Houthi Drones Strike Saudi Aramco's Jazan Refinery for Second Time, Threatening August 15 Restart of 400,000-bpd Plant

Yemen's Houthi forces claimed a drone attack on Saudi Aramco's Jazan refinery early Sunday, August 9, striking the 400,000-barrel-per-day complex six days before its scheduled restart. The Saudi Energy Ministry confirmed a fire at the facility, stating that industrial security teams extinguished the blaze with no reported casualties. Saudi Aramco had not issued a separate statement by Sunday morning.

The August 9 strike was the second direct Houthi attack on Jazan in under three weeks. Drones and missiles first hit the complex on July 24, damaging the plant's integrated gasification combined-cycle power unit and tank farm and causing extensive harm to power systems that forced Aramco to suspend all operations by July 27. NASA's Fire Information for Resource Management System detected thermal anomalies across the eastern half of the refinery in satellite imagery within hours. Aramco had targeted August 15 as the restart date, according to analysts cited by LiveNewsChat, with the condition that no further attacks occur during the repair window.

A $21 Billion Complex Representing 4 Percent of Aramco Output

The Jazan complex sits in southwestern Saudi Arabia, close to the Yemeni border, and cost $21 billion to build. It is wholly owned by Saudi Aramco. At full capacity the refinery processes 400,000 barrels of crude daily, representing four percent of Aramco's total oil and liquids production. The facility converts crude into gasoline, ultra-low sulfur diesel, benzene, and paraxylene. Power comes from the world's largest integrated gasification combined-cycle plant, a 3.8-gigawatt unit that converts petroleum coke into hydrogen and fuel gas, per Aramco's own specifications.

That IGCC unit is the same system Houthis damaged on July 24. Without working power generation, the refinery cannot process crude. In its second-quarter and first-half 2026 results, released August 4, Aramco described the company as "maintaining oil deliveries to global markets despite unprecedented regional disruption." The results statement did not name Jazan directly.

$33.4 Million Per Day of Crude Throughput Delayed

Brent crude futures settled at $82.49 per barrel on Friday on ICE. As of early Sunday, August 9, the front-month ICE contract was indicated at $83.55 per barrel, up 1.29 percent from Friday's settle, per TradingEconomics data tracking the ICE benchmark. At that level, each day the Jazan plant remains offline represents roughly $33.4 million of crude going unprocessed. That figure reflects crude value alone; Aramco's refining margin on converted products adds additional economic cost that the company does not separately disclose for Jazan.

Since the July 27 shutdown, the plant was on track to miss processing roughly 7.6 million barrels of crude through its planned August 15 restart, valued at approximately $635 million at Sunday's Brent indication. If the restart slips one week beyond August 15 to August 22, the one-week extension alone would add roughly $234 million of delayed crude throughput. Markets are closed on Sunday. Monday's ICE session will deliver the first traded verdict on the second attack.

Escalating Houthi Campaign Against Saudi Energy Targets

Houthi military spokesperson Yahya Saree described the August 9 drone strike as retaliation for "Saudi drones' breaching Yemen's airspace" over the provinces of Hajjah and Saada along the Yemeni border. The statement followed a pattern of cross-border exchanges that resumed in late July after four years of relative quiet between Houthi and Saudi forces. Three days earlier, on August 6, Houthi missiles struck the Saudi tanker NCC WAFA in the Red Sea, dropping Bab-el-Mandeb vessel traffic by 95 percent and pushing Brent briefly to $82.90, as Oil Authority reported.

Jazan's location, roughly 60 kilometers from the Saada Province border, makes it a persistent target. Houthi strikes on Saudi energy infrastructure carry documented market consequences: the September 2019 attacks on Aramco's Abqaiq processing facility and Khurais oil field temporarily removed roughly five percent of global oil supply and sent Brent surging more than 14 percent in a single session. Brent had traded above $100 per barrel in late July following the first Jazan attack before falling more than 18 percent over two weeks as investors priced in progress on Iran-Oman Hormuz negotiations.

Monday Open Faces Competing Supply and Diplomacy Signals

Crude markets enter Monday with opposing forces at work. Iran-Oman talks on Hormuz shipping routes drove Brent down more than 7 percent for last week by Friday's close. A second Houthi drone on a 400,000-bpd facility six days before a confirmed restart injects new supply uncertainty against that bearish backdrop. Analysts noted the second attack's real significance lies less in additional physical damage than in demonstrating that Houthi forces will re-attack during any repair window, raising the operational risk premium for attempting a restart.

Saudi Aramco's path back to full Jazan output is now uncertain. The Energy Ministry statement gave no guidance on revised restart timing. Repair crews working on the damaged IGCC unit now face additional assessment from Sunday's drone before operations can resume. A second attack on the same infrastructure during the same repair period could extend the outage well beyond any timeline currently available to markets.
