MIFID: Markets in Financial Instruments Directive

An extensive overview of the Markets in Financial Instruments Directive (MiFID), its historical context, key provisions, implications, and related terminologies.

The Markets in Financial Instruments Directive (MiFID) is a cornerstone of the European Union’s financial regulation framework. It was designed to increase competition and consumer protection in investment services across the EU’s financial markets.

Origin

MiFID I, introduced in 2007, aimed to harmonize regulation across European financial markets and improve consumer protection. In response to the 2008 financial crisis, MiFID II and its accompanying regulation MiFIR (Markets in Financial Instruments Regulation) were introduced in 2018 to enhance market transparency and strengthen the financial system.

Investment Firms

Trading Venues
