Cash-rich oil majors confront new reality after Middle East crisis

Big Oil's cash coffers have ballooned to unprecedented levels, thanks in part to record refining margins. The five largest Western oil companies - BP, Chevron, Exxon Mobil, Shell, and TotalEnergies - are on track to report combined third-quarter profits of around $53 billion, up from $48 billion in the second quarter and more than double year-earlier levels.

However, since the start of the Iran war in late February, oil majors have directed billions toward debt reduction rather than major new investments. This approach made sense early on, when energy markets were volatile and investors expected a short-lived conflict. Seven months later, the industry faces a protracted, low-intensity regional conflict with lasting consequences for global energy markets.

The refining boom is driven primarily by record US crack spreads, averaging about $63 per barrel this quarter. Exxon stands to benefit the most, given its refining capacity of roughly 4 million barrels per day - the largest among the majors. While investing in new refining capacity remains unattractive in Europe and North America due to challenging economics, companies are reassessing the value of geographic diversification.

Buyers increasingly seek reliable supplies, willing to pay a premium for them. Producers are re-evaluating the importance of location, with international oil companies directing capital toward new producing regions such as the Atlantic Basin, Africa, and Asia rather than concentrating investment in the Middle East. The industry must prepare for a world of higher geopolitical risk, longer supply chains, and a global push for energy security.
