The International Monetary Fund’s latest outlook offers a deceptively reassuring headline: global output is expected to grow 3.1% in 2026, a slight improvement on the fund’s previous forecast. But beneath that upgrade is a more consequential story—growth is becoming increasingly concentrated, while war and energy disruption are pushing inflation and debt risks back to the centre of economic policymaking.

The IMF expects global growth to slow from 3.5% in 2025 to 3.1% this year, before reaching 3.4% in 2027. Global inflation, however, is projected to rise to 4.7% in 2026 before easing to 4.1% next year. The combination suggests that resilience is real but fragile: economies are still expanding, yet households and governments face renewed pressure from prices and borrowing costs. France 24 reported the IMF’s warning that war and debt could threaten the outlook.

Why the forecast improved

Several forces have kept activity stronger than expected. Investment linked to artificial intelligence has supported demand for semiconductors, data centres and advanced infrastructure. Taiwan and South Korea, both deeply integrated into the technology supply chain, are expected to outperform many other advanced economies. The United States is forecast to grow 2.1% in 2026, while advanced economies as a group are projected to expand 2.1%.

That performance has helped offset weakness elsewhere. The IMF’s assessment, as summarized by Fortune, is that only 32 countries account for roughly 95% of global growth. The figure captures the central tension in the current cycle: headline expansion can remain respectable even as many individual economies experience stagnation, falling living standards or sharply higher fiscal risks.

AI investment is also changing the composition of growth. Supporters argue that spending on computing capacity and automation could raise productivity and eventually broaden prosperity. Yet the near-term benefits are concentrated among firms, workers and countries able to supply capital, chips, software and electricity. The IMF has warned that the financial enthusiasm surrounding AI could itself become a vulnerability if valuations outrun earnings or investment returns.

War turns resilience into a test

The sharpest threat comes from the conflict involving the United States and Iran, which has disrupted energy markets and contributed to a steep rise in oil prices. The IMF’s forecasts assume average oil prices of about $96 a barrel in 2026—roughly 41% higher than the previous year, according to Fortune.

The effects are uneven. Energy exporters may receive a short-term revenue boost, while import-dependent states face higher transport, electricity and food costs. Refined petroleum products remain far above pre-war levels, putting particular strain on low-income economies with limited fiscal room. The Middle East and Central Asia region is expected to contract 0.3% in 2026, after a substantial downward revision linked to the conflict and disruption around the Strait of Hormuz. Anadolu Agency reported that the region suffered the largest regional downgrade in the IMF’s outlook.

There is a legitimate debate over how persistent the shock will be. If hostilities ease and shipping routes reopen, energy prices could fall and inflation could resume its decline. If the conflict becomes prolonged, the impact would spread through freight, food production, public finances and central-bank decisions. The IMF’s projections therefore describe not only an economic baseline but also a narrow path that depends on geopolitical containment.

The developing-world squeeze

Emerging and developing economies are projected to grow 3.7% in 2026, down from 4.5% in 2025. China’s growth forecast has been lowered to 4.5%, while nearly half of economies have reportedly received downward revisions compared with earlier estimates. Higher energy bills are only part of the problem: elevated interest rates and a strong demand for safe assets make it more expensive for heavily indebted governments to refinance.

Those pressures complicate the policy response. Subsidies can shield consumers from fuel-price spikes but worsen budget deficits. Allowing prices to pass through protects public finances but risks poverty and political unrest. Cutting interest rates may support activity, yet doing so while inflation is rising can weaken currencies and increase imported costs.

Advanced economies also face constraints, though their buffers are larger. Governments must finance defence, energy security, industrial policy and climate adaptation while debt-service costs remain high. Their relative resilience should not be mistaken for immunity: persistent inflation could delay monetary easing, while a correction in technology investment could expose the narrowness of current growth.

What comes next

The next phase will be defined by whether investment-led growth broadens beyond the technology sector and whether energy disruption fades. A benign outcome would combine lower oil prices, gradual disinflation and productivity gains from AI. A harsher one would involve renewed energy inflation, weaker trade, higher borrowing costs and widening divergence between countries.

Policymakers face a choice between treating the IMF upgrade as evidence that the world economy can absorb repeated shocks or using it as a warning that the margin for error is shrinking. The evidence supports both interpretations. Growth has endured—but increasingly through concentrated engines that cannot indefinitely compensate for war, debt and unequal access to investment.
