The fines would be paid to settle allegations of attempted manipulation of foreign exchange trading. This follows an international investigation by U.S. and U.K. regulators into the $5.3 trillion-a-day forex trading market. The probes stem from claims that foreign exchange benchmarks and a key interbank interest rate known as the London Interbank Offered Rate (Libor) were rigged by traders from 2005 onwards.
