What is MiFID II Post-Trade Transparency Reporting?
First introduced in 2007 and revised in 2018, the EU and UK's Markets in Financial Instruments Directive (MiFID II) aims to enhance market resilience, transparency, and investor protection. Under MiFID II Post-Trade Transparency Reporting, investment firms must provide complete and accurate trade details to an Approved Publication Arrangement (APA) for publication.
About MiFIDII Post-Trade Transparency
To promote market resilience and transparency, MiFID II outlines a series of Articles and technical standards which must be adhered to; these apply to all EU trading venues (RM, MTF, OTF), SIs and UK equivalents.
Post-Trade Transparency Reporting is outlined in RTS 1 and RTS 2 of MiFIR:
- Near real-time market reporting via the Financial Information eXchange (FIX)
- Reports to be sent to the APA within 1-min for equity (and equity-like products) and within 5-min for non-equity products
- 20+ Required fields such as Trading Date and Time, ISIN, Price, Venue of Execution and more
These reports are then anonymised, aggregated and published by the APA with the ultimate goal being to promote transparency between market participants.
The regulation is the responsibility of the European Securities and Markets Authority (ESMA) and is enforced in the UK by the Financial Conduct Authority (FCA). Post-Brexit, since 2021, the two regulators are increasingly divergent, releasing a series of consultation papers detailing the region-specific differences in reporting.

FAQs: MiFID II Post-Trade Transparency
Post-Trade Transparency under MiFID II mandates that certain key details of securities transactions are made public immediately after the trade is executed. The purpose of this is to increase transparency for market participants, as well as to enable the relevant competent authority to monitor systemic risk and market abuse. Post-trade reporting also ensures the data is available on a non-discriminatory basis, by ensuring the data is provided in a standardised format.
Reports must be submitted to an Approved Publication Arrangement (APA) and include comprehensive details such as the financial instrument, the price, the quantity, and the execution time of the trade. This information is then aggregated and published to ensure accessibility and transparency for all.
All market participants, including investment firms, trading venues, sell-side entities, and systematic internalisers are required to report post-trade transaction details. This applies to any financial instrument traded on EU-regulated markets, multilateral trading facilities, organized trading facilities, and certain over-the-counter transactions.
An APA plays a critical role in MiFID II compliance by collecting and disseminating trade reports on behalf of investment firms. They ensure that trade information is standardised and published in a manner that is accessible and useful to the public and market participants. APAs do this to enhance market transparency and aid regulatory oversight.
Enhanced post-trade transparency helps increase market integrity by providing investors with timely and accurate trade data, fostering better market surveillance, and promoting more informed investment decisions, thereby protecting investor interests and improving market confidence.
A post-trade transparency report under MiFID II must include the type of financial instrument, the quantity traded, the execution time, the price, and the identity of the trading venue. This detailed reporting ensures that all market participants have a clear and comprehensive view of trading activity, fostering greater market transparency.
