ICE Benchmark Launches ICE Term SONIA Reference Rates LONDON (STL.News) Intercontinental Exchange, Inc. (NYSE:ICE), a leading operator of global exchanges and clearing houses and provider of mortgage technology, data and listings services, announces that ICE Benchmark Administration Limited (IBA) has today launched its ICE Term SONIA Reference Rates as a benchmark for use in financial instruments by licensees. The ICE Term SONIA Reference Rates (“ICE TSRR”) are designed to measure expected (i.e. forward-looking) SONIA rates over one, three, six and 12 month tenor periods, and are based on a Waterfall Methodology using eligible prices and volumes for specified SONIA-linked interest rate derivative products. The launch of the ICE TSRR as a benchmark follows the conclusion of a testing period which started on June 25, 2020, during which IBA made available an initial, beta versionof the ICE TSRR for information and testing purposes. Level 1 of the Waterfall uses tradeable bid and offer prices and volumes for eligible SONIA-linked interest rate swaps available on the central limit order books of platforms operated by BGC Partners, TP ICAP, and Tradition to generate the ICE TSRR.
