Global Fuel Squeeze Triggers U.S. Refiners Stocks Rally

In the midst of escalating tensions in the Middle East and Russia's conflict with Ukraine, global fuel markets have tightened, causing a surge in U.S. refiner stocks. ExxonMobil and Chevron, the major U.S. energy companies, have seen their stocks climb about 40% each in 2026, but U.S. refiners have outperformed the majors. Phillips 66, Valero Energy, and Marathon Petroleum are among the refiners that have more than doubled in value this year due to a severe shortage of refined products.

The wars in Iran and Ukraine have created a significant supply gap that can't be filled by capacity outside the Middle East and Russia. As a result, refining margins have hit record highs, and the market is expected to take longer to normalize. Marathon Petroleum's CEO, Maryann Mannen, noted that global product balances are extremely tight, with inventories of gasoline and diesel at historic lows.

Phillips 66 CEO Mark Lashier added that the situation is more of a supply shock than a demand shock, with significant refining capacity offline and low stock levels. All three refiners, along with their industry peers, have reported strong earnings and high margins, with analysts currently signaling a moderate buy for the stocks.

However, the market seems to be overvaluing the stocks, as their 12-month price targets are lower than their current share prices, indicating that continued strength may be priced in faster than Wall Street models. The outlook for the fuel markets remains grim, with refinery throughputs reaching a summer peak of 81.4 million barrels per day in August, but still 4.2 million bpd lower than a year ago.
