MIAMI, FL (DTN) -- Pacific Northwest Sub Octane Regular basis weakened
Monday (6/1), falling from last week's sharp rally as selling interest emerged
and the market eased from elevated levels.
PNW Sub Octane Regular basis fell by 7cts to 30.5cts premium to July NYMEX
ULSD futures from Friday's 37.5cts premium, according to DTN data.
An offer was heard at 31cts premium to July NYMEX ULSD futures, pulling the
market lower after values surged last week on tight regional supply, refinery
disruptions and flaring activity across the U.S. West Coast.
The decline followed a strong move higher on May 26, when bids were heard at
24cts, 30cts and last at 36cts premium, lifting the market from a previously
pegged 16.5cts premium.
Despite Monday's decline, West Coast supply concerns continue to support the
broader market as traders monitor refinery operations, flaring activity and
reduced regional production capacity following refinery closures and planned
shutdowns.
