An ex-J.P. Morgan Chase trader has admitted to manipulating the U.S. markets of an array of precious metals for about seven years -- and he has implicated his supervisors at the bank.

John Edmonds, 36, pleaded guilty to one count of commodities fraud and one count each of conspiracy to commit wire fraud, price manipulation and spoofing, according to a Tuesday release from the U.S. Department of Justice. Edmonds spent 13 years at New York-based J.P. Morgan until leaving last year, according to his LinkedIn account.

As part of his plea, Edmonds said that from 2009 through 2015 he conspired with other J.P. Morgan traders to manipulate the prices of gold, silver, platinum and palladium futures contracts on exchanges run by the CME Group. He and others routinely placed orders that were quickly cancelled before the trades were executed, a price-distorting practice known as spoofing.
