Back in August, I blogged about a report issued by the U.S. Senate Permanent Subcommittee on Investigations about how foreign banks, specifically large European banks, were helping wealthy Americans evade U.S. taxes. This week on Wednesday, the Justice Department, in conjunction with the Internal Revenue Service (IRS), announced the indicment of Raoul Weill, a senior executive at the Swiss banking giant UBS. Sharp BudgetBlog readers will remember that UBS was one of the European banks named in the Senate investigation released over the summer. Seems like things have come full circle for UBS. From the Justice Department press release: According to the criminal indictment, between 2002 and 2007, Weil oversaw the Swiss bank's cross-border private banking business that provided services to some 20,000 U.S. clients who reportedly concealed approximately $20 billion in assets from the IRS. Weil, who allegedly referred to this business as "toxic waste," mandated that Swiss bankers grow the cross-border business, despite knowing that this would cause bankers to violate U.S. law. According to the indictment, when given a choice to wind down, sell or spin off the cross-border business, Weil chose to continue the business because of its profitability. Between 2002 and 2007, the United States cross-border business generated between $200 million a year in revenue for the Swiss bank. Unfortunately, prosecutors may not be able to obtain the information necessary to convict Mr. Weill or expand their investigation to pursue U.S. clients who participated in tax evasion. Even if they are able to convict Mr. Weill, it's not assured that Switzerland would extradite him to the U.S. According to a report in the Wall Street Journal, the Swiss government has "firmly dug in its heels against the U.S. investigation, citing Swiss laws that generally prohibit banks from revealing the names of clients." The U.S. has demanded that the Swiss government step in to assure the investigation can continue, but doing so would likely hurt the prospects for Swiss banks, which have long served as a refuge for the rich and powerful in their attempts to horde assets. It is unclear how much trouble Mr. Weill has gotten himself into, but if convicted of the felony charge of conspiring to defraud the U.S. government, he could serve up to 5 years in jail. Somehow that doesn't seem to me like enough for stealing $1.2 billion from the American people. Jail time for Mr. Weill aside, the broader hope is that this case will open up Swiss banks and indeed the international banking industry generally, so we have a more honest, transparent, banking system that is held accountable to laws and regulations. That's the hope, but I'm not holding my breath.
