The EU has adopted an ambitiously wide-ranging post-crisis financial market regulatory reform agenda. Many of the most significant measures have been adopted and will be coming into force progressively over the next few years. The level of public intervention in markets that this frenzy of regulatory activity has involved is far removed from mainstream policy preferences of just a few years ago. Moreover, there has been a noticeable acceleration in the shift of power from Member States to EU centralized institutions and bodies. This paper is one part of a larger project that aims to take stock of the EU’s post-crisis financial market regulatory situation. The aim of the general project is to pinpoint the impact of the crisis on four key relationships - between Member States among themselves; between Member States and the EU Institutions; between the EU Institutions; and between the EU and the rest of the world – and to determine the potential longer-term consequences of these changing dynamics. This paper will examine these themes with particular reference to three areas in which there has been significant regulatory change: alternative investments, financial sector remuneration, and the supervisory architecture.
