This report summarises the main results of a survey conducted by the European Capital Markets Institute (ECMI) during the period December 2009 - July 2010. The survey aims to investigate the actual implementation of the Markets in Financial Instruments Directive (MiFID), two years after it came into force. A general finding of this survey is that MiFID rules have had a positive impact, in particular, through fostering a more competitive environment, which has promoted, inter alia, cuts in trading fees and massive investment in technologies and infrastructure.
