A US official told Reuters on Thursday, 24 September, that about 60 commercial vessels transited the Strait of Hormuz on Wednesday, 23 September, carrying the highest daily volume of crude oil since early July. About 40 of those ships coordinated with the US military for protection. About 22 million barrels of oil exited the chokepoint, the official said, speaking on condition of anonymity. Reuters could not independently verify the figures. Newsquawk timed the defence-official line at 18:52 UTC on Thursday; Asharq Al-Awsat and Devdiscourse carried the same Reuters file later that evening and into Friday morning.
The print is a US volume claim, not a Kpler AIS day and not a CENTCOM blockade count. Operators who treat “60 ships” as a restored strait will misread both the traffic and the risk. The same Wednesday that the official described as the busiest crude day since early July is also the day UKMTO recorded the hit on the Antigua and Barbuda-flagged Capesize Cape Dao off Musandam, which killed an Indian seafarer and left the ship on fire and adrift. A high-volume day and a fatal projectile can sit on the same watch. One does not cancel the other.
Two censuses, one strait
Preliminary Kpler data cited by Reuters and Iran International on Thursday put AIS-visible Hormuz commodity transits at ten ships on Wednesday, up from seven on Tuesday and still below a 10-day average of about 17. Nine vessels entered and one exited. Those figures exclude ships that crossed with transponders off. Pre-war flow was on the order of 125 large commercial vessels a day — tankers, gas carriers, bulkers and boxes — about 20 percent of the world’s daily crude and LNG supply. The US official’s 60-ship set is therefore several times the visible commodity print and still less than half the pre-war daily count.
The gap is not a mystery if the two series are kept on separate ledgers. Kpler’s Reuters cut is a commodity-ship AIS snapshot. It does not count naval escorts, many smaller craft, or dark transits. NCAGS has been briefing facilitated traffic in the thirties over rolling 72- and 96-hour windows while AIS commodity days stayed in single digits. Admiral Brad Cooper said on 19 September that US-coordinated protection had moved more than one billion barrels of Gulf-partner crude through Hormuz over the previous couple of months and that volume in the prior two weeks was higher than at any point in the previous six months. Thursday’s 22-million-barrel exit is consistent with that US volume narrative. It is not proof that AIS-visible commercial traffic has recovered, and it is not a sailing window.
CENTCOM’s 23 September blockade increment — 115 commercial vessels redirected under the “steel wall” of Iranian ports and coasts — is a third number. Iran International noted the distinction on Thursday: one US campaign is trying to keep partner oil moving through the strait; the other is trying to keep trade out of Iranian berths. A ship in the 60-ship transit set can still be hailed, delayed or turned if the next port looks Iranian. A ship that coordinated with the US military for protection is not automatically outside Iran’s wartime controls, the Persian Gulf Strait Authority’s 77-vessel non-compliance list, or the projectile risk that hit Cape Dao the same day.
What the 22 million barrels do and do not mean
Twenty-two million barrels leaving Hormuz in a day is a large crude print against the single-digit AIS weeks that have defined September. It is not a return to the pre-war energy throughput that sat behind the 125-ship day. It also sits next to a New York diplomatic track that has not changed the water. Reuters reported earlier on Thursday that US and Iranian negotiators were exploring a phased path that would have Tehran reopen Hormuz and Washington lift the economic blockade of Iranian ports. Sources close to those talks have described a restored channel, not an agreed timeline. Iran’s Tuesday remark that the strait could reopen within seven days if Washington eased military pressure and lifted the blockade remains a mediator proposal, not a UKMTO, NAVAREA or IMO product. Ghalibaf’s line that Hormuz stays closed until US commitments are fulfilled has not been withdrawn.
An adviser to Iran’s supreme leader, Yahya Rahim Safavi, warned on Thursday that if the United States attacks again the front could expand from the Gulf and Hormuz to the Red Sea and “the Indian Ocean and perhaps beyond.” That is a geographic threat, not a sailing instruction. It does, however, sit in the same 24-hour window as the 60-ship claim. Operators who brief charterers that Wednesday “proved the strait is open” will have to explain both the unverified US volume and the same-day fatal hit, plus a senior Iranian warning that the theatre can widen.
