New York, November 29, 2010 – GFI Group, Inc (NYSE: “GFIG”) has been voted Commodity Broker of the Year 2010 by Commodities Now magazine in this year’s Commodity Business Awards. GFI is a leading provider of wholesale brokerage, clearing services, electronic execution, and trading support products for global financial markets.

Commodity Broker Award of the Year 2010 is presented to the traditional (non-position taking) commodities broker that has shown consistent innovation and product development over the last twelve months.

As the role of the traditional broker continues to evolve, Commodities Now looked for brokers that have challenged the status quo, developing new ways of interacting with clients, enhancing product lines, engaging with the industry and its regulators, and providing additional trading and clearing services.

Colin Heffron, President of GFI Group, said: “We are honoured to receive this prestigious award as recognition of our commitment to serve our clients with the highest quality service and products that meet their evolving needs” and added, “Our people at GFI, Amerex , StarSupply and Trayport strive to provide the best that can be offered in the commodities sector”.

The Award process entailed a submission to a panel of editors, from which they selected and drew a list of nominees, where market practitioners (worldwide) were then asked to vote for companies whom they believed deserved recognition and reward for advancing commodity business expertise.

GFI Group, Amerex, StarSupply and Trayport provide access to global energy, commodities, power and emissions markets through a hybrid approach that combines voice brokering with state-of-the-art electronic trading platforms: EnergyMatch®, EnergyMatch® Europe, and Trayport Global Vision Trading Gateway®.
