PUBLIC COMMENT PERIOD – MiFID II: Client LEI relationship scenarios



The Global Technical Committee has reviewed and preliminarily approved the MiFID II Client LEI relationship scenarios. The purpose of this document is to provide a standard approach for passing recording keeping information from firm to firm in an effort to meet the MiFID II Record Keeping and Transaction Reporting requirements with regards to client identification. The document outlines various approaches that FIX offers to identify the legal parties associated with placing an order and aims to create a standard for MiFID II client identification through the use of LEI (Legal Entity Identifier) codes.

The document now enters a public comment period in which public review and feedback is encouraged. Once the public comment period closes, the Global Technical Governance Board will meet to review public comments before final approval.

Please post feedback, comments, and questions as replies to this discussion thread.

The public comment period ends on August 16, 2018.


This is a really good document and very useful for describing various scenarios. A supplementary question, when the Order Placing Entity has a relationship with multiple sell-side entities what do we propose to use on the order so the OPE can direct the order to the intended broker entity?
