Financial Conduct Authority says former trader at bank exploited systems to profit at the expense of a customer
Barclays has been fined £26m by the City regulator over failings related to setting the price of gold.
The Financial Conduct Authority (FCA) said it had fined the bank “for failing to adequately manage conflicts of interest between itself and its customers as well as systems and controls failings” over nine years between 2004 and 2013.
