LONDON—Four former Barclays traders have been sent to prison for manipulating a benchmark interest rate.
Judge Anthony Leonard said Thursday that the fraud committed by Jonathan James Mathew, Jay Vijay Merchant, Alex Pabon and Peter Johnson had hit the “integrity of the market.”
The four manipulated the London interbank offered rate, or Libor, between 2005 and 2007. Johnson pleaded guilty to conspiracy to defraud in October 2014. The others were found guilty by a jury last week.
