Diesel Prices Hold Firm as Refineries Struggle and Crude Finds Its

By: Alex Hodes, Energy Analyst - KC Energy

Crack Spreads, Tariffs, and Tight Diesel: What’s Driving Energy Prices This Summer?

Key Takeaways:

  • Refinery outages and demand surprises are keeping diesel prices firm despite weak crude fundamentals
  • Ongoing tariff negotiations and OPEC quota shifts add complexity to price forecasts
  • U.S. shale growth is flatlining, while global heavy crude supply rises—tightening market balance

On this episode of Focus on Fuels, StoneX Energy Desk Director of Market Strategy Alex Hodes and Energy Risk Manager Trevor McClanahan unpack the hidden forces behind recent market moves—and what they could mean for summer prices.

Refinery Outages Are Supporting Strong Diesel Margins

After a quiet stretch, refined products are back in focus. Despite soft expectations entering 2025, refinery outages across the Atlantic Basin have created a supply crunch. As McClanahan points out, “the diesel market is starved.” That’s reflected in time spreads and crack spreads, with elevated refining margins even as inventories remain tight.

China’s Tariff Reversal Could Lift Demand Expectations

Meanwhile, China’s April crude throughput hit its lowest point in over a year. But as U.S.–China tariff talks progress and some levies have been delayed, Hodes suggests we may be finding an interim bottom: “It’s not bullish, but maybe less bearish.” A bounce in Asia’s imports could be next.

OPEC Strategy: Unity Over Output Discipline

Further into the discussion, the conversation shifts to OPEC, where new quota announcements aren’t necessarily what they seem. “It’s about saving face,” says Hodes. Members like Kazakhstan were overproducing. Rather than enforcing cuts, OPEC raised the quota ceiling to restore unity—without changing real output.

Crude Floors and Shale Slowdown Shape the Summer Outlook

On the U.S. side, shale activity is flattening. “We’re seeing layoffs,” says McClanahan, referencing anecdotal reports from the Permian Basin. Official data supports that trend, showing current production falling short of EIA forecasts.

The big picture? Despite few bullish catalysts, refined product strength and flat U.S. production could lift crude back above its recent $55 floor. “Crack spreads may narrow,” Hodes notes, “but that might be more about crude rising than diesel falling.”

For fuel buyers, traders, and risk managers, that means staying alert to refinery restarts, China’s demand curve, and shifting OPEC headlines. As always, StoneX will be watching—and helping clients prepare.

Perspective: Morning Commentary for August 10

August 10 – The world commodity markets and economy remains at risk amid two wars this morning. Tensions continue to escalate in both the Middle East and the Black Sea – risking pulling other countries into the conflicts. Stocks are down modestly this morning as we start a week of trade in which we’ll see key inflation and retail sales data following a weak jobs report this past Friday. Yet, stocks continue to trade just below record high levels, with the VIX trading near 2026 lows just above 15. The dollar index is trading near 99.7. Yields on 10-year Treasuries are trading near 4.68%, while yields on 2-year Treasuries are trading near 4.23%. The energy and food-based markets are firmer today amid the escalated risks. WTI crude oil is trading near $80, while Brent trades near $85 per barrel. Double-digit gains in the winter wheat markets lead the way for higher grain and oilseed prices.

WTI and Brent Crude Are Now Reading the Strait of Hormuz Differently

WTI and Brent crude are moving to different beats as a possible U.S. Iran deal reshapes the oil market. The two benchmarks are pricing Strait of Hormuz risk in their own ways, and the gap between them says a lot about where crude goes next.

Perspective: Morning Commentary for August 7

August 7 – The U.S. economy unexpectedly lost 23k jobs in July, dramatically below market expectations of an 80k increase and marking the worst Non-Farm Payrolls print since February. Furthermore, May and June were both revised sharply downward, with combined revisions showing 103k fewer jobs than previously reported. Outside of the healthcare sector, which added 22k jobs in July, the losses were very broad-based. Government payrolls saw the largest decline, shedding 53k jobs in July, the largest seen since October 2025, while June was revised down to show a loss of 10k jobs as well. The private sector at least saw growth, adding 30k jobs in July, now matching the month prior after it was revised down from the 49k initially reported, and substantially missing forecasts of 78k jobs being added. This is a sharp reversal in course from the largely better than expected U.S. labor data seen earlier this week.
