An investigation in Canada alleges that interest-rate rigging by staff working for British banks and financial institutions continued until at least June 2010, more than a year after Barclays' derivatives traders were found to have colluded in such practices.
An affidavit filed in Ontario's superior court by the criminal matters branch of Canada's competition bureau alleges that traders working for the British banks HSBC and RBS, as well as the broker Icap, conspired to fix rates relating to Japanese yen trades for personal gain. Traders from Deutsche Bank, JP Morgan and Citibank Canada are also said to have taken part. All contest the claims.

According to the affidavit, UBS has "provided the bureau with information that, during the material time, the participant banks, at times facilitated by the cash brokers, entered into agreements to submit artificially high or artificially low London interbank offered rate (Libor) submissions in order to impact the yen libor interest rates published by the British Bankers Association".
