Houthi terror attacks on merchant shipping in support of Gaza all but shut down the Suez Canal-Red Sea to global container lines starting in late 2023. Major carriers, which detoured on longer, more expensive voyages around Africa, only recently announced a return of scheduled services to the key shipping lane connecting Asia with the Mediterranean, Europe and North America.
Houthi actions against shipping waned in 2025 as key sponsor Iran was overwhelmed by its own domestic issues.
The Houthi on social media said the maritime embargo was a response to an “unjust and oppressive siege” and that they were ready for “all options,” with further mobilization urged. They also warned that any Saudi “foolish act” would be met with a “comprehensive and decisive” response.
This raises the risk of wider disruption in the Red Sea and nearby shipping lanes, especially because Saudi Arabia is a major energy exporter and maritime traffic through the region is strategically important.
The move also fits a pattern of Houthi threats and retaliatory messaging after recent strikes and escalation.
In practical terms, the political and military threat to Saudi-linked maritime traffic is being seen as an escalation signal aimed at pressuring Riyadh and shaping regional behavior.
