The FTSE 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.
FTSE 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.
