Iran Conflict Sparks Diesel Price Surge as Control of Strait of Hormuz Remains Key Issue

The ongoing conflict in Iran has had a disproportionate impact on diesel prices compared to crude oil. According to recent data, the national average retail price of diesel is $5.50 per gallon, a staggering increase of over 40% since the war began on February 28. In contrast, the price of crude oil has risen by around 10%. This discrepancy in pricing affects farmers, who pay less for diesel due to tax exemptions and varying state prices.

The farm diesel crack spread has also widened significantly. The immediate future of diesel prices will depend on the outcome of the conflict. If hostilities cease with a reopening of the Strait of Hormuz, crude prices would likely decrease, narrowing the crack spread to some extent. However, experts warn that this may not happen soon due to low global diesel inventories and damaged Middle Eastern refineries.

A key factor in resolving the crisis is the control of the Strait of Hormuz. The Iranians are insisting on being given control of the strait as part of any peace deal. Vice President JD Vance has been pushing Ukraine to halt drone attacks on Russia's oil infrastructure, but this may not guarantee a freer flow of Russian diesel exports.

President Donald J. Trump is applying economic pressure by blocking the Strait of Hormuz, with Treasury Secretary Scott Bessent talking about new, tougher sanctions on Iran. The Iranians believe they have the upper hand and are preparing to endure severe economic hardship in hopes that Trump will blink first.
