The International Monetary Fund on Tuesday cut its 2026 global growth forecast to 3.1%, down from the 3.3% projected in January, citing devastating economic spillover from the U.S.-Iran conflict and the partial closure of the Strait of Hormuz. The revision, released during the IMF-World Bank Spring Meetings in Washington, represents the fund's starkest warning yet about the conflict's lasting economic damage.
IMF Chief Economist Pierre-Olivier Gourinchas told reporters that the world economy was "thrown off track" by an event that was not in any institution's baseline scenario at the start of the year. The fund raised its global inflation forecast to 4.4%, a 0.6-point upward revision from January, driven by the 28% surge in oil prices since the conflict began in late February.
Regional Forecasts Diverge Sharply
The U.S. economy escaped with a modest downgrade to 2.3% from 2.4%, reflecting resilient domestic consumption offset by surging energy prices. The Eurozone bore the brunt with growth now forecast at 1.1%, down sharply from 1.4% in January. Germany faces the most severe impact with its economy forecast to contract by 0.2% in 2026.
The Middle East and Central Asia region suffered the steepest cut, with the IMF slashing its 2026 forecast by 2 full percentage points to 1.9%, reflecting direct economic destruction from military operations and infrastructure damage. Sub-Saharan Africa, insulated from direct energy route disruptions, remains relatively stable at 4.3%.
Hormuz Blockade Is the Central Risk
The fund's downside scenario — described as having "meaningful probability" — envisions the Strait remaining closed through the summer. In that case, global growth could fall to 2.4%, oil prices could top $130 per barrel, and global inflation could breach 6%. The IMF called on G20 nations to coordinate emergency fiscal responses.
Gourinchas urged negotiators to prioritize a ceasefire, warning that "the longer this conflict persists, the deeper and more durable the damage to the global trading system will be." Financial markets responded with a modest relief rally after the IMF said it does not expect the crisis to trigger a full-blown global recession under its central scenario.
