The Houthi blockade against Saudi Arabia has produced its first confirmed vessel casualty. The Saudi-flagged tanker Encelia was struck by a projectile near Bab el-Mandeb on July 22 and caught fire; the crew is fighting the blaze and is reported safe. The UK Maritime Trade Operations authority independently confirmed a tanker "struck by an unknown projectile" in the area, and the Saudi Press Agency confirmed the Encelia was hit. The Houthis also claim a strike on a second Saudi tanker, the Layla, not yet independently confirmed. Houthi spokesman Yahya Saree declared Bab el-Mandeb "fully closed" to Saudi-flagged tankers going forward and said the strikes have already forced ~10 vessels to turn back rather than risk the transit.

The strike resolves the open question hanging over this blockade since it began July 20: whether charterers were rerouting on rhetoric alone or a real threat. It also lands three days after Saudi Arabia's first public threat of "force" against the blockade, a threat Riyadh has not yet acted on.

At stake is the East-West Pipeline to Yanbu, Saudi Arabia's ~2.5M bbl/day bypass route around the closed Strait of Hormuz. Asia-bound cargo loaded there has no way around Bab el-Mandeb short of the Cape of Good Hope, a 10-12 day, ~6,000nm detour. War-risk hull premiums at the strait stood at 0.75% of vessel value ahead of this strike; expect the next quoted rate to move materially higher now that the threat has a confirmed casualty attached.

Watch for a Saudi military response, further premium repricing, and whether the diversion pattern accelerates beyond the vessels already named.
