We continue to plan for a range of outcomes in relation to Brexit, including the UK leaving the EU without an implementation period on 29 March 2019. To prepare for this scenario, we have developed a new UK Benchmarks Register. The new Register will replace the ESMA Register for UK supervised users, and UK and third-country based benchmark administrators that want their benchmarks to be used in the UK.
