Analysis: U.S. Refining Margins Soar on Gasoline Shortage Karim Bastati DTN Analyst VIENNA (DTN) -- The 3:2:1 crack spread versus WTI broke the $70 bbl mark in intraday trading Thursday (7/17), the first time it has reached that level on record. As U.S. fuels inventories are rapidly shrinking, the spread in late June soared eclipsing its Iran-war highs from May and surpassing the previous record set in April 2022 during Russia's invasion of Ukraine. The divergence between crude oil and oil product futures was partly brought upon by the sudden resurgence of crude supply from the Middle East, even as global refinery runs were still at multi-year lows. Over the past four months, the largest oil supply disruption in history has eroded crude demand much more significantly than consumer's fuel demand. At the same time, fuels supply was just as affected as crude supply, and all this came against a backdrop of the global crude market tilting into record oversupply at the beginning of the year while the refined products balance remained level. The resurgence of Persian Gulf exports last month consequently sent crude prices plunging, while product futures held on to a significant portion of their war-gains. On July 2, when oil prices reached their post-war nadir ahead of the most recent re-escalation in fighting between the United States and Iran, front-month NYMEX WTI crude futures contract contract closed at $68.69 bbl, up 2.5% from February 27 close, the last trading day before the start of the U.S.-Israeli war on Iran began. ULSD futures in contrast, closed at $3.1822 gallon, up 19%, and RBOB was up 40% from pre-war levels at $2.9173 gallon. Another main driving force behind this uneven price development was the unprecedented rate of depletion in U.S. fuel inventories, particularly gasoline, which within three months plummeted from a five-year seasonal high to a 14-year seasonal low. Nationwide gasoline stockpiles fell to 210.5 million bbl last week, the least for this time of year since 2012, down 9.6% year-on-year and 8.4% below the five-year average. The pace of gasoline inventory draws since early April was three to four times faster than is typical for the season and came as a direct result of the Strait of Hormuz supply crisis. Refined product exports soared during the Strait supply disruption, further tightening inventories, while U.S. refiners optimized operations toward maximizing yields of products most affected by the crisis, including jet fuel at the expense of gasoline output. U.S. refiners have little scope to ramp up crude throughputs given utilization is already near maximum capacity. A sustained global supply disruption caused by a renewed conflict, just as demand is reaching its seasonal peak, will have inventories dwindle fast and give them little room for error. All this comes after months of margin-incentivized break-neck pace refining, which greatly increases maintenance needs and outage risks. Given the recent trajectory of crack spreads, domestic refiners will have no reason to slow down -- at least not voluntarily. (c) Copyright 2026 DTN, LLC. All rights reserved.
