Houthis Take Mokha — And the Red Sea Shipping Crisis Deepens

The Ground Shift Matters More Than the Missiles

The Houthi takeover of Mokha is not the most dramatic territorial gain in Yemen’s decade-long war, but it is perhaps the most strategically consequential. The port city sits within sight of the Bab el-Mandab strait – the 20-mile-wide pinch point where the Red Sea meets the Gulf of Aden. Control of this coastline does not just give the rebels a new urban center. It gives them more coastline, more launch positions, and more options for a campaign that is already disrupting global shipping.

What distinguishes this moment from previous Houthi advances is the geometry of the threat. Gregory Johnsen of the Arab Gulf States Institute noted that the Bab el-Mandab acts as a funnel. When the Houthis held only northern coastal territory, their reach into the strait was limited. Moving south to Mokha shrinks the navigable space available to commercial vessels and expands the targeting landscape for Houthi missile and drone batteries. The rebels do not need to hold every inch of the strait to make it dangerous. They need only enough geography to disperse mobile launchers across a wider front – the same playbook Iran has used with varying success in the Strait of Hormuz.

Oil Prices Already Reacting

The market is pricing in the risk. Brent crude pushed above $105 a barrel on news of the advance, a sharp reminder that even tentative calm in Yemen carries a risk premium. The last four years of a U.N.-brokered truce kept that premium contained. With the truce effectively over, as U.N. special envoy Hans Grundberg warned, the floor under energy markets is moving higher.

The Houthis have so far framed their attacks as targeted against Saudi oil tankers. That is a narrow claim, but narrow attacks on narrow targets in a narrow strait add up. Insurance premiums for vessels transiting the Red Sea have already surged in prior months of Houthi activity. Any further deterioration – whether through direct strikes on tankers or the threat of them – will push those premiums higher and force more carriers onto longer routes around Africa’s Cape of Good Hope. The detour adds days to transit times and significantly increases fuel costs per container.

Why This Time Feels Different

Previous Houthi forays along Yemen’s coast did not produce the same strategic picture. In past rounds of fighting, the anti-Houthi coalition held the western coastline well enough to deny the rebels uncontested access to the strait. This time, the coalition collapsed quickly in Mokha. The militia responsible, led by Tareq Saleh, was considered one of the more capable Yemeni government allies. Its failure to hold the city signals deeper fractures than many analysts had been tracking.

Johnsen pointed out that the so-called anti-Houthi coalition is really eight to ten separate groups with opposing endgames. Saudi Arabia’s decision late last year to push the United Arab Emirates out of Yemen and absorb those militias into its own umbrella created a false sense of unity. The Houthis have spent years exploiting the fissures between these factions. Mokha’s fall is the latest example.

There is also a learned-behavior element. Johnsen observed that the Houthis have long tried pushing eastward toward Marib to seize Yemen’s inland oil and gas reserves, only to be repelled by Saudi airpower. What changed is that they studied Iran’s strategy in the Strait of Hormuz and decided to replicate a maritime chokepoint campaign instead. Rather than burning resources inland, they are moving south along the coast to control the Bab el-Mandab approach. The logic is simple: a coast they can hold beats oil fields they cannot.

The Iranian Shadow

Houthi spokesperson Mohamed A-Bukhai insisted there are no Iranian forces in Yemen and that the group manufactures its own weapons, including hypersonic ballistic missiles. That claim is disputed by U.S. officials who have reported IRGC involvement in directing attacks. Whether or not Tehran is issuing orders on the ground, the strategic alignment is unmistakable. Iran has maintained a persistent chokehold posture in the Strait of Hormuz, and the Houthis are mirroring that approach in the Red Sea. The effect is a pincer that threatens two of the world’s most critical energy transit points simultaneously.

That dual pressure is what makes this escalation harder to contain than previous Houthi actions. A crisis in one strait can be absorbed. A crisis in both reroutes global supply chains and multiplies shipping costs.

What Comes Next

Saudi Arabia faces the same dilemma it faced in 2015. Its objective remains defeating the Houthis or at least pushing them out of Sanaa and restoring the internationally recognized government. But achieving that objective requires ground troops, and Riyadh has shown no appetite to commit them. Airpower alone has not worked before. It is unlikely to work now.

The most probable trajectory is a return to intermittent Saudi bombing campaigns, Houthi absorption of those strikes, and continued ground gains by the rebels. The port city of Mokha is unlikely to be the southern terminus. Johnsen suggested the Houthis will keep pushing south and may target the islands within the Bab el-Mandab itself, including Perim, which would give them direct control of key navigation channels.

For global energy markets, the message is straightforward. The Red Sea is no longer a stable shipping corridor with periodic Houthi disruptions. It is becoming a sustained chokepoint campaign, backed by a rebel force that now controls more of the Yemeni coastline than at any point since the war began. Every kilometer of coast the Houthis hold is another kilometer where a tanker is a potential target.

Until Saudi Arabia decides to pay the ground-troop price it has avoided for a decade – or until the Houthis choose to de-escalate for political leverage – the risk premium on energy shipping through the Red Sea will only increase. The capture of Mokha is a milestone in that trajectory.
