Five ships crossed the Strait of Hormuz on Saturday. None were scheduled to on Sunday.
That is the entire visible flow through the waterway that once carried a fifth of the world's oil, according to Kpler data cited by Reuters. And yet Brent crude did not double. It did not even spike toward the triple digits traders once feared. It has spent Monday hovering near multi-week highs, briefly testing resistance before easing back, OilPrice.com reported — a market behaving as though the chokepoint were merely inconvenienced, not throttled.
The gap between what the strait shows and what the price says is the story. Somewhere between the empty transit lane and the calm futures curve sits an armada nobody is supposed to see.
The fleet hiding in plain sight
Off the coast of Oman, roughly 150 vessels are floating in waters that held about 40 in January, according to satellite data from the European Union's Sentinel-1 program cited by Bloomberg. Many are waiting for cargo transfers from vessels that are ferrying oil through the strait undetected before offloading it onto tankers idling in the Gulf of Oman. The mechanics are almost mundane: a laden tanker slips through Hormuz with its transponder dark, meets a second ship waiting outside, and hands off the crude before turning back for another run. Repeat enough times and you have replaced a blockade with a relay race.
The trade is running at full tilt despite recent attacks on vessels, people with knowledge of the shipments told Bloomberg. Barrels from the UAE, Iraq, Qatar and Kuwait have all moved this way, according to vessel-tracking data compiled by Bloomberg, Kpler and Vortexa. One Ukrainian outlet, citing the same reporting, put the scale at shipments by "dark" vessels exceeding an estimated 4 million barrels per day — enough oil to supply Germany and France combined, moving through a strait that is, on paper, a ghost town.
It isn't only crude. Satellite images from the Copernicus Sentinel-2 program showed two LNG tankers conducting a ship-to-ship transfer outside the Strait of Hormuz, with the vessel LNG Enugu anchored parallel to a second ship near the Omani city of Sohar over the weekend. Even the super-chilled cargoes that supply Asian and European power plants are now running the same relay as crude.
The tactics keep evolving. Where tankers once went dark for a few hours crossing Hormuz in the war's early weeks, supertankers are now going dark for longer stretches to move oil through both Hormuz and Bab el-Mandeb, doubling down on tactics honed earlier in the conflict since transponders first started switching off in late February. Some ships hug Oman's coastline on the way out, a route that is generally receiving assistance from the U.S. military while transiting — a quiet admission that Washington has effectively become the strait's shadow escort.
Aramco's own workaround is fraying
The kingdom that has the most riding on Hormuz staying open is discovering that its backup plan has a backup problem. Saudi Aramco has spent the war routing crude through Yanbu, its Red Sea port fed by the East-West pipeline, a route with roughly 7 million barrels a day of pipeline capacity but far less actual loading capacity at the port itself, according to Argus Media. It is, in Aramco chief executive Amin Nasser's own words, the industry's response to "the biggest crisis the region's oil and gas industry has faced."
Now Yanbu itself looks exposed. Asian refiners are pushing back against Aramco's request that they pick up oil at Yanbu because shipowners are struggling to find vessels willing to sail through the Red Sea, where Iran-backed Houthi militants have attacked tankers and energy infrastructure. Some buyers have asked instead to collect cargoes at Egypt's Mediterranean port of Sidi Kerir, according to trading sources cited by Bloomberg and reported by OilPrice.com — a detour so long that at least one refiner is weighing whether to abandon its monthly allocation entirely rather than eat the extra shipping cost around Africa. Separately, Reuters reported Monday that Aramco has begun offering Arab Medium and Arab Heavy crude for pickup at Fujairah, on the Gulf of Oman side, to some Asian buyers — yet another patch stitched onto a route that was itself a patch.
Every fix, in other words, is generating its own workaround. The strait closes, so cargo moves to Yanbu. Yanbu grows risky, so buyers ask for Sidi Kerir. Sidi Kerir costs too much, so a term contract gets shelved. Each layer buys time and costs money, and none of it shows up on the vessel count published each morning by Kpler.
Energy stocks have registered the calm rather than the strain. The Energy Select Sector SPDR traded at $61.91 as of Friday's close, up +1.39% on the session, with its 14-day RSI at a stretched 67.6 — a market pricing in continuity, not crisis. WTI crude settled at $82.41/bbl a barrel, Brent at $88.59/bbl, both up on the day but nowhere near levels that would signal an actual supply cutoff.
That calm is rented, not owned. The shuttle trade depends on insurers still willing to write cover, satellites happening not to catch every transfer, and Iranian forces choosing, so far, not to target the relay ships directly. Windward and Kpler count the barrels that surface. Nobody is counting the ones that don't. The strait may look empty from a shipping tracker in Singapore. From a satellite over Oman, it looks like the busiest patch of water in the Gulf.
