Ascension within Glencore

Glasenberg joined Glencore in 1984, initially focusing on coal operations across South Africa and Australia. Between 1989 and 1990, he oversaw corporate offices in Hong Kong and Beijing before taking control of the coal department in 1991. By 2002, he was named chief executive officer. His career intersected with the history of Marc Rich & Co, the predecessor firm founded by the commodities trader Marc Rich, which operated under significant scrutiny during its active years.

Corporate Expansion and Mergers

A defining moment in his executive career was the 2013 finalization of the merger between Glencore and Xstrata. Initially structured as a merger-of-equals with Mick Davis, the deal evolved into a takeover after Qatar-based shareholders held out. The resulting entity, Glencore Xstrata, was valued at US$88 billion. Throughout this period, Glasenberg held directorships at various firms, including Minara Resources, Rusal, and Century Aluminum Co.

Exit and Legacy

Glasenberg retired from the chief executive role in 2021, succeeded by Gary Nagle. His final major actions included presidential meetings in Kazakhstan and Tajikistan and the acquisition of partner interests in a Colombian coal mine. Residing in Rüschlikon, Switzerland, he made headlines when his tax contributions following Glencore’s London Stock Exchange flotation allowed the local municipality to reduce resident tax rates. As of January 2025, he remains the largest shareholder of the company.
