The book analyses the institutions of the European financial market supervision and the challenges of financial markets. The current European supervisory structure for financial markets represents a major development in European supervisory history. Its operation however has to be explored and analysed critically. Has it gone far enough to provide a sufficiently comprehensive and resilient system to reduce or mitigate systemic risks and handle financial crises? Some claim it has gone too far already. Fresh and rigorous critical legal and economic analysis from an independent scholarly perspective are needed to assess whether the institutional design of the European supervisory architecture has proved itself to be an efficient and effective model. This book discusses many dimensions of the structure and workings of the European system from various angles providing different dimensions. The book makes an important contribution to the limited literature on financial market supervision.
