Hormuz Shipping Choked to Seven Vessels as IRGC Hits U.S. Sea Drone, Bab al‑Mandab Slips Under Houthi Control
Ship traffic through the Strait of Hormuz dropped to just seven vessels on Thursday, while Iran’s Revolutionary Guard struck a U.S. sea drone and Houthi forces entrenched control around Bab al‑Mandab. Together, the moves tighten a noose around global energy and trade routes that carry a large share of the world’s oil and container traffic.
Global shipping is being squeezed at both ends of the Arabian Peninsula. Vessel traffic through the Strait of Hormuz fell to just seven ships on Thursday, far below typical flows, as Iran’s Revolutionary Guard struck a U.S. sea drone in the waterway and Yemen’s Houthi movement consolidated control over the Bab al‑Mandab Strait at the Red Sea’s southern mouth.
Ship‑tracking data on 11 September showed only seven vessels transiting Hormuz, one of the world’s most critical energy arteries. The falloff follows weeks of missile, drone, and harassment incidents tied to the war between Iran and its adversaries, leaving shipowners, charterers, and insurers weighing whether passage is worth the risk. The U.S. Fifth Fleet and allied navies have increased patrols, but the numbers suggest fewer captains are willing to bet their hulls and crews on deterrence alone.
Iran’s Islamic Revolutionary Guard Corps struck a U.S. sea drone in the strait, according to a report from regional media. Sea drones—uncrewed surface vessels used for surveillance and, increasingly, for offensive missions—have become a flashpoint at sea. For Tehran, hitting one on its doorstep sends a message about contested control of the narrow channel; for Washington, it raises questions about how much intelligence and presence it can maintain without escalating to direct clashes between crewed ships.
Further southwest, the Houthis are tightening their grip on the other key maritime gateway. Citing Yemeni officials and regional reporting, Al Jazeera and Agence France‑Presse said Houthi forces have completed control over the city of Dhubab and captured Perim (Mayun) Island, which sits at the center of the Bab al‑Mandab Strait. Footage shows a Houthi operative outside the Dhubab administration building, presented as proof of the takeover. Separate footage shows Houthi fighters operating somewhere near the strait itself.
For ship crews, Bab al‑Mandab is not an abstract map feature. The narrow passage connects the Red Sea to the Gulf of Aden and onward to the Indian Ocean; it is the southern gate to the Suez Canal route that carries a large share of Europe‑Asia container and energy traffic. A hostile force entrenched on both the Yemeni coast and Perim Island has the tools, at least in theory, to threaten or interfere with ships using that route, whether through direct attacks, boarding, or the threat of mines.
The economic stakes run far beyond a handful of tankers. Hormuz carries a significant share of global seaborne crude and liquefied natural gas exports from Gulf producers, while Bab al‑Mandab links Europe’s markets to Asian manufacturing and Middle Eastern oil. When operators slow or re‑route traffic, cargoes arrive late, freight rates jump, and some buyers find their orders repriced or deferred. For energy importers facing high prices and tight supplies, a double chokepoint squeeze can quickly become an inflation shock.
Strategically, Iran’s confrontation with the United States and its regional rivals is now visibly playing out on the water. By hitting U.S. unmanned systems in Hormuz and enabling or tolerating Houthi advances on the Red Sea front, Tehran tests how far it can push without triggering a coalition naval response that goes beyond defense. Western and regional navies can escort some traffic, but they cannot escort everything, all the time.
What’s emerging is a world where risk at sea no longer needs a formal blockade to change behavior. Hormuz does not have to close, and Bab al‑Mandab does not need to be mined end‑to‑end, for shipping executives and underwriters to reroute at scale. Persistent, credible danger in a narrow lane is often enough.
The critical indicators to watch next are whether Hormuz traffic recovers above single‑digit transits, whether any major shipping line or energy company publicly suspends use of the Suez–Bab al‑Mandab route, and how the United States and its partners respond to the IRGC’s strike on their sea drone. A decision to deploy more escorts or to target shore‑based launch sites would signal a harder line—and higher stakes—for everyone who depends on oil and goods moving through these straits.
