NEW YORK (IFR/Reuters) – A class action lawsuit, filed Wednesday, accuses 10 of Wall Street’s biggest banks and two trading platforms of conspiring to limit competition in the $320 trillion market for interest rate swaps. The class action lawsuit, filed in U.S. District Court in Manhattan, accuses Goldman Sachs, Bank of America Merrill Lynch, JPMorgan Chase, Citigroup, Credit Suisse, Barclays, BNP Paribas, UBS, Deutsche Bank, and the Royal Bank of Scotland of colluding to prevent the trading of interest rate swaps on electronic exchanges, like the ones on which stocks are traded.
