Recent Houthi missile and drone strikes on Saudi airports, including multiple hits on Riyadh’s King Khalid International Airport that killed at least 13 people and wounded hundreds in early October 2026, along with attacks on Aramco facilities, have driven trader focus on the risk of continued cross-border action. These strikes followed Houthi territorial gains along Yemen’s Red Sea coast and a Saudi-backed Yemeni government counteroffensive, prompting tit-for-tat exchanges that include Saudi coalition airstrikes on Houthi positions and infrastructure in Yemen. Traders are monitoring Saudi air defense performance, threats to close airspace, and potential diplomatic or military responses from Riyadh and external actors amid ongoing escalation.
