Learn key rules around the investor protection framework and how it impact your organisation.
MiFID is a cornerstone of EU financial regulation, shaping how investment firms operate, interact with clients, and distribute financial products. It establishes a harmonised framework to promote transparent, fair, and efficient markets while strengthening investor protection and trust across the financial system.
MiFID II is the EU’s primary legislative framework governing investment services and activities. It has applied across the European Economic Area since January 2018, replacing the original Markets in Financial Instruments Directive (MiFID I) and extending its scope to cover investment firms, trading venues, data reporting service providers, and third country firms accessing EU markets. The directive establishes rules governing how financial instruments are traded, how clients must be protected, how firms must organise themselves internally, and how markets must operate — spanning client classification and suitability, product governance, costs and charges disclosure, best execution, and transaction reporting. Read together with its accompanying regulation, MiFID II is the cornerstone of EU capital markets regulation, across asset managers, credit institutions, brokers, investment advisers, and any entity providing investment services or performing investment activities within the EEA. MiFID II fundamentally reshapes how investment services are delivered across Europe — its reach extends from front-office conduct to back-office reporting, and from retail client protection to wholesale market structure.
MiFID II has three key pillars according to the regulator’s objectives:
MiFID II sets detailed requirements for how firms must treat their clients — from initial classification through ongoing suitability assessments, product governance, and disclosures.
The framework imposes extensive pre- and post-trade transparency requirements on trading venues and systematic internalisers, aiming to improve price discovery and market efficiency across asset classes.
MiFID II is one of the central pillars of supervisory surveillance across the EU, establishing harmonised conduct obligations that national competent authorities are required to actively monitor and enforce. In Luxembourg, the CSSF has consistently designated MiFID II as a priority topic within its annual supervisory programme, reflecting the jurisdiction's role as a major hub for cross-border investment services and fund distribution. On-site inspections targeting MiFID II compliance are conducted on a recurring basis, making a robust and audit-ready compliance framework an operational necessity for any firm active in the Luxembourg market.
Pillars define the regulatory substance of MiFID II — each with distinct firm-level obligations:
MiFID II is an in-force framework — its core rules apply today, while targeted reforms continue to refine specific areas of the regime.
Assessment of a firm's existing MiFID II framework against applicable regulatory requirements, identifying deficiencies and prioritising remediation actions through structured gap-to-compliance mapping.

End-to-end regulatory support when a firm launches or expands investment services, covering the design of the control framework, drafting of client-facing documentation, policies and procedures, and translation of regulatory requirements into operational and system specifications.
Guidance through the CSSF authorisation process for firms seeking to extend their existing licence with additional MiFID II investment services or activities, including application file preparation and regulatory dialogue support.
