The global rout in commodities prices has left Trafigura, one of the world’s biggest commodities traders, none the worse for wear. In 2015, the privately held company notched $1.1 billion of profit, a 6.4% increase compared to 2014, according to it most recent annual report. Co-founded in 1993 by Claude Dauphin, it trades oil and petroleum, as well as metals and minerals. Oil is its mainstay, however, and it moves 3 million barrels a day, worth nearly 3 percent of the world’s total oil production annually. Trafigura has not been without controversy. Dauphin, a former metals trader for Marc Rich + Co, spent nearly six months in an Ivory Coast prison between 2006 and 2007, for a dispute over the company’s dumping of toxic waste in that country. In 2014 Dauphin stepped down from his role as CEO, following a lung cancer diagnosis, and was replaced by company insider Jeremy Weir. Dauphin died in late 2015 at age 64.
