Iran has imposed strict controls over the Strait of Hormuz, allowing only two tankers to pass daily, leaving hundreds of ships stranded. Previously, about 100 tankers traversed the strait each day. According to Kpler, 400 tankers remain stuck as Iran selectively permits passage, primarily for Iranian vessels, after verification. J.P. Morgan analysts suggest this selective passage is politically motivated, with Iran allowing only non-U.S. and allied ships to pass. Despite the strategic importance of the Strait of Hormuz, which handles one-fifth of global crude oil transport, alternative routes remain limited. Efforts by the U.S. to secure naval escorts have not materialized, and allies have shown little interest in intervening. Since the conflict began, 21 maritime incidents have been reported in the region, including 16 attacks, according to UK Maritime Trade Operations.
