IMF Slashes 2026 Growth Forecast on Mideast Tensions

The International Monetary Fund (IMF) on Tuesday lowered its forecast for global economic growth in 2026, pointing to energy-price shocks and supply disruptions linked to the ongoing Iran war. The Washington-based institution set its updated projection for 2026 global GDP growth at 3.1%, trimming 0.2 percentage point from its January view.

The IMF warned that the economic damage could intensify if the conflict becomes deeper and lasts longer. It said the global economy could be pushed close to recession conditions, especially in a situation where oil prices stay above $100 per barrel through 2027.

To frame the range of possible outcomes, the IMF laid out three scenarios tied to the duration of the war and the path of oil prices. In its most optimistic “reference scenario,” the IMF assumed the Iran war is short-lived and that oil prices average $82 per barrel in 2026; under that set of assumptions, global GDP growth is still projected at 3.1%.

The IMF’s “adverse scenario” assumes a longer conflict and oil prices around $100 per barrel in 2026. Under that scenario, the IMF said global GDP growth would slow to 2.5%.

In the most severe case described by the IMF, the conflict extends and deepens, with oil prices averaging $110 per barrel in 2026 and $125 in 2027. Under that scenario, the IMF projected global growth would fall to 2.0%, a pace it said has historically been associated with global recessions.

IMF Chief Economist Pierre-Olivier Gourinchas said persistently high oil prices would add pressure to inflation expectations. He indicated that this could lead central banks to tighten policy further, depending on how inflation expectations evolve.

The IMF also drew a distinction between a brief energy shock and a more damaging, sustained one. It said central banks could look through a short-lived rise in energy prices if inflation expectations remain anchored, but in the severe scenario it described, global inflation in 2026 would exceed 6%, compared with 4.4% in the reference scenario.

Alongside the global outlook, the IMF adjusted regional projections for 2026. It set U.S. growth at 2.3% and Eurozone growth at 1.1%, reflecting what it described as differing effects from the conflict and other economic factors.
