**Deck**: A closer relationship between Yemen’s Houthi movement and Somalia’s al Shabaab is increasing security risks in the Gulf of Aden, a corridor that carried about 12% of global seaborne oil trade before the current war with Iran.

An increasingly close relationship between Yemen’s Houthi movement and Somalia’s al Shabaab is adding a new layer of risk to one of the world’s key maritime oil routes, the Gulf of Aden.

According to research cited in recent reporting, the alliance between the Houthis and al Shabaab is tightening. Both groups already pose threats in their respective areas: the Houthis in Yemen and al Shabaab, an Al Qaeda‑linked organisation, in Somalia.

The Gulf of Aden, which lies between Yemen on the Arabian Peninsula and the Horn of Africa, carried about 12% of the world’s seaborne oil trade before the onset of the current war with Iran. That made it a critical corridor for tankers moving crude and refined products between the Middle East and global markets.

Closer cooperation between armed groups on both shores heightens the danger that commercial vessels could face a broader set of hostile actors as they pass through the region. The presence of an Iran‑backed movement in Yemen and an Al Qaeda affiliate in Somalia along the same waterway complicates efforts to secure shipping lanes.

For shipowners, crews and insurers, this emerging alignment means that a route already associated with piracy and conflict now carries an additional strategic risk. Any perception that more coordinated activity is possible can increase security costs and may influence decisions on whether to reroute vessels.

Regional governments and international partners monitoring the Gulf of Aden will be watching for concrete signs of operational cooperation between the two groups, such as shared tactics or support networks, which would mark a further escalation in the threat to maritime traffic.

Key indicators in the months ahead include changes in reported incidents against shipping in the area, any confirmed links between Houthi and al Shabaab activities, and adjustments to naval patrols or insurance terms that reflect a reassessment of the security environment in the Gulf of Aden.
