On June 25, the European Securities and Market Authority (ESMA) published a letter (dated June 17) sent by Steven Maijoor, ESMA Chair, to Olivier Guersent, European Commission Director General for Financial Stability, Financial Services and Capital Markets Union (CMU), on the annual review required by Article 17 of Commission Delegated Regulation (EU) 2017/583 on transparency requirements for non-equity instruments (RTS 2).

The letter follows up a previous letter (dated January 16) sent to the Commission relating to the review reports on the MiFID II Directive and the Markets in Financial Instruments Regulation (Regulation 600/2014) (MiFIR). In that letter, ESMA raised the issue of carrying out the annual review of the operation of certain transparency requirements for bonds and derivatives, as required by Article 17 of RTS 2. A positive assessment by ESMA can lead to a legislative change subjecting more bonds, and larger trade sizes in bonds and derivatives, to real-time transparency.

ESMA considers that the outstanding uncertainties on the time and conditions of Brexit do not allow for an adequate assessment at this time. Including or excluding UK data from the assessment would have a fundamental impact on the results, and any decision whether to include UK data would depend on whether the UK is still a member of the EU at the time any legislative change would take effect. In addition, Brexit will likely affect liquidity in bond and derivative markets and the value of the assessment will be limited if it is carried out before these effects have materialized.
