CFTC subpoenas metal warehouse companies

• The Commodity Futures Trading Commission has reportedly subpoenaed Goldman Sachs (NYSE:GS), JPMorgan (NYSE:JPM), Glencore Xstrata (OTCPK:GLCNF) and their subsidiaries for documents relating to warehouses they operate for aluminum and other metals.
• The agency has requested information dating back to January 2010; it also wants documents relevant to the companies' relationships with the London Metals Exchange.
• The CFTC's investigation follows allegations that the activities of warehousing companies have artificially boosted the price of metals, particularly aluminum.
• Earlier speculation said the CFTC had sent subpoenas to an unnamed metals warehousing firm.
