Refiner Stocks Match AI Rally as Fuel Supply Crunch Triggers 141% Index Surge

U.S. oil refiner stocks have surged 141% this year, matching the explosive gains that defined AI companies' market dominance—a parallel rise that highlights how both sectors are riding waves of supply-driven scarcity and investor speculation. Marathon Petroleum, Valero Energy, and Phillips 66 have climbed 151%, 144%, and 105% respectively year-to-date, eclipsing the broader market after global fuel supplies tightened dramatically. Wars in the Middle East and Ukraine have removed over 7 million barrels per day of refined products from international flows, pushing refining margins two to three times above historical averages from 2013 to 2019. Gasoline crack spreads—a key refining profitability measure—have jumped 60% from year-ago levels, while distillate and jet fuel spreads have more than doubled, driving operating margins to near-record levels.
