Use of UK data in ESMA databases and performance of MiFID II calculations in case of a no-deal Brexit on 31 October 2019 (ESMA70-155-7658)

The European Securities and Markets Authority’s (ESMA) statement on the publication of databases and IT-systems, including the update on 28 March 2019, informed the public of ESMA’s approach concerning the various transparency calculations in case of the United Kingdom (UK) leaving the European Union (EU) without a withdrawal agreement (no-deal Brexit). Following the European Council’s decision on 11 April the period under Article 50(3) TEU was extended resulting in a new potential no-deal Brexit date on 31 October 2019.

In case of a no-deal Brexit on 31 October 2019, the UK Financial Conduct Authority (FCA) will stop sending data to ESMA and will no longer have access to ESMA’s IT applications and databases. Starting from 1 November 2019 no new UK-related data will be received and processed by ESMA nor published on the ESMA website.

This updated statement informs stakeholders on ESMA’s approach to all ESMA IT applications and databases in case of a no-deal Brexit on 31 Octob
