NEW YORK: Twenty-two financial companies that have served as primary dealers of U.S. Treasury securities were sued in federal court on Thursday, in what was described as the first nationwide class action alleging a conspiracy to manipulate Treasury auctions that harmed both investors and borrowers.
The State-Boston Retirement System, the pension fund for Boston public employees, accused Bank of America Corp's
According to the pension fund's complaint, filed in U.S. District Court in New York, the banks used chat rooms, instant messages and other means to swap confidential customer information and coordinate trading strategies in the roughly $12.5 trillion Treasury market.
This enabled the banks to inflate prices on Treasuries they sold to investors in the pre-auction "when issued" market, and deflate prices when they bought Treasuries to cover their pre-auction sales, violating antitrust laws, according to the complaint.
Primary dealers are the banks authorized to transact directly with the Federal Reserve. They are big players in Treasury bond auctions and act as market makers in the secondary market.
The pension fund said its "expert economists" observed wide gaps between when-issued and auction prices around December 2012, but that these gaps narrowed significantly as the U.S. Department of Justice and other regulators began probing alleged manipulation of the London interbank offered rate, a benchmark used to set interest rates for trillions of dollars worth of loans around the world.
"The only plausible explanation for the sharp break," the fund said, "is that defendants felt the heat of the DOJ's ongoing investigation into Libor, and ceased their efforts to manipulate the Treasury securities market because defendants' Treasury traders feared that they too would be prosecuted."
Media reports last month said the Justice Department was also investigating possible collusion in Treasury auctions.
"The scheme harmed private investors who paid too much for Treasuries, and it harmed municipalities and corporations because the rates they paid on their own debt were also inflated by the manipulation," Michael Stocker, a partner at Labaton Sucharow, which represents State-Boston, said in an interview. "Even a small manipulation in Treasury rates can result in enormous consequences."
The lawsuit seeks class-action status on behalf of investors in Treasury securities, including futures and options, from 2007 to 2012, and unspecified triple damages.
Spokespeople for Bank of America, Citigroup, Credit Suisse, Deutsche Bank, Goldman, HSBC and UBS declined to comment. Other banks had no immediate comment or were not reached.
