(NYSE:ICE), a leading global provider of data, technology and market infrastructure, today announced that ICE Benchmark Administration Limited (“IBA”) has launched ICE SONIA Indexes for use by licensees, following a successful testing period. ICE SONIA Indexes have been developed to support the needs of the UK lending market as it transitions to SONIA, and are designed to provide a simple method for parties to calculate SONIA compound interest between any two dates and agree on their associated interest accruals. The Indexes expand IBA’s SONIA-based solutions offering and are available to licensees alongside ICE Term SONIA Reference Rates (ICE TSRR). ICE TSRR were launched as a benchmark in January 2021 to provide businesses, borrowers and lenders with a forward-looking, term SONIA benchmark to provide certainty when calculating their interest expenses and other contractual payments in advance.
