Barclays Plc (NYSE ADR: BCS) was fined $43.8 million today (Friday) by a U.K. regulatory agency as part of a gold price fix episode back in 2012 .
A trader abused Barclays' role as one of the big banks that participates in a twice-daily conference call to set gold prices. He manipulated the price of gold lower to avoid taking a big loss to a customer who had (correctly) bet gold prices would rise.
