MiFID II
Six years after the European Commission first published its initial proposals, the revised Markets in Financial Instruments Directive and the accompanying Markets in Financial Instruments Regulation – better known as MiFID II and MiFIR – will come into effect across all EU member states from January 2018.
MiFID II is intended to build on the achievements of MiFID I, with the aim of making financial markets more open, efficient, resilient and transparent. The initial focus on extending transparency and competition across asset classes has grown to cover new customer protections, controls in areas such as algorithmic trading, and the implementation of obligations imposed by the G-20 largely as a result of the 2008 financial crisis.
Under MiFID II the transparency requirements that currently apply to equities markets will now be expanded and adapted for the fixed income and derivatives markets. For investors, the enhanced conduct rules it sets out will lead to significantly increased protection. MiFID II also sets out a range of more prescriptive measures and obligations for a trading venue’s trade and transaction reporting and publication of real time data.
