In a major escalation amid the ongoing Middle East conflict involving Iran, Saudi Arabia has temporarily halted oil loadings at the Port of Yanbu on the Red Sea coast, two sources told Reuters. This decision follows recent Iranian aerial strikes targeting key energy infrastructure, including the SAMREF refinery—a joint venture between Saudi Aramco and ExxonMobil—located in the port area.

The development, reported widely on March 19, 2026, has sparked immediate concerns over global oil supply stability, especially as the Strait of Hormuz remains effectively closed due to regional tensions.

Why Yanbu Matters in the Current Crisis

The Port of Yanbu serves as a critical alternative export route for Saudi crude oil, bypassing the Strait of Hormuz—the narrow chokepoint through which roughly 20% of the world’s oil typically flows. With Iranian actions disrupting Hormuz traffic, Saudi Arabia ramped up shipments via its East-West pipeline to Yanbu, pushing exports to record levels approaching 3.8-4 million barrels per day (bpd) in recent weeks.

This Red Sea outlet became the primary (and in some reports, the only viable) export path for Gulf Arab crude after the Hormuz shutdown. Facilities like the SAMREF refinery (capacity around 400,000 bpd) play a key role in processing and loading operations.

However, Iran’s Islamic Revolutionary Guard Corps (IRGC) issued evacuation warnings to multiple Gulf energy sites, explicitly naming SAMREF in Yanbu as a target in retaliation for prior strikes on Iranian facilities (including the South Pars gas field).
