The new evidence is derived from 350,000 pages of bank documents and 75 audio tapes handed over by Deutsche Bank as part of the accord. The traders aren’t identified by name in the filings.

The recorded chats sprinkled with “dude,” “bro,’’ and assorted obscenities are a “smoking gun” bolstering claims that traders rigged silver prices, impacting jewelry prices, silver investments and the earnings of mining companies that sell raw materials to refiners, the plaintiffs say. The traders acted against their own clients’ interest, triggering stop-loss orders and front-running customers trades, according to the documents.

They also gave code names to certain techniques, according to the documents, which explain that “blade” meant placing a series of small orders close to each other in price, and “muscle” referred to placing large orders -- usually when they knew the market was illiquid.

Lawyers representing traders who allege they were ripped off by a group of colluding global banks filed eye-popping evidence in a Manhattan Federal Court yesterday showing that even as global banks were being criminally probed for rigging currency markets, they continued to engage in rigging the silver market, with a UBS trader referring to the group as the “mafia.”

Numerous trader conversations confirming the sharing of insider information among traders at global banks were provided to the court yesterday, including the following between traders at Barclays and Deutsche Bank on April 6, 2011 — where one trader suggests the collusion amounts to “one team one dream.”

Eight months after Deutsche Bank AG settled a lawsuit claiming it manipulated gold and silver prices, documents it disclosed as part of the accord provide “smoking gun” proof that UBS Group AG, HSBC Holdings Plc, Bank of Nova Scotia and other firms rigged the silver market, plaintiffs claim.

Deutsche Bank AG has agreed to pay $60 million to settle private U.S. antitrust litigation by traders and other investors who accused the German bank of conspiring to manipulate gold prices at their expense.

Deutsche Bank denied wrongdoing. The bank in October agreed to pay $38 million to settle similar litigation over alleged silver price manipulation.

Not surprisingly, one of the silliest explanations for last week’s sharp decline in the gold price appeared in an article posted at the Zero Hedge web site. According to this article, the only plausible explanation for the decline is rampant manipulation while China’s markets were closed for the “Golden Week” public holidays*.

Large global banks targeted in a lawsuit alleging price fixing in the gold market, including Canada’s Bank of Nova Scotia, will have to turn over internal emails and other correspondence spanning several years as the case moves ahead, says Daniel Brockett, the New York lawyer who is spearheading the U.S. lawsuit.

“They have to produce all the relevant emails and chat room instant messages, however they communicated with each other,”

“The ruling is a major victory for the plaintiffs because it upholds the core anti-trust claim against the five fixing banks, and the statutory commodity manipulation claim against the five fixing banks,”

A U.S. judge has dismissed UBS Group AG (UBSG.S) as a defendant in a lawsuit accusing big banks of conspiring to fix silver prices and exploit price distortions at investors' expense.

In a decision made public on Tuesday, U.S. District Judge Valerie Caproni in Manhattan also said investors may pursue some but not all antitrust and manipulation claims against Bank of Nova Scotia ("ScotiaBank") (BNS.TO) and HSBC Holdings Plc (HSBA.L).

Deutsche Bank AG (DBKGn.DE) settled related claims in April, and the investors plan soon to seek preliminary approval of a settlement, their lawyer Vincent Briganti said on Wednesday. Terms have not been disclosed.

MarketSlant has obtained documents regarding the London Gold Fix Scandal currently being litigated in the New York Southern District Court.

They include the Judge's initial findings in the class action suit pitting the LBMA and its member Banks vs. Entities and Individuals that trade Gold and allege they were victims of price manipulation and suppression from January 1, 2004 to June 30, 2013.

“The banking system in Sweden in pushing forcefully towards the direction of a cashless society and Tavex, as one of the largest wholesale suppliers of physical notes and investment metals is, in our view, being targeted by the merchant banks“. (emphasis added)

Despite the interruption to their business, Tavex has put an optimistic twist on the turn of events saying that they will set up a new payment system, describing the closed bank account as ‘temporary operational difficulties’ and an ‘inconvenience’ that will not have a lasting impact on their business or business model of delivering cash currency and physical investment metals to its clients.

JPMorgan Chase & Co on Wednesday won the dismissal of three private antitrust lawsuits, including from hedge fund manager Daniel Shak, accusing the largest U.S. bank of rigging a market for silver futures contracts traded on COMEX.

The lawsuits accused JPMorgan of having in late 2010 and early 2011 placed artificial bids onto the trading floor, harangued employees at metals market COMEX to obtain prices it wanted, and made misrepresentations to a committee that set settlement prices.
