Oil Futures Up on Gulf Concerns; Diesel Crack Strong Barani Krishnan DTN Refined Fuels Market Reporter SECAUCUS, NJ (DTN) -- Crude prices climbed early Wednesday (9/23) on the lack of a prompt resolution to the Gulf war. Diesel futures slipped on U.S. President Donald Trump's proposed domestic ban on diesel exports even as cracks for the fuel remained strong on global supply worries. By 9:36 a.m. ET, NYMEX WTI crude for November delivery rose $0.63, or 0.71%, to $91.15 bbl. The session high was $91.43. ICE Brent for November delivery moved up $1.29, or 1.32%, to $100.54 bbl. It reached as high as $100.80 during the session. Crude benchmarks rose amid concerns about the situation in the Gulf after Trump cautioned Tuesday that further U.S. military action remained an option against Iran despite the first face-to-face talks in months between White House and Iranian government representatives on Tuesday on the sidelines of the U.N. General Assembly in New York. Downstream, NYMEX ULSD for October delivery eased $0.0972, or 2.32%, to $4.8449 gallon. It peaked at $4.9719 during the session. The diesel crack remained around $118 bbl, holding near historic high levels compared to the traditional 5-year average of roughly $20 to $30 bbl. The crack saw a further boost after U.S. Treasury Secretary Scott Bessent said the administration was evaluating whether a full or partial ban on U.S. diesel exports would be feasible after Trump backed the idea Tuesday as an option to bolster domestic supply. European low-sulfur gasoil crack spread over Brent crude, meanwhile, expanded to a record $95 bbl. RBOB for October advanced $0.0379, or 1.01%, to $3.5254 gallon. The high for the day was $3.5698. The U.S. dollar index gained 0.311 points to 100.630 against a basket of currencies. Industry data from the American Petroleum Institute reported a 1.786 million bbl build in U.S. crude inventories for the week ended September 18, defying expectations for a draw. Official inventory figures from the U.S. Energy Information Administration are scheduled for release at 10:30 a.m. EDT. (c) Copyright 2026 DTN, LLC. All rights reserved.
