‘Science fiction’: Transport companies — the backbone of economy — are sounding alarm on fuel prices

CNBC reports that diesel prices have reached an all-time high of about $6.31 per gallon, citing AAA data. The article says diesel is more than 70% higher than a year ago, with analysts attributing the move to a supply shock linked to the US war with Iran. Transportation firms describe this as an unusual and volatile fuel-cost environment, warning that profitability is likely to come under pressure.

J.B. Hunt’s finance chief, quoted in the piece, links the higher diesel bill to an expected earnings hit of 5% to 10% from the second to the third quarter. The article also points to GasBuddy’s head of petroleum analysis, who warns diesel prices could push higher in the next few days, with regional estimates including around $7/gal in parts of the Midwest and much higher levels already observed in California.

The piece frames transportation as economically important, noting the sector added $1.9tn to US economic output in 2024 (over 6% of enhanced GDP, citing the Bureau of Transportation Statistics). It also argues that while retail sales rose 1.2% from July to August, higher fuel costs may ultimately become a drag on the consumer by feeding through more broadly from farmers and transporters to prices.

What to watch next is whether these diesel-cost pressures persist long enough to influence consumer price dynamics, and whether they feed into expectations for monetary policy through higher perceived inflation risk.
