US Diesel Prices Hit Record High at $6.51 per Gallon

The national average price for diesel in the US reached $6.51 per gallon on Monday, according to AAA data.

This is a historic high, surpassing the previous record of $6.5107 per gallon set on September 21, 2026.

Commodity strategist Giacomo Prandelli warned that the supply disruption has moved into a diesel market that 'no handshake can refill.'

Record-high diesel prices are affecting the domestic agricultural and logistics sectors, with farm fuel costs rising by $11 per acre for corn and $7 per acre for soybeans compared to last year.
