The IMF lifted its 2026 world growth forecast to 3.1%, but says only 32 economies are doing most of the growing

The International Monetary Fund nudged up its forecast for the world economy on Tuesday, October 13. It also warned that the resilience behind the upgrade is unevenly shared and getting thin. In its October 2026 World Economic Outlook, released at the IMF and World Bank Annual Meetings in Bangkok, the fund projected global growth of 3.1% this year. That is up from 3.0% in its July update and down from 3.5% in 2025. It expects growth to pick back up to 3.4% in 2027.

The report, titled "Resilience Under Strain, Urgent Choices," according to Xinhua, describes a world economy pulled in two directions. An energy shock tied to the Iran war and the disruption of shipping through the Strait of Hormuz is weighing on growth and lifting prices. At the same time, heavy investment in artificial intelligence is propping up demand and trade in a small group of economies. "The outlook is highly uneven," IMF deputy research director Silvana Tenreyro said, as quoted by the Associated Press via Fortune.

What does the IMF forecast for 2026 and 2027?

The headline global number barely moved, but the picture underneath shifted. The IMF expects advanced economies to grow 2.1% this year. Emerging market and developing economies are forecast to slow sharply, from 4.5% in 2025 to 3.7% in 2026, before rebounding to 4.4% in 2027.

The United States is projected to grow 2.3% in both years. MASEconomics reports that the IMF credits consumer spending, fiscal policy and technology investment. China's forecast of 4.5% for 2026 matches Beijing's official target. India remains the fastest-growing major economy at 7%. The euro area is expected to manage just over 1%, with Germany at 1.3% and France at 0.4% this year. Japan is at 0.7%.

The sharpest downgrades are in the Gulf. The Middle East and Central Asia region is forecast to shrink this year before a strong rebound in 2027. Xinhua reported that Saudi Arabia's 2026 forecast was cut by 5 percentage points from July, to a 3.3% contraction. Bahrain, Iraq, Kuwait and Qatar are expected to shrink by double digits.

Why are energy prices and the Strait of Hormuz so central?

Before the war, the Strait of Hormuz carried about a quarter of the world's seaborne oil trade, Xinhua noted. The IMF's baseline now assumes shipping through the strait resumes in March 2027, with conditions close to prewar levels by October 2027. If that reopening slips, the expected 2027 rebound slips with it.

The fund assumes oil averages about $95.74 a barrel in 2026, roughly 41% above last year, before easing to about $87.39 in 2027. SDG News reports the IMF also expects fertilizer prices to rise about 10% and food prices about 5% this year. The IMF estimates the strait's closure would have cut global growth by about 0.9 percentage point this year if nothing had offset it. Supply responses elsewhere reduced the net hit to about 0.3 point.

That is why the IMF raised its inflation outlook even as it lifted growth slightly. Global headline inflation is now forecast at 4.7% in 2026, up from 4.1% in 2025, before easing back to 4.1% in 2027. Core inflation is not expected to return to 2% until the end of 2027 in Japan and Britain, and mid-2028 in the euro area and the United States.

How is AI investment changing the global outlook?

The IMF says AI spending is one of the main reasons growth held up better than expected. Investment in chips, data centers and cloud systems is supporting demand and trade. It is also raising demand for electricity, grid connections, cooling, construction and skilled labor. But the gains are concentrated. According to the Associated Press, the United States and China account for more than three-quarters of net demand for imports of AI-related chips and equipment.

The concentration shows up in the growth numbers too. Just 32 economies now account for 95% of global growth, down from 54 in April. Technology exporters are booming. MASEconomics reports the IMF forecasts Taiwan's economy to grow 10.7% this year, and South Korea's 3.3%, up from 1.1% in 2025. About 47% of economies had their growth forecasts cut compared with April, SDG News reported.

The AI boom is also a risk. The IMF flagged the possibility of an AI-related stock market correction. Markets got a taste of that the same day the report came out: South Korea's Kospi fell as much as 7% on Tuesday and closed 5.5% lower amid a sell-off in AI shares, the AP reported. IMF Managing Director Kristalina Georgieva has estimated that AI will affect about 40% of jobs worldwide over time, through augmentation, downgrading or elimination.

What risks does the IMF see for the world economy?

The fund says risks are tilted to the downside. Its main concerns:

• A longer war. A prolonged conflict would push energy and food prices higher again. In an adverse scenario with oil at $130 a barrel from late 2026 into early 2027, global growth in 2027 would be about 0.5 point below the baseline and inflation about 1.1 points higher, according to SDG News.
• Persistent inflation. The IMF puts the chance of global inflation exceeding 5% in 2027 at about 35%, up from 30% in April. It sees about a 10% chance that global growth falls below 2% next year.
• Debt. Public debt in advanced economies is projected to rise from 108% of GDP in 2025 to 115% by 2031. In emerging and developing economies it rises from 74% to 84%.
• Markets and trade. Rising bond yields, renewed trade tensions and cyberthreats to the financial system round out the list.

On policy, the IMF favors temporary, targeted income support for vulnerable households over price caps and subsidies, which its simulations suggest can cost three to 22 times as much for similar protection. It also encourages broader trade relationships, diversified energy supply and stockpiles of essential inputs. It cautions that reshoring production can be inefficient and can concentrate risk at home.

What it means for businesses

For companies that import, export or borrow, the report points to a few practical themes. Energy and freight costs are likely to stay elevated at least until shipping through Hormuz normalizes, and the IMF's own timeline runs well into 2027. Inflation above central bank targets makes quick, deep rate cuts less likely in major economies. Demand is strongest in markets tied to the AI build-out and weakest in energy-importing economies outside it. Businesses weighing new markets, supplier changes or financing may want to stress-test their plans against the IMF's higher-oil scenario and talk with financial advisors about rate exposure.

What to watch next

The Annual Meetings continue in Bangkok this week, with finance ministers and central bank governors from the IMF's 191 member countries discussing debt, energy and trade. The fund's next full forecast update is due in January. Before then, the key signals will be oil prices, the timing of any reopening of the Strait of Hormuz, inflation readings in the major economies, and whether the selling in AI-linked stocks seen in Seoul this week spreads further.
