IMF Lifts 2026 Global Growth to 3.1% on AI Spending, Warns of Bond Risks

The upgrade is narrow rather than broad-based. The fund left 2027 global growth at 3.4%, down from 3.5% in 2025, and cut China's forecasts for both years by 0.1 percentage point, to 4.5% in 2026 and 4.0% in 2027. The United States is projected at 2.3% in 2026, unchanged from July and 2025, with 2027 revised up to 2.3% from 2.2%. The Euro Area is seen growing 1.1% in 2026, up from 0.9% in July, on resilience in Germany, Italy and Spain. The IMF also noted that 32 countries now account for 95% of global growth, down from about 54 countries in April — a sign of how concentrated the expansion has become.

Energy is the pivot of the forecast. The IMF now projects average oil at $96 a barrel in 2026 and $87 in 2027, versus $89 and $78 in July. That revision rests on an explicit set of assumptions: the Strait of Hormuz reopens and shipping resumes in March 2027, with a return to broad pre-war conditions by October 2027. If the Middle East war worsens instead and oil averages $130 a barrel through the first quarter of 2027, the fund estimates global growth would be 0.2 percentage point lower in 2026 and 0.5 percentage point lower in 2027. Higher oil works through the economy as a tax on households and fuel-dependent businesses, which is why the IMF credits AI investment with absorbing part of that hit in key economies.

The fund's bigger concern is what happens if the AI spending that is carrying the forecast reverses. In a scenario where AI investment unwinds and asset prices fall sharply, global GDP output would be 1.1% lower by 2028 — a contraction scenario the IMF attaches to a technology cycle whose capital spending is heavily concentrated in a handful of firms and countries. The same forecast warns that bond market risks have risen since the April stability report, a period in which rising long-term yields have raised the cost of financing government debt and corporate investment. Both threads point the same way: this expansion depends on continued AI capital spending and on borrowing costs staying manageable.

Global headline inflation is projected to rise to 4.7% in 2026 before easing to 4.1% in 2027, matching the 2025 level — an outcome that keeps pressure on central banks. For Japan, the IMF expects 0.7% growth in 2026 and 2027 and assumes the Bank of Japan raises interest rates gradually toward a neutral setting. Taken together, the projections describe a world where growth holds up on investment and resilient services, inflation cools only slowly, and the two main risks — an AI capex reversal and a worsening Middle East conflict — sit on either side of the baseline. The concrete condition that would validate the upgrade is continued AI investment and the assumed reopening of Hormuz; a sustained oil price near $130 or a sharp pullback in technology spending would move outcomes toward the lower scenarios.
