Yemen’s Iran-aligned Houthi forces captured the strategic volcanic island of Perim—also known as Mayun—in the Bab al-Mandab strait. This critical geopolitical advance expands Houthi control over a vital global oil and shipping bottleneck linking Asia and Europe, intensifying security concerns across Western capitals and energy markets.
Energy markets have felt the immediate impact of this strategic shift. Oil prices climbed past $100 a barrel as fighting across Yemen’s west coast escalated through the week, culminating in the loss of the port city of Mocha on Thursday, according to reporting from the Guardian.
Here is why that matters: about 12 percent of the world’s goods pass through the Bab al-Mandab strait. With the Houthis consolidating power along the Red Sea coast, anti-Western forces have strengthened their chokeholds on global maritime choke points.
Shifting Controls Across the Bab al-Mandab Strait
The fall of Perim island occurred after forces loyal to the UN-backed, Aden-based government abandoned their positions. This retreat followed a series of rapid military reverses along Yemen’s western seaboard. Saudi Arabia, which bankrolls and supports the official Yemeni government, responded with airstrikes targeting Houthi positions in Mocha on Friday.
Control of Perim island carries immense strategic weight. The volcanic landmass divides the narrow Bab al-Mandab strait into two channels near its tightest point. Previously, the United Arab Emirates—a former Saudi ally in the anti-Houthi coalition—had been building an airbase on the island before winding down its active involvement in the conflict in January.
Saudi Arabia has grown increasingly reliant on Red Sea shipping routes to export its crude oil. This pivot became necessary as Iran has been targeting vessels in the Strait of Hormuz. Full Houthi dominance over the Red Sea passage, alongside Iranian control of the strait of Hormuz, effectively places both major Middle Eastern energy bottlenecks under the influence of anti-western forces.
| Strategic Asset | Location | Recent Development |
|---|---|---|
| Perim Island (Mayun) | Bab al-Mandab Strait | Captured by Houthi forces following government troop withdrawals. |
| Mocha Port | Yemen West Coast | Seized by Houthi forces; targeted by Saudi airstrikes on Friday. |
| Strait of Hormuz | Persian Gulf / Oman | Subject to proposed temporary shipping routes under Iranian influence. |
Geopolitical Fallout and Diplomatic Calculations
Iran formally praised the Houthi advances in an official statement on Friday, marking Tehran’s first extended commentary on the renewed hostilities. The territorial gains strengthen Iran’s diplomatic hand as regional powers prepare for upcoming diplomatic talks.
Foreign ministers from the Gulf Cooperation Council (GCC) are scheduled to meet in the Omani coastal city of Salalah on Monday. Discussions are expected to center on a proposed framework involving temporary approved shipping routes largely under Iranian influence. If adopted, the arrangement could pressure the United States to lift its blockade of Iranian oil ports.
But there is a diplomatic catch for Western policymakers. British diplomatic sources indicated that London does not expect Donald Trump to sanction direct American military intervention or bombing campaigns in Yemen, despite requests from Saudi Arabia. Meanwhile, the human toll of the offensive continues to mount. The UN migration agency reported that the recent fighting has cost more than 500 lives and displaced approximately 46,000 people.
The Risk to Regional Stability
The rapid pace of the Houthi advance has left foreign ministries across Western capitals deeply anxious about the longevity of the UN-backed government in Aden. Past ceasefires, such as the surprise arrangement brokered in May 2025, relied on private assurances from Houthi leadership regarding commercial shipping safety.
As diplomatic delegations gather in Oman and energy traders recalibrate risk premiums, the redrawn map of Yemen signals a profound shift in regional power dynamics. The security of global supply chains now rests precariously on fragile negotiations and the shifting ambitions of armed factions along a volatile coastline.
