Mohammed bin Salman’s position as Saudi Arabia’s de facto leader has been reinforced by his recent formal appointment as prime minister in a royal decree from King Salman, continuing the gradual transfer of executive authority while the monarch retains head-of-state status. King Salman, aged 86 and recently treated for a lung infection, has overseen cabinet continuity, with MBS’s brother Khalid assuming the defense portfolio. Persistent Houthi missile and drone strikes on Riyadh infrastructure since early October have disrupted major investment forums and highlighted regional security strains tied to Yemen and Iran-related tensions under the current U.S. administration. Economic pressures, including scaled-back Vision 2030 projects and a projected GDP contraction, add domestic strain, though reporting indicates no organized internal challenge to MBS’s centralized control over key ministries, security, and economic decisions. Scheduled cabinet sessions and regional summits remain the nearest potential catalysts.
