The $1.6bn billion figure would be more than three times the $469m that Barclays agreed to pay last June to settle allegations that its employees conspired to manipulate the London interbank offered rate, which is used in bank borrowing.
As part of the case, U.S. prosecutors are planning to file charges against multiple bankers associated with UBS’s rigging of Tokyo interbank lending rates, according to another person with knowledge of the matter. The charges would be the first brought by the Department of Justice against individuals alleged to have manipulated Libor and comparable lending rates in Europe and Japan.
The prosecution is slated to begin in tandem with an announcement that UBS Securities Japan Ltd., the Japanese unit of the Zurich-based bank, would plead guilty to manipulating Japanese interest rates starting in 2007, said the person, who asked not to be named because the matter is private.
And Reuters reports that citing unnamed sources, Tages-Anzeiger daily said the bank would admit 36 traders around the globe manipulated yen Libor between 2005 and 2010. A UBS spokesman declined to comment.
