Global regulators imposed penalties totalling $3.4 billion on JPMorgan, HSBC, RBS, UBS and Citigroup.

Royal Bank of Scotland and JP Morgan were also fined for attempting to manipulate foreign exchange benchmarks in a year-long probe that has put the largely unregulated $5 trillion-a-day market on a tighter leash, with dozens of dealers suspended or fired.

JP Morgan's Frankfurt-listed shares dipped 1.2 percent. Royal Bank of Scotland's Frankfurt-listed shares fell declined by 1.3 percent while HSBC's Frankfurt-listed shares retreated by 1.4 percent.

"Now that the fines have been done and dusted, it may not be taken too badly by the market," said Terry Torrison, managing director at Monaco-based McLaren Securities.
