Houthi Advance Along the Red Sea Coast Raises New Threats to Saudi Shipping and Global Trade
By Drooid · · How we work
Core Event
In early September 2026 the Iran-backed Houthi rebels launched an offensive that seized the Yemeni port of Mokha, Perim Island and several smaller islands at the mouth of the Bab el-Mandeb Strait. By mid-month the group controlled the Yemeni Red Sea coastline and announced it would target only Saudi-linked vessels, while assuring U.S. ships would not be attacked. The move follows a ballistic-missile strike on Riyadh over the weekend and an Iraqi Shi’ite militia drone attack on Saudi Arabia’s East-West pipeline on September 10.
Background & Context
The Houthis have fought the internationally recognised government since seizing Sanaa in 2014. A UN-brokered truce in 2022 held the front lines relatively static until July 2026, when Saudi-backed forces struck Sanaa airport’s runway. The Houthis cited that strike as a trigger for their September offensive. Their control of Bab el-Mandeb—through which roughly 12 % of global trade passes—gives them leverage over Saudi oil exports, especially as the Strait of Hormuz remains disrupted.
Data & Statistics
- Territorial gains: Mokha, Perim Island, the Greater and Lesser Hanish islands, Mayyun and the Zuqar archipelago are now under Houthi control.
- Maritime traffic: Reuters-cited Kpler data recorded 23 cargo ships transiting Bab el-Mandeb on September 17, down from an average of 26 in the preceding ten days.
- Human displacement: The UN estimates over 100,000 people fled the coastal offensive, many reaching Djibouti by boat.
- Casualties: Yemeni army claims more than 80 Houthi fighters killed near Marib, though figures are unverified.
Why It Matters / Impact
Control of Bab el-Mandeb allows the Houthis to threaten Saudi oil shipments that now rely heavily on the Red Sea corridor after the closure of the Strait of Hormuz. Disruptions raise shipping insurance premiums, force rerouting around the Cape of Good Hope, and could push Brent crude above $110 per barrel, according to energy analysts. African Red Sea states—Egypt, Djibouti, Ethiopia, Eritrea, Somalia and Sudan—face heightened economic risk from reduced transit fees and increased security costs.
Official Statements & Responses
- Kaja Kallas, EU High Representative for Foreign Affairs, said the EU’s Aspides naval mission has raised its alert level to protect commercial shipping, describing Houthi attacks on Saudi vessels as “unacceptable.”
- John Ratcliffe, CIA Director, met Egyptian President Abdel-Fattah el-Sissi, who expressed support for a deal to secure Red Sea navigation.
- Valentin d’Hauthuille, Middle East analyst at ACLED, noted the Houthis’ focus on “Saudi-linked shipping.”
Conflicting Reports & Gaps
Sources differ on the extent of the traffic decline through Bab el-Mandeb. Reuters/Kpler data (23 ships on September 17) suggest a modest reduction, while AP’s Windward shipping firm reported a drop to 25 daily transits followed by a rebound to 45, a figure not independently verified. Casualty numbers from the Marib clashes also remain uncorroborated.

What’s Next
The 81st United Nations General Assembly high-level week begins on September 22, where the Red Sea situation is expected to be a key agenda item. The EU’s Aspides mission will continue heightened patrols, and regional mediators—including Saudi Arabia, Turkey and Pakistan—have signalled willingness to discuss de-escalation, though no concrete diplomatic timetable has been announced.
