The unimpaired functioning of financial markets and the protection of investors and savers presuppose the implementation of financial regulation capable of preventing and sanctioning illicit practices consisting of market failures or abuses. The increasing complexity of financial activities may make it more difficult to characterize illicit practices and thus to deter them by means of pecuniary or financial penalties in the context of litigation proceedings. This article explores the interests and limits of three of the avenues open to the financial regulator to respond to these difficulties: the use of transactional procedures, the implementation of procedural regulation strategies and, finally, the use of algorithmic regulation devices.
