European Commission adopts Delegated Regulation on transparency requirements under MiFIR

On 13 July 2026, the European Commission adopted a delegated regulation setting out three sets of regulatory technical standards (RTS) relating to transparency requirements for trading venues and investment firms in respect of derivatives, package orders, and input and output data for the OTC derivatives consolidated tape under the Markets in Financial Instruments Regulation (MiFIR).

Background

The RTS are intended to reflect revisions to MiFIR made by Regulation (EU) 2024/791 (MiFIR II).

Summary

The delegated regulation amends the RTS in:

• Delegated Regulation (EU) 2017/583 in relation to transparency requirements for trading venues and investment firms in respect of derivatives.
• Delegated Regulation (EU) 2017/2194 in relation to package orders.
• Delegated Regulation (EU) 2025/1155 in relation to the input and output data of the OTC derivatives consolidated tape.

The delegated regulation also corrects errors in Article 12 of Delegated Regulation (EU) 2017/587.

Next steps

If neither the Council of the EU and the European Parliament object following scrutiny, the delegated regulation will be published in the Official Journal of the EU and come into force 20 days after publication. Articles 1, 2 and 3(1) to (5) will apply from 1 March 2027.
