(35)A sound prudential and conduct of business framework for the financial sector should rest on strong supervisory, investigatory and sanctions regimes. To that end, competent authorities should be equipped with sufficient powers to act and should be able to rely on equal, strong and deterrent penalties regimes for the infringements of this Directive. A review of existing powers to impose sanctions and their practical application aimed at promoting convergence of sanctions across the range of supervisory activities was carried out in Commission Communication of 8 December 2010 on reinforcing sanctioning regimes in the financial services sector. Competent authorities should be empowered to impose pecuniary penalties which are sufficiently high to be effective, dissuasive and proportionate, in order to offset expected benefits from behaviour which infringes the requirements laid down in this Directive.
