The Israel-Hamas conflict is causing uncertainty in the global oil supply chain. This could potentially disrupt oil transportation routes, impacting the availability of oil on the global market and driving up oil prices. As Marathon Oil is an energy company primarily involved in the exploration, production and marketing of oil and natural gas, its financial performance is highly sensitive to changes in oil prices. Therefore, the rise in oil prices could lead to increased revenues and profits for the company, positively impacting its stock price.
