Diesel prices slide 16.5 cents post-election as geopolitical risk eases

Diesel prices declined sharply in the week following the election, with the Department of Energy benchmark falling 16.5 cents per gallon to $6.127/gallon, marking the lowest level since mid-October. This downturn reflects market expectations of reduced military escalation in the Middle East, with traders unwinding risk premiums built into commodity futures. Ultra low sulfur diesel (ULSD) futures fell from $4.42/gallon at the start of November to $4.21/gallon by Monday and $4.14/gallon by Tuesday.

However, the rally masks significant underlying vulnerabilities in global supply. Bank of America Merrill Lynch's analysis reveals that global oil supply disruptions have reached record levels in 2026, with production shortfalls exceeding anything in historical data since 1965. Strategic inventories across OECD economies are declining rapidly, particularly in China, leaving the market with substantially less cushion against future shocks.

The direction of the US-Iran war remains central to oil price evolution over the next 12 months. For supply chain professionals, this creates a critical decision point: the near-term relief in fuel surcharge costs is real, but it is built on geopolitical assumptions that could shift quickly. Organizations should capitalize on the current price environment to lock in medium-term fuel costs where possible, but also stress-test sourcing and transportation plans for scenarios involving renewed Middle East tensions or supply disruptions.
