Houthi–al-Shabaab Alliance Threatens to Turn the Gulf of Aden into a New Oil Chokepoint
A growing partnership between Yemen’s Houthi movement and Somalia’s al-Shabaab is emerging as a new threat to the Gulf of Aden, a corridor that once carried 12% of global seaborne oil. The alignment of a regional militant group and an al-Qaeda affiliate could turn an already volatile coastline into a far more dangerous route for tankers and crews.
An increasingly close alliance between Yemen’s Houthi movement and Somalia’s al‑Qaeda affiliate al‑Shabaab is creating a fresh layer of risk for one of the world’s most important energy corridors. According to a detailed investigation described in recent reporting, cooperation between the two groups now threatens to destabilise the Gulf of Aden, through which roughly 12% of the oil transported by sea passed before the current war with Iran drastically altered shipping patterns.
The Houthis, who control large swathes of northern and western Yemen, have already demonstrated their ability to target commercial shipping with missiles and drones in the Red Sea and adjacent waters, forcing major reroutings and higher costs for global trade. Al‑Shabaab has for years carried out deadly attacks inside Somalia and against regional targets, while exploiting weak coastal governance. A deeper partnership between them would combine the Houthis’ strike capabilities and geographic position astride key sea lanes with al‑Shabaab’s networks and sanctuary on the African side of the Gulf.
For tanker crews and shipping companies, the prospect is stark. The Gulf of Aden links the Red Sea and Suez Canal to the wider Indian Ocean; any expansion of hostile activity across both its northern and southern shores would reduce the room for safe navigation even further. Crews already face extended voyages and heightened anxiety due to missile, drone and piracy threats. An operational alliance between armed actors on both sides of the waterway would make the Gulf feel less like an open corridor and more like a stretch of sea bracketed by hostile coasts.
Energy importers in Europe and Asia would pay the price through higher transport costs and greater vulnerability to supply interruptions. Even when no ship is actually hit, the perception of risk pushes up insurance premiums, encourages ships to take longer routes around southern Africa, and can prompt governments or companies to delay cargoes. In tight markets, a few days’ hesitation in moving oil or refined products can translate into price spikes that filter down to consumers in the form of higher fuel and heating bills.
Strategically, a Houthi–al‑Shabaab axis would represent a troubling convergence between a regional actor aligned with Iran and a long‑standing jihadist organisation with its own agenda. While their ideologies and patrons differ, shared interests in raising the cost of Western and allied presence in the region, extorting shipping, or pressuring rival governments could give them enough common cause at sea. That, in turn, would complicate the task of naval coalitions already stretched by patrols from the Red Sea to the Arabian Sea.
For littoral states such as Yemen, Somalia and Djibouti, the deepening of such ties would make it harder to stabilise their own territories and waters. Revenue from smuggling, protection rackets or covert support could strengthen armed groups at the expense of fragile central authorities. Ports that might otherwise serve as hubs for regional trade risk being overshadowed by the image of a coastline where the rules are set by militias and extremists rather than customs officials and harbour masters.
The insight for policymakers is that chokepoint risk does not require a formal blockade or a single dominant actor; it only takes enough disruptive capability on both banks of a narrow sea to make shipowners and insurers hesitate.
Naval planners and energy security officials will now watch closely for evidence of joint operations, shared weapons flows or coordinated messaging between the Houthis and al‑Shabaab. Changes in attack patterns in the Gulf of Aden, new advisories from maritime security centres, and any moves by major navies to adjust their patrols or convoy arrangements will be key indicators of whether this emerging alliance is becoming a practical threat to global shipping — or remains, for now, a dangerous possibility taking shape along two troubled coasts.
