Traders at some of the world’s biggest banks manipulated benchmark foreign-exchange (FX) rates used to set the value of trillions of dollars of investments, according to five dealers with knowledge of the practice.
Employees have been front-running client orders and rigging WM/Reuters rates by pushing through trades before and during the 60-second windows when the benchmarks are set, said the current and former traders, who requested anonymity because the practice is controversial. Dealers colluded with counterparts to boost chances of moving the rates, said two of the people, who worked in the industry for a total of more than 20 years.
The WM/Reuters rates data is collected and distributed by World Markets Co., a unit of Boston-based State Street Corp. (STT), and Thomson Reuters Corp. (TRI) Bloomberg LP, the parent company of Bloomberg News, competes with New York-based Thomson Reuters in providing news and information, as well as currency-trading systems and pricing data. Bloomberg LP also distributes the WM/Reuters rates on Bloomberg terminals.
One trader with more than a decade of experience said that if he received an order at 3:30 p.m. to sell 1 billion euros (US$1.3 billion) in exchange for Swiss francs at the 4 p.m. fix, he would have two objectives: to sell his own euros at the highest price and also to move the rate lower so that at 4 p.m. he could buy the currency from his client at a lower price.
