Indicator | 2025 value | Change or projection |
|---|---|---|
| Global fiscal deficit | 5.0% of GDP | Unchanged from 2024 |
| Global gross public debt | 94% of GDP | Projected to reach 100% by 2029 (one year earlier than the April 2025 forecast) |
| Global interest spending | ~3% of GDP | Up from 2% four years ago |
| US general government deficit | 7–8% of GDP | No consolidation plan announced |
| US gross public debt | — | Projected to reach 142% of GDP by 2031 |
| Global debt-at-risk (95th percentile, 3 years ahead) | 117% of GDP | Reference scenario |
| Global debt-at-risk — severe scenario | >120% of GDP | Oil +100% above WEO baseline, 2027 |
"Debt-at-risk" is the IMF's tail-risk measure — the 95th percentile of the projected debt distribution three years ahead. The severe scenario's increase is "concentrated in emerging market and developing economies," the blog accompanying the report notes.
The structural argument
The Fund's central claim is that fiscal weakness has changed character since the pandemic:
Weaknesses are no longer mainly cyclical or the result of temporary emergencies, but are structural: security spending, climate and energy transition costs, and rising interest bills are placing persistent demands on budgets, while revenues have not kept pace.
Three recent shocks — the pandemic, the 2022 energy/food price spike, and rising trade disruptions — "left governments with higher debt, weaker buffers, and delayed adjustment." Even with robust 2025 global growth, the IMF notes, "there was no meaningful progress in repairing budgets. In many countries, deficits stayed high, debt kept rising, and interest bills grew rapidly."
What the Fund is telling governments to do
The IMF's policy recommendations stack five specific instructions:
- Keep energy/food support targeted and temporary. Use pandemic-era safety nets rather than broad subsidies. Broad fuel subsidies are called out as "costly, poorly targeted, difficult to reverse, and encourage higher consumption when supply is constrained."
- Reallocate rather than borrow. Countries with narrow fiscal space should "reallocate spending within the same limits" instead of financing crisis support with fresh debt.
- Coordinate with monetary policy. Emergency spending shouldn't "create new aggregate demand" — the IMF's framing for keeping fiscal response compatible with central bank disinflation.
- Commit to medium-term consolidation with concrete measures. "Not distant or shifting targets."
- Broaden the tax base. "Streamlining exemptions, and strengthening tax administration can raise revenues even in constrained settings."
Other risks flagged
Beyond the war, the report lists:
- Trade and financial fragmentation lowering growth and raising financing costs
- Political instability weakening reform and revenue collection
- "Abrupt repricing in markets, including in now dominant AI stocks" that could tighten financial conditions
- Central-bank balance-sheet runoff shifting the marginal sovereign-debt buyer toward price-sensitive private investors, making borrowing costs "more sensitive to shifts in market sentiment"
That last point echoes the April 2026 Global Financial Stability Report released one day earlier, which made the same structural observation about a changing investor base as part of its nonbank-amplification argument.
Why the pull-forward matters
The one-year acceleration in the global debt-to-GDP trajectory — from the April 2025 Fiscal Monitor projection of 100% in 2030 to the April 2026 projection of 100% in 2029 — is the cleanest summary of what the Fund is arguing: the world isn't absorbing shocks and returning to trend, it's compounding them.
