European diesel refining margin hits record $74.66 as refinery attacks bite

The premium for European low-sulphur gasoil futures over crude, the profit refiners earn turning oil into diesel, hit $74.66 per barrel on Thursday. That is a record. Crude itself sits near $90 a barrel, well below the 2008 high of $147, yet fuel prices keep climbing because the constraint has moved downstream: the problem is no longer just barrels of crude, it is the capacity to refine them.

The squeeze traces to physical outages. Saudi Arabia's Jizan refinery, capacity 400,000 barrels per day (bpd), shut on 27 July following a Houthi attack, taking more than 200,000 bpd of fuel exports offline over three months. Parts of Kuwait's 615,000 bpd Al-Zour plant are down on a power outage. In Russia, Ukrainian drone strikes have forced the Kremlin to ban gasoline and diesel exports, and Lukoil's Perm refinery recently halted a crude distillation unit after a strike. Bloomberg reported that Ukrainian action on Russian export capacity is a primary driver of the diesel move.

What this means for UK buyers

Diesel underpins industrial, agricultural, and logistics costs, so record crack spreads feed through to delivered fuel, distribution surcharges, and any contract with a fuel-linked component. If your renewal carries pass-through logistics or on-site generation costs, model the higher band now rather than assume mean reversion. Reuters noted refining capacity is now viewed as as tight a constraint as crude supply itself.

Watch these markers over the coming weeks:

• European gasoil crack (record $74.66/bbl)
• Eurobob gasoline premium to Brent ($42.21/bbl, near the $44.94 four-year peak)
• European jet fuel margin (above $80/bbl on 29 July)
• US diesel crack spread (record $93.44/bbl)
• Jizan and Al-Zour restart timelines
• Russian export ban duration

The US picture shows the same pattern: the gasoline crack reached $60 a barrel in mid-July, a level last seen in April 2020, on strong exports and firm domestic demand. Valero, the second-largest US refiner by capacity, told investors on Thursday it believes the industry has shifted to a structurally higher mid-cycle margin environment. The Guardian reported that the broader oil complex firmed as attacks near the Strait of Hormuz raised supply fears.

Watch the restart schedules at Jizan and Al-Zour and the shape of Russia's export ban. Both determine how long refined-product tightness persists independent of crude, and whether the current margin spike settles at a new, higher floor rather than easing back.
