Saudi Aramco shuts Jizan refinery after Houthi strike

On July 28, 2026, Saudi Aramco shut down its 400,000-barrel-per-day refinery in Jizan after a Houthi attack, according to an IIR note. The strike also contributed to a multi-month low in Red Sea tanker traffic as the Houthi threat persists. However, some reports indicate that Red Sea tanker traffic has risen due to progress in US-Iran talks, which has buoyed shippers. The shutdown underscores ongoing regional tensions affecting oil infrastructure and maritime routes.
