Houthi strikes on Saudi refineries push Brent past $100 on three-front crisis

Saudi Arabia's oil export corridor is under simultaneous attack from both ends, trapping the kingdom between two blocked chokepoints.

Yemen's Houthi movement struck Saudi Aramco's Jizan refinery and the Yanbu export terminal Saturday, setting the Jizan complex ablaze and pushing Brent crude above $100 a barrel as three global maritime chokepoints simultaneously tightened.

"The pipeline bypassed one chokepoint only to deliver Saudi crude to another controlled by the same adversary coalition," said Helima Croft, head of commodity strategy at RBC Capital Markets. "There is no third corridor."

The Jizan refinery — processing 400,000 barrels a day — burned after what NASA's FIRMS satellite system confirmed as multiple thermal anomalies at 01:17 UTC. At Yanbu, Greek-operated air defenses intercepted two ballistic missiles, Saudi Civil Defense said. The attacks followed five days of escalation: the Houthis declared a naval blockade on July 20, struck two Saudi tankers on July 22-23, and vowed retaliation after the Saudi-led coalition bombed Hodeidah on July 24.

The strategic architecture is the story. Saudi Arabia pushed its East-West Pipeline to a record 7 million barrels a day in March after Iran closed the Strait of Hormuz, rerouting crude to Yanbu on the Red Sea. But every tanker leaving Yanbu must pass through the Bab al-Mandeb — now inside a Houthi-declared blockade zone. Yanbu handled 92% of Saudi seaborne crude exports in June, Kpler data show. A sustained disruption there, combined with the Hormuz closure and Ukrainian drone strikes halting loadings at Russia's Novorossiysk terminal, threatens roughly a quarter of global oil and gas supply.

How the Pipeline Became a Trap

The Petroline runs 1,201 kilometers from the Abqaiq processing complex to Yanbu, built in the 1980s as insurance against a Hormuz closure. For four decades it sat largely dormant. In 2026 it became Saudi Arabia's only functioning export route — and the Houthis' primary target. The group's shore-based anti-ship ballistic missiles carry approximately 400 kilometers of range, sufficient to cover the full width of the Bab al-Mandeb. Their targeting intelligence exploits the Automatic Identification System, a maritime tracking protocol that broadcasts each vessel's position and destination, cross-referenced with Saudi port call records.

The Houthis' ability to reach Yanbu's departing tankers without deploying a single vessel has transformed the Red Sea into a contested waterway. The EU's Aspides naval force has advised vessels to minimize AIS transmissions, though disabling the system eliminates its maritime safety benefits. Saudi air defense intercepted two missiles Saturday but has not demonstrated capacity to neutralize the full salvo architecture of a dual-target operation.

Oil Markets and the US Consumer

Brent crude had already risen approximately $28 a barrel over three weeks before Saturday's strikes, according to UBS strategist Giovanni Staunovo. The July 23 close at $100.69 was the highest since May, and Goldman Sachs projected Brent above $120 by the fourth quarter if Hormuz disruptions alone persisted. Saturday's refinery attacks put that ceiling in a different context: markets are pricing a potential systemic failure of Middle Eastern oil export logistics.

At the retail level, the $4.09-per-gallon national average recorded by AAA on July 23 reflected only the tanker-strike wave. Each sustained $10-per-barrel increase in Brent translates to approximately 24 cents per gallon at the pump. US crude inventories have fallen to their lowest level since the Reagan administration, while OECD government-controlled stocks dropped to the lowest since December 1990, limiting the buffer for any further disruption.

What Comes Next

Saudi Arabia's available options narrow to costly ones: funneling crude north through the Suez Canal and SUMED pipeline route at greater cost and slower pace, or accepting reduced export volumes. Very large crude carriers face draft limitations in the Suez Canal, forcing downgrades to smaller vessels and adding freight costs. The Cape of Good Hope route adds two to three weeks per voyage.

A combined Hormuz and Bab al-Mandeb closure at full effect would block access to approximately 25% of global oil and gas supply, based on 2024 throughput data from both straits. The Caspian Pipeline Consortium's Black Sea terminal near Novorossiysk remains suspended after Ukrainian drone strikes, compounding the supply crisis from a third direction. Russia's diesel exports have fallen to roughly half their year-ago level after sustained attacks on refineries, and the country banned diesel exports through July.

The Houthi political bureau member Hizam al-Assad warned on X that "the next steps could involve shutting off the tap altogether." Saudi Arabia's coalition vowed an uncompromising response. With both sides framing the coming phase as uncapped escalation, the structural dilemma remains: the pipeline relocated the chokepoint from one arm of the adversary coalition to the other, and there is no third corridor.
