PNW Sub Oct Reg Basis Falls 7cts on Lower Offers Kristina Davis DTN Refined Fuels Market Reporter 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.
