Iran says it has opened dedicated Hormuz lanes for Iraqi oil

Iranian Foreign Minister Araghchi told Iraq's state news agency INA on 20 October that dedicated lanes had been opened in Hormuz for ships carrying Iraqi oil. The strait remains closed to general commercial traffic; IMF PortWatch counted only 4 transits on 18 October.

Location: HORMUZ

According to Rudaw, Araghchi said the dedicated lanes were opened to reduce Iraq's economic losses. Iran and Oman have agreed routes in and out of the strait, with maps and coordinates already drawn up. To become official, they must first be registered with the IMO, the UN's maritime agency. Araghchi said these technical arrangements did not mean the strait would reopen to general traffic without a political deal between Tehran and Washington. Tehran's 7-day plan envisages fully reopening the strait on day 6. Araghchi said the US had accepted the terms but then added new, undisclosed conditions.

The value of selective passage shows up in freight data. According to an IEA assessment cited by gCaptain, Gulf–Asia crude shipping costs topped 37 dollars a barrel in mid-October, five times pre-war levels. Freight for a 2-million-barrel supertanker exceeded 74 million dollars, against less than 15 million before the war. Kpler data show the share of Gulf crude bypassing Hormuz rising from about 17% before the war to 40% in September. Traders reselling Iraqi crude can earn 20 dollars a barrel more than before the war.

The messages conflict. According to a Newsquawk round-up, the Revolutionary Guards declared on 21 October that the strait was completely closed and no passage would be allowed. Flow data diverge as well. Bloomberg reported that Kpler measured Gulf crude and condensate flows at 24.6 million barrels a day in the week to 18 October, while Vortexa put them at 18 million. The same round-up said Iraq closed the Sheeb crossing on the Iranian border on 21 October.

Talay assessment

Bottom line

By keeping the strait closed to general traffic while granting Iraq selective passage, Iran is building a filter in which Tehran decides who gets through. The plan to take the coordinates agreed with Oman to the IMO is an attempt to anchor that control in an international document. The most likely path is that selective passage continues and a general reopening stays tied to a political deal with the US.

Likely effects

Iraqi exportsPositiveWeeks
According to Kpler, traders reselling Iraqi crude earn 20 dollars a barrel more than before the war; the dedicated lanes protect that flow.
FreightNegative1–6 months
The IEA says Gulf–Asia shipping costs have topped 37 dollars a barrel; because selective passage does not free up tonnage, costs stay high.
Legal regime of the straitNegative6 months+
If the coordinates drawn up with Oman are registered with the IMO, Iranian approval for passage could harden into a permanent regime.
