The head of the International Monetary Fund warned that the ongoing Iran war will lead to a downgrade in the global economic growth forecast, even if a fragile ceasefire holds. IMF Managing Director Kristalina Georgieva said the conflict has driven up energy prices, damaged infrastructure, and eroded business and consumer confidence worldwide.

Why it matters

The Iran war has had a significant impact on the global economy, with rising energy costs, supply chain disruptions, and dampened business sentiment. This will slow economic growth worldwide, posing challenges for policymakers who have limited ability to support their economies due to high existing debt levels.

The details

The IMF had been poised to upgrade its global growth forecast to 3.3% in January, but the outbreak of the Iran war on February 28th changed the outlook. The conflict has driven up oil and natural gas prices, damaged energy infrastructure, disrupted fertilizer shipments, and eroded confidence among businesses and consumers.

  • The Iran war began on February 28, 2026.
  • The IMF was set to upgrade its global growth forecast to 3.3% in January 2026 before the war started.
  • On April 9, 2026, the IMF Managing Director warned that the global growth forecast will now be downgraded due to the war.

What they’re saying

“'Had it not been for this shock, we would have been upgrading global growth. But now, even our most hopeful scenario involves a growth downgrade.'”

— Kristalina Georgieva, IMF Managing Director

What’s next

The IMF will release its updated global growth forecast next week, which is expected to show a downgrade from its previous projections due to the impact of the Iran war.

The takeaway

The Iran war has dealt a significant blow to the global economy, with rising energy costs, supply chain disruptions, and eroded business confidence all contributing to a slowdown in economic growth worldwide. Policymakers will face challenges in supporting their economies given high existing debt levels.
