Houthi Missiles Strike Saudi Tanker NCC WAFA, Bab-el-Mandeb Traffic Drops 95% and Brent Hits $82.90

Brent crude settled at $82.90 per barrel on Thursday, up 4.34% from the prior close, after Houthi forces claimed ballistic missile strikes on the Saudi products tanker NCC WAFA near the Yambu area of the northern Red Sea. WTI crude closed at $77.69 per barrel, a gain of 3.28% on the session, according to OilPrice.com market data. Together, the two benchmark moves reflected broad market concern over acute physical supply disruption at both the Strait of Hormuz and the Bab-el-Mandeb.

Shipping Traffic Collapses at Two Critical Chokepoints

Vessel tracking data showed traffic at the Bab-el-Mandeb Strait dropping from 20 transiting ships on Tuesday to a single vessel by Wednesday. That is a 95% single-day collapse in throughput at the strait connecting the Red Sea to the Gulf of Aden and a principal gateway for crude bound for Europe and Asia. At the Strait of Hormuz, two vessels transited Wednesday compared to eight on Tuesday, a 75% decline in a single 24-hour period.

The NCC WAFA, a Saudi-flagged products tanker, had last broadcast its position on July 19 while traveling southbound through the Red Sea. Houthi forces in Yemen announced a formal blockade of Saudi maritime traffic on July 22. Wednesday's missile claim marked the first direct tanker strike reported since that blockade declaration.

A $3.45 Per Barrel Premium Above the Diplomatic Settlement

An earlier Oil Authority report tracked Brent settling at $79.45 when markets priced in partial relief from Iran-Oman negotiations over Strait of Hormuz management. Thursday's close at $82.90 places Brent $3.45 per barrel above that diplomatic-relief settlement, implying a renewed physical supply premium that diplomatic progress alone has not resolved. The prior report noted EIA had confirmed a 2.5 million barrel US crude build during the same period, data that pointed toward demand softness. Physical supply disruption is now overriding that bearish inventory signal.

Security firms monitoring the area described current conditions as "the worst safety situation since the Iran war began." Iran-aligned Houthi forces have conducted attacks on commercial vessels throughout 2025 and into 2026, escalating from intermittent incidents to a declared blockade of Saudi-flagged shipping in the Bab-el-Mandeb corridor. Wednesday's missile claim against NCC WAFA suggests the blockade has moved from declaration to active enforcement.

Physical Supply Risk at Both Straits

The Bab-el-Mandeb is one of seven global oil transit chokepoints identified by the U.S. Energy Information Administration as critical to global petroleum markets. A sustained 95% reduction in vessel transits at Bab-el-Mandeb would force crude and product carriers to reroute around the Cape of Good Hope, adding approximately 10 to 14 days of sailing time and significantly higher freight costs per voyage. European and North American importers dependent on Middle Eastern crude blends would face the highest additional freight costs from that rerouting.

Saudi Aramco separately deepened discounts on crude sold to Asian buyers this week, a response to demand competition from Russian ESPO blend and other discounted alternatives, according to OilPrice.com reporting published Thursday. Saudi Arabia now faces the dual pressure of tanker attacks on its shipping and price competition in its largest export markets. Higher tanker insurance premiums from the Red Sea conflict compound the margin pressure for Saudi crude exporters.

OPEC+ Production Policy Context

WTI at $77.69 per barrel places the North American benchmark at a level that has historically prompted OPEC+ discussions about the pace of additional supply additions. Brent above $80 has historically been a reference threshold cited in Saudi production strategy discussions. If Thursday's settlement holds through the week, OPEC+ members may revisit planned September and October supply returns at their next monitoring meeting.
