LONDON (Reuters) - A former Barclays
Greek-born Stylianos Contogoulas told Southwark Crown Court on Wednesday that he had been instructed by his boss within days of joining the Barclays dollar desk in 2005 to tell a senior colleague the level he wanted Libor rates set at.
"It was done very openly and in a very normal way and gave the impression this was a regular, normal thing," Contogoulas said on his first day in the witness box.
Contogoulas, 44, is one of five former Barclays bankers charged with conspiracy to defraud by manipulating Libor, the London interbank offered rate, a benchmark for rates on around $450 trillion of financial contracts worldwide.
He and former colleagues Jonathan Mathew, Jay Merchant, Alex Pabon and Ryan Reich all deny dishonestly skewing rates - designed to reflect bank borrowing costs - to favor trading positions between June 2005 and September 2007.
As the second defendant to testify in the criminal trial, Contogoulas told the jury that he had been given no impression that asking for Libor rates was wrong or dishonest, that he had never had appropriate training, had not sought to conceal such requests and knew Barclays monitored communications.
In an email exchange on March 13, 2006, Contogoulas told senior London submitter Peter Johnson: "Remember when I retire and write a book about this business your name will be written in golden letters...and you'll have an open invitation to my bar in the Greek Islands he he"
Johnson responded: "I would prefer this not to be in any books!"
Contogoulas said during his testimony on Wednesday that this was all "just banter, not serious".
"Did anyone ever comment on your emailed requests to (Libor) submitters?" asked his lawyer John Ryder.
"No," said Contogoulas, adding that he spent just minutes each day doing so and received no personal advantage from doing so.
Johnson's lawyer declined to comment on Wednesday.
Contogoulas, who passed on Libor requests from more senior New York traders to submitters in London, said he stopped making verbal requests and started emailing them because U.S. colleagues might otherwise question whether he was passing their requests on.
Contogoulas's evidence follows that of Mathew, a former Libor submitter, who has told the court he had been taught by Johnson to adjust rates to suit traders and only realized this was wrong when interviewed by Barclays' lawyers in September 2009.
Mathew said he initially lied when U.S. authorities, who kickstarted a global Libor investigation in 2008, quizzed him in 2010 because he was afraid of his boss Johnson and of losing his job. He only told the truth when U.S. prosecutors offered him a non-prosecution agreement in 2011, he said.
The jury was told last week that Johnson, who had been charged alongside the other five defendants, pleaded guilty in 2014. The third Libor trial brought by the Serious Fraud Office (SFO) in London is scheduled to last 12 weeks.
