Houthi forces in Yemen have announced an immediate maritime embargo against Saudi Arabia, creating a direct threat to Saudi-linked shipping in the Red Sea and amplifying risk for vessels loading at Yanbu.

We understand that Houthi forces in Yemen have announced a maritime embargo against Saudi Arabia, effective immediately. According to a statement from a Houthi spokesman, the measure is a response to a recent Saudi attack and a long term blockade imposed on Yemen. While the Houthi statement did not provide specific details on how the embargo will be enforced, it significantly elevates the threat level in the southern Red Sea.

The announcement follows previous Houthi threats to close the Bab el Mandeb Strait and a demonstrated capability to target international shipping, seen in the campaign of attacks beginning in late 2023 which caused widespread vessel diversions.

Impact on cover or operations. 

The announcement presents a direct and material threat to any vessel with a perceived link to Saudi Arabia transiting the Red Sea.  The risk is particularly acute for tanker traffic. According to open sources, ongoing disruption in the Strait of Hormuz has led Saudi Arabia to divert a significant and growing volume of its crude oil exports to its Red Sea port of Yanbu.  Data from the first half of July 2026 reportedly shows that pipeline volumes to the Red Sea for export have quadrupled since the start of wider regional conflict, with approximately 75% of Saudi crude and condensate exports being shipped from Yanbu.

Vessels, including VLCCs, loading at Yanbu must transit south through the Bab el Mandeb Strait, placing them directly within the area where Houthi forces have previously conducted successful attacks. In the Club’s view, the lack of specificity in the embargo announcement means that a wide interpretation of ‘Saudi-linked’ is the most prudent approach. This could be deemed to include not only vessels flagged, owned, or managed by Saudi interests, but also those carrying Saudi cargo, chartered by Saudi entities, or even having recently called at a Saudi port.

This development adds to the existing high risk environment. Members should be aware that transiting the southern Red Sea with any Saudi nexus may have significant implications for War Risks cover. All voyages in the region require a careful assessment of risk.

Recommended Action

The Club strongly advises Members to exercise extreme caution. Any vessel with a potential Saudi nexus intending to transit the southern Red Sea or call at Yanbu should have its voyage risk assessment urgently reviewed.  Members should conduct enhanced due diligence to determine if any aspect of their vessel, voyage, cargo, or commercial relationships could be construed as having a link to Saudi Arabia.  Given the ambiguity of the threat, we recommend that Members considering voyages that may be affected contact the Club to discuss the specific circumstances of the voyage, review the adequacy of their insurance cover, and consider potential mitigation strategies.
