Directive 2014/65/EU establishes a comprehensive regulatory framework for financial markets in the European Union, focusing on improving transparency, protecting investors, and ensuring harmonious practices across member states. It sets out requirements for investment firms, market operators, and data reporting services providers, including authorisation and operational conditions, independent conduct of business obligations, and specific provisions concerning algorithmic trading and trading venues. The directive aims to enhance the functioning and integrity of financial markets while addressing identified weaknesses revealed during the financial crisis.

The directive introduces rigorous governance standards for investment firms and outlines the necessary measures for compliance with capital requirements and operational frameworks. Member states are tasked with ensuring adherence to these regulations by their respective competent authorities, promoting cooperation among jurisdictions, and enforcing penalties for non-compliance, thereby fostering a more resilient and consumer-friendly financial landscape.
