US Diesel Prices Hit Record High as Global Refining Capacity Crumbles
TREE NEWS reports: US retail diesel prices surged past $6.45 per gallon this week, a historic high, as simultaneous wars in Ukraine and the Middle East cripple the global refining system. The crisis has triggered fuel shortages from rural Brazil to Libya and parts of Africa, threatening the industrial, transport, and agricultural sectors that depend on diesel. In Washington, political pressure is mounting to ban exports in a bid to cool domestic prices, with Representative Tim Burchett introducing a diesel export ban bill and Senate Majority Leader John Thune expressing openness to the idea.
How the World Lost Its Diesel Supply
Over the past decade, Persian Gulf oil producers and Russia invested heavily in refining capacity, capturing global diesel export market share. Kuwait National Petroleum Company built one of the world’s largest refineries at Al-Zour; the UAE expanded Ruwais; Iraq opened a new plant in Karbala; and Saudi Aramco constructed two refineries along the Red Sea. These investments more than doubled Middle East diesel exports between 2017 and 2025, making the region the world’s largest diesel exporter with a 19% global share, surpassing North America. Russia also boosted exports by a third through refinery upgrades.
That supply architecture has now been shattered. After joint US-Israeli strikes on Iran in February, traffic through the Strait of Hormuz was disrupted, forcing Kuwait, the UAE, and Iraq to slash exports. Escalating Houthi attacks have further squeezed Saudi Aramco’s Red Sea refineries—the main alternative route bypassing Hormuz. Meanwhile, Ukrainian drone strikes on Russian refineries have nearly halted Russia’s exports. “We are witnessing what may be the tightest diesel market in history,” said David Martin, senior oil market analyst at the IEA.
Western Refiners Can’t Fill the Gap
Western refining capacity has been starved of investment for decades, lured by the low-cost supply from the Middle East and Russia. National oil companies prioritized employment and energy security over returns, while Western majors have not built a new refinery in nearly 30 years. Since 2015, more than ten refineries have closed across the US and Europe. “We see the majors actually reducing their exposure to the sector because actual capital returns have been poor,” said Alan Gelder, senior vice president at Wood Mackenzie. The industry quip, he noted, is: “How do you turn a large fortune into a small one? Build a refinery.”
Even at near-full capacity and with output tilted toward diesel at the expense of gasoline and jet fuel, Western refiners cannot cover the shortfall.
Export Ban: Quick Fix or Global Shock?
An export ban would likely backfire. The American Petroleum Institute warned in a 2022 letter to then-Energy Secretary Jennifer Granholm that export restrictions raise domestic prices. Studies from the Center for Strategic and International Studies, the Dallas Fed, and Columbia University’s Center on Global Energy Policy reached the same conclusion. The structural problem is that US refining is concentrated along the Gulf Coast, with infrastructure designed for exports. Pipelines to other regions are already at or near capacity, and tight global tanker capacity limits flexibility. CSIS noted that Gulf Coast refiners facing unprofitable operations would cut runs, reducing domestic gasoline supply and pushing prices higher—the opposite of the intended effect.
Key Takeaways for Investors
- Diesel cracks stay elevated: Refining margins, especially for distillates, are likely to remain historically high as the supply gap persists. Refiners with diesel-heavy slates may outperform.
- Energy equities and commodities: Crude oil may see upward pressure from product shortages, while natural gas and coal could benefit as substitutes. Watch for demand destruction in emerging markets.
- Inflation and rates: Sustained diesel costs feed into freight, food, and industrial prices, complicating central bank easing cycles and supporting bond yields.
- Policy risk: An export ban would be a wildcard—bearish for US refiners, bullish for global product prices, and disruptive for global trade flows.
- Crypto and currencies: Dollar strength may persist on energy-driven inflation, while commodity-linked currencies like the CAD and NOK could outperform. Bitcoin may see mixed flows as a hedge against inflation versus a risk-off drag.
