Houthi Blockade of the Bab al-Mandeb Spurs Rerouting, Higher Costs and New Shipping Fronts

Core Event
On July 22 2026 the Iran-aligned Houthi militia announced a naval blockade of Saudi-linked ports in the Bab al-Mandeb Strait. Within days ship-tracking data showed five tankers altering course, with two heading for the Suez Canal instead of Yanbu. The move coincided with a renewed U.S.–Iran air campaign that left the Strait of Hormuz largely shut, prompting Saudi Arabia to divert oil exports through the Red Sea pipeline to Yanbu.
Background & Context
The Houthis, who control Yemen’s capital Sanaa and the Red Sea port of Hodeida, have acted as an Iranian proxy since 2023, targeting vessels they deem supportive of Israel’s war in Gaza. In July 2026 they warned ships heading to Saudi ports of “open targets” for missiles and drones. The blockade follows recent Iranian attacks on commercial shipping in Hormuz, a chokepoint that carries about one-fifth of global oil.
Data & Statistics
- Five tankers changed course on July 22; a sixth vessel (the carrier Liu Jiang Kou) turned away in the Gulf of Aden.
- Three Saudi-crude tankers, including the Xin Long Yang, made U-turns on July 23, opting for the Suez route.
- Crossings through Bab al-Mandeb fell 30 % on July 23, from 41 vessels the previous day to 29.
- Insurance premiums for Red Sea transits rose to ? 1 % of hull value, versus 0.1 % for western Saudi waters.
- Only one tanker crossed the Strait of Hormuz on a Thursday, the lowest level since May 7.
Why It Matters
Rerouting oil-laden tankers around the Suez adds roughly 10,000 nautical miles and 34 days of sailing, inflating freight costs by more than $5 million per voyage and raising Suez fees by about $1 million. Higher war-risk insurance and longer journeys push end-user fuel prices, contributing to Brent crude trading above $100 per barrel in July 2026.
Official Statements & Responses
- U.S. Secretary of State Marco Rubio warned that allowing a nation to control an international waterway “sets a dangerous precedent.”
- President Donald Trump pledged “major military punishment” for further Houthi attacks and said the U.S. would hold Iran responsible.
- The Saudi Press Agency confirmed the tanker Encelia was struck, igniting a fire but leaving the crew unharmed.
- The UK Maritime Trade Operations centre reported an “unknown projectile” hitting a tanker near al-Shuqaiq.
Criticism & Opposition
Maritime analysts warned of broader market impacts. “After the collapse of the MOU, we have entered the worst phase of this conflict for merchant shipping,” said Dimitris Maniatis, CEO of Marisks. He added that Iran’s desire to assert authority in Hormuz is the primary driver of the shutdown.
Conflicting Reports & Gaps
- Tracking data showed roughly 15 ships transiting Hormuz on a recent Thursday, a 50 % drop from pre-conflict averages, while other sources reported only one successful crossing that day.
- Insurance cost estimates vary: some market reports cite a rise to 7.5–10 % of hull value for Bab al-Mandeb, whereas others note a more modest increase to 1 % for Red Sea voyages.
What’s Next
- The EU’s Aspides naval force has advised vessels to minimize AIS transmissions while the blockade persists.
- Negotiations to revive the June 17 MOU on Hormuz reopening remain stalled, with mediators in Pakistan and the UAE seeking a new framework.
The unfolding blockade shows how simultaneous threats to Bab al-Mandeb and Hormuz can reshape global energy logistics, elevate shipping costs, and heighten geopolitical risk for maritime commerce.
