In a decision made public on Wednesday, U.S. District Judge Edgardo Ramos in Manhattan said the investors failed to show they were injured by conducting any specific transactions in U.S. dollar-denominated supranational, sub-sovereign and agency bonds that were tainted by the alleged collusion.

Investors led by the Iron Workers Pension Plan of Western Pennsylvania and the Sheet Metal Workers Pension Plan of Northern California said the banks used chatrooms and other means to share pricing data and coordinate trading to boost profit, infecting "each and every" transaction.

The defendants included Barclays Plc, BNP Paribas, Citigroup Inc, Credit Agricole SA, Credit Suisse Group, HSBC Holdings Plc, Nomura Holdings Inc, Royal Bank of Canada and Toronto-Dominion Bank.

Dan Brockett, a lawyer for the investors, said his clients plan to amend their complaint.

He also said Ramos' decision, which is dated Aug. 24, does not affect Deutsche Bank and Bank of America Co respective $48.5 million and $17 million settlements in the case in August 2017.

Ramos preliminarily approved those settlements in March.

The federal court in Manhattan is home to a wide array of private litigation accusing banks of conspiring to rig various financial markets, interest rate benchmarks and commodities.

The case is In re: SSA Bonds Antitrust Litigation, U.S. District Court, Southern District of New York, No. 16-03711.
