Prompt sub-octane CBOB offer levels in Group 3 rose from 11.5cts over September NYMEX at 10:30 a.m. ET to 12.50cts over by 2:00 p.m. ET. Chicago prompt sub-octane offers jumped to a 4cts premium over the same benchmark, from previous 6cts and 2cts discounts talked earlier on the day, according to market sources. The firming cash offers reflect immediate supply tightness across a regional distribution network that ships gasoline, diesel, and jet fuel from the Gulf Coast through the Midwest into the Chicago area. Although actual transaction volume remained sparse and bids lagged, refiners and traders pushed asking prices higher to protect prompt inventory locked behind the terminal suspension. "Refiners are looking at this as a wait-and-see situation, so sellers are holding out for higher prices," a Midwest fuels trader told DTN. "With product sitting locked in terminal front-end tanks, prompt availability gets very tight very quickly once existing holdings are lifted." Retail fuel prices also recorded sharp upward momentum across Midwest distribution networks. U.S. diesel on average jumped 19.7cts this week to reach a near three-month high of $5.454 gallon, Energy Information Administration data released Tuesday showed. Midwest retail diesel posted the largest jump nationwide, escalating 25.4cts to $5.435 gallon during the week ended August 17. National average gasoline prices also climbed, rising 4.3cts to $4.049 gallon to snap two consecutive weekly declines, with Midwest regular gasoline surging 12.2cts to $3.938 gallon. Limited fuel availability in the Midwest was fueled by yesterday's explosion at the the Glenpool facility serves as a vital midstream junction for the 1,830-mile Explorer system, which transports refined petroleum products northward from PADD 3 into PADD 2. Explorer Pipeline said in a statement that local operations in Oklahoma have been paused to focus on "on-site reclamation and remediation process". The operational friction at Glenpool intersects with an already tight regional market, where recurring logistics bottlenecks have whipped cash prices around and forced distributors to scramble for prompt replacement barrels. Midwest fuel distribution channels have faced heightened volatility due to recent hiccups at Phillips 66's 356,000 bpd Wood River refinery in Roxana, Illinois, and throughput issues at the Lamar terminal pipeline junction near the Colorado-Kansas border. During Monday's blaze, a neighboring Phillips 66 facility that feeds into the Glenpool network temporarily halted operations as a safety precaution without sustaining site damage. Phillips 66 holds an equity ownership stake of approximately 30% in the Explorer system. Separately, ONEOK's Scott City terminal reported an outage affecting X grade and #2 diesel supplies. It was not clear if the outage was related to the Glenpool explosion. The domestic supply tightness reflects broader global refined product pressures, where gasoline, diesel, and jet fuel compete for limited processing capacity. Regional spot market vulnerability heading into the harvest season has been amplified by a worldwide scramble for shrinking distillate supply amid disruptions across Europe and the Middle East. NYMEX ULSD Crack Hits All-Time High on Supply Tightness The NYMEX-ULSD crack spread surged to an all-time high Tuesday (8/18), settling at $102.23 bbl as tight global diesel supplies; strong seasonal consumption and geopolitical disruptions continued to support refining margins. The crack, which measures the price difference between a barrel of NYMEX ULSD and West Texas Intermediate crude futures, surpassed the $100 bbl mark Tuesday morning well above the $42.01 bbl reported on February 27, the last trading session before the start of the U.S.-Israeli war with Iran. The spread also surpassed the previous record of $86.82 bbl reached in October 2022 following Europe's decision to ban Russian refined product imports. The front-month NYMEX ULSD futures contract settled Tuesday at $4.4371 gallon, the highest settlement on record. As trading volume rolled to a new month, October became the most actively traded ULSD contract on the day, with the October-November spread widening to 3.16cts gallon, the strongest backwardation registered this year, according to DTN data. The ULSD forward curve remains deeply backwardated, signaling strong demand for prompt barrels. September ULSD continued to trade at a premium to October as the market rolled into the next contract month. Global