Diesel costs jump over $190 on some school bus fills as Trump-Putin Russian supply deal draws market doubt
Diesel prices have risen since the Iran war began, and the operators who buy it by the thousand gallons are eating the difference. Filling one standard Milwaukee school bus went from about $260 to over $450, and Richmond-area districts are reporting the same squeeze on their budgets.
The surcharge lag
David Fifarek, senior director of business and transportation services at Milwaukee Public Schools, runs three-year contracts with private bus companies that buy fuel against an annual benchmark price tied to the CPI. "Just because diesel prices go up, it is not necessarily a dollar for dollar or cent for cent increase on our costs," he said. That benchmark structure softens the hit now and passes it through later when the contract resets.
Carriers without that kind of cushion are the ones sweating. In Pennsylvania, drivers and districts say small bus companies may not survive a prolonged run of high diesel. Any hauler running spot loads or thin surcharge language is in the same spot.
The Russian deal
Trump and Putin agreed last week for Russia to supply diesel to the US and global markets: over 300,000 tons immediately, then another 3 to 5 million tons from Russian refineries. The stated point was pulling US pump prices down.
The market isn't buying it. CHOSUNBIZ reported traders doubt the deal lowers US fuel prices, and Moscow claims its diesel export capacity will outpace the targets Trump announced. For a US jobber, nothing changes at the rack until those barrels actually land and refiners price them in. That could take weeks, if it happens at all.
Saudi supply risk
Brent was $105.43 a barrel and WTI $92.60, both down slightly from Monday's close but above last week. Crude topped $106 the day before easing. Traders are weighing Houthi attacks on Saudi Arabia against the prospect of Russian diesel relief.
Saudi Arabia's energy minister pledged to keep exports flowing, and the Saudis shot down Houthi missiles aimed at the kingdom. Crude could soften further if exports hold and the Russian supply materializes, and it could firm again if the attacks disrupt loadings.
On the demand side, Michigan Gov. Whitmer signed an executive order to support farmers as high diesel collides with harvest, a sign of how the distillate run is landing on ag and freight at the same time.
What to watch
Whether that first 300,000 tons of Russian diesel ships, and whether it moves US distillate prices at all. Saudi export continuity against the Houthi risk. And the small carriers and bus operators without real surcharge protection, who are closest to the edge if diesel stays where it is.
