The top U.S. derivatives regulator subpoenaed Goldman Sachs Group Inc. and JPMorgan Chase & Co. for documents relating to their warehouses for aluminum and other metals, Bloomberg News reported yesterday. The Commodity Futures Trading Commission has requested documents dating to the start of 2010 about the banks’ commodity warehouses. Glencore Xstrata Plc, which owns warehousing business Pacorini, also received a subpoena. MillerCoors LLC, Encore Wire Corp. and other metal users have complained about long queues and artificially high prices at the warehouses, particularly for copper and aluminum.
