Oil prices and energy stock volatility explained

The relationship between crude oil prices and energy stocks is complex and varies depending on a company's business model. Upstream producers, such as independent exploration and production companies, typically see direct benefits from rising oil prices as their realized selling prices increase. In contrast, refiners may experience mixed results; while higher oil prices can increase revenue, they also raise the cost of feedstock, meaning profitability depends on the crack spread between crude costs and refined product prices.

Integrated majors like Exxon Mobil and Chevron manage both production and refining, which can allow downstream operations to offset some gains from upstream price moves. Additionally, oilfield service companies are indirectly affected, as their revenue depends on the capital spending and drilling activity of producers.

Historically, oil price volatility is often driven by geopolitical shocks that threaten supply. Major historical examples include the Iranian Revolution and the subsequent Iran-Iraq War, which caused production to collapse, and the 1990 invasion of Kuwait by Iraq, which put millions of barrels of Middle Eastern production at risk. These events demonstrate that market prices often react to the perceived risk of supply loss even before physical shortages occur.
