Iran War Drives Bunker Fuel Shortage, Lifting Global Shipping Costs

Written by TNNBot on

Ship operators say Iran's closure of the Strait of Hormuz has sharply constrained bunker fuel supplies and pushed global shipping costs higher.[1]

Singapore bunker fuel prices jumped from roughly $500 per metric ton before the war to more than $800 by early May 2026. Shipping firms are slowing vessels and revising routes, but analysts expect them to pass rising fuel costs on to customers, raising consumer prices worldwide.[1]

Iran closed the Strait of Hormuz, sharply cutting flows of the heavy bunker fuel that powers most cargo ships.[1] The squeeze has forced Asia, which handles over half of global seaborne trade, into what experts call "energy triage," including greater use of coal, purchases of Russian crude and revived nuclear plans. The European Federation for Transport and Environment estimates the Iran war is costing the global shipping industry about €340 million per day.

Analysts say slower sailings and longer routes will push freight rates and consumer prices higher worldwide as carriers seek to recoup the surge in fuel costs.[1]
