LONDON—A British judge sentenced a former Citibank and UBS trader to 14 years in prison Monday after a jury found him guilty of masterminding the manipulation of a key interest rate, the London Interbank Lending Rate, or Libor.
Judge Jeremy Cooke sentenced 35-year-old Tom Hayes, who specialized in products pegged to yen-denominated Libor, after jurors found him guilty of manipulating the rate from 2006 to 2010. He was charged with conspiring with other traders — but he says he was made a scapegoat for a common practice.
