Global economy to slow less than expected in 2026 as AI boom offsets war hit: IMF

The IMF raised its 2026 global growth forecast to 3.1% (from 3.0%) as AI-related investment supports demand, even as it expects inflation to be higher this year and notes buffers are narrowing as energy stockpiles are drawn down.

The IMF said the global economy will slow, but less than it previously expected, raising its 2026 growth forecast to 3.1% from a July projection of 3.0%. Growth is expected to ease to 3.4% in 2027. The IMF’s framing is that AI-related investment has provided a “demand impulse” that helped activity hold up better in the first half of the year despite the Middle East war and trade tensions.

On inflation, the IMF maintained a 4.7% outlook for 2026, but expects inflation to fall to 4.1% in 2027, revising upward its 2027 estimate from a July 3.9%. Higher energy costs are cited as a driver, alongside an AI investment boom. The IMF also ties the inflation outlook to the energy-supply path: it now expects the Strait of Hormuz to reopen in March 2027 and conditions to return to a pre-war state by October 2027.

The report adds a financial-conditions angle. It notes that global oil reserves are being drawn down by about 2.7 million barrels a day and are nearing levels that could trigger sharper price moves, while energy constraints could impair the AI-led momentum. It also warns that fiscal health is a growing headwind. Separately, the IMF says market calm may partly reflect “AI-related exuberance,” and that the “cushion” from policy buffers and adaptability is “rapidly narrowing.”

For traders, the key watch-outs are the implied path for energy prices as reserves approach sensitive levels, and how the uneven growth backdrop (countries with limited exposure to the supply shock but stronger AI-demand are said to be holding up) feeds into relative rate expectations and risk appetite across currency blocs.

Why this matters for FX

For FX, the IMF’s baseline affects central-bank rate paths and risk premia through (1) revised growth expectations, (2) inflation dynamics tied to energy costs and AI-driven investment, and (3) the assumed trajectory of Middle East energy disruption. It also highlights a more uneven, “skewed” global growth pattern, which can shift relative demand for safe havens and capital flows across higher- and lower-exposure currencies (including energy importers versus economies benefiting from AI/tech supply chains).
