Midwest ULSD Discounts Narrow on Renewed Iran Attack

SECAUCUS, NJ (DTN) -- Midwest ultra-low sulfur diesel (ULSD) basis
differentials narrowed Thursday (6/25), aligning with rallying NYMEX futures,
after an Iranian attack on a cargo ship in the Strait of Hormuz reignited
geopolitical risk premiums.
Chicago ULSD was talked at a discount of 27cts gallon to the August NYMEX
ULSD contract, narrowing by 14cts on the day. This rebound erased a significant
portion of Wednesday's slide, snapping the downward pressure caused by regional
inventory builds.
Wolverine and Buckeye Complex ULSD values strengthened alongside Chicago
spot prices. Buckeye/Wolverine ULSD was talked at a discount of 24cts gallon to
the August NYMEX ULSD contract, narrowing by 11cts on the day.
The turnaround across Midwest ULSD came after the rally in August NYMEX
ULSD, which rose almost 4% on the day after the Iranian strike on a
Singapore-flagged vessel off Oman raised concerns about Middle East peace
initiatives.
The basis strength bypassed localized fundamentals, which had previously
weighed on regional fuel values after a 900,000 bbl build in PADD 2 distillate
inventories reported for the week ended June 19 by the U.S. Energy Information
Administration.
