Saudi Arabia faces mounting pressure amid escalating conflict in Yemen that threatens to undermine the kingdom’s regional influence and internal ambitions. The recent seizure of the Bab al-Mandeb strait by Houthi forces marks a significant shift in the seven-year-old war, raising concerns over control of a critical maritime chokepoint through which a substantial portion of the world’s oil shipments pass.

The conflict’s urgency intensified in 2022 following a Houthi attack on an oil facility in Jeddah, which sent thick plumes of smoke over the coastal city just as it was preparing to host the Formula 1 Grand Prix. The assault underscored the incompatibility between ongoing warfare and Saudi Arabia’s broader goals of economic diversification and tourism development under Crown Prince Mohammed bin Salman. Shortly after the incident, Saudi Arabia and the Houthis agreed to a truce, temporarily halting hostilities that had already claimed hundreds of thousands of lives and failed to dislodge Houthi control of Yemen’s capital, Sanaa.

However, the ceasefire has shown signs of unraveling in recent months. In July, the Houthis accused Saudi Arabia of imposing a blockade on Yemen after the Saudi air force targeted a runway in Sanaa to prevent an Iranian aircraft from landing. This action was followed by Houthi attacks on Saudi oil tankers, aligning with Iran’s broader strategy of restricting oil flows through the Strait of Hormuz. The conflict has further widened as Houthi allies in Iraq bombed a pipeline that redirects oil from the Persian Gulf to the Red Sea, threatening to disrupt more than 4 percent of global oil supply.

Saudi Arabia now confronts two difficult strategic options. One path involves intensifying military operations against the Houthis, despite limited success so far. Saudi-led airstrikes have been met with continued Houthi missile attacks, including a recent barrage targeting southern Saudi cities that wounded at least 13 people. Yet, a renewed military campaign carries significant risks. Riyadh’s calls for increased support from the United States have been largely unheeded, and key regional allies, such as Pakistan, have expressed reluctance to engage in the conflict. The kingdom’s former partner in Yemen, the United Arab Emirates, withdrew earlier this year after internal divisions and a mutiny challenged the Saudi-backed government’s hold on power.

Alternatively, Saudi Arabia could seek a diplomatic resolution that concedes Houthi control over the Bab al-Mandeb strait and diminishes Riyadh’s strategic dominance in the region. While this would reduce the immediate military and economic burdens of war, it represents a major concession for a kingdom that views itself as a leading regional and Islamic power. The prospect of relinquishing control over such a vital waterway is considered by many within Saudi leadership as a humiliating setback.

The conflict’s trajectory poses significant implications for Saudi Arabia’s domestic and international ambitions. The kingdom’s economy has already suffered disruptions linked to regional tensions between the United States and Iran, which have constrained oil exports. As Riyadh prepares to host the 2030 World Expo and follows up with the 2027 FIFA World Cup, prolonged instability in Yemen threatens to overshadow these high-profile events and stall the Crown Prince’s vision for transformation.
