(AP) WASHINGTON - WASHINGTON (AP) â€” The Federal Deposit Insurance Corp. has sued 16 big banks that set a key global interest rate, accusing them of fraud and conspiring to keep the rate low to denrich themselves.
The banks, which include Bank of America Corp., Citigroup Inc. and JPMorgan Chase & Co. in the U.S., are among the world's largest.
The FDIC says it is seeking to recover losses suffered from the rate manipulation by 10 U.S. banks that failed during the financial crisis and were taken over by the agency. The civil lawsuit was filed Friday in federal court in Manhattan.
The banks rigged the London interbank offered rate, or LIBOR, from August 2007 to at least mid-2011, the FDIC alleged. The LIBOR affects trillions of dollars in contracts around the world, including mortgages, bonds and consumer loans. A British banking trade group sets the LIBOR every morning after the 16 international banks submit estimates of what it costs them to borrow. The FDIC also sued that trade group, the British Bankers' Association.
By submitting false estimates of their borrowing costs used to calculate LIBOR, the 16 banks "fraudulently and collusively suppressed (the LIBOR rate), and they did so to their advantage," the FDIC said in the suit.
Citigroup spokeswoman Danielle Romero-Apsilos, Bank of America spokesman Lawrence Grayson and JPMorgan spokesman Brian Marchiony declined to comment.
Four of the banks â€” Britain's Barclays and Royal Bank of Scotland, Switzerland's biggest bank UBS and Rabobank of the Netherlands â€” have previously paid a total of about $3.6 billion to settle U.S. and European regulators' charges of rigging the LIBOR. The banks signed agreements with the U.S. Justice Department that allow them to avoid criminal prosecution if they meet certain conditions.
The process of setting the LIBOR came under scrutiny after Barclays admitted in June 2012 that it had submitted false information to keep the rate low.
A number of U.S. cities and municipal agencies also have filed suits against banks that set the LIBOR rate. They are seeking damages for losses suffered as a result of an artificially low rate. Local governments hold bonds and other investments whose value is pegged to LIBOR.
In addition, government-controlled mortgage giants Fannie Mae and Freddie Mac have brought similar suits against many of the banks.
Under a change announced last July, the London-based company that owns the New York Stock Exchange, NYSE Euronext, will take over supervising the setting of LIBOR from the British Bankers' Association. The changeover is scheduled to be completed by early next year.
The FDIC asserted in its suit that the banks' misconduct in setting LIBOR caused "substantial losses" to the 10 U.S. banks that failed. The amount wasn't specified. The agency is seeking both economic and punitive damages, to be determined by the court.
The other banks named in the suit are Switzerland's Credit Suisse, Germany's Deutsche Bank and Portigon, British banks HSBC and Lloyds, France's Societe Generale, Japan's Norinchukin Bank and Bank of Tokyo-Mitsubishi, and Royal Bank of Canada.
