Morgan Stanley's Reason for FX Trader's Exit Found 'Defamatory'; Finra panel rules language in regulatory filing should change; Head of FX options Thiago Melzer left Morgan Stanley last year Donal Griffin – Bloomberg The reason Morgan Stanley gave for the dismissal of senior currencies trader Thiago Melzer was defamatory, an arbitration panel found. A Financial Industry Regulatory Authority panel of independent arbitrators said that the reason set out on a regulatory filing for Melzer's exit should be "deleted in its entirety." Instead, it should show that the bank terminated him because of its "perception of his supervisory actions which were not related to any securities, customer interaction or sales practices," according to a copy of the September judgment obtained by Bloomberg. /jlne.ws/3y3xLHB
