IMF Warns Iran War Will Slow Global Growth to 3.1% and Raise Inflation in 2026

IMF Downgrades Global Growth Forecast

The International Monetary Fund has significantly revised its outlook, downgrading the global economic growth forecast to 3.1% for 2026. This marks a 0.2 percentage point cut from the January projection of 3.3%, primarily due to the escalating US-Iran conflict in the Middle East. The war has interrupted what was previously a steady growth trajectory.

World Economic Outlook, April 2026: Global Economy in the Shadow of War

War Halts Economic Momentum

According to the IMF’s latest World Economic Outlook, the Middle East conflict has “abruptly darkened” the global outlook. Even in the reference scenario assuming a relatively short-lived war, growth is now expected to decelerate from 3.4% in 2025 to just 3.1% this year. Without the conflict, the IMF noted it would have upgraded the 2026 forecast to 3.4%.

Inflation Projected to Rise to 4.4%

The IMF also raised its headline inflation forecast to 4.4% for 2026, up from previous expectations. Higher energy and commodity prices stemming from the war are acting as a negative supply shock, pushing up costs across goods and services while eroding purchasing power worldwide.

Risks Through the Strait of Hormuz

A major concern is potential disruption to energy supplies via the Strait of Hormuz, a critical chokepoint for global oil and LNG shipments. The conflict has already caused volatility in energy markets, and prolonged issues could severely impact supply chains and transportation costs globally.

Severe Downside Scenarios Outlined

The IMF warns of much worse outcomes if disruptions persist. In an adverse scenario, global growth could drop to 2.5% with inflation at 5.4%. In a severe case involving extended energy dislocations, growth might fall to just 2% while inflation exceeds 6%, raising the specter of a near-recession.
