OECD forecasts 2.8% global growth for 2026

The OECD said on June 3 that it expects global growth to slow to 2.8% in 2026, as conflict in the Middle East disrupts energy and commodity markets and raises the risk of weaker output and higher inflation. The Paris-based organization published the forecast in its latest Economic Outlook, released during its ministerial meetings. The report said its baseline assumes the current energy shock eases by mid-2026. The OECD said a longer disruption to oil and gas production and shipping would produce a materially weaker outcome. ### Why did the OECD cut the story of 2026 growth to energy and war? The OECD said the conflict in the Middle East has caused a “major disruption” to global energy and commodity markets, pushing up prices and increasing financial-market volatility. In its March interim report, it had already warned that a prolonged disruption to exports from the region could aggravate shortages of key commodities, weaken private demand and raise financial-stability risks. (oecd.org) Stefano Scarpetta, the OECD’s chief economist, said the June baseline assumes the current energy-price shock is time-limited and that disruptions around the Strait of Hormuz are resolved relatively quickly, according to CNBC’s account of the report briefing. Reuters reported the OECD said the global outlook now depends heavily on how long the war lasts. (oecd.org) ### What exactly is the OECD forecasting? The OECD said global growth is projected to slow from 3.4% in 2025 to 2.8% in 2026, before recovering to 3.1% in 2027 under its baseline scenario. Reuters and other reports said that path is broadly in line with the organization’s March projections, but only if the energy shock begins to ease this year. (cnbc.com) The June 3 release follows an OECD media advisory issued in May saying the organization would publish a full Economic Outlook covering the world economy, OECD members, G20 countries and key partners on Wednesday, June 3, 2026. ### How much worse could the outlook get if disruption persists? (cnbc.com) The OECD said a more prolonged disruption to energy production and shipping would cut growth much further. Morningstar, citing the report, said the organization’s severe scenario would see global growth slow to 2.1% in 2026 and 1.8% in 2027 if the energy disruption stretches well into next year. Reuters similarly reported recession in some countries and sharply higher inflation would become a real possibility if the conflict drags on. (oecd.org) The March OECD report said any broader price shock from Middle East exports would likely require governments to target support narrowly and preserve incentives to reduce energy use, while central banks might need to adjust policy if price pressures broaden or growth weakens. ### What is the practical takeaway from the report? (morningstar.com) The OECD’s June forecast ties the 2026 global outlook to the duration of the Middle East energy shock rather than to a broad-based collapse already underway. In the baseline, growth slows but remains positive. In the prolonged-disruption scenario, the organization says weaker output and higher inflation would spread more widely across economies. (oecd.org) The OECD said on its website that the June 3 publication is its latest full Economic Outlook. The organization’s next regular update is its interim outlook cycle, which its recent publication calendar shows is scheduled for September 2026. (oecd.org) (cnbc.com)
