The Houthi Franchise: Why Tehran Cannot Control the Red Sea Crisis

The Houthi movement in Yemen represents a strategic franchise rather than a direct subsidiary of Iran, possessing an independent agenda that could lead to the closure of the Bab el-Mandeb Strait regardless of any diplomatic agreements between Washington and Tehran.

While international attention has focused on the Strait of Hormuz, the Bab el-Mandeb Strait remains a critical point of vulnerability. This maritime chokepoint serves as the vital sea route to the Red Sea and the Suez Canal. Because the Strait of Hormuz is effectively shut, Saudi Arabia is currently routing approximately five million barrels of oil per day through the Red Sea port of Yanbu, placing these shipments within Houthi strike range.

The threat is significant enough that the U.S. Pentagon has altered naval movements. The USS George H.W. Bush carrier strike group, which deployed from Norfolk in late March 2026, is currently rounding the Cape of Good Hope to avoid transiting the Bab el-Mandeb, resulting in a 6,000-mile detour.

Operational Independence and the Proxy Myth

Conventional analysis often describes the Houthis as Iran-backed Yemeni rebels, but this framing suggests a level of command and control that does not exist in practice. Jon Alterman, director of the CSIS Middle East Program, stated in congressional testimony that Iran did not create the Houthi movement and that Iranian support is relatively new and largely opportunistic.

Historical evidence supports this distinction. The Houthis took the capital of Sanaa in September 2014 without significant Iranian support. Meaningful engagement from Iran’s Quds Force—including weapons transfers and technical assistance—did not begin until approximately 2017, after the Houthis had already demonstrated their ability to strike Saudi Arabia independently.

While Iran provides ballistic missiles, cruise missiles, long-range drones, and intelligence, this patronage does not equate to operational command. Recent events in early 2026 illustrate this gap in control:

• In late March 2026, European officials told Bloomberg that Tehran was pushing the Houthis to renew maritime campaigns in the Red Sea. The Houthis declined, choosing instead to launch ballistic missiles at Israel on March 28.
• The March 28 strikes on Israel were a compromise between internal Houthi factions—a cautious camp and a maximalist camp—rather than an order from Tehran.
• Reporting from the Middle East Institute suggests that elements of the Islamic Revolutionary Guard Corps (IRGC) have at times discouraged Houthi escalation to avoid dragging the movement into a suicidal war.

The Internal Structure of the Houthi Movement

The movement is rooted in the Zaydi revivalist study circles of the 1990s in northern Saada province. It is driven by a combination of Yemeni nationalism, Hashemite hereditary entitlement, and an anti-imperial ideology. The group is highly personalized, with real authority resting with Abdul-Malik al-Houthi, who holds the title Alam al-Huda, or Icon of Guidance.

The movement operates a preventive security apparatus modeled on the IRGC, which reports directly to Abdul-Malik al-Houthi. Despite this structure, the group lacks broad domestic popularity. A 2024 poll by the Sanaa Center for Strategic Studies found that only 8 percent of Yemenis in Houthi-controlled areas viewed the movement positively.

Recent military losses have forced Houthi leadership to remain off-grid. Israeli airstrikes in August 2025 killed 12 members of the Houthi cabinet, including Prime Minister Ahmed al-Rahawi. Chief of Staff Mohammed al-Ghamari was killed in October 2025.

Triggers for Escalation

The Houthis have maintained a degree of restraint through early 2026, influenced by the need for self-preservation, a fragile détente with Saudi Arabia, and the lack of domestic support for attacks conducted solely in solidarity with Iran. However, three specific triggers could collapse this restraint:

• U.S. Ground operations against Iran, such as the potential seizure of Kharg Island, which would move the conflict from a rhetorical to an existential struggle.
• Direct strikes on Houthi infrastructure in Sanaa or Hodeidah, which would empower the maximalist camp within the Houthi leadership.
• An existential signal from the Iranian regime. Will Todman of CSIS noted that if Tehran judges the regime is existentially threatened, it will pressure the Houthis to join the conflict.

The economic consequences of a Bab el-Mandeb closure would be severe. Saudi Arabia’s export volumes and Egypt’s balance of payments depend on these routes. If both the Strait of Hormuz and the Bab el-Mandeb close simultaneously, the resulting economic shock would shift from severe to catastrophic for global industrial output.
