after 110 days of closure during us-iran conflict, major shipowners moved tankers through the strait of hormuz for the first time, with grimaldi, cosco, knutsen and nyk vessels crossing under a us-iran interim agreement. as of june 22, 441 large vessels remained clustered near sohar and fujairah awaiting full reopening. a 110-day complete closure of the world's most important oil chokepoint is without modern precedent; the slow queue drawdown indicates operators remain cautious despite ceasefire signals.
