On 23 April 2018, the Bank of England (BoE) announced that it had implemented its reforms to the SONIA interest rate benchmark. Apart from the methodological changes, the publication time of SONIA has been moved, such that the SONIA rate for a given London business day is now published at 09:00 on the following London business day. The BoE will publish an assessment of its compliance with IOSCO’s Principles for Financial Benchmarks in the summer.
