Chicago ULSD Basis Extends Decline, Falls 17.5cts Barani Krishnan DTN Refined Fuels Market Reporter SECAUCUS, NJ (DTN) -- The basis for Chicago ultra-low sulfur diesel (ULSD) plunged 17.5cts gallon against the futures benchmark Thursday (9/24), extending cash price weakness for fuels in the region amid talk of better product availability. Sliding futures values for diesel -- despite Midwest distillate inventories standing at a three-month low last week -- also weighed on physical markets. The 17.5cts slide in the differential for Chicago ULSD versus October NYMEX ULSD left the cash price at a discount of 22cts gallon against the benchmark, DTN price data showed. On Wednesday (9/23), the discount was 5cts. The basis for Buckeye and Wolverine pipe ULSD fell 15.5cts each to a 18.5cts discount to the October NYMEX ULSD futures contract, compared to a 3cts discount reported in the prior trading session. In the Midcontinent, Group 3 ULSD basis slipped 2.5cts to a discount of 6cts to the same benchmark. Meanwhile, Chicago jet fuel basis fell 5cts, widening to a 45cts discount to the NYMEX ULSD for October delivery from a 40cts discount seen the prior session. Group 3 jet fuel basis tumbled 25cts to a discount of 65cts to the same benchmark, compared to Wednesday's 40cts discount. The downward momentum in distillate values came amid market chatter that ExxonMobil's 275,000 bpd Joliet refinery in Channahon, Illinois had begun bringing processing units back online after back-to-back power outage and flooding disruptions. The operational progress outweighed tightening inventory fundamentals reported by the Energy Information Administration (EIA) on Wednesday. Midwest distillate stocks fell 1.6 million bbl during the week ended September 18 to 27.2 million bbl -- the lowest level since mid-June. The stock draw was driven by a sharp 11 percentage-point drop in PADD 2 refinery crude utilization to 89%, as crude throughput fell to 3.802 million bpd. Regional jet fuel inventories held flat on the week at 8 million bbl. (c) Copyright 2026 DTN, LLC. All rights reserved.
