The IMF Slashed Global Growth to 3% — and Its Big Assumption Is Already Falling Apart

Editor's note: The IMF's July WEO update was released July 8, before Trump's July 13 Hormuz toll announcement and the latest US-Iran hostilities. The fund's baseline assumes Hormuz reopens this month — an assumption now in serious doubt.

The IMF just cut its 2026 global growth forecast to 3.0% — the slowest in two years. Oil is up nearly 32% this year. Inflation is climbing. And the entire forecast rests on an assumption that's already falling apart: that the Strait of Hormuz reopens this month (IMF WEO, Jul 8; NYT, Jul 8).

The update, titled "Global Economy in Cross Currents of War and Technology," projects 3.4% growth for 2027. The 2026 figure is down from 3.5% in 2024–25 and 0.1 points below the IMF's April forecast (IMF WEO PDF, Jul 8). Global headline inflation is expected to rise to 4.7% in 2026, up from 4.1% in 2025 (Cyprus Mail, Jul 10).

Two forces, one winner

The IMF framed this as a contest between a negative supply shock from the Middle East conflict and a positive technology cycle driven by AI investment. The divergence is stark. The top four net exporters of AI-related hardware — Taiwan, South Korea, Thailand, and Malaysia — experienced an average positive growth surprise of 4.4 percentage points. The rest of the world averaged minus 0.3 (IMF WEO PDF, Jul 8).

The US is projected to grow 2.3% in 2026 — unchanged from April. The eurozone was downgraded to 0.9%, from 1.1%. Germany was cut to 0.7% from 0.8% (Washington Times, Jul 8). If you're in Europe, this is your recession warning shot. If you're holding AI stocks, congratulations — you're the growth story.

The Hormuz problem

Here's the catch that makes this forecast worth less than the paper it's printed on. The IMF's July baseline assumes the Strait of Hormuz reopens later this month (LA Times, Jul 8). That was already questionable on July 8. Five days later, Trump announced a 20% toll on all Hormuz cargo and reinstated a naval blockade. US-Iran hostilities renewed. The strait is not reopening this month.

The NYT reported that the US rescinded a sanctions waiver on Iranian oil exports on July 7 — one day before the IMF released its update (NYT, Jul 8). At a press briefing, the IMF said risks "remain tilted to the downside." The fund also warned of "trade fragmentation" and "potential corrections in market expectations for AI."

In other words: the 3.0% number is almost certainly too optimistic. If Hormuz stays disrupted — and every indication says it will — oil goes higher, inflation goes higher, and growth goes lower. The IMF knows this. They said so. They just can't model a war that's still being fought. So they assumed it ends. It hasn't.
