Midwest Basis Spikes After BP Whiting Outage Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- Midwest refined product basis surged Tuesday (4/28), with sharp increases across ULSD and gasoline markets, as supply concerns lifted prompt values after a weekend power outage at BP Whiting Refinery. Chicago ULSD basis was assessed at a 48cts premium to May NYMEX ULSD futures, climbing 60.50cts on the session, with similar moves seen across the Buckeye Complex and Wolverine pipeline, according to DTN Energy data. Chicago CBOB gasoline basis also moved higher, rising 18cts to a 25cts premium to NYMEX RBOB futures, while Buckeye and Wolverine gasoline basis increased by 17cts on the day. In the Group 3 market, ULSD, commonly referred to as "X," strengthened by 15cts to a 6cts discount, while jet fuel, known as "Q," rose 14cts to a 30cts discount. Over the weekend, BP's 440,000-bpd Whiting refinery experienced a brief power outage that led to the shutdown of a processing unit and flaring activity. "Although it's not yet clear what the full impact will be, it's already adding pressure to refined products," a source familiar with Midwest trading said. "You've also got planned maintenance at the Marathon Robinson Refinery, which has been underway since mid-March, tightening supply further." In a statement, BP said the outage occurred the night of April 26 due to a systems-related power interruption and was not the result of operator actions. Power has since been restored and operations are stable, the company said. (c) Copyright 2026 DTN, LLC. All rights reserved.
