Exxon Mobil Corp. and Chevron Corp. are using their substantial profits primarily to pay down debt, signaling a cautious approach to the sustainability of current high energy prices.

While both companies reported significant earnings, they opted against large increases in share buybacks. ExxonMobil's refining profits hit $4.1 billion, though this fell short of analyst expectations. This strategy reflects a wariness about how long the price rallies, fueled by geopolitical events, will persist.

This approach contrasts with broader concerns about "Big Oil's" windfall profits contributing to global inflation. The companies' decisions suggest a focus on financial stability over immediate shareholder returns, a move that could be influenced by the unpredictable nature of energy markets and potential future economic downturns.
