US Diesel Hits Record $6 per Gallon on Iran Supply Shock

US diesel prices have hit an all-time high of $6 per gallon, driven by a supply shock linked to Iran, according to the Financial Times. The record price is already being felt across the economy, with fourth-generation Iowa farmer Mark Mueller warning that "we are endangering one of the strongest economic pillars that we have in this country." Diesel is the backbone of freight, agriculture, and heavy industry, so the surge threatens to raise costs for virtually all goods. The exact timing and duration of the supply disruption remain unclear, but the record level marks a critical stress point for US supply chains. No official government or industry response has been reported yet.

Global Impact

Economically, record US diesel prices act as a broad tax on consumption and production, likely adding to inflation and weighing on growth. Politically, the Iran-linked supply shock could intensify sanctions debates and Middle East tensions.
