Heating Oil Dips Toward $4.50 Amid Relief Measures and Supply Tightness
On 6 October 2026, US heating oil prices dipped toward $4.50 per gallon after President Trump signed an executive order expanding access to tax-exempt diesel. The order waives the off-road requirement for red-dyed diesel, allowing tax-free purchases for any use, aiming to ease tight market conditions that have kept prices elevated for weeks.
Despite the relief measures, heating oil remains near its record high of $5.20 reached in mid-September. US distillate inventories are at historically low levels, with recent readings near 105 million barrels, about 15% below year-ago levels. East Coast diesel reserves are nearly 29% lower than last year, raising concerns as winter approaches.
Global supply constraints further tighten the market, with disruptions in the Middle East, Russia's diesel-export restrictions, and China's suspension of October fuel exports contributing to the squeeze. Refinery maintenance and seasonal demand are expected to keep supplies tight through autumn, even as the new executive order and G7's release of 100 million barrels of diesel aim to alleviate pressure.
Valero Energy (NYSE:VLO), a pure refiner, benefits from tight diesel margins, earning the spread between crude costs and product prices. Its shares rose 4% on 1 October. Chevron (NYSE:CVX), an integrated major, reported record US refinery throughput of 1.07 million barrels a day at 97% utilization, positioning it to capture wide diesel margins alongside its crude production. Exxon Mobil (NYSE:XOM), however, saw little change in its stock price, highlighting the offsetting effects of crude and refining for integrated majors.
Looking ahead, heating oil prices could firm again if inventories fall further, export restrictions persist, or cold weather arrives early. Alternatively, prices could ease if emergency barrels reach the East Coast quickly, Russian and Chinese exports resume, or refinery maintenance concludes on schedule. Key events to watch include US inventory data on 7 October, the November heating oil contract's expiry on 30 October, Valero's third-quarter results on 22 October, and whether Russia extends its diesel export ban beyond October.
