HSBC, Goldman Rigged Metals' Prices for Years: Suit

Standard Bank Group Ltd. and a metals unit of BASF SE, the world's largest chemical company, were also sued. The four companies used inside information about client purchases and sale orders to profit from price movements for the metals used in products ranging from jewelry to cars, according to a complaint filed yesterday in Manhattan federal court.

The lawsuit by Modern Settings LLC, a jeweler that buys precious metals and derivatives set on their prices, claims the companies "were privy to and shared confidential, non-public information about client purchase and sale orders that allowed them to glean information about the direction" of prices.
