- IMF lowers 2026 global growth forecast as war shock lifts inflation risks
The International Monetary Fund has cut its forecast for global growth in 2026, warning that the war in the Middle East is creating a fresh and dangerous drag on an already fragile world economy.
In the executive summary of its April 2026 World Economic Outlook, the Fund said global growth is now projected at 3.1 per cent in 2026 and 3.2 per cent in 2027, down from the recent pace of about 3.4 per cent in 2024 and 2025. The 2026 forecast is 0.2 percentage point lower than in the IMF’s January update, while global headline inflation is now expected to rise to 4.4 per cent in 2026 before easing to 3.7 per cent in 2027.
The Fund’s message is that the war has become the dominant new shock. It said the conflict, which broke out at the end of February, is acting as a powerful counterforce to the tailwinds that had previously been supporting the global economy, including technology-related investment, easier financial conditions, a weaker US dollar, and policy support. Instead, the war is now feeding directly into commodity markets, inflation expectations and financial conditions.
The IMF has avoided calling this a conventional baseline forecast. Because of the fluid nature of the conflict, it said the report instead presents a “reference forecast” built on the assumption that the war will remain limited in duration and intensity, with disruptions fading by mid-2026. Even under that relatively restrained assumption, the global economy still weakens.
That point matters because it shows how much worse the outlook could become if the conflict deepens. The IMF said that in an adverse scenario with larger and more persistent increases in energy prices, global growth would slow further to 2.5 per cent in 2026, while inflation would rise to 5.4 per cent. In a more severe scenario involving greater damage to energy infrastructure, global growth would fall to only about 2 per cent in 2026, while headline inflation would move to just above 6 per cent by 2027.
The burden of the shock, however, will not be evenly shared. The IMF said the apparent modesty of the global revisions masks a far sharper hit to the conflict region itself and to more vulnerable economies elsewhere, especially commodity-importing emerging markets and developing economies with existing fragilities. For that group, the downward revision to growth in 2026 is 0.3 percentage point, while the outlook for advanced economies is broadly unchanged.
There is an important counterfactual in the report. The IMF said that without the war, it would actually have revised global growth upward for 2026 by 0.1 percentage point to 3.4 per cent. In other words, the downgrade does not reflect a world economy that was already rolling over on its own. It reflects an economy that was improving, but has now been knocked back by geopolitical disruption.
The wider risk picture is also darkening. On page 2 of the summary, the IMF warns that downside risks still dominate even after the materialisation of a major geopolitical shock. It lists the possibility of an even larger energy crisis, renewed trade disputes, fiscal strains, weaker institutional credibility, and a correction in financial markets if confidence around artificial intelligence-driven profitability fades.
Against that backdrop, the Fund’s policy advice is notably cautious. It says central banks must remain vigilant and be ready to act decisively if inflation expectations become destabilised. Governments, meanwhile, should preserve fiscal sustainability, protect the most vulnerable with targeted, temporary and timely support, and rebuild buffers by mobilising revenues, reprioritising spending and managing any windfall gains prudently.
The IMF also argues that countries should avoid leaning on trade restrictions as a tool for correcting imbalances, warning that such measures can worsen output. Instead, it calls for stronger cooperation, more predictable trade policy and coordinated efforts to restore stability in international economic relations. That is a notable signal at a time when trade fragmentation and geopolitical realignment are increasingly shaping the world economy alongside inflation and energy markets.
For Africa and other import-dependent developing economies, that warning will resonate particularly strongly. The Fund’s latest outlook suggests that the costs of the Middle East war will be felt not only through fuel and fertiliser, but through tighter policy trade-offs, weaker buffers and a more uncertain growth path in the months ahead.
