The International Monetary Fund (IMF) downgraded its global growth forecast for 2026 to 3%, citing the economic impacts of the ongoing Iran war. This marks a decrease from the previous estimate of 3.5% for 2025, according to a report released on Wednesday. The IMF attributed the slowdown to an energy shock caused by the conflict, which has disrupted oil supplies and contributed to rising prices.
Key Details
The war has particularly affected the Strait of Hormuz, a critical passage for a significant portion of the world's crude oil and natural gas. Following attacks by the U.S. and Israel, Iran responded by shutting down the strait, leading to a nearly 32% increase in oil prices this year, the IMF reported. Global consumer prices are also expected to rise by 4.7% in 2026, up from 4.1% in 2025.
Despite the challenges posed by the Iran war, the IMF noted that the global economy has shown resilience, partly due to increased investment in artificial intelligence and other technologies. Petya Koeva Brooks, deputy director of the IMF’s research department, stated,
The world economy has weathered the shock from the war better than feared.
Countries with their own energy production and those benefiting from AI investments are better insulated from the war's economic fallout.
Background
The IMF projects a rebound in global growth to 3.4% in 2027, as the impact of the Iran conflict begins to stabilize. Investors will be particularly focused on how energy markets react to ongoing geopolitical tensions and any potential resolutions to the conflict.

The downgrade in growth forecasts is likely to affect energy markets, particularly oil prices, as investors reassess supply dynamics amid geopolitical tensions. Rising energy costs could further squeeze consumer spending and corporate margins in sectors reliant on stable energy prices.
Watch for the IMF's next economic outlook report, scheduled for release in April 2027, which may provide further insights into the long-term impacts of the Iran war on global growth.
