LIBOR transition

Refinitiv Term SONIA

Clients around the world trust us to provide benchmarks such as WMR and CDOR with transparency and integrity. Now you can trust us to do the same with Refinitiv Term SONIA. 


The Refinitiv Term SONIA prototype is a forward-looking, risk-free reference rate available in one-month, three-month,six-month and twelve-month tenors denominated in sterling and designed to be an alternative to LIBOR.

The Working Group on Sterling Risk-Free Reference Rates recommends that all new issuance of sterling LIBOR-referencing loan products, which expire after the end of 2021, should cease by the end of Q1 2021. And after the year-end 2021, the Financial Conduct Authority, which regulates the LIBOR benchmark administrator, will no longer compel banks to submit to LIBOR, creating a strong possibility of an imminent cessation. That means market participants must rapidly seek alternative rates and in many cases a Term SONIA Reference Rate will be suitable.

Why Refinitiv?

Regarded around the world as a leading provider of financial benchmarks, we are already trusted by thousands of institutions to provide rates such as WMR and CDOR with transparency and integrity. At Refinitiv we have leveraged our many years’ experience administering regulated benchmarks to create the Term SONIA Reference Rate prototype.
