MiFIR Transaction Reporting Under Article 26 at a Glance

Under Article 26 MiFIR, investment firms must report executed transactions in reportable financial instruments completely and accurately by the end of the following working day (T+1) to their national competent authority — in practice usually via an Approved Reporting Mechanism (ARM). Each report comprises up to 65 data fields: from LEI identification of the parties involved and the flagging of decision-makers and executing persons to instrument data that must be reconciled against ESMA's FIRDS reference database.

7 QUESTIONS, BRIEFLY ANSWERED

Frequently asked questions about MiFIR Transaction Reporting: Article 26, 65 Fields, LEI & FIRDS Reference Data | ADVISORI

What is MiFIR transaction reporting under Article 26?

MiFIR Article 26 transaction reporting obligates investment firms to report every transaction in financial instruments to the competent national authority. Reports must be submitted by the end of the following business day (T+1) and contain up to 65 data fields covering clients, counterparties, instruments, price, quantity and timestamps. The purpose is to enable market surveillance and detection of market abuse across EU financial markets.

What are the 65 fields in a MiFIR transaction report?

The 65 fields are grouped into seven categories: client information (name, LEI or national identifier), counterparty data, transaction details (price, quantity, currency, execution timestamp), instrument data (ISIN, CFI code, underlying), trading venue information (MIC code), processing fields (transaction reference number, report status) and decision-maker information (trader ID, algorithm ID). Each field has specific validation rules defined in RTS 25.

Who is required to report under MiFIR Article 26?

All investment firms executing transactions in reportable financial instruments are subject to the reporting obligation. This includes banks and securities trading firms with trading activities. Firms can submit reports directly to the national competent authority or delegate submission to an Approved Reporting Mechanism (ARM). Even when delegating, the reporting firm retains responsibility for data accuracy and completeness.

What is FIRDS and how does it relate to transaction reporting?

FIRDS (Financial Instruments Reference Data System) is ESMA's central database for instrument reference data. Trading venues and systematic internalisers report their instruments to FIRDS. When submitting transaction reports, the instrument details must match FIRDS records — particularly ISIN, CFI code and trading venue MIC. Missing or inconsistent FIRDS entries are a frequent source of reporting errors and rejections.

Why is the Legal Entity Identifier (LEI) critical for transaction reporting?

The LEI is a 20-character alphanumeric code that uniquely identifies legal entities worldwide. For MiFIR transaction reporting, all involved legal entities — the ordering party, counterparty and reporting firm — must hold a valid, active LEI. Expired or inactive LEIs cause report rejections. Regular LEI renewal and validation is therefore a critical component of the reporting process.

What are common errors in MiFIR transaction reporting?

Typical error sources include invalid or expired LEIs, incorrect ISIN codes, wrong trading venue MICs, incorrect timestamp formats, incomplete client identification for natural persons, and inconsistencies between reported and FIRDS-registered instrument data. Correctly distinguishing between new submissions, cancellations and corrections is also error-prone.

How does ADVISORI support MiFIR transaction reporting implementation?

ADVISORI provides comprehensive transaction reporting advisory: gap analysis of existing reporting processes, mapping of 65 fields to internal data sources, implementation of validation rules per RTS 25, ARM system integration, LEI management and FIRDS reconciliation. We also support preparation for the MiFIR review changes and train specialist teams in compliant reporting processes.
