LONDON, April 1 The global investigation into allegations of currency market manipulation intensified and spread its net on Tuesday, as regulators in Hong Kong and New Zealand said that they are investigating banks' conduct in the foreign exchange market.
Since the allegations first surfaced last year, some 30 traders have been placed on leave, suspended or fired by some of the world's biggest banks.
No individual or bank has been accused of wrongdoing and no evidence of wrongdoing has been found. All the banks involved say they are cooperating with the regulators.
Below is a timeline on what has engulfed the largely unregulated $5.3 trillion-a-day foreign exchange market, the world's biggest financial market.
