Transaction Reporting Obligations.
Transaction Reporting Obligations Under MiFID II
1. Definition and Purpose
Transaction reporting under MiFID II is the requirement for investment firms to report details of every transaction in financial instruments to their National Competent Authorities (NCAs) in order to:
Ensure market transparency
Assist regulators in detecting market abuse
Support market integrity and investor protection
Scope:
Applies to all investment firms and trading venues in the EU executing transactions in financial instruments, including shares, bonds, derivatives, and ETFs.
Includes retail and professional clients, as well as transactions executed for the firm’s own account.
2. Key Requirements Under MiFID II
Reportable Transactions
All transactions executed on a trading venue or OTC, if the financial instrument is traded on an EU venue.
Includes orders executed on behalf of clients or for the firm’s proprietary account.
Content of Reports
Each report must include:
Identity of the firm executing the transaction
Client classification (retail, professional, eligible counterparty)
Instrument identifier (ISIN)
Price and volume

Accuracy and Integrity
Firms are responsible for ensuring that reports are complete, accurate, and timely.
Failures may constitute a breach of MiFID II and lead to penalties.
Third-Party Delegation
Firms may delegate reporting to a third party, but remain fully responsible for accuracy and timeliness.

Case 4: Commission v. Italy (CJEU, 2011)
Facts: Italy delayed transposing MiFID I/II reporting and transparency requirements.
Issue: National authority’s duty to enforce reporting obligations for investment firms.

5. Key Lessons from These Cases
Accuracy and Timeliness: T+1 reporting is mandatory, and errors attract fines.
Algorithmic and High-Frequency Trading: Increases risk of misreporting; requires robust systems.
Firm Responsibility: Delegation does not relieve the firm of liability.
National Accountability: Member States must ensure firms comply.
Retail Transactions Are Included: Not limited to professional or institutional trades.
Regulatory Oversight: Accurate reporting supports market surveillance, transparency, and detection of abuse.
6. Conclusion
Transaction reporting under MiFID II is a cornerstone of market transparency, investor protection, and regulatory oversight. Firms must:
Report all transactions accurately and on time
Ensure data integrity, compliance with reporting templates, and T+1 deadlines
Monitor internal systems, including algorithmic trading
Maintain documentation for regulatory audit and accountability
The six cases illustrate that regulators actively enforce reporting obligations, and non-compliance—whether at the firm or state level—can lead to fines, corrective actions, and reputational damage.