Treasury Secretary Scott Bessent told Fox News that tankers “may get hit” and that “many of them just sail on.” That is a US official’s description of residual kinetic risk on a day Washington is also advertising a 22-million-barrel exit. It is not a reason to thin the watch, drop citadel drills, or treat a US coordination slot as a safe-conduct. Monday’s unnamed inbound tanker and the time-late outbound LPG debris product remain unnamed in official UKMTO warnings. The industry namings of LR Stephanie and Al Maryah are still not official products. Wednesday’s Cape Dao file is the named casualty. None of those ships is part of the 115 redirected-to-Iran count, and none of them is evidence that the 60-ship set crossed without being hailed or struck.
Operational implications
The practical problem for masters and operators is which census to put on the voyage order. Charterers will see “60 ships” and “highest crude day since early July” and ask why a ship should wait, dark-run, or deviate to Sohar STS. The answer is that the US official’s set is unverified, that Kpler still shows a teens-or-below commodity day, that about one-third of the claimed 60 ships did not, on the official’s own telling, coordinate with the US military, and that a coordinated transit is still a transit through a strait where projectiles are hitting engine rooms. War-risk underwriters will ask which series the fixture assumed. A clause written against a four-ship AIS day is not the same as a clause written against a 60-ship US print.
Bridge teams still need two scripts. If hailed by a US unit, record the unit, the time, the order and the destination stated, then notify owners, P&I and the war-risk desk before altering course. If hailed on the Iranian side, or if the ship is on the PGSA 77-list, the US coordination slot does not settle the call. Destination, last port and cargo nomination have to be consistent before the Gulf of Oman approach. A last-minute change toward Bandar Abbas, Kharg or Jask can move a hull from the “partner oil” set into the blockade set. A last-minute change away from an Iranian berth can still leave the ship inside Iran’s wartime traffic rules.
Crew welfare sits on the same SMS. India’s Forward Seamen’s Union asked for naval escorts after wiper Suraj Yadav, 26, was killed on Cape Dao. That request is not a corridor. It is a reminder that the seafarer risk has not tracked the US volume claim. Keep citadel, fire and medical plans current for engine-room and accommodation strikes. Keep UKMTO, NCAGS and NAVAREA IX live independently of any US escort slot. A 22-million-barrel day is a market input. It is not a reason to treat Hormuz as open.
What Operators Should Note
- Treat 60 ships and 22 million barrels as an unverified US official print, not as an AIS day. Reuters attributed the figures to an anonymous US official on Thursday and said it could not independently verify them. Do not brief charterers that Wednesday restored commercial traffic to 60 visible commodity hulls.
- Keep the Kpler commodity set on a separate ledger. Ten AIS-visible commodity ships on Wednesday, nine in and one out, versus seven on Tuesday and a 10-day average of about 17. Pre-war flow was about 125 large commercial vessels a day. Dark transits sit outside the Kpler cut. The US 60-ship set can include escorts, smaller craft and ships the AIS product does not count.
- Do not confuse a transit count with the 115 blockade redirections. CENTCOM’s 23 September increment is ships diverted from Iranian ports and coasts. The 60-ship claim is a Wednesday throughput number. A hull can appear in one series and not the other. Confirm next port, last port and cargo nomination before the Gulf of Oman approach.
- A US coordination slot is not a safe-conduct. About 40 of the 60 ships, on the official’s telling, coordinated with the US military. The other 20 did not. Cape Dao was hit the same Wednesday. Bessent’s “they may get hit” line is a residual-risk statement. Monitor UKMTO, NCAGS and NAVAREA IX independently of any hail.
- Do not convert the New York talks into a sailing window. A phased reopen-and-lift discussion, Iran’s seven-day mediator remark, and Safavi’s Indian Ocean warning are diplomatic and threat products. None of them is a UKMTO clearance, a NAVAREA, or an IMO restoration of UNCLOS transit.
- Write the fixture against both censuses. Name who pays if the owner refuses a Hormuz transit that charterers justified on the 60-ship print, and who pays if a coordinated ship is still hailed, delayed or struck. Keep the Sohar STS and Ras Tanura file live until an official, verified recovery sits in both the US and the AIS series.
- Keep crew and next-of-kin plans on the same clock as the volume claim. The Indian fatality on Wednesday is the live human file. A high-crude day does not reduce engine-room, fire or citadel readiness. Report while an approach or projectile is happening.
Regulas Shipping will keep lining the US official’s Wednesday volume claim against Kpler’s AIS commodity prints, CENTCOM’s blockade count and UKMTO warnings so operators can treat a 22-million-barrel day as a market input, not as a restored Strait of Hormuz.
