A week after declaring the blockade of Saudi Arabia, the Houthis were reported to be weighing transit fees on ships passing the Bab al-Mandeb. The reporting placed the origin of the idea in Tehran, raised during a Houthi delegation’s visit in July, with Iranian advisers said to be helping stand up an authority to administer the charges. The Houthi-run Humanitarian Operations Coordination Center denied it within days, describing its safe-transit service as voluntary and free, and warning shipping companies not to pay or share vessel information with anyone claiming to collect on Yemen’s behalf.
Why the denial is interesting
The HOCC statement did more than reject the report. It pre-emptively delegitimised any collector who might appear, which is what an organisation says when it expects imposters, and it is also what an organisation says when it wants deniability for a pilot scheme run through an intermediary. Both readings are available. What is clear is that Sanaa understands the legal exposure: a state or quasi-state that charges for passage through an international strait is doing something UNCLOS does not permit, and the moment money changes hands the campaign loses its framing as a reciprocal siege and becomes extortion in the eyes of every flag state.
The Hormuz template
The mechanism has a precedent one theatre away. Iran’s proposed transit arrangements for the Strait of Hormuz, and the Iran-Oman corridor talks that include consideration of a toll, are an attempt to convert control of a waterway into a recurring revenue stream with an administrative face. Tehran has an obvious interest in the same architecture appearing at the southern end of the Red Sea. A fee authority at the Bab al-Mandeb would give Iran and its partners a matched pair of tollbooths on the two chokepoints that carry Gulf crude to Europe.
The economics favour it. Saudi Arabia has leaned on Red Sea routing precisely because Hormuz is disrupted, which means a Bab al-Mandeb toll lands hardest on the state the Houthis are already trying to squeeze. A fee also converts a campaign that costs the group money in expended missiles into one that generates cash, and it creates a bureaucracy with a payroll, which is the sort of thing that survives ceasefires.
Indicators that a fee regime is real
The first observable will not be an announcement. It will be a P&I club circular, or a charter party clause, referring to payments to a Yemeni entity. Watch for the appearance of a named authority with a bank relationship outside Yemen, for brokers reporting quiet quotes on “transit facilitation”, and for a divergence between vessels that transit unmolested and vessels of comparable profile that are engaged. Selective immunity is the signature of a protection racket in its early stage, and it shows up in incident data before it shows up in any document.
The second observable is the reaction of the shadow fleet. Operators moving sanctioned cargo already pay for discretion and already operate outside the insurance mainstream. They are the natural first customers, and their transit numbers holding steady while mainstream tanker transits fall would be consistent with a two-tier passage market forming.
