LONDON: Independent trading houses are among the most active players in global energy and commodity markets but are not yet household names outside of the industry.

That could change in the case of the world’s biggest commodities trader Glencore which has enjoyed a surge in value to around $60 billion as it contemplates an initial public offering.

That value placed on it by Liberum Capital would place it among the 15 biggest FTSE-listed companies if it were to secure a London listing.

Louis Dreyfus is also looking at listing its commodity trading arm or a merger with rival Glencore, Les Echos reported earlier this week.

The following are the unlisted, world’s top independent traders.
