Fifteen ships a day are moving through the Strait of Hormuz. You just can’t see them.
That’s the blunt takeaway from a report that stopped traders mid-scroll on Monday. Citrini Research — a boutique firm that shook AI investors earlier this year with a bearish call on the sector — says it sent an unnamed analyst to Oman’s Musandam Peninsula, where the researcher took a boat to observe tanker traffic firsthand. The findings are inconvenient for the dominant market narrative: the strait isn’t a blockade. It’s a checkpoint.
Markets have been trading a binary. Either the Strait of Hormuz reopens and crude crashes, or it stays shut and oil goes parabolic. Citrini’s field report suggests both scenarios are wrong — and that the real trade is somewhere murkier in between.
What AIS Data Isn’t Telling You
Here’s where it gets interesting. AIS — the Automatic Identification System that ships use to broadcast their location, speed, and identity — is the backbone of every tanker-tracking dashboard that traders stare at. When AIS goes dark, ships disappear from the feed. Markets assume: no signal, no movement.
Citrini’s analyst found that assumption is wrong. Ships are transiting the strait, often with their AIS transponders switched off — what the maritime world calls “going dark.” Fishermen, smugglers, and regional officials on the ground painted a picture of a functioning, if tightly controlled, passage. Iran isn’t slamming the door. It’s charging admission.
“Tankers passing through four or five a day, completely dark on AIS,” the firm wrote on Substack. “The volume, they said, is higher than what the data suggests, and it’s been accelerating in the past couple days through the Qeshm channel.”
The Qeshm channel — a narrow passage hugging the Iranian coast — is the back door. Ships willing to seek Iranian clearance are using it. That creates a de facto checkpoint, not a closure. And that distinction matters enormously for how you price risk.
The “Functional Checkpoint” Thesis
Citrini’s framing is precise: what exists now is a “functional checkpoint” rather than a blockade. Tehran isn’t physically blocking passage so much as requiring tankers to obtain clearance before transiting waters near Iranian territory. That’s coercive, yes. It’s also not the same as welding the strait shut.
Before the war broke out on February 28th, an average of 20 million barrels per day of crude and products flowed through the strait. In March, tanker transits dropped to under two per day. As of Monday, S&P Global Market Intelligence put the number at 8 tankers — a significant rebound, though still a fraction of normal. Add in the dark ships Citrini’s analyst counted, and you start to get a fuller picture.
The firm estimates roughly 50% of pre-conflict traffic could be restored within four to six weeks. That’s not a reopening. But it’s also not the catastrophic supply seizure that $113 Brent crude prices might imply.
Oil at $113 — Pricing in the Wrong Scenario?
Brent crude sat at $110.36 a barrel on Monday night. WTI was at $113.46. Those prices are pricing in sustained, near-total disruption. Citrini’s report raises an uncomfortable question: what if the market has the wrong base case?
The firm isn’t calling for an oil crash. Far from it. Their view is that the disruption is real and lasting — but that a permanent risk premium, rather than a price spike driven by complete closure, is the correct framework. To express that view, they’re favoring December 2026 WTI futures over front-month contracts. The trade says: the disruption doesn’t end Tuesday, but the binary event risk is overpriced in near-term oil.
That’s a nuanced position. Wall Street doesn’t do nuance well when geopolitical fear is in the air.
Trump’s Tuesday Deadline and the Negotiation Backdrop
All of this plays out against a ticking clock. Trump reiterated Monday that Iran has until 8 p.m. ET on Tuesday to reopen the strait, threatening to bomb power plants and bridges if Tehran refuses. Iran rejected the U.S. ceasefire proposal and countered with a 10-point plan of its own — demanding a permanent end to hostilities, sanctions relief, and reconstruction aid.
Trump’s response: “They made a significant proposal. Not good enough, but they have made a very significant step.”
That language sounds more like a negotiation than a war briefing. Reuters reported that the U.S. and Iran are discussing a framework to end their five-week-old conflict, with several countries playing intermediary. The odds of a ceasefire before tomorrow’s deadline are slim. But the fact that both sides are talking — and that ships are quietly moving through a back channel — suggests the strait’s situation is more fluid than the binary narrative implies.
The Citrini Factor
One more thing worth sitting with: Citrini Research is the same firm that made a bold, prescient bearish call on artificial intelligence earlier this year — a call that moved markets. They don’t do research for attention. Dispatching a human analyst to a conflict zone is expensive, logistically difficult, and carries genuine personal risk. That they did it at all says something about how seriously they’re taking this trade.
To be fair, the findings rest on a single field visit and anecdotal accounts from fishermen and regional officials in a zone where independent verification is nearly impossible. One data point doesn’t override satellite imagery, AIS aggregators, and Lloyd’s of London shipping data. The market should treat it as a signal, not a certainty.
But here’s the thing: the market was already trading a story. Citrini’s analyst just went to check whether the story was true. The answer, it turns out, is more complicated than either the bulls or the bears want to admit.
That’s usually where the real money is made.
