Iran's Hormuz blacklist turns out to be a target list, and its own regulator said so

The strait authority's eight earlier announcements threatened fees, fines, detention and the loss of insurance; this morning's says the tankers already on its list are the ones that got hit.

The body that hit the tankers is now the body that keeps the paperwork. At 02:44 UTC this morning Tasnim carried Iran's Persian Gulf Strait Affairs Authority explaining three Emirati oil tankers struck in the strait in recent days: they were already on its non-compliance list. Mehr ran the same account three hours later - hit after breaching Hormuz rules. The Revolutionary Guard is nowhere in either item, and in this record that has never happened before. Every previous Iranian account of a merchant hull struck in the strait, from the IRGC Navy commander citing two ships that 'ran into trouble' in March to the Togo-flagged tanker on 18 September, came from the Guard or its navy. A regulator has claimed the shooting, and given a filing status as the reason.

What makes that a turn rather than a louder threat is the ladder it sits on top of. Eight PGSA announcements precede this one in this record, and every instrument in them is commercial or administrative: permits and passage fees at the authority's launch on 18 May, mandatory Tehran-approved insurance on 19 June, suspension of transit permits on 12 July, fines, detention, confiscation and the loss of future passage on 23 August, the listing of vessels that assist violators the next day, an update to the blacklist itself on 3 September, a warning to insurers, protection and indemnity clubs and classification societies against serving listed ships on 14 September, and the listing of charterers who force ships off approved routes on 27 September. Not one of the eight mentions force. The ninth does, in the past tense.

Look at who got named, because that is its own finding. Across the 300 items in this record of Tehran's English wire, the words Emirati, UAE and ADNOC do not appear - not once - before 02:44 this morning. The Emirates own the most-struck fleet of the crisis: eight UAE- or ADNOC-owned and -operated hulls among the 73 attacks this site attributes to Iran through 14 August, every one of those attributions made by the UAE or by UKMTO rather than by Tehran, and the UAE's word for them was piracy. The first time Iran mentions the Emirates at all, it is to classify their ships.

The difference from 18 September is the tense. That morning the IRGC Navy named the Trend and said it had been hit for attempting an illegal passage - a reason attached to one ship after the fact. A list is not that. It exists before the transit, it is maintained, it was updated on 3 September, and on this morning's account it already held the hulls that burned. Which also re-reads the 14 September warning: insurers and classification societies were told that covering a listed vessel would cost them their standing with Tehran, and they have now been told it marks the hull.

So the thing to watch is no longer the next strike but the list - and the list is the one document in this regime nobody outside Tehran has seen. Nine announcements report that it exists, is updated, and now binds charterers and insurers; not one names a vessel on it. An owner cannot look up its own status, which means the only party that knows which hulls are targets is the party doing the shooting, and it has just said the two sets are the same. Expect no confirmation from the tape: days carrying Iranian state-media statements move Brent 0.88 times as much as quiet days in this record, at a permutation p of 0.72, which is a null, and the last official close is $113.96 on 29 September, three sessions before any of this. The traffic being sorted is in any case down to 93 transits in the 25 days from the blacklist update to 27 September - 3.7 ships a day, against 58.5 a day in January.

† PGSA announcements are items in iran_statements.json where the authority is the acting body (18 May, 19 June, 12 July, 23 and 24 August, 3, 14 and 27 September); the 12 July item is carried jointly with an IRGC Navy closure declaration and its PGSA sentence concerns permits. Attacks and the UAE/ADNOC hull count are from incidents.json, 28 February to 14 August; transits from timeline.json, to 27 September. State-media figures are the words_deeds.json institutions table: n=21 days, 0.88x quiet days, p 0.716 - a null. Brent is the official EIA closes, ending 29 September.
