Houthi Strike on Saudi Aramco’s Jazan Refinery: Goldman Sachs Says Diesel Is at the ‘Epicenter’ of a Historic Supply Squeeze

Jazan is a particularly diesel-rich complex, so its shutdown disproportionately hits middle-distillate supply and has been described as signaling "the next fuel shock" for diesel prices .

Goldman Sachs’ Assessment of the Broader Fuel Squeeze

Goldman Sachs published its updated view on July 30, 2026, calling diesel "at the epicenter" of a historic supply squeeze . The bank's key findings:

• Global refining activity fell in July to its lowest seasonal level since the pandemic, driven by war-induced outages in Russia and the Middle East, along with weak refinery runs in other regions . Middle East conflict and Strait of Hormuz shipping disruptions have hit refined product markets far harder than crude oil markets .
• Refined product margins are running 2–3 times higher than the 2013–2019 average, with diesel margins projected to exceed pre-war estimates by $19 to $26 per barrel .
• U.S. diesel inventories are on track for an August crunch, with stocks at their lowest since 2003 . The international refined product export collapse is compounding the shortage .

The bank noted that war-induced outages in Russia and the Middle East, combined with subdued Chinese processing, have cut global throughput by an estimated 6.5 million barrels per day from a year earlier . Increased output in the Americas and Africa has offset only about one-third of the lost supply .

How the Jazan Outage Worsens an Already Critical Situation

The Jazan shutdown is not the root cause of the diesel crisis; rather, it is a fresh supply-side shock layered on top of an already depleted system. Before the attack, Goldman Sachs had already forecast that refined product margins would remain two to three times higher than the 2013–2019 average through the remainder of 2026, with diesel margins specifically $19 to $26 above pre-war levels . The bank had also warned of an August U.S. diesel crunch as inventories sat at their lowest since 2003 .

The timing is critical. The Jazan outage directly overlaps with the tightest projected period of the summer driving and agricultural season, when diesel demand for farming and trucking peaks in the Northern Hemisphere. The attack has materially worsened the supply-demand balance at the most acute moment, reinforcing Goldman's call that diesel markets face the biggest supply squeeze in the oil complex .

Outlook Through Mid-August and Beyond

With Jazan expected offline until roughly August 15, the immediate outlook is highly sensitive to repair timelines. Any extension beyond that date would remove an additional 400,000 bpd of mostly diesel output from a market that can ill afford it.

Goldman Sachs sees elevated refined fuel margins persisting through the remainder of 2026 . The structural tightness is underpinned by a global refining capacity shortfall, accelerated European refinery closures, China's declining diesel output, and constrained heavy crude supply — factors that predate the Jazan attack and will outlast it .

The Jazan shutdown does not create the squeeze from scratch, but it materially worsens the supply-demand balance at the most acute moment, reinforcing Goldman's call that diesel markets face the biggest supply squeeze in the oil complex .
