The OECD warns that Middle East tensions are driving energy prices higher, eroding global growth prospects. Its March outlook projects world GDP at 2.9% in 2026, with G20 inflation reaching 4%. The United States economy will slow from 2% to 1.7% growth as consumer spending weakens. The euro area faces just 0.8% growth this year. The organization urges avoiding new export restrictions that could worsen supply shortages.
