Iran fired ballistic missiles at a US aircraft carrier and a destroyer on 5 September. Within hours CENTCOM disabled two Iranian crude carriers and destroyed a third, at a ratio Admiral Brad Cooper stated out loud. Both governments then described the same day differently, and nobody outside them can check either account.
Both governments acted on 5 September; only the American side left documents an outsider can check.
The IRGC fired ballistic missiles at a US aircraft carrier and a guided-missile destroyer on 5 September. CENTCOM says both ships evaded the attack unharmed; the IRGC says both were hit and withdrew.
United StatesIran's Revolutionary Guard fired ballistic missiles at a US aircraft carrier and destroyer in the Arabian Sea on 5 September. The US says both ships dodged the attack unharmed; Iran says the missiles struck and both withdrew.
Neither side has shown proof. Hours later the US hit back for real, destroying three Iranian oil tankers, so an unverified claim underlies a very real reprisal.
Hours after the missile attack, CENTCOM said American forces had permanently disabled M/T Downy off Kharg Island and M/T Stark 1 near Jask, and destroyed M/T Kylo in the Gulf of Oman.
CENTCOM says American forces disabled the Iranian tankers M/T Downy and M/T Stark 1, and destroyed the empty M/T Kylo, hours after the missile attack on two US warships.
Admiral Brad Cooper put a number on the reprisal: three tankers destroyed for every two US ships Iran targets, a rate now public and checkable.
Treasury designated Golden Global Yatirim Bankasi and two affiliates on 4 September, alleging they moved tens of millions of dollars for the IRGC-Qods Force and supplied correspondent banking access.
The US Treasury blacklisted a Turkish bank, Golden Global Yatirim Bankasi, and two affiliates on 4 September, accusing them of moving IRGC money and giving Iran a route into dollar banking.
Treasury gave counterparties until 19 September to wind down existing business before sanctions bite fully, a grace period called General Licence CC.
The IRGC Navy said it had attacked three oil tankers on an unauthorised Hormuz route and three vessels it called American-affiliated. The same statement acknowledged damage to Iranian tankers.
United StatesIran's Revolutionary Guard said its navy hit six vessels on 5 September: three tankers on a route it called unauthorised, and three it called American-linked. It named no ship and gave no location.
The same statement admitted damage to Iranian tankers, an unusual concession. None of the six claimed strikes has been independently confirmed.
At 19:04 on 4 September the bank filed notice with Turkey's Public Disclosure Platform saying the parties named by OFAC are not its customers. CNBC-e reported it intends to contest the listing.
Hours after the US named it, Golden Global Yatirim Bankasi filed a denial with Turkey's disclosure platform, KAP, saying the people OFAC named are not its customers.
Turkish broadcaster CNBC-e reported the bank intends to contest the listing, though no legal challenge has actually been filed yet.
The Associated Press reported that operators keep moving oil on a southern route near the Omani coast under American guidance, as Lloyd's List Intelligence logged 102 Hormuz transits in a week.
QatarTanker operators are still moving oil through the Gulf, but many now take a longer southern route near Oman's coast, guided by US forces.
Lloyd's List Intelligence counted 102 Hormuz transits in the reported week: the strait is not closed, but shipping is not running normally either.
US ambassador Tom Barrack said the Golden Global designations are aimed at named institutions rather than Turkey's banking system, in a translated paraphrase carried by Euronews Turkiye.
US ambassador Tom Barrack said, through a Turkish broadcaster's translated paraphrase, that the Golden Global sanctions target the three named firms, not Turkey's whole banking system.
That message was aimed at reassuring Turkish banks generally rather than adding any new fact to the case itself.
David Osler, marine insurance editor at Lloyd's List, put cumulative war-risk claims across the conflict at roughly $2bn as of 3 September.
FranceDavid Osler, marine insurance editor at Lloyd's List, estimated on 3 September that war-risk claims across the conflict have reached about $2bn.
That is a running total, not one ship's cost, and insurers build a loss run this size into what every shipowner pays to sail the region.
The next confirmed IRGC strike on a US vessel decides whether CENTCOM holds the three-for-two rate, exceeds it, or backs off it; that attack, dated and named, is the mechanism that would tip the pattern either way. Admiral Cooper's ratio, the most explicit exchange rate CENTCOM has stated in the 2026 campaign, has been applied only once, on the day it was announced, so whether it holds is the open question, not a settled finding.
