Mohammed bin Salman remains Saudi Arabia’s de facto leader as Crown Prince and Prime Minister, with King Salman’s advancing age leaving succession questions focused on whether internal or external pressures could force his removal before or shortly after any formal transition. Recent Houthi advances along Yemen’s Red Sea coast, strikes on Saudi oil infrastructure, and disruptions from Iran-related conflicts have exposed limits to Riyadh’s military reach and Vision 2030 diversification plans, prompting MBS to seek stronger U.S. security guarantees during an expected Washington visit for a mutual-defense pact, F-35 acquisitions, and nuclear cooperation. Experts note his decade-long consolidation of security and economic institutions makes a sudden ouster unlikely absent major military setbacks or economic contraction, though scheduled diplomatic engagements and regional escalation risks remain key variables for traders assessing removal timelines.
