A former UBS AG (NYSE:UBS) senior trader has been barred for life from working in the financial industry for manipulating financial data and falsifying reports.

Former UBS Trader Banned For Life

John Hughes, a senior trader on the bank’s synthetic equities desk in London, discovered a scheme on the trading desk whereby traders officially reported profits and losses were manipulated through a “slush fund of money” internally called the “umbrella,” the New York Times reports. This fund obfuscated $2.3 billion in trading losses by a junior trader, Kweku Adoboli, who is serving a seven year sentence in England.

UBS’ Hughes “felt a bit sick” but got well within a month

Hughes informed regulators that he “felt a bit sick” when he learned of the scheme, but within a month quickly found a level of comfort with the idea, chatting online with Adoboli on how and when to manipulate the financial reports.  Hughes said he knew he was “lying every day.”

Britain’s Financial Conduct Authority, which announced the action against Hughes today, appeared disturbed that when the slush fund and its role in falsifying reports was discovered that Hughes failed to become a whistleblower.  “Approved people should operate to the highest standards of integrity,” Tracey McDermott, the regulator’s director of enforcement and financial crime, was quoted as saying. “This means not only doing the right thing themselves but also challenging, and blowing the whistle on, those who are not. Hughes failed to do so with catastrophic consequences.”

Individual prosecution of bank executives in England

The individual criminal prosecution of bank executives comes after UBS AG (NYSE:UBS) was fined 29.7 million pounds, or about $50 million, in November 2012 for failing to detect or prevent the unauthorized trading.  In a case showing the slippery slope of fraud, while Hughes admitted being aware the “umbrella” slush fund was being used to manipulate financial reports, he claims not to be aware of the rouge trades on the desk.

Hughes was cooperative with regulators and did not hire a lawyer in his defense.  The issue could financially impact Hughes, who is said to have started an online betting web site, BetsofMates.com.  UBS employees fired for gross misconduct are not eligible for deferred compensation.
