Peter Johnson and Jonathan Mathew, who both left Barclays in September 2012, and Stylianos Contogoulas, who worked at the bank for just under four years before leaving in April 2006, have been charged by the SFO with conspiracy to defraud between June 1, 2005 and August 31, 2007.
The charges were announced by the SFO and mean that six people have now been charged in relation to the manipulation of the LIBOR rate.
The SFO is continuing to investigate the manipulation of benchmark interest rates and further charges are expected.
