A proposed class of investors has standing to sue some of the world’s largest financial institutions over their alleged manipulation of benchmark interest rates used to price financial derivatives in the yen currency market, a Manhattan-based appeals court said on Wednesday.

The ruling, from a three-judge panel of the U.S. Court of Appeals for the Second Circuit, revived a lawsuit against Citibank, HSBC Holdings, Merrill Lynch International and other banks accused of rigging the yen LIBOR and Euroyen TIBOR, which reflect the cost of borrowing Japanese yen.
