Hormuz Closure Triggers Worst Maritime Supply Chain Disruption in Modern History with 95% Transit Collapse
UN News reported as of late April that US-Israeli strikes on Iran, beginning in late February, had left up to 20,000 seafarers stranded on some 2,000 vessels in the Persian Gulf, unable to transit the Strait. UNCTAD reported in March that the Strait carries roughly a quarter of global seaborne oil trade plus significant LNG and fertilizer volumes, and that Brent crude had risen above $90 per barrel.

Analysis
The IMO Secretary-General's framing of detained vessels as deliberate geopolitical leverage, per UN institutional reporting with limited corroboration, distinguishes this closure from disruptions resolved through escort arrangements. Brent above $90 alongside LNG and fertilizer corridor stress indicates markets have priced in extended closure, removing incentive for either party to offer rapid partial reopening. Commercial shipping through Hormuz isvery unlikely to return to pre-crisis volumes by mid-July 2026. Tehran could calculate sustained closure accelerates its own economic deterioration faster than continued military pressure and offer partial transit as a pre-ceasefire bargaining chip. Oil-dependent importers face a mid-July decision on alternative routing contracts that cannot be deferred without locking in avoidable costs either way.
