Do Seven Sisters Fuel Conflicts Around the World?

The Seven Sisters, a group of seven major Western oil companies that dominated the international petroleum industry during much of the 20th century, symbolized the concentration of corporate power over energy resources. Today, a broader question deserves attention: do powerful commercial interests benefit so substantially from conflict that they have an incentive to sustain geopolitical tensions?

The military-industrial complex, Wall Street, media houses and shipping companies operate in different sectors, yet conflicts can create lucrative opportunities for all of them. Defence contractors may secure additional orders, financial markets experience heightened trading activity, media organizations attract larger audiences, and shipping companies charge higher rates to reflect security risks. Oil producers and traders may also benefit from rising prices, although others suffer substantial losses.

The US-Israel war on Iran, which began on February 28, 2026, provides a compelling case for examining this hypothesis. Disruptions to energy supplies and shipping through the Strait of Hormuz have intensified volatility in global oil markets. On October 26, West Texas Intermediate (WTI) crude settled at US$101.76 per barrel, while Brent crude closed at US$115.81. The resulting differential of approximately US$14 illustrates how geopolitical disruptions can reshape commodity markets. However, price movements alone do not establish manipulation or prove that commercial interests caused the conflict.

The more consequential question is whether these beneficiaries merely exploit wars or also influence decisions that prolong them. Answering it requires examining corporate lobbying, political financing, defence contracts, media ownership and the relationships between business interests and policymakers. Profiting from a conflict is not, in itself, evidence of having engineered it.

The human and economic costs of war are enormous. Ordinary citizens face higher energy bills, inflation, disrupted trade and insecurity, while particular companies may enjoy exceptional profits. These unequal outcomes raise legitimate questions about accountability and the influence of vested interests over public policy.

The Seven Sisters no longer exercise the same dominance they once did, but the wider relationship between corporate power and geopolitical conflict merits scrutiny. The essential question is not simply who profits from war, but whether those profits influence decisions about when wars begin—and when they end.
