What is MAR 14 Transaction Reporting?

MAR 14 sets out the FCA’s regulatory framework for transaction reporting, establishing the requirements firms must follow when reporting transactions in financial instruments. It supports the FCA’s ability to monitor market activity, identify potential market abuse and maintain the integrity of UK financial markets.

About MAR 14 Transaction Reporting

Transaction reporting has been a core part of the UK’s market oversight framework since the MiFIR transaction reporting requirements were implemented in 2018. Under the current regime, firms report transactions in reportable financial instruments under Article 26 of UK MiFIR, giving the FCA detailed data to monitor financial markets, detect and investigate potential market abuse, and support its supervisory activities.

In August 2026, the FCA published Policy Statement PS26/15, Improving the UK Transaction Reporting Regime, setting out a significant reform of this framework. The reforms are intended to create a more proportionate and streamlined UK transaction reporting regime by simplifying reporting obligations, removing duplicative or low value requirements and improving consistency in how key data fields are populated.

As part of this reform, the FCA is introducing MAR 14: Transaction Reporting, a new chapter of the FCA Handbook setting out the rules and requirements for reporting transactions in reportable financial instruments. MAR 14 will form part of the new UK transaction reporting framework when the revised regime takes effect on 3 April 2028.

Until then, PS26/15 establishes an implementation period during which the FCA is taking a flexible supervisory approach in specified areas. From 3 August 2026, firms can benefit early from certain reforms, including the reduced three year default back reporting period and selected changes to reporting scope and field requirements, while continuing to prepare their systems, controls and reporting processes for the full MAR 14 framework.
