Prosecutors, regulators close to making Libor arrests Defense lawyers, some of whom represent individuals under suspicion, said prosecutors have indicated that they plan to begin making arrests and filing criminal charges in the next few weeks. In long-running financial investigations it is not uncommon for prosecutors to contact defense lawyers for individuals before filing charges to offer them a chance to cooperate or take a plea, the lawyers said. The prospect of charges and arrests of individuals means that prosecutors are getting a fuller picture of how traders at major banks allegedly sought to influence the London Interbank Offered Rate, or Libor, and other global rates that underpin hundreds of trillions of dollars in assets. The criminal charges would come alongside efforts by regulators to punish major banks with fines. "The individual criminal charges have no impact on the regulatory moves against the banks," said a European source familiar with the matter. But banks are hoping that at least regulators will see that the scandal was mainly due to individual misbehavior of a gang of traders. In Europe, financial regulators are focusing on a ring of traders from several European banks who allegedly sought to rig benchmark interest rates such as Libor, said the European source familiar with the investigation in Europe. The source, who did not want to be identified because the investigation is ongoing, said regulators are checking through e-mails among a group of traders and believe they are now close to piecing together a picture of how they allegedly conspired to make money by manipulating the rates. The rates are set daily based on an average of estimates supplied by a panel of banks. There are also probes in Europe concerning Euribor, the Euro Interbank Offered Rate. It is not clear what individuals and banks federal prosecutors are most focused on. A Justice Department lawyer overseeing the investigation did not respond to a request for comment. Reuters previously reported that more than a dozen current and former employees of several large banks are under investigation, including Barclays Plc, UBS and Citigroup, and have hired defense lawyers over the past year as a federal grand jury in Washington continues to gather evidence. The activity in the Libor investigation, which has been going on for three years, has quickened since Barclays agreed last month to pay $453 million in fines and penalties to settle allegations with regulators and prosecutors that some of its employees tried to manipulate key interest rates from 2005 through 2009. Barclays, which signed a non-prosecution agreement with U.S. prosecutors, is the first major bank to reach a settlement in the investigation, which also is looking at the activities of employees at HSBC, Deutsche Bank and other major banks.
