What organization revised down its global growth outlook in March 2026 due to the war in the Middle East?

The global economic landscape often faces unforeseen challenges, and in March 2026, a prominent international organization adjusted its forecast for worldwide growth in response to escalating tensions in the Middle (Review) East. This influential body, the Organisation for Economic Co-operation and Development, or OECD, highlighted the significant impact of the conflict on the global economy. Their analysis pointed to an energy supply shock as a primary concern, leading to higher energy prices and increased inflationary pressures across various economies.

The OECD, an intergovernmental organization established in 1961, plays a crucial role in promoting economic growth, sustainable development, and improved living standards among its 38 member countries. It achieves this by gathering extensive economic and social data, conducting in-depth analysis, and providing evidence-based policy recommendations to governments. The organization regularly publishes its Economic Outlook, offering critical insights and forecasts on global economic trends, making it a key reference for policymakers and businesses alike.

In its March 2026 interim report, the OECD specifically noted that the evolving conflict was testing the resilience of the global economy. The disruption of energy infrastructure and shipments, particularly through vital routes like the Strait of Hormuz, caused a surge in prices for crude oil, gas, and other energy products. This, in turn, was projected to markedly increase business costs and dampen consumer demand, ultimately offsetting earlier growth momentum and leading to a slower global growth trajectory than previously anticipated.
