The growth of American refinery stocks has particularly drawn attention in the current global fuel market, which is accompanied by Middle Eastern tensions and reduced supply from Russia. With oil prices rising in 2026, stocks of major American companies like ExxonMobil and Chevron have increased by about 40 percent. However, refinery stocks have significantly outperformed these companies.
Fuel Market Status and Supply Reduction
Currently, over 7 million barrels per day of refined product production have been lost from the Middle East and Russia. The wars in Iran and Ukraine have created a major supply gap that capacities outside these regions cannot fill. This situation has led to a remarkable growth in American refinery stocks, surpassing those of major oil companies. Refining margins are reaching their highest historical levels.
Analysts and the Future of the Market
Analysts expect that the market situation will not return to normal soon. Marianne Mannan, President and CEO of Marathon Petroleum, noted in the second quarter earnings calls that gasoline and diesel inventories are at their lowest levels. On the other hand, Mark Lashier, CEO of Phillips 66, emphasized that this situation is more due to supply shock than demand.
Additionally, Phillips 66, Marathon Petroleum, and Valero each reported higher-than-expected profits in their earnings reports for the second quarter and forecasted that high margins will continue until the end of this year and even into next year. Given the inventory reductions and the lack of refinery capacity recovery in the short term, refinery stocks still have more growth potential.
Reports indicate that demand for refined products, especially in the United States, is increasing while inventories are at their lowest levels. Specifically, diesel inventories in August reached their lowest level since April 2005 and are also the lowest for this month since 1951.
