CFTC subpoenaed HSBC Bank USA for documents on metals trading

``The Commodity Futures Trading Commission issued a subpoena to HSBC Bank USA in January seeking documents related to the bank's precious metals trading operations, HSBC said in its annual report and accounts statement on Monday... HSBC was one of a number of banks named in lawsuits filed in U.S. courts last year alleging a conspiracy to manipulate gold, silver, platinum and palladium prices, plus precious metals derivatives, during the daily precious metals fixes.''
