The revised outlook, released at the IMF and World Bank annual meetings in Bangkok this week, is up from the 3% projected in July but still below the 3.5% growth recorded last year. The fund left its 2027 forecast unchanged at 3.4%.
The IMF said AI-related investment gave the global economy a "demand impulse" that helped activity in the first half of the year hold up better than expected despite the war and ongoing trade tensions. Financial markets have also stayed largely calm, which the fund said may partly reflect "AI-related exuberance."
"Use of buffers and adaptability have helped economies weather the negative shocks," the IMF said, citing measures such as diversifying fuel sources and tapping strategic reserves to contain the energy-market turmoil from the conflict.
But that cushion is "rapidly narrowing." Global oil reserves are being drawn down by about 2.7 million barrels a day, nearing levels the fund says could trigger sharp price moves, and energy constraints could impair the AI-led momentum. The IMF now estimates the Strait of Hormuz will reopen in March next year and return to its pre-war state by October. Gulf crude exports averaged 88% of pre-conflict levels in September.
On inflation, the fund kept its current-year outlook at 4.7% but raised its 2027 projection to 4.1%, above the 3.9% it expected in July.
Growth is becoming increasingly uneven. Thirty-two economies now account for 95% of global growth, down from 54 in April. Countries catering to AI-led demand are strengthening, with Taiwan forecast to grow 10.7% this year and South Korea 3.3%, lifted by semiconductor demand. The United States is projected to expand 2.3% in both 2026 and 2027.
