The benchmark price used for most fuel surcharges fell the most in a week in more than three years, declining 20.5 cents/gallon to $5.403/g. This is the largest slide since a 22-cent decline on December 22, 2022. The Department of Energy/Energy Information Administration average weekly retail diesel price has been steadily increasing over the past year, but this week's drop marks a significant shift in the market.
The decline is part of a larger trend that has seen futures markets for ultra-low sulfur diesel (ULSD) contract on the CME commodity exchange experience wild fluctuations. The ULSD contract collapsed by 66.6 cents/gallon on April 8, following the announcement of a ceasefire in the Iran war, and has since experienced several days of significant price swings.
Despite these fluctuations, s expect diesel prices to continue falling if peace talks between the US and Iran are successful. The current price of ULSD is $3.5409/g, which is 26.75 cents/g less than its peak after the April 8 collapse.

The disconnect between futures markets and physical markets is a significant issue in the oil industry, with many experts arguing that physical markets provide a more accurate reflection of where the market is today. For example, dated Brent crude, the physical version of the world's crude benchmark, traded at approximately $105/barrel on Monday.
However, the price of Brent on commodity markets for June barrels was significantly lower than this, at around $10/b less. This discrepancy highlights the challenges faced by oil market analysts in predicting prices and has significant implications for consumers of diesel fuel.
The jet fuel market is also closely tied to diesel prices, with both being distillates that tend to move in the same direction relative to Brent, the global crude oil benchmark. The current price of jet fuel is $200 per barrel, which is a significant increase from its pre-war levels.
s such as Paul Sankey and Dan Pickering have warned that if peace talks between the US and Iran are successful, oil prices could drop significantly. Sankey has argued that the current price of jet fuel reflects a reality where $200 per barrel is no longer sustainable.
The impact of this on diesel prices will be significant, with many consumers facing higher costs at the pump. As such, it is essential for s and policymakers to closely monitor the situation and provide guidance to consumers.
In conclusion, the recent drop in diesel prices marks a significant shift in the market, with many experts expecting further declines if peace talks between the US and Iran are successful.
s expect oil prices to drop further if peace talks succeed in Iran war.
