Midwest ULSD Basis Widens as Futures Surge on Iran Risk

   DAVENPORT, FL (DTN) -- Midwest ULSD differentials widened sharply Monday 
after the April NYMEX ULSD futures contract saw the steepest increase of the 
session, rising by more than 14% as traders priced in heightened geopolitical 
risk tied to Iran and renewed concern over potential disruption to crude flows 
through the Strait of Hormuz.

   The futures-led advance injected significant risk premium into distillates, 
lifting flat price levels across the complex and pressuring regional cash 
markets to adjust.

   According to DTN data, Group 3 ULSD weakened 9.25cts on the session to a 
22cts discount to April NYMEX ULSD futures. Chicago ULSD declined 6cts to a 
7cts discount, leaving Group 3 at a 15cts discount to Chicago.

   The widening discounts reflect a sharp rise in flat price rather than a 
sudden deterioration in Midwest supply fundamentals. When futures advance 
aggressively, rack markets often recalibrate by deepening discounts as buyers 
hesitate at elevated replacement costs and spot liquidity temporarily slows.

   PADD 2 remains insulated from direct crude supply disruption given its 
reliance on Canadian and domestic pipeline flows. However, global diesel 
balances are more sensitive to geopolitical risk. Any sustained threat to 
Middle East export routes would tighten the Atlantic Basin distillate market 
and could eventually lend support to inland pricing if Gulf Coast values 
strengthen and pull barrels outward.

   "This is a futures-driven move," a source familiar with the Midwest market 
said. "If the Gulf firms and export demand builds, basis will follow. Until 
then, the cash market is just adjusting to the higher flat price."

   Market participants will continue monitoring whether geopolitical tension 
translates into sustained physical tightening or remains confined to risk 
premium embedded in futures contracts.
