1. The Blockade Has a Business Model
If your 2027 planning assumes a Middle East ceasefire puts energy and freight costs back where they were, the last two weeks argue otherwise. Iran is turning the disruption into a revenue line, and the routes around it are being closed.

US Central Command spent Thursday and Friday knocking down Iranian state-media claims that a sanctioned tanker and an Iranian containership had broken through the Strait of Hormuz blockade on July 30, and that the Islamic Revolutionary Guard Corps had destroyed three F-35s. Neither happened. CENTCOM describes its enforcement, more than 20 warships and hundreds of aircraft, as "America's steel wall," and its count since enforcement resumed in mid-July runs to 20 commercial vessels redirected, 2 disabled, and 2 boarded. Windward, an independent maritime-tracking firm, corroborated the denials, showing the Iranian containership reversing course at the edge of the blockade zone on July 30.
The more important development is what happened to the route around the strait. Saudi Arabia's answer to Hormuz risk has always been the East-West Pipeline, which carries crude across the country from the oil fields of the Eastern Province, on Saudi Arabia's Persian Gulf coast, to the Red Sea terminal at Yanbu, on the kingdom's west coast north of Jeddah. The pipeline can move roughly 7 million barrels a day, about 5 million of it available for export. Since March, that bypass has carried the load: Red Sea port exports averaged 4.7 million barrels per day from March through June, nearly triple the 1.6 million of a year earlier. Nearly all of that oil then has to pass through the Bab al-Mandeb strait, the narrow gap between Yemen and the Horn of Africa where the Red Sea empties into the Gulf of Aden and the Indian Ocean beyond it. It's the only way out for anything shipped from Yanbu, and Houthi forces in Yemen sit on one side of it.
Over the weekend of July 25, Iran-backed Houthi forces struck Yanbu and the Jizan refinery, a Red Sea facility near Saudi Arabia's border with Yemen; Aramco confirmed the Jizan shutdown two days later. The Houthis framed the strikes as retaliation for Saudi airstrikes in Yemen, their own war and their own stated motive. But look at the target selection. Neil Quilliam of Chatham House described it as "targeting the safety valve rather than the heart of the production system." Nobody tried to destroy Saudi oil production; the strikes closed the one route built to escape the strait. A separate strike hit Aramco's Abqaiq stabilization complex, on the other side of the country near the Persian Gulf coast, Saudi Arabia's largest single facility and the same one a 2019 drone attack knocked offline, spiking oil prices 20 percent in a day. Abqaiq processes roughly 7 million barrels a day at full capacity. Nobody has confirmed damage anywhere near that scale this time, and oil prices haven't moved as if it happened either. Jizan's 400,000-barrel-per-day refinery is down, with a mid-August restart cited by third-party estimates, not yet confirmed by Aramco.
Meanwhile, the strait itself has acquired a price list, of a kind. The Revolutionary Guard has been charging roughly $2 million per vessel for passage without an IRGC attack, and Iran's parliament is moving to formalize the toll as a standing system rather than a wartime improvisation. But paying Iran doesn't clear the other gate. The US Navy enforces its blockade independently, intercepting vessels in the Gulf of Oman on the far side of the strait regardless of what Tehran has already approved. The Rich Starry, a Chinese-owned tanker previously sanctioned for smuggling Iranian oil, loaded cargo and transited the strait in July after apparently squaring things with Iran, then reversed course back toward Iran's coast the next day once the US Navy caught up with it beyond the strait. A separate, not-yet-agreed proposal for a joint Iran-Oman levy of roughly $1 per barrel is what Oxford Economics estimates could generate $6.8 billion a year if it goes forward, comparable to the roughly $4.7 billion Egypt earns annually from the Suez Canal. Nobody has published a reliable estimate of what the IRGC's own toll is actually generating, and Iran has an obvious incentive to inflate the number: a toll that works is a much better story than a toll that doesn't guarantee anything.
None of that revenue math is verifiable from the outside, and Iran has every reason to inflate it. Its Oil Ministry reports hitting 60 percent of the full-year oil-revenue target in the opening months of the Iranian fiscal year, which began in late March: $18 billion in total, $11.5 billion of it earned under active war conditions, with about $11 billion transferred to the treasury. Treat those figures with real skepticism. But the message itself is worth reading: Tehran is telling its own public, and by extension everyone else, that confrontation pays, even while the traffic data suggests the toll is more of a story than a functioning system.
Nobody has to prove Iran ordered the Houthi strikes for the math to hold. The Houthis have their own reasons to hit Saudi Arabia, and there's no evidence of direct Iranian command. What matters is who benefits when the routes close. A cargo that can't use the bypass either sits and waits, pays Iran's toll and still might not get through, or moves at a higher price because less oil is reaching the market. Every one of those outcomes helps whoever has already priced the chaos into its own budget. Whoever gave the order, Iran collects.
