Three former Barclays traders have been found guilty by a London jury of conspiring to fraudulently manipulate global benchmark interest rates in a stark warning to junior bankers and a major victory for Britain’s Serious Fraud Office (SFO).

The jury in the London trial of five former Barclays traders charged with conspiracy to manipulate global Libor interest rates yesterday retired to consider its verdict after hearing more than 10 weeks of evidence.
