The United Nations has lowered its forecast for global economic growth in 2026, citing escalating energy market disruptions tied to the Middle East conflict and renewed inflationary pressure across major economies.
According to the U.N.’s midyear World Economic Situation and Prospects update, global GDP growth is now expected to reach 2.5% in 2026, down from the 2.7% forecast issued in January. U.N. economists warned that growth could weaken further to 2.1% under a more severe scenario tied to prolonged energy supply disruptions and higher commodity prices.
The downgrade reflects mounting economic fallout after U.S. and Israeli strikes on Iran and Tehran’s subsequent closure of the Strait of Hormuz, a critical transit route for roughly one-fifth of global oil and gas shipments. Analysts said the resulting surge in crude and fuel prices has intensified risks for inflation, trade flows and industrial production worldwide.
Energy shock reshapes global outlook
U.N. officials said higher energy and transport costs are reversing part of the global disinflation trend that had emerged earlier this year.
Global inflation is now projected to reach 3.9% in 2026, up from the January estimate and above 2025 levels. Developing economies are expected to absorb the largest impact, with inflation forecast to accelerate to 5.2% as fuel and import costs rise, according to the U.N. report.
Shantanu Mukherjee, director of economic analysis at the U.N. Department of Economic and Social Affairs, said rising refinery and transport costs are becoming a major drag on commercial activity and household purchasing power. The U.N. nonetheless said the global economy is not currently approaching recession conditions.
The International Monetary Fund has also warned that prolonged disruption in Gulf energy markets could significantly weaken global output. IMF economists previously projected that a severe energy scenario could push world growth closer to 2% while forcing central banks to maintain tighter monetary policy for longer.
Europe and West Asia face sharpest slowdown
The U.N. expects West Asia to experience the largest regional deterioration as infrastructure damage, weaker tourism activity and disrupted oil production weigh on economic performance.
Economic growth across the region is projected to slow sharply to 1.4% in 2026 from 3.6% last year, according to the report. Europe is also expected to face elevated pressure because of its reliance on imported energy supplies. The European Union’s growth rate is forecast to ease to 1.1%, while the United Kingdom is projected to expand by just 0.7% this year.
By comparison, the United States is expected to remain relatively resilient, with growth forecast at 2%. China’s diversified energy sourcing and strategic reserves are expected to cushion part of the energy shock, though its growth rate is still projected to slow to 4.6% from 5% in 2025. India is forecast to remain among the fastest-growing major economies with 6.4% growth this year.
Commodity markets and trade flows under pressure
The revised forecast comes as oil market volatility continues to spread through shipping, manufacturing and agricultural supply chains.
The International Energy Agency recently warned that global oil supply could fall below demand this year because of production outages and restricted tanker traffic through the Strait of Hormuz. OPEC has also reduced its 2026 global oil demand growth outlook as higher fuel prices weaken consumption and industrial activity.
Economists said sustained energy price increases could further slow trade activity, tighten financial conditions and raise borrowing costs for heavily indebted developing economies.
The U.N. warned that weaker investment flows, elevated geopolitical uncertainty and persistent inflation risks may continue to weigh on the global economy through 2027 unless energy markets stabilize and supply routes normalize.
