The Markets in Financial Instruments Directive I (MiFID I) is a European Union regulation that was implemented in 2007. Its primary goal is to create a more integrated and competitive financial market across EU member states. MiFID I establishes a framework for the provision of investment services and aims to enhance investor protection and market transparency. MiFID I covers various aspects of financial markets, including the regulation of investment firms, trading venues, and the conduct of business. It requires firms to adhere to strict standards regarding client information, best execution practices, and the management of conflicts of interest, ultimately promoting fairer and more efficient markets.
