Three separate claims were made about the Strait of Hormuz in the past forty-eight hours. One was confirmed in an official statement by the body that carried out the action. The second was posted alongside two AI-generated videos, and there is no report that the event it describes occurred. The third came from a belligerent party, with no vessel named and no details about the crew.
A barrel of Brent is trading as these lines are written at $90.43, up 2.65% on the day.
A price has to be set even when this is the state of knowledge. This piece separates the three claims.
Errors or inaccuracies are possible. Spotted something that looks wrong? Write to me and I will correct it.
The First Claim, and the Only One With an Official Statement From the Actor
On Sunday US forces struck two rocket launchers on Larak, a small island sitting inside the Strait of Hormuz. It is the first confirmed US strike on Iran in more than a month.
US Central Command said this was limited, precise action against a Revolutionary Guards force observed preparing to launch rockets carrying sea mines into the strait. In a further statement the command rejected the Guards' characterisation of the action as an "act of aggression", calling that description absolutely false.
The Iranian response came the following day. The Revolutionary Guards fired ballistic missiles at two US bases in Jordan; the Jordanian military said it intercepted eight missiles that entered its airspace. Drone attacks were also reported on Al Minhad Air Base in the United Arab Emirates, along with an Iranian claim to have downed a US drone over the strait.
For the oil market, the material detail in that whole paragraph is sea mines. It is the only physical mechanism here capable of stopping tanker traffic, and the only one that does not depend on anyone's statements.
Why a Claim About Kharg Is an Entirely Different Story
To see why the second claim matters, you have to know what Kharg is.
| Kharg Island | |
|---|---|
| Share of Iranian exports passing through it | about 90% |
| Loading capacity | 7 million barrels a day |
| Storage capacity | 30 million barrels |
| Distance from the Iranian coast | about 30 kilometres |
| Main destination before the fighting | China, about 80% of shipments |
Larak, by comparison, is a base. Secondary storage and transfer, and above all a principal naval and logistics facility of the Revolutionary Guards - fast boats, missile systems and mine infrastructure.
The difference between the two is the difference between military infrastructure and export infrastructure. A strike on Larak changes the balance of force in the strait. A strike on Kharg changes how much oil exists in the world.
The Second Claim: The Video
On Sunday night the US president posted on his social network the line "Kharg Island being blown to smithereens!!!" - alongside two AI-generated videos showing an aerial attack on storage tanks, on tankers and on coastal oilfields.
There is no report that Kharg was struck.
The US strike that was reported took place at Larak, roughly 400 miles from Kharg. Kharg sits deep inside the Persian Gulf, to the north-west of the strait.
The White House and the Department of Defense declined immediate comment on the post.
I do not know what lay behind the posting, and I do not pretend to. What I will say is this: the most dramatic of the three claims is the only one with no corroboration at all, and it is the one that arrived accompanied by video.
The Third Claim: A Tanker With No Name
On Monday the Revolutionary Guards said, via Iranian state television, that a supertanker had struck two sea mines in the southern strait, caught fire and come to a stop. The statement said the vessel had been attempting to transit the waterway unlawfully.
The statement did not name the vessel and gave no details about the crew.
And this claim carries a context that makes it more interesting still: it came only days after the US president stated that all mines laid by the Revolutionary Guards in the strait had been cleared, and that any ship laying new mines would be destroyed.
Two contradictory claims about the same stretch of water, from two belligerent parties, days apart.
The Three Claims, Side by Side
| The claim | Source | Verification status |
|---|---|---|
| Strike on launchers at Larak | US Central Command | Official statement by the actor |
| Kharg has been destroyed | Presidential post, with AI-generated video | No supporting report; no official comment |
| A tanker struck two mines | Revolutionary Guards | No vessel named; not independently verified |
I am not asserting that the latter two claims are false. I am asserting something narrower and checkable: they are not at the same level of verification as the first, and yet they bear on the same price.
And here something easy to forget is worth saying: absence of confirmation is not refutation. A tanker that was hit may be entirely real and may be confirmed tomorrow morning. Distinguishing between degrees of verification is not a ruling on who is right - it is only a refusal to treat all three as one thing.
What the Price Did, and Where It Came From
The easiest thing to miss in the market's response is not the rise, but what preceded it.
| Brent | |
|---|---|
| At the last close before the weekend | $89.30 |
| Change over that week | a fall of more than 5% |
| On 31 August | $90.43, up 2.65% |
The market fell before it rose. Over the week preceding this weekend oil lost more than 5%, on a view that the confrontation with Iran had become a matter of sanctions and economic pressure rather than an immediate threat to physical supply. Flows through the strait had improved, and an alternative route via Oman was under discussion.
In other words: just as the market finished pricing out the supply risk, the events returned.
And the Numbers That Do Describe Supply
Against the claims, it is worth looking at the quantities themselves.
| Iran's oil exports | |
|---|---|
| February 2026 | 1.98 million barrels a day |
| August 2026 | 135,000 barrels a day |
That decline preceded the weekend's events and is a result of the US naval blockade, reimposed in mid-July after an interim arrangement mediated by Pakistan collapsed.
And here is the wider context: on Goldman Sachs' estimate, oil exports from the Persian Gulf as a whole now stand at roughly 15 to 16 million barrels a day. Before the fighting they stood at 22 to 24 million, and at the March low they fell to about 5 to 6 million.
So the region has recovered from most of the damage, but is still short some six to nine million barrels a day against the pre-war position. That is the context into which every new report lands.
הזווית שלי
דעה אישית של אילן אברמוב - לא ייעוץ ולא המלצה
I wrote here two days ago about the difference between a price move with barrels behind it and a price move with an expectation of barrels behind it. Today added a layer I did not have in mind: an expectation generated by a synthetic media asset.
And I want to be precise in the claim, because it is easy to overstate. I am not arguing that today's rise is caused by the video. I cannot know that, and there are entirely real reasons for the price to rise - a US strike, missiles fired at Jordan, and mines reported as prepared for launch. Those are quite sufficient on their own.
What I am arguing is narrower, and in my view more important: in the basket of information from which today's oil price was set, there is also an item generated by artificial intelligence. Not as a rumour passed along, but as a video file showing the thing it asserts.
The difference between the two is not semantic. A rumour asks the reader to believe someone. Video asks him to believe his own eyes, and that is a mechanism which has failed far fewer times across history, which is exactly why resistance to it is weaker.
So the tool I am trying to practise on myself on days like this is simple and dull: before asking whether a report moves a price, ask who reported it and what its verification status is. The three claims of the past two days differ from one another precisely in that field, and the difference between them is not visible on a chart.
And what I will track is the least dramatic item of all: the number of tankers actually loading. That is a figure you can count, it does not depend on any party's statements, and it is the only one that ultimately moves oil.
(It is important to stress: this is my personal opinion only, and nothing herein constitutes a recommendation to take any action.)
