Transaction Reporting
Transaction reporting is the requirement for firms to report details of financial transactions to regulatory authorities. The purpose of transaction reporting is to;
- Promote transparency
- Monitor market activity
- Prevent financial crime
- Ensure compliance with regulatory requirements
Transaction Reporting is an obligation under MIFID II, and requires reports to be generated containing complete and accurate information on the types of instruments traded, when and how the instruments are traded, and by whom.

FCA and BoE Transaction and Post-trade Reporting Taskforce
The FCA and Bank of England (BoE) have invited firms to apply for membership of a new Transaction and Post-trade Reporting Taskforce, which will support the regulators’ work on harmonising transaction and post trade reporting requirements across UK MiFIR, UK EMIR and UK SFTR.
The taskforce will consist of three working groups covering policy, strategy and architecture and is intended to help shape longer term simplification and data alignment efforts. Firms with experience of transaction or post trade reporting are encouraged to consider getting involved.
In related reporting developments, the FCA published an update to the UK EMIR Validation Rules on 16 April 2026, reflecting changes to reconciliation requirements. The update includes:
- Setting a fixed reconciliation start date of 28 September 2026 for fields previously defined as two years from the start date of the reporting obligation
- Removing the requirement to reconcile the name of the underlying index field
- Aligning the validation rules for the Report Tracking Number with existing UK EMIR reporting guidance
Further details are available on the FCA’s UK EMIR reporting obligation webpage.
