Glencore says it expects to report about $3.3 billion in first-half profit from its marketing division, a sign that extreme volatility across oil and commodity markets created unusually strong trading conditions. The update points to a standout period for the company’s trading business as geopolitical tensions tied to Iran sent prices moving sharply.

The marketing unit is the part of Glencore that profits from buying, selling and moving commodities around the world. When markets become more volatile, trading houses can benefit from wider price dislocations, rapid shifts in supply expectations and stronger demand for risk management across energy and raw materials.

In this case, the turmoil linked to the Iran conflict appears to have delivered one of the company’s strongest trading stretches in recent years. Oil markets were especially sensitive, with war-related uncertainty adding pressure to prices and increasing the value of well-timed trades and logistics.

The forecast underlines how major commodity traders can perform well during periods of disruption, even as instability creates broader concerns for producers, consumers and the global economy. For Glencore, the expected first-half result shows how a turbulent market environment translated into a sharp lift for its trading earnings.
