IMF Lifts 2026 Growth Forecast to 3.1% as the AI Boom Offsets the Energy Shock

The International Monetary Fund nudged up its outlook for the world economy this week, while warning that the picture beneath the headline number is increasingly uneven. In its October World Economic Outlook, titled “Resilience Under Strain, Urgent Choices,” the Fund expects global output to grow 3.1% in 2026, up 0.1 percentage point from its July forecast, before accelerating to 3.4% in 2027. Growth in 2025 is estimated at 3.5%.

A Two-Speed Economy

The IMF’s central argument is that the global economy is neither simply slowing nor speeding up. Instead, growth is being reallocated according to how exposed each country is to two forces: the energy shock stemming from the war involving Iran, and the surge in spending on artificial intelligence. Economies lifted by the AI investment boom are helping to offset the drag on those hit hardest by costlier fuel.

Advanced economies are projected to expand 2.1% this year and 1.8% in 2027. Emerging market and developing economies are forecast to slow to 3.7% in 2026 before rebounding to 4.4% next year. Among the largest economies, the United States is projected to grow 2.3% in both 2026 and 2027, while China’s expansion is expected to ease to 4.5% this year and 4.0% in 2027, largely because of weak domestic demand. The United Kingdom’s 2026 forecast was raised to 1.3%, though its 2027 outlook was trimmed to 1.2%.

Inflation Moves the Wrong Way

Prices are the less comfortable part of the report. The Fund expects global headline inflation to climb from 4.1% in 2025 to 4.7% in 2026 before easing back to 4.1% in 2027. That path helps explain why central banks have had little room to cut interest rates, and why the U.S. Federal Reserve has instead raised them.

AI as an Engine of Growth

Speaking at the IMF and World Bank annual meetings in Bangkok, Managing Director Kristalina Georgieva said accelerating investment in AI infrastructure is one of the main reasons global growth is holding near 3%. The Fund also credited changes in energy supply routes, higher output in some producing countries, and a shift toward alternative energy for the economy’s resilience through a series of shocks.

The flip side, as many analysts point out, is concentration. A world economy leaning heavily on one investment theme is more exposed if that theme disappoints, and the report’s title hints at the same tension between resilience and strain.

What to Watch

Three variables will decide whether the forecast holds: how much oil actually flows through the Strait of Hormuz, whether AI-related spending keeps expanding, and whether inflation cools fast enough to let policymakers ease. The next IMF update is due in January.
