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. 

Refinitiv Term SONIA is now live. 

Licensed users can use the benchmark as a reference rate in financial instruments, financial contracts, and valuation and pricing activities.


The Refinitiv Term SONIA benchmark is a forward-looking, risk-free reference rate available in 1-month, 3-month, 6-month and 12-month tenors denominated in sterling and designed to be an alternative to GBP LIBOR.

On 5 March 2021 the FCA confirmed that all GBP LIBOR settings would cease or no longer be representative.  That means market participants must seek alternative rates and in many cases a Term SONIA Reference Rate will be suitable.

Refinitiv Term SONIA is published to 4 decimal places, thereby ensuring consistency with the Bank of England’s SONIA benchmark.

Our rate is viewed by hundreds of clients worldwide.

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.

Refinitiv Term SONIA is production ready. A forward-looking alternative which, tested at the height of Covid-19 volatility, is proven to deliver even in extreme market conditions.
