Key takeaway

General License X authorises a trade the mined, uninsured strait cannot yet carry.

Hormuz transits collapsed from 55 ships on 20 June to 12 on 22 June, a 78 per cent drop between those two days, with five of eight inbound vessels running with their automatic identification systems switched off⁠1. AIS transponders broadcast a ship's identity and position; switching them off hides the vessel. The maritime intelligence firm Windward called the pattern a "late-blockade baseline," closer to wartime dark-fleet running than a functioning open strait⁠2. The collapse fell on the very day General License X authorised the oil to move.

The larger 20 June traffic had run through Oman's territorial waters, the bypass route that has carried Gulf crude since the closure, and markets have consistently priced that Oman route over Iran's words. Brent Crude fell to about $78 a barrel on 22 June, its lowest since early March, pricing the 60-day relief rather than delivery: a permit to sell oil that only 12 ships actually moved.

The freight and spread economics of a dark, fee-charged corridor are the European oil desk's beat. A 78 per cent fall on the exact day the licence issued is the cleanest evidence that the bottleneck is mines and war-risk, not sanctions, so lifting the sanctions moved nothing on the water. GL X authorised a trade the strait cannot physically carry yet.

Deep Analysis

In plain English

Before the conflict, around 55 ships crossed the strait of Hormuz every day, carrying roughly a fifth of the world's oil. On 22 June, the same day the US gave Iran special permission to sell oil again, only 12 ships crossed, and five of them had turned off their GPS trackers, a sign that their crews were trying to avoid being noticed in a war zone. The oil market noticed the mismatch. Brent Crude, the global oil price benchmark, settled around $78 a barrel, lower than before the conflict, but still elevated. Traders were pricing in the hope that the 60-day permission slip would eventually help reopen the strait fully, rather than treating it as done. A permission to sell oil is not the same as a safe route to ship it.

Different Perspectives
United States (Joint Maritime Information Center)
United States (Joint Maritime Information Center)
The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.
United Kingdom (CPS and Counter Terrorism Policing)
United Kingdom (CPS and Counter Terrorism Policing)
The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.
Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.
Qatar (mediators)
Qatar (mediators)
Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.
Korea Shipowners' Association
Korea Shipowners' Association
The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.
Kuwait (foreign ministry)
Kuwait (foreign ministry)
Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
