Barclays, JPMorgan, Citigroup help US broaden currency probe

Washington

BARCLAYS plc didn't close the book on allegations of currency rigging with last year's guilty plea: since then, the bank has reviewed more than 2.4 million documents and 100,000 audio calls about its foreign-exchange practices and interviewed dozens of current and ex-employees.

Now the US government is using information from Barclays and two other banks, JPMorgan Chase & Co and Citigroup Inc, to broaden its long-running investigation into the manipulation of foreign-currency markets.
