"in a curious twist, the settlement letter revealed that the former members of the manipulation cartel have turned on each other", and that Deutsche Bank would provide documents implicating other precious metals riggers. To wit: "In addition to valuable monetary consideration, Deutsche Bank has also agreed to provide cooperation to plaintiffs, including the production of instant messages, and other electronic communications, as part of the settlement. In Plaintiff's estimation, the cooperation to be provided by Deutsche Bank will substantially assist Plaintiffs in the prosecution of their claims against the non-settling defendants."

Overnight we finally got a glimpse into what this "production" contained, and according to documents filed by the plaintiffs in the class action lawsuit, what Deutsche Bank provided as part of its settlement was nothing short of "smoking gun" proof that UBS Group AG, HSBC Holdings Plc, Bank of Nova Scotia and other firms rigged the silver market. The allegation, as Bloomberg first noted, came in a filing Wednesday in a Manhattan federal court lawsuit filed in 2014 by individuals and entities that bought or sold futures contracts.
