Further to a November 2022 consultation, the FCA has decided to use its powers under UK Benchmarks Regulation (UK BMR) to require ICE Benchmark Administration (IBA) to continue publication of 1-, 3- and 6-month US dollar LIBOR settings using an unrepresentative synthetic methodology. The FCA will require IBA to publish these synthetic US dollar LIBOR settings for a temporary period after 30 June 2023, following the end of the US dollar LIBOR bank panel, and intends for them to cease entirely on 30 September 2024.
From 1 July 2023, all new use of synthetic US dollar LIBOR by UK supervised entities will be prohibited under the UK BMR, which the FCA notes will override the exemptions to the prohibition on the new use of US dollar LIBOR imposed by the FCA on 1 January 2022. The FCA will allow the use of the 1-, 3- and 6-month synthetic US dollar LIBOR settings by supervised entities in all legacy contracts, except for cleared derivatives.
