Regulators globally are broadening the spread of their investigations into rate setting that began with manipulation of LIBOR. As they explore how rates were set for pricing on foreign exchange derivatives, UBS and Royal Bank of Scotland Group have suspended traders in Singapore.
Bloomberg reported late Sunday that UBS suspended at least two foreign exchange traders and RBS one as investigations widen to include rates other than LIBOR.
Ken Choy, a director in the emerging markets foreign exchange trading unit at RBS, was identified by a source as the trader suspended by that bank. The two put on leave at UBS, said a person with knowledge of the matter, have run afoul of an internal probe into manipulation of nondeliverable forwards. These are derivatives used by traders to speculate on the movement of currencies subject to domestic foreign exchange restrictions.
