Houthis Seize Mayyun Island, Tightening Bab el-Mandeb Control

Summary

Reports say Houthi forces have seized Mayyun (Perim) Island in the Bab el‑Mandeb Strait, consolidating their control over this key chokepoint. This materially raises near‑term risk premiums for crude, products, and LNG transiting the Red Sea and could further lift already-elevated tanker rates.

Details

  1. What happened: New reporting indicates Houthi forces have seized Mayyun (Perim) Island in the Bab el‑Mandeb Strait, after prior gains along the Red Sea coast including Mokha. Local officials and eyewitnesses state Houthi fighters reached the island after the withdrawal of Saudi‑backed forces. This suggests de facto Houthi control across both shores and the central island that anchors the narrowest section of the strait.

  2. Supply-side impact: Bab el‑Mandeb is the southern gateway to the Red Sea and Suez Canal, with roughly 6–7 mb/d of crude and products plus significant container and some LNG volumes normally transiting. The seizure of Mayyun does not by itself close the strait, but it improves the Houthis’ ability to surveil and potentially target shipping from land with anti‑ship missiles, drones, and mines. That increases the probability and perceived risk of additional attacks or harassment of tankers, especially those linked to U.S., Gulf, or allied interests. Even without a full blockade, higher insurance premia, war‑risk surcharges, speed reductions, and occasional rerouting around the Cape can effectively tighten prompt supply into Europe and the Med and lift delivered costs to Asia.

  3. Affected assets and direction: This development should add to the existing geopolitical risk premium in Brent and WTI, skewing prices higher in the near term, particularly on the front end of the curve and in crack spreads sensitive to Middle East–Europe flows. Clean and dirty tanker freight (VLCC, Suezmax, Aframax) on Red Sea- and Gulf-linked routes are likely to remain bid, reinforcing the record VLCC rate levels already cited in separate reports. European refined products (gasoil/diesel) and fuel oil markets are at risk of further tightness if reroutings or delays materialize. LNG shipping with Red Sea exposure could face higher freight and insurance costs, though the core LNG balance impact is secondary to oil.

  4. Historical precedent: Comparable episodes include the 2023–24 Houthi Red Sea attacks, which pushed up tanker rates and added a several-dollar-per-barrel risk premium to Brent, and earlier closure scares around the Strait of Hormuz. Markets tend to price a persistent but variable premium as long as credible strike capabilities remain in place.

  5. Duration: As long as Houthis hold Mayyun and maintain anti‑ship capabilities, the elevated risk regime in Bab el‑Mandeb is structural rather than transient. Barring a direct military rollback, expect a multi‑quarter to multi‑year impact on routing choices, freight structures, and a sustained geopolitical premium in seaborne Middle East crude and product flows.

AFFECTED ASSETS: Brent Crude, WTI Crude, Gasoil futures (ICE), Fuel oil swaps, VLCC freight (TD3C, etc.), Suezmax and Aframax freight indices, LNG freight rates, Insurance premia for Red Sea and Gulf shipping, Middle East crude official selling prices

VLCC Freight to China Hits Records Amid U.S.–Iran Route Strains

VLCC rates from the Gulf of Oman to China have surged to record highs of about $11.50 per barrel as escalating U.S.–Iran attacks disrupt key Middle East shipping routes. This tightens effective crude supply to Asia via higher delivered costs and increases the risk premium across tanker and oil markets.

Houthi forces have reportedly taken Mayyun (Perim) Island in the Bab al‑Mandab Strait after advancing along Yemen’s Red Sea coast, tightening their grip on one of the world’s key oil and container shipping lanes. For ship crews, insurers, and governments, Red Sea transit is turning from a route choice into a calculated security gamble.

Oil tanker rates hit record highs as U.S.–Iran attacks snarl Middle East routes

The cost of sending a very large crude carrier from the Gulf of Oman to China has jumped to about $11.50 per barrel, a record level, as escalating U.S.–Iran attacks disrupt major Middle East shipping lanes. The spike raises delivered crude prices for Asian buyers and turns maritime security risks into a higher transport bill for the global oil trade.
