G ary Fegel is a Swiss billionaire who made his fortune as a top trader at the commodities and mining giant, Glencore. He joined the company and rose to become one of its most senior and successful traders, eventually co-heading the aluminum and alumina trading departments. He was a key member of the company's powerful inner circle of partners.

Fegel became a multi-billionaire after Glencore's massive initial public offering in 2011, which turned its top partners and traders into some of the wealthiest people in the world. He left the company a few years after the IPO to start his own private investment firm, GMF Capital. Through his family office, he now manages a diversified portfolio of investments, with a particular focus on real estate and private equity. His story is a prime example of the immense wealth generated by the top traders at the secretive and powerful Swiss commodities house.
