NYMEX ULSD Crack Hits All-Time High on Supply Tightness Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- 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.
