International Maritime Organization chief Arsenio Dominguez declared naval protection through the Strait of Hormuz cannot guarantee ship safety, calling military escorts a non-sustainable solution to the waterway's closure. The strait, vital for 20% of global oil trade, remains effectively shut following Iranian attacks on 18 vessels since hostilities began. Brent crude prices surged past $100/barrel, raising global economic concerns. Dominguez emphasized the strait's narrow, mountainous geography favors aggressors, leaving merchant ships vulnerable despite US promises of escorts that haven't materialized.

He urged shipowners to avoid sailing, warning crews face risks from limited port access and dwindling supplies. The IMO will convene to address operational dangers and call for conflict de-escalation.
