Diesel crossed $5 again.
Regular gasoline is nearing the $4 threshold that many monitor closely, during the typical peak of summer demand.
Fuel markets are being squeezed from multiple directions at once. A recent escalation in tensions between the United States and Iran led to a sharp reduction in fuel availability across both American and European markets this week.
Diesel serves as the essential fuel for the majority of heavy trucks transporting goods nationwide, along with farming and construction machinery, making it vital to the U.S. economy. The current inventory shortfall is particularly alarming because stockpiles normally build during spring and early summer to prepare for winter heating demand. Instead, they are shrinking amid geopolitical turmoil.

The current crisis highlights the precarious nature of global fuel supply chains. With the United States and Iran locked in a new confrontation and Russia restricting exports, diesel markets are facing simultaneous supply shocks that have not been seen in decades. The lack of spare refining capacity means that even a minor disruption can have outsized effects on prices, as seen in the rapid increase over the past few weeks.
The combination of the Iran conflict and Russia's export restrictions has exposed a fragile supply chain that depends on steady refining output and global trade flows.
Normally, U.S. distillate inventories build during spring and early summer to prepare for winter heating demand. This year, they have been shrinking instead, due to a confluence of factors: reduced Russian exports after refinery attacks, robust economic activity, and the latest escalation with Iran threatening crude flows through the Strait of Hormuz. With limited spare refining capacity globally, the market remains vulnerable to further supply disruptions.
Adding to the pressure, the ongoing conflict between the United States and Iran has escalated over recent months, with military engagements disrupting shipping in the Persian Gulf. At the same time, Ukraine's continued strikes on Russian refineries have forced Moscow to curtail diesel exports, compounding the supply crunch. These twin crises have created a perfect storm for fuel markets, leaving little room for error in an already strained system.
A fresh round of fighting between the US and Iran caused fuel availability to plummet across American and European markets this week. A week earlier, Russia's government halted diesel exports following increased Ukrainian attacks on its refineries.
These shocks pushed wholesale prices upward, and retailers are now transferring those increases to consumers at the pump.
Consumers are feeling the pinch from higher prices, fueling expectations that the Federal Reserve may raise interest rates to control inflation. These price increases additionally highlight the difficult position of President Donald Trump, who faces midterm elections in November while trying to conclude a conflict he once predicted would be brief.
