LEI Regulation Spotlight
MiFID II - Markets in Financial Instruments Directive
Overview
Discover how MiFID II and EMIR standardise trade and derivatives reporting, and how the LEI ensures accurate identification of all parties to financial transactions.Objectives and scope
The directive applies to investment firms, trading platforms, market operators, and data-reporting service providers. It requires every client and counterparty in reportable transactions to be uniquely identified.
MiFID II has applied since 3 January 2018.
MiFID II mandates LEI use under the principle of “No LEI, No Trade.” Firms cannot execute transactions for clients that do not possess a valid LEI. Reporting templates require LEIs for:
- The executing investment firm
- The client or counterparty
- The issuer of the financial instrument
This requirement has driven LEI adoption across Europe and influenced global practice.
Why organisation identity matters
Regulators must trace the full chain of a transaction to detect misconduct or systemic risk. The LEI provides a single, authoritative identifier that ensures accurate counterparty data and prevents duplicate or rejected reports.Implementation insight
