The US national average retail diesel price fell below $6 a gallon on November 14 to $5.998, after two months above that level. Prices had hit a record $6.519 on September 22 amid disruption from the US-Israeli war with Iran and Ukrainian strikes on Russian refineries.
Easing geopolitical tensions and seasonal demand weakness drove the decline.
Lower diesel costs reduce freight and fertilizer-related expenses for grain and feed logistics and ease pressure on biofuel margins. The move reflects falling energy prices rather than a feed-specific supply change.
After 80 past bearish macro events, ULSD / Diesel moved a median -1.4% over 5 sessions (39% higher; middle half -5.7% to +1.7%), and -1.5% over 20.
