Diesel Squeeze: Rising Prices as Distillate Exports Surge and Inventories Tighten
May 14, 2026
Concerns have emerged around potential disruptions to crude and product flows through the Strait of Hormuz, which averaged 20 million barrels per day in 2025—about 25% of global seaborne oil—since tensions with Iran began to escalate.1 As seen in today’s Chart of the Week, as the conflict with Iran has persisted, the U.S. has been exporting distillates at the highest rate in at least five years, while inventories have simultaneously reached lows.2 Given these market dynamics, diesel prices at the pump have been climbing, most recently now approaching levels last seen in June 2022 during the peak of the Russia-Ukraine war.3
While the average consumer is not buying diesel at the pump, it is often considered “the lifeblood of the economy,” and this spike in diesel prices will place pressure on supply chains and trickle down to the consumer.4 Auto transport costs are approximately 25% fuel-related,5 and diesel prices are up nearly 60% since the start of the year.6 This uptick in transport costs affects many products that need to move across the U.S., potentially putting upward pressure on items such as manufacturing, building products, groceries and more. Additionally, even if prices ease in the near-term, higher transport prices could persist, as freight companies sign long-term diesel supply contracts that can remain in their cost structure for months.
Key Takeaway
The U.S. has become a major distillate exporter amid ongoing Middle East tensions, driving inventory levels down and raising diesel prices to recent highs. If this market dynamic continues, consumers may feel upward pricing pressures across the economy due to higher freight and transport costs for moving crucial goods and commodities.
