The U.S. Department of Justice charged two current traders and one former metals trader for their alleged participation in a racketeering conspiracy over eight years. Gregg Smith and Michael Nowak -- both at JPMorgan JPM, +0.87% -- and Christopher Jordan, who left in 2009 and worked at other banks after -- were charged. The indictment alleges that between May 2008 and August 2016, the defendants engaged in widespread spoofing, market manipulation and fraud for gold, silver, platinum and palladium futures contracts while working on the precious metals desk at what the DOJ calls Bank A. Nowak's lawyers in a statement said he did nothing wrong and expect him to be exonerated. Reuters reported last week that Nowak and Smith were on leave, and two former JPMorgan traders, John Edmonds and Christian Trunz, have pleaded guilty to federal charges.
