Deutsche Bank AG (DBKGn.DE) agreed to settle U.S. lawsuits accusing it of conspiring with other banks to manipulate gold and silver prices at investors' expense, court papers show.

The plaintiffs accused Deutsche Bank of conspiring with Bank of Nova Scotia (BNS.TO), Barclays Plc (BARC.L), HSBC Holdings Plc (HSBA.L) and Societe Generale (SOGN.PA) to manipulate prices of gold, gold futures and options, and gold derivatives through twice-a-day meetings to set the so-called London Gold Fixing.

They also accused Deutsche Bank, HSBC and ScotiaBank of a similar conspiracy to manipulate silver prices by rigging the daily Silver Fix.