diesel availability has tightened as disruptions in the Middle East collide with continued Ukrainian attacks on Russian refining infrastructure. Recent domestic fuel shortages and intermittent refinery disruption in Russia have also contributed to the government's decision to restrict fuel exports. Meanwhile, Houthi attacks on Saudi energy infrastructure and continued uncertainty surrounding tanker traffic through key Middle Eastern waterways have added further risk to refined product flows. Strong overseas buying for U.S. diesel is also pulling barrels out of the domestic market. U.S. distillate fuel oil exports averaged 1.655 million bpd in May, the highest monthly rate since July 2017, when shipments averaged 1.750 million bpd, according to the latest monthly data from the U.S. Energy Information Administration. The combination of elevated exports, seasonal consumption and constrained overseas refinery output has intensified competition for U.S. distillate barrels, keeping NYMEX ULSD prices and margins at historically elevated levels. Phillips 66 Borger Refinery Exceeds Opacity Limit Phillips 66 reported an emission event at the Area B at its 149,000 bpd Borger refinery in Texas exceeded permitted levels, according to a filing with the Texas Commission on Environmental Quality. The event occurred between 2:05 p.m. CT Monday (8/17) and approximately 2:40 a.m. CT Tuesday (8/18), according to the initial filing released Tuesday. The Area B of the Borger refinery includes the Fluid Catalytic Cracking unites and Hydrofluoric Acid Alkylation units, which convert heavy gas oils and intermediate hydrocarbons into high-octane gasoline blending components and cracked gas streams. Opacity at the refinery's U40 facility reached an estimated 100%, exceeding the 35% limit listed in the filing. Phillips 66 said operations personnel took steps to minimize emissions and an investigation will be conducted to determine the cause of the incident. The Borger refinery primarily processes medium and heavy sour crude oil to produce gasoline, diesel and jet fuel. DTN reached out to Phillips 66 for additional details but did not get an immediate response. Flint Hills Reports Flare at Corpus Christi FCC Area Flint Hills Resources reported Tuesday (8/18) a refinery flare event at the FCC process area of its 269,500 bpd Corpus Christi West Refinery, according to a filing with the Texas Commission on Environmental Quality. The event occurred between 1:28 p.m. and 11:25 p.m. CT Monday (8/17), with emissions vented through the First Stage Flare. Estimated emissions included approximately 872 pounds of carbon monoxide, 775 pounds of sulfur dioxide, 329 pounds of benzene, 169 pounds of nitrogen oxides and 80 pounds of unspecified volatile organic compounds. The reported benzene and sulfur dioxide quantities exceeded their respective reportable limits listed in the filing. Flint Hills said personnel initiated measures to assess and minimize emissions following the incident. The cause of the event remains under investigation, the filing stated. The refinery primarily produces jet fuel, diesel and gasoline. DTN reached out to Flint Hills Resources for additional details but did not get an immediate response. Fire at Glenpool Pipeline Tank Farm Extinguished Firefighters put out on Tuesday (8/18) a blaze that broke out the previous day at the Explorer Pipeline tank farm in Glenpool, Oklahoma that ships gasoline, diesel and jet fuel from the Gulf Coast through to the Midwest and Chicago area, media reports said. Emergency response teams used specialized foam suppressants overnight to control the fire, preventing reignition across the smoldering infrastructure, the reports added. No injuries were cited. Local authorities also lifted a shelter-in-place order and surrounding precautionary evacuations after air monitoring services reported no ongoing public health hazards from smoke plumes. During the blaze, a neighboring Phillips 66 facility, which feeds directly into the Glenpool system, also halted operations as a precaution. Phillips 66 reported no structural damage to its site or impact from the fire. The operational collaboration with Explorer aside, Phillips 66 holds roughly a 30% stake in the 1,830-mile refined products pipeline system. EIA: U.S. Retail Diesel Up 19.7cts on Wk, Near 3-Mth High U.S. pump prices for diesel surged 19.7cts this week to reach a near three-month high of $5.454 gallon, Energy Information Administration (EIA) data showed Tuesday (8/18).
