Iran War Triggers Worst Global Trade Disruption in 80 Years as Hormuz Blockade Enters Fourth Week

The Iran war has triggered what Al Jazeera described as the worst trade rupture in 80 years, with approximately 2,000 vessels and 20,000 seafarers stranded near the Strait of Hormuz. Non-Iranian oil flows through the chokepoint have collapsed from 14 million bpd to roughly 400,000 bpd. CSIS analysis notes Iran is "fighting a different war, one aimed at the global economy," with its navy severely degraded (50+ ships sunk) but its economic warfare strategy proving effective. Qatar declared force majeure at the Ras Laffan LNG complex after a March 2 drone strike, cutting a major global LNG supply.

Analysis
The 14M-to-400K bpd collapse in non-Iranian Hormuz traffic represents a 97% reduction in third-party shipping through the world's most critical energy chokepoint. The CSIS framing, Iran is winning the economic war while losing the military one, captures the fundamental asymmetry of the conflict. Qatar's Ras Laffan LNG force majeure alone affects approximately 30% of global LNG trade.
