"Absolutely Unprecedented": Diesel Crack Spread Hits Record As Refined-Products Crisis Arrives

The report describes a sharp widening in the diesel crack spread, a measure of the margin between diesel and crude, while Brent and WTI remain below $100 a barrel. It attributes the downstream strain to the Russia-Ukraine war, strikes against energy infrastructure and continuing disruptions around the Strait of Hormuz. Governments are also releasing strategic oil reserves, helping suppress headline crude prices even as refined-product markets tighten.

The mechanism runs through refiners, fuel distributors and end users rather than crude producers alone. A shortage of available diesel can lift refining margins and raise costs for transport, agriculture and industrial users, while disruptions to shipping and infrastructure can make regional supply differences more acute.

The key follow-through is whether the diesel crack remains elevated and whether product inventories, refinery utilization and shipping flows deteriorate further. The report does not provide specific crack-spread levels, inventory figures or company guidance, and no company-specific enrichment is available.
