Strait of Hormuz Blockage Triggers Historic Global Oil Supply Crash

The blockage of the Strait of Hormuz has caused the largest supply disruption in the history of the global oil market, with the International Energy Agency reporting losses of 12.8 million barrels per day. The conflict, which began in late February 2026, is approaching its 100th day and has triggered rising oil and gas prices, damaged global supply chains, and reignited inflationary pressures across Europe and the United States.

International institutions have responded by lowering global growth forecasts for 2026. The OECD expects growth to slow to 2.8 percent, while the International Monetary Fund projects global inflation to reach 4.4 percent. The World Bank projects that global energy prices will rise by 24 percent this year.

Economic leaders warn that the instability is creating a disproportionate burden on vulnerable populations. World Bank Chief Economist Indermit Gill stated that the poorest people will be hit hardest, as will developing economies struggling with heavy debt. OECD Secretary-General Mathias Cormann noted that economic and social costs increase the longer the disruptions last. These financial strains persist as negotiations between the United States and Iran continue to see-saw, leaving the future of regional shipping uncertain.
