Overview of War Leaves U.S. Oil Refiners With Massive Profit Gains

This Wall Street Journal What’s News in Earnings segment explains why U.S. oil refiners are posting exceptionally strong quarterly profits even as consumers complain about high gas prices. The short answer: refiners are benefiting from a much wider crack spread—the gap between crude oil costs and the prices of refined products like diesel, jet fuel, and gasoline. Geopolitical disruptions in the Middle East and Russia have tightened global supply, especially for middle distillates, allowing refiners to sell output at much higher margins.

Key Takeaways

  • Refiner profits surged across the board

    • Marathon Petroleum’s net income jumped more than fivefold to nearly $7.5 billion.
    • Phillips 66, Valero Energy, and ExxonMobil also posted standout refining results.
    • Some refiners reportedly more than doubled earnings versus the already strong 2022–2023 period.

  • The crack spread is driving the results

    • For Valero’s Gulf Coast refineries, analysts at J.P. Morgan estimated the crack spread averaged about $47 per barrel in Q3, up from roughly $30 per barrel the quarter before.
    • That widening margin is the core reason refiners are seeing record operating profits.

  • Diesel and jet fuel are especially important

    • The strongest margins are coming from middle distillates—especially diesel and jet fuel—not just gasoline.
    • These products are currently in shorter supply globally, which boosts refinery profitability.

What’s Behind the Supply Crunch

Geopolitical disruptions

The segment emphasizes that the biggest catalyst is war-related refinery disruption:

  • Middle East / Iran conflict

    • Exxon CEO Darren Woods said roughly one-third of the global shortage is due to the inability to move clean products out of the Middle East.
    • The conflict has crippled refining capacity in the region.

  • Russia and Ukraine war

    • Ukrainian attacks on Russian refineries have significantly reduced output.
    • One estimate cited in the segment suggests about half of Russia’s refining capacity has been taken offline.

Export and capacity shifts

  • U.S. refiners have increased exports by roughly 400,000–500,000 barrels per day since 2025.
  • Middle distillate exports are up by nearly 30% over the last year.
  • Gulf Coast refining capacity is rising, while some West Coast capacity is being shut down.
  • Exxon and Chevron are investing in Gulf Coast projects, which could support future output growth.

Industry Outlook

Near-term

  • Refiners are “running as hard as they can” to meet strong demand and capture favorable margins.
  • The current environment is highly profitable, especially for companies with large Gulf Coast refining systems.

Longer-term

  • The guest, John Auer of Novi Labs, expects the supply picture to improve gradually as:
    • some capacity comes back online,
    • geopolitical conditions potentially stabilize,
    • and more Gulf Coast refining capacity is added.
  • Still, he sees continued growth in Gulf Coast refining through 2040, supported by export markets even if domestic fuel demand declines.

Bottom Line

U.S. refiners are benefiting from an unusually favorable setup: crude prices are up, but refined fuel prices—especially diesel and jet fuel—are rising even faster. That widening gap has created huge profits for refiners, and while the outlook could normalize over time, the industry appears set to remain structurally important to global fuel supply for years to come.
