Oversight of Libor will be handed to the U.K.'s financial regulator, and dozens of the currencies and maturities that make up the benchmark axed, under proposals designed to revive confidence in a rate tarnished by scandal.

The British Bankers' Association should be stripped of the responsibility for managing the rate and other organizations invited to replace it, Financial Services Authority Managing Director Martin Wheatley said in London today. More than 100 Libor rates tied to currencies and maturities where there isn't enough trading data to set them properly should be scrapped, and a code of conduct introduced for how lenders contribute to the benchmark backed by criminal penalties, he added.

“Governance of Libor has completely failed,” Wheatley said as he unveiled a report on the future of Libor. “This problem has been exacerbated by a lack of regulation and a comprehensive mechanism to punish those who manipulate the system.”
