Diesel Crack Spread Hits Record $102 as Global Refinery Crisis Deepens
The US diesel crack spread hit a record $102.20 a barrel Monday, more than five times its normal range, as a convergence of war, drone strikes, and refinery outages squeezes global fuel supply.
Before this year, the spread had never exceeded $89 a barrel, with the prior record set in October 2022. The gauge measures the premium refiners earn turning crude into diesel, and it settled in triple digits for the first time ever.
The refining bottleneck
Brent crude sits around $91 a barrel, cushioned by strategic reserve releases. The US-Iran war effectively closed the Strait of Hormuz in late February, and Persian Gulf diesel exports have fallen 80% year over year, nearly double the 48% decline in crude exports from the region.
Russia, traditionally one of the world's largest refined-fuel exporters, banned diesel exports after Ukrainian drone strikes damaged its refineries. That left major buyers like Brazil and Turkey scrambling for replacement cargoes.
Separate strikes on refineries in Iran, Saudi Arabia's Jazan facility, and Libya knocked out additional processing capacity worldwide.
US refiners stepped in, sending distillate exports to a record 1.9M barrels a day in the first week of August. But that is draining domestic inventories to their lowest level for this time of year since 1996.
The Strategic Petroleum Reserve has already fallen below 300M barrels from earlier crude releases, and that crude does nothing for a diesel shortfall, since the SPR holds crude, not refined product.
Diesel's resistance to demand destruction makes the squeeze particularly stubborn. Trucking companies can't quickly replace fleets, and farmers can't stop running equipment during harvest season, which is starting now.
"Diesel markets appear poised to stay tight, volatile, and expensive well into next year."

Refiners converting the crisis into cash
Valero Energy and Marathon Petroleum are the direct beneficiaries. Valero's realized refining margin roughly doubled year over year in Q2, reaching $23.62 a barrel. Marathon's jumped from $17.58 to $36.33 a barrel.
Marathon posted $5.1B in Q2 net income and returned more than $2.8B to shareholders through buybacks and dividends, finishing the quarter with $7.8B in cash.
Valero posted $3.7B in net income and returned $2.6B (a 59% payout ratio) while holding net debt-to-capitalization at just 11%. Phillips 66 earned $3.85B in Q2, with refining margins more than doubling from Q1.
The windfall has a ceiling. Crack spreads this extreme historically compress once refiners ramp utilization or a geopolitical resolution reopens Hormuz flows. Investors chasing today's spread as a permanent trade are ignoring the cyclicality that has defined refining for decades.
