Houthi Seizure of Mayun Island Puts 12% of Global Trade at Risk

For defense planners and maritime-security analysts, the Houthi capture of Mayun (Perim) Island is a textbook anti-access/area-denial escalation, not a minor territorial footnote. A non-state actor now holds terrain overlooking a roughly 20-mile-wide strait, able to pair drones, anti-ship missiles, and mines with persistent observation of one of the world's busiest waterways. The immediate question is force posture: how much surveillance, escort, and freedom-of-navigation capacity the United States and allies must commit to keep 12% of global trade moving through Bab el-Mandeb.

Yemen's Iranian-backed Houthi rebels have seized Mayun Island, also known as Perim, a strategically located strip of land at the entrance of the Red Sea that sits astride the Bab el-Mandeb Strait. The capture was confirmed by a senior military official with Yemen's internationally recognized government and by a Houthi official, both speaking anonymously because they were not authorized to talk to journalists. The island's location gives whoever controls it a direct vantage point over one of the world's most consequential maritime chokepoints: roughly 12 percent of global goods normally transit the Bab el-Mandeb between the Red Sea and the Gulf of Aden, and the strait is the front door to the Suez Canal for Asia-Europe container traffic and Gulf energy exports.

Since the Iran war disrupted shipping through the Strait of Hormuz, Saudi Arabia has leaned on the Red Sea as an alternative export corridor, feeding the East-West pipeline to the Red Sea terminal at Yanbu.

The seizure matters most because it compounds an already degraded maritime security picture. Since the Iran war disrupted shipping through the Strait of Hormuz, Saudi Arabia has leaned on the Red Sea as an alternative export corridor, feeding the East-West pipeline to the Red Sea terminal at Yanbu. With Hormuz under pressure on one flank and the Bab el-Mandeb now contested on the other, the kingdom's two principal maritime export routes are simultaneously exposed. Houthi military spokesperson Yahya Saree attempted to narrow the threat in a Friday statement, claiming that 'maritime navigation is safe for all companies except for Saudi vessels.' Markets have not treated that as a credible guarantee. Experts described the Houthis as highly unpredictable, and the group's track record of drone, missile, and sea-mine attacks on commercial shipping since late 2023 argues against relying on a self-declared exemption.

The economic transmission mechanism is already visible. Saudi Arabia said Friday it had shut down the major cross-country East-West pipeline as a 'precautionary measure' following attacks the previous day. The Saudi Energy Ministry did not attribute the attacks, but the pipeline closure, even if temporary, removes a vital redundancy at the precise moment demand for non-Hormuz export routes is highest. The International Energy Agency has tracked Saudi oil exports through the Red Sea port at the pipeline's terminus, underscoring how much of the kingdom's export capacity now hinges on a corridor that is no longer secure.

The conflict is also widening geographically. In a statement early Saturday, the Iraqi government said Prime Minister Ali al-Zaidi ordered an investigation into the operations command in Maysan province and dismissed its commander after authorities determined that attacks targeting Saudi Arabia were launched from a site in the province. That finding points to third-party launch sites and proxy dynamics extending beyond Yemen, raising the risk that the Red Sea crisis becomes entangled with broader regional escalation. Separately, United Nations spokesperson Farhan Haq confirmed that Houthi rebels in the coastal city of Mokha seized a compound that had housed U.N. staff; all personnel fled safely before the city's capture, and no U.N. personnel remain in Mokha.
