You can't talk about global trade right now without looking at a tiny volcanic rock off the coast of Yemen. Mayun Island, also known as Perim, sits right in the middle of the Bab al-Mandeb Strait. When the Iran-backed Houthis seized control of it alongside the port city of Mokha, they didn't just win a local skirmish against Saudi-backed government forces. They grabbed a chokehold on one of the most critical commercial waterways on Earth.
If you're wondering whether they can actually hold this strategic position long-term, you have to look past the headlines and examine the ground reality of Yemen's shifting military balance.
The Anatomy of a Chokepoint
The Bab al-Mandeb Strait is the southern corridor connecting the Red Sea to the Gulf of Aden. At its narrowest point, it's only about 20 kilometers wide, and Mayun Island splits that channel into two distinct paths. Control the island, and you basically control the traffic moving through the corridor.
This isn't happening in a vacuum. With the Strait of Hormuz facing severe disruptions and closures following the wider regional conflict involving the US and Iran, global energy markets started relying heavily on Saudi oil exports moving through the Red Sea and the Suez Canal route instead. About 12 percent of global trade and a massive share of crude oil move through this exact region.
By taking Mokha first and then pushing onto Mayun Island, the Houthis have effectively secured the entire western coastline of Yemen. They've built an operational perimeter that gives them direct physical leverage over international shipping.
Can the Houthis Actually Keep It?
Military analysts are split, but holding Mayun Island comes down to logistics, air defense, and regional politics.
For years, the United Arab Emirates and Saudi-backed coalitions maintained a heavy footprint on the island, even building an airstrip there back in 2021. But when the UAE withdrew its forces, the defensive architecture left behind became vulnerable. The Houthis moved fast, catching local military commanders off guard.
According to sources within Yemen's internationally recognized government, a massive breakdown in coordination and a lack of immediate air support from Saudi jets allowed the rebels to sweep through the coast almost unchecked. Some military insiders claim Washington didn't give Riyadh the green light for a heavy counter-offensive campaign, leaving the local anti-Houthi forces high and dry.
Now that they are on the island, the real test begins. The Houthis face serious challenges if Saudi Arabia or other regional actors decide to launch an amphibious or heavy air-striking campaign to dislodge them. Mayun is small—only about 13 square miles—making any occupying force an easy target for sustained aerial bombardment unless they bring in robust anti-air capabilities.
Tehran's Calculated Play
You cannot separate this move from Iran's broader strategy. Tehran gains immense leverage through this escalation. With Hormuz restricted on the other side of the Arabian Peninsula, having an aligned proxy control the entrance to the Red Sea gives Iran a dual-chokepoint strategy.
When the Houthis declare a naval blockade or restrict specific vessels—claiming general shipping is safe except for Saudi-linked traffic—they are executing a playbook written in coordination with Iranian objectives. It forces Washington and its allies to negotiate on multiple fronts simultaneously. Iran wants diplomatic pressure lifted and its own economic blockades challenged, and the Houthi advance on Mayun provides a fresh bargaining chip.
What Comes Next for Global Supply Chains
For businesses and consumers, this means supply chain instability is here to stay. Shipping companies are already recalculating risk premiums. If insurance rates for the Red Sea spike again, cargo costs will follow immediately.
The fragile truce that held Yemen's civil war in check since 2022 has completely fractured. With over 46,000 people fleeing the recent surge in fighting around Mokha and the coastal towns, a full-blown humanitarian crisis is compounding the geopolitical risk.
Keep a close eye on whether regional coalitions mount a counter-offensive to retake Mayun Island before the Houthis dig in permanently. If they manage to fortify the island with radar and missile batteries, the Red Sea will remain under rebel oversight for the foreseeable future.
