IMF: AI Investment Sustains Global Growth, but War and Debt Pose Rising Risks

The International Monetary Fund released its latest economic forecast this week in Bangkok, and the picture it painted was one of stubborn resilience shadowed by gathering storms. Global growth will reach 3.1% in 2026, the fund announced, a modest upgrade from its July prediction of 3.0%. The reason for the improvement is straightforward: artificial intelligence. Investment in AI infrastructure has proven robust enough to offset the economic drag from a prolonged conflict in the Middle East that has kept oil prices above $100 a barrel. Yet beneath this headline number lies a more troubling reality—one that reveals how unevenly the benefits of growth are being distributed, and how fragile the foundation supporting that growth has become.

The IMF's chief economist, Silvana Tenreyro, framed the situation plainly: the global economy remains resilient, but that resilience is under strain. The risks, she said, are tilted toward the downside. A prolonged Middle East conflict could intensify inflation and slow growth. Fiscal troubles, a reassessment of whether AI investments will actually pay off, and extreme weather could all weaken the outlook further. The fund is forecasting 3.4% growth for 2027, unchanged from July, but that stability masks significant uncertainty about what comes next.

The most striking finding in the IMF report concerns the concentration of growth. Just 32 countries now account for 95% of global growth, compared to 54 countries in April. This dramatic narrowing reflects which nations are positioned to benefit from the AI boom. Advanced economies building AI platforms, and countries supplying the hardware those platforms require—South Korea, Malaysia, Mexico, and Thailand among them—have seen their growth forecasts upgraded. Everyone else is falling further behind. The IMF downgraded growth forecasts for 47% of all economies since April, with the hardest hits landing on countries outside the AI value chain, particularly energy importers.

The Middle East has been devastated by the conflict. Saudi Arabia's economy, which the IMF predicted would grow 1.7% in July, is now forecast to contract 3.3% this year. Iran, Iraq, Kuwait, Qatar, and the United Arab Emirates face even steeper declines—contractions ranging from 3.9% to 16.7%. These are not marginal adjustments. They represent a fundamental reshaping of economic prospects for some of the world's largest oil producers and most strategically important regions. The IMF's baseline assumption is that the Strait of Hormuz will reopen in March 2027 and shipping will return to normal by October 2027. But that is an assumption, not a certainty.

Among the world's largest economies, the picture is mixed. The United States is expected to grow 2.3% in both 2026 and 2027, supported by strong consumer spending, tax cuts, and AI investment, though the boost from AI will be partially offset by the high import content of those investments. The eurozone has been upgraded to 1.1% growth for 2026, up from 0.9%, thanks to stronger AI investment and higher defense spending. Britain's forecast rose to 1.3%. China, meanwhile, is expected to grow 4.5% this year and 4.0% next year, both down slightly from July as higher oil prices weigh on an economy already struggling with weak domestic demand. India remains the world's fastest-growing major economy, with growth forecast at 7.0% for both years, upgraded from earlier predictions.

The IMF has identified two major sources of downside risk that could unravel this forecast. The first is energy. If the Middle East conflict worsens and oil prices spike to $130 per barrel through the first quarter of 2027, global growth would be reduced by 0.2 percentage point in 2026 and 0.5 percentage point in 2027. Inflation in 2027 would surge by an additional 1.1 percentage point to 5.2%. The second risk is AI itself. If productivity gains from artificial intelligence fail to materialize and investment collapses, the consequences would be severe. US GDP could fall by 0.8% directly, with spillovers to Asian technology exporters adding another 0.4% in losses by 2028. A sharp reduction in asset prices and tighter financial conditions would trigger a major drop in consumption, particularly in the United States. Higher global bond yields would further reduce economic activity, with a combined global output reduction of 1.1% by 2028 and a 1.8% drop in US output.

Underlying all of this is the problem of debt. The IMF warned that elevated public debt levels, particularly in advanced economies, increase the risk of sharply higher borrowing costs that can weigh on growth prospects. The fund urged governments to stop delaying action to rebuild fiscal buffers and articulate credible plans to bring debt back to sustainable levels. This is the advice IMF officials plan to push at the Bangkok meetings, but it is also a warning: the world has less room to maneuver than it appears. AI investment is holding up growth, but only for those countries positioned to capture it. The Middle East conflict is manageable for now, but only if it does not worsen. And debt levels are sustainable only if growth continues and interest rates do not spike. Remove any one of these supports, and the entire structure becomes precarious.
