How cascading crises are testing Saudi Arabia’s foundations

In September 2026, Saudi Arabia faced a cascade of military, economic, and diplomatic challenges under Crown Prince Mohammed bin Salman (MBS). Originating from conflicts in Yemen, these setbacks threatened the kingdom's foundations. The Houthis, with Saudi backing, seized control of Yemen's Red Sea coastline, including crucial ports and key strategic locations.

This move limited Saudi-linked shipping routes through the Bab al-Mandeb Strait, a narrow waterway just 12 miles wide, and disrupted oil exports. These disruptions threatened to cripple Saudi Arabia's economy, which heavily relies on oil revenues and the diversification efforts outlined in Vision 2030.

The crisis also strained diplomatic relations as Saudi Arabia sought assistance from unlikely allies, including Israel, despite the latter's sensitive geopolitical standing in the Muslim world. The kingdom's traditional allies, such as Turkey and Pakistan, failed to provide the promised military support, leaving Saudi Arabia in a precarious position.

Internally, the regime's heavy-handed suppression of dissent and powerful security apparatus faced growing internal dissent, particularly among the youth and women advocating for social reforms. The kingdom's economic and political vulnerabilities, coupled with the external pressures, highlighted the fragile nature of MBS's rule.

As the crisis unfolded, it underscored how rapidly developing events in the region could threaten the stability and legitimacy of authoritarian systems.
