Iran leverages Houthi gains in Yemen to pressure Saudi oil routes and regional rivals

Houthi attacks on Saudi oil infrastructure and the capture of Mokha threaten the Bab al-Mandeb, giving Iran strategic leverage while it balances support for the rebels against broader regional risks.

Houthi forces captured the Yemeni port of Mokha, endangering the Bab al-Mandeb strait that carries Saudi oil shipments, while recent attacks on Riyadh's main airport killed at least 13 people. These moves boost Iran's strategic position, enabling it to pressure Riyadh, raise oil prices and call on the United States to end its Yemen involvement, and Tehran has signaled readiness to mediate between Saudi Arabia and Ansar Allah.

Nevertheless, Iranian and Saudi officials acknowledge that the Houthis pursue independent objectives and are not a simple Iranian proxy, as they have limited attacks to Saudi-linked vessels. Saudi Arabia has turned to China for help, and a maritime coalition of thirteen nations aims to secure navigation through the Red Sea, Bab al-Mandeb and the Gulf of Aden. Experts caution that an emerging regional maritime security framework could curtail Iran's reach over these crucial corridors, intertwining Red Sea security with tensions in the Strait of Hormuz and turning the Yemen conflict into a broader international issue.

Why it matters

The fighting threatens global oil supplies and could reshape power dynamics over vital maritime trade routes.
