Helping you plan for the LIBOR transition
The London Interbank Offered Rate interest benchmark is ending
On 5 March 2021 the Financial Conduct Authority confirmed that all London Interbank Offered Rate (LIBOR) settings will either cease to be provided by any administrator or no longer be representative:
- immediately after 31 December 2021, in the case of all sterling, euro, Swiss Franc and Japanese Yen settings, and the 1-week and 2-month US Dollar settings; and
- immediately after 30 June 2023, in the case of the remaining US Dollar settings

In line with the Working Group on Sterling Risk-Free Reference Rates (Sterling RFRWG) recommended milestones, NatWest Group (NWG) no longer offer new GBP LIBOR-linked loans from the end of March 2021. This milestone applies to all GBP-linked bilateral and syndicated new lending, including multicurrency facilities, as well as the amendment or refinancing of existing facilities which from 1 April 2021 must instead be linked to SONIA or an alternative Risk-Free Reference rate.
The Sterling RFRWG has issued a Q&A document and a Best Practice Guide to assist market participants in transitioning away from the use of LIBOR in the GBP loan market in accordance with the recommended milestones.
NWG is a member of the Sterling RFRWG and Chair of the Loan Enablers Task Force established to help facilitate the launch and adoption of SONIA loan products in the GBP market. NWG fully supports the Sterling RFRWG milestones and is actively working to help customers navigate away from LIBOR for both new and existing lending.
What's changing and why
SONIA - An overview
LIBOR is a forward-looking term rate. However Sterling Over Night Indexed Average (SONIA) is a backward-looking, overnight rate based on actual transactions that have taken place the day before.
SONIA is an overnight rate, set in arrears and based on actual transactions in overnight indexed swaps for unsecured transactions in the Sterling market. SONIA is a risk-free rate meaning no bank credit risk is included.
SONIA is expected to replace GBP LIBOR across global financial markets by the end of 2021.
How is SONIA calculated?
Each London business day the SONIA fixing is calculated as the weighted average rate of all unsecured overnight sterling transactions brokered in London by Wholesale Markets Brokers’ Association (WMBA) members between 12am and 3.15pm London time in a minimum deal size of £25m.
Is SONIA a Term Rate?
SONIA is an overnight rate, not a term rate.
A term rate provides borrowers with a known interest rate for the period of borrowing and therefore provides up-front certainty of the amount of interest due at the end of the interest period. Some borrowers may find this helpful for their cashflow forecast.
SONIA is an overnight rate, based on actual market rates and reset on a daily basis in arrears; this removes any expectation of future events inherent in a forward-looking term rate.
Can I calculate a compounded rate for SONIA?
Our NatWest Group colleagues in NatWest Markets have shared developed a simple ‘calculator’ to help clients get comfortable with what a SONIA rate means in practice. This calculator shows you what the annualise compounded interest rate is for any defned period since the Bank of England started publishing the SONIA interest rate benchmark.
