Strait of Hormuz Still Effectively Shut: Few Ships Transit as Oil Slick Reaches UAE Beaches

The Strait of Hormuz, through which roughly one-fifth of the world’s oil and gas moved in peacetime, remains effectively closed to normal commercial traffic more than eight months into the Iran war. The IMF’s PortWatch tracker recorded just four transits on October 18, against a far higher pre-crisis baseline. Iran’s foreign minister said on Monday that the waterway’s management will not return to pre-war norms, and reference timelines note the creation of a Persian Gulf Strait Authority as Iran asserts sovereignty over the waterway.

Claims about control of the strait conflict sharply. Iran claims full control, while US officials say Iran has lost control and that crude flows have recovered. Both can be partly right, because Middle Eastern exporters have rerouted barrels through pipelines and alternative ports. Kpler data show regional oil exports averaged more than 24 million barrels a day in the week to October 18, above the pre-war level of 23.3 million, even though the strait itself carries a small fraction of its old traffic.

The human and environmental toll continues. On Monday the United Arab Emirates reported an oil slick from a tanker in the waters off Umm Al Quwain, and Al Jazeera said the oil had washed ashore and forced beach closures. Insurers and shipowners remain cautious after months of attacks on vessels, mines and a US naval blockade of Iranian ports.

Diplomacy has not yet changed the picture. Iranian state media denied sending a new proposal on reopening the strait through Pakistan, while Tehran’s stated position is that the waterway will not open until its seven conditions are met. Washington has so far prioritised nuclear concessions.

What to watch: weekly transit counts, any US escort operation, mine-clearing reports, and whether talks in Tehran produce a sequencing deal that swaps blockade relief for reopening. Figures from different trackers differ, so compare sources before drawing conclusions.
