Bank of America Corp, Citigroup and Credit Suisse Group AG were among 16 of the world’s biggest banks sued by the US Federal Deposit Insurance Corp for allegedly manipulating the London interbank offered rate (Libor) from 2007 to 2011.

The FDIC, acting as receiver for 38 failed banks including Washington Mutual Bank, IndyMac Bank FSB and Colonial Bank, claimed that institutions sitting on the US dollar Libor panel “fraudulently and collusively suppressed” the rate. Also named in the suit, filed yesterday in Manhattan federal court, is the British Bankers Association, an industry group that oversaw Libor.

Regulators around the world have been probing whether firms colluded to manipulate interest-rate benchmarks including Libor, which affects more than $300tn of securities worldwide. Financial institutions have paid about $6bn so far to resolve criminal and civil claims in the US and Europe that they manipulated benchmark interest rates.

The cost for global investment banks could climb to $46bn, analysts at KBW, a unit of Stifel Financial Corp, said in a report last year. JPMorgan Chase & Co and HSBC Holdings Plc may face a European Union complaint as soon as next month from the bloc’s antitrust chief.

The failed banks “reasonably expected that accurate representations of competitive market forces, and not fraudulent conduct or collusion,” would determine the benchmark, the FDIC said in its complaint.

Charlotte, North Carolina-based Bank of America dropped 36 cents to $16.80; New York-based Citigroup declined 45 cents to $46.88; and Zurich-based Credit Suisse’s American depositary receipts fell 77 cents to $30.25 in New York trading.

Barclays, Rabobank, UBS AG and Royal Bank of Scotland have resolved Libor-related investigations.

Investigators claim the banks altered submissions used to set the benchmark to profit from bets on interest-rate derivatives or to make the lenders’ finances appear healthier.

In addition to Bank of America, Citigroup and Credit Suisse, the banks sued yesterday are JPMorgan Chase, HSBC, Barclays, Rabobank, UBS, Royal Bank of Scotland, Deutsche Bank AG, Lloyds Banking Group, Societe Generale SA, Norinchukin Bank, Royal Bank of Canada, Bank of Tokyo-Mitsubishi UFJ and WestLB AG.

In its complaint, the FDIC claimed the fixed rates caused the failed banks to pay higher prices for Libor-based financial products and to get lower interest payments from the defendants and others.

Many of the failed banks sought out Libor-based derivatives as protections, not to seek capital gains, said Robert DeYoung, a University of Kansas professor who is a research fellow at the FDIC.

“There’s an awful lot of proof that the FDIC has to come up with to make their case,” DeYoung said.

The FDIC, which insures bank deposits, has previously sued big, global banks for misrepresenting securities based on mortgages and harming banks that went on to fail.

The suit filed is “very consistent with the cases they’ve brought on mortgage-backed securities,” said Michael Krimminger, a former FDIC general counsel who represents banks at Cleary Gottlieb Steen & Hamilton LLP in Washington. The difference is in the complexity of proving harm, raising “much more difficult questions of proof for the FDIC,” he said.

The FDIC claims breach of contract on behalf of 10 of the failed banks, including Washington Mutual and IndyMac, which entered into Libor-based interest-rate swap contracts with banks that are named as defendants.

The FDIC alleges the banks committed fraud and violated US antitrust laws in fixing the US dollar Libor benchmark. It’s seeking unspecified damages on behalf of the failed banks, including punitive damages and triple damages for price-fixing.

Drew Benson, a spokesman for Credit Suisse; Lawrence Grayson, a spokesman for Bank of America; Mark Costiglio, a Citigroup spokesman; Yuji Okumura, a Bank of Tokyo-Mitsubishi UFJ spokesman; and Brian Marchiony, a JPMorgan Chase spokesman, declined to comment on the suit. FDIC spokesman David Barr also declined to comment.

Roelina Bolding, a spokeswoman for Utrecht, Netherlands- based Rabobank, didn’t immediately respond to e-mail messages seeking comment yesterday after business hours.

HSBC spokesman Rob Sherman; Gregg Rosenberg, a UBS spokesman; Barclays spokesman Mark Lane; and Linda Harper, a Royal Bank of Scotland spokeswoman, didn’t immediately return messages seeking comment yesterday after business hours.

The case is Federal Deposit Insurance Corp v. Bank of America Corp, 14-cv-01757, US District Court, Southern District of New York (Manhattan).
