In this article, we look at the 13 Best Oil Refinery Stocks to Buy Right Now.

Investors are keeping their eyes on the global oil market while staying on their toes, amid a fresh wave of geopolitical tensions and supply-side shifts. On August 5, 2025, oil prices declined sharply as OPEC+ decided to increase production by 547,000 barrels per day for September. Brent Crude prices declined to $67.64, with WTI settling at $65.15. Prices for both hit their lowest in the past week.

Meanwhile, U.S. President Donald Trump threatened new tariffs on India over its Russian oil imports, reigniting trade tensions. In response, New Delhi showed a strong stance, indicating a growing rift. Oil prices fell further on August 6, amid speculation about progress in U.S.-Russia talks over the Ukraine war, easing fears of supply disruptions. However, prices rebounded slightly on the next day amid signs of steady U.S. demand and a larger-than-expected decrease in U.S. crude inventories. U.S. crude stockpiles dropped by 3 million barrels in the week ended August 1.

Yet, uncertainty remains over Trump’s planned summit with Putin, potential secondary sanctions on China, and volatility in global oil demand forecasts.

With this backdrop in mind, let’s move on to our list of the 13 Best Oil Refinery Stocks to Buy Right Now.
