Chatham House: Iran War Reshaping Saudi Arabia's Strategic Geography Toward Red Sea

Chatham House published a major policy analysis on May 27 detailing how the Iran war and Hormuz closure (since February 28) are forcing Saudi Arabia to permanently reassess its energy export architecture and strategic geography. The analysis identified three transformative pressures: (1) The Strait of Hormuz closure has permanently demonstrated Saudi Arabia's vulnerability to its eastern route — accelerating PIF and Aramco investment in Red Sea infrastructure and the East-West Pipeline as a long-term strategic imperative, not an emergency workaround. (2) The UAE's exit from OPEC+ (effective May 1) — driven by Abu Dhabi's desire for higher production quotas and frustration with Saudi-led restraint — has significantly weakened the cartel's cohesion and MBS's ability to use OPEC+ as a geopolitical instrument. Saudi Arabia now faces managing OPEC production dynamics without its largest Gulf partner. (3) Growing Houthi threats to the Bab el-Mandeb Strait — the southern Red Sea chokepoint — represent a new constraint on Saudi Arabia's westward export reorientation. Chatham House concluded that Saudi Arabia's 'Red Sea pivot' creates new dependencies even as it escapes the Hormuz dependency.
