The financial crisis prompted financial supervisors to take a critical look at their own performance. Supervision has become more forward-looking, taking into account also soft controls, such as conduct and culture´, corporate governance, and business models of financial institutions. The 'toolkit' available to supervisors is considerably more varied than it was a few years ago. This collection of essays discusses several significant changes in supervision methods and supervisory organisations and examines what methods contribute to good supervision´ and what can reasonably be expected of supervisors. The authors are experts in the field and most of them are affiliated to organisations responsible for financial supervision.
