Market participants should act now to accelerate their transition away from LIBOR, Federal Reserve Vice Chair for Supervision Randal Quarles said.

Remarks: Speaking in Las Vegas, Quarles said the Dec. 31 end of LIBOR is “definitive and immovable” and will not be extended.

Quote: “To be ready for year-end, lenders will have to pick up the pace, and our examiners expect to see supervised institutions accelerate their use of alternative rates,” Quarles said.
