IMF Raises 2026 Global Growth Forecast to 3.1%

The International Monetary Fund raised its forecast for global economic growth in 2026 to 3.1 percent on Tuesday, a modest upgrade of 0.1 percentage point from its July projection, as an artificial-intelligence investment boom offset the drag of conflict in the Middle East for some economies. The fund released the findings in its October World Economic Outlook during the IMF-World Bank Group Annual Meetings in Bangkok, Thailand, which run from October 12 to 18.

The headline figure, however, conceals a markedly strained and divergent global picture. Growth is expected to slow from an estimated 3.5 percent in 2025 to 3.1 percent this year before recovering to 3.4 percent in 2027, according to Xinhua, which reported the release from Bangkok.

An Upgrade Built on Divergence

The IMF said the AI investment boom—its boost to some economies—had offset the drag on others from the Middle East conflict. Global growth, it noted, has diverged as countries were affected to different degrees by war-induced energy shocks and AI-related demand. The economies faring best combined resilient energy supply with close links to the AI hardware supply chain.

By contrast, many energy-importing countries not closely tied to the technology cycle faced higher import costs, weaker currencies, and falling real incomes.

The split is visible in the fund’s regional numbers. Advanced economies were upgraded sharply, with 2026 growth now projected at 2.1 percent, up 0.4 percentage point from July. Emerging market and developing economies, meanwhile, saw a 0.1-point downgrade to 3.7 percent.

The report—titled “Resilience under Strain, Urgent Choices”—was published on schedule, though the fund’s official October 2026 page still showed the full Chapter 1 narrative as forthcoming at the time of release, with analytical chapters having been published on October 5 and 6.

The Gulf Bears the Brunt

The most severe downgrades were concentrated in the Gulf, where the disruption of shipping through the Strait of Hormuz has throttled energy production and transport.

Saudi Arabia’s economy is now projected to contract 3.3 percent in 2026—a downgrade of a full 5 percentage points from July. Bahrain, Iraq, Kuwait, and Qatar, commodity producers hit hard by interruptions to energy output and transportation, are expected to post double-digit contractions this year.

The IMF estimated that obstruction of shipping through Hormuz could shave 0.9 percentage point off global growth in 2026. That net impact is slightly cushioned by the rerouting of Gulf oil exports, higher crude output elsewhere, and releases from strategic petroleum reserves.

In the major advanced economies, the United States is forecast to grow 2.3 percent in both 2026 and 2027, supported by consumption, fiscal policy, and technology investment. The euro area is expected to expand 1.1 percent this year and 1.2 percent in 2027, reflecting persistent drag from high energy prices and weak consumer confidence.

Inflation’s Comeback and an Oil Warning

The fund flagged two pressures that could test its cautiously optimistic baseline. Global headline inflation is forecast to rise from 4.1 percent in 2025 to 4.7 percent in 2026 before easing back to 4.1 percent in 2027—a renewed upward path that complicates the calculus for central banks.

Oil prices are a central reason. The IMF estimated the 2026 average oil price at US$95.74 per barrel, roughly 41 percent above 2025 levels.

The fund also issued a pointed warning: global oil inventories are sliding toward warning levels that could trigger a sharp price surge. That caution echoes the theme running through the IMF’s 2026 forecast cycle, in which a war-driven energy shock has weighed on energy importers while an AI and technology upcycle has lifted economies plugged into the global tech value chain.

A Forecast in Crosscurrents

The October report completes a volatile forecasting year for the fund. In January, it had projected 3.3 percent global growth for 2026. Its April outlook, subtitled “Global Economy in the Shadow of War,” downgraded growth amid renewed inflation driven by the Iran-Hormuz oil shock. By its July update—“Global Economy in Crosscurrents of War and Technology”—the fund had cut 2026 growth to 3.0 percent while holding 2027 at 3.4 percent, describing an outlook that was steady but uneven. The latest edition restores a tenth of a point to the 2026 number without changing the 2027 trajectory.

What to Watch

The upgrade offers only cautious optimism. The defining feature of the IMF’s latest outlook is not the higher headline number but the widening gap between the winners and losers of a world shaped simultaneously by war and technological transformation.

Three questions will determine whether the fund’s baseline holds. First, whether the AI investment cycle can keep offsetting conflict-driven energy costs if the technology spending wave cools. Second, whether oil inventories can be replenished before a price spike feeds through to consumer inflation, which is already forecast to climb. And third, whether the Gulf contractions deepen further, given that the Hormuz disruption remains the single largest downside risk in the fund’s projections.

For now, the IMF’s message is one of resilience—but resilience under strain, and requiring choices that policymakers in Bangkok this week will be pressed to make.
