Yemen’s Houthis seized Perim Island (Mayyun) in the Bab al-Mandeb Strait on or around September 10-11, 2026, during a rapid coastal offensive that also captured the port of Mocha and nearby towns including Dhubab. Government-aligned forces withdrew, allowing Houthi fighters to occupy the island at the narrowest point of the vital shipping lane. This development followed months of preparation and occurred amid broader regional tensions involving Iran, Saudi Arabia, and disruptions near the Strait of Hormuz. Control of Perim enhances the group’s ability to monitor or influence maritime traffic, though Houthi statements have claimed safe passage for most vessels except those linked to Saudi Arabia. Potential shifts in control could stem from Saudi-backed counteroperations, international naval involvement, diplomatic negotiations, or further escalation in the Yemeni conflict, with any reversal likely requiring coordinated military or political pressure given the island’s strategic position.

“The Houthis” refers to the Houthi movement (Ansar Allah), including its governing institutions and any armed force operating under its direction or on its behalf. “Perim Island” refers to Perim (Mayyun) Island in the Bab el-Mandeb Strait, Yemen.
“No longer under the control of the Houthis” means that the Houthis no longer exercise primary military control over Perim Island, and another state, occupying force, the internationally recognized government of Yemen, or an internationally backed authority has established control over the island.
Temporary raids, isolated landings, special operations, bombardment, sabotage, naval presence offshore, or temporary disruption of Houthi activity will not qualify on their own.
An announcement, threat, or claim that the Houthis have lost control will not qualify without actual control being established.
If control changes pursuant to a negotiated settlement, ceasefire term, surrender, or transfer agreement, this will qualify only once actual control has been established on the island.
If control over Perim Island is contested, unclear, disputed, or not sufficiently established by the resolution date, this will not qualify, and the market will resolve to “No”.
The primary resolution source will be official statements from the relevant governments and militaries, along with a consensus of credible reporting.
