This paper gives an overview of the efforts, worldwide and on a regional i.e. European level basis for introducing more effective and better harmonised financial regulation. Recent initiatives especially the work of the G 20 and the creation of the Financial Stability Board (FSB) indicate greater interest for worldwide coordination of financial regulatory intervention. The financial crisis has however dealt a serious blow to previously existing international dialogue, and the fear exists that the main regulators would withdraw on their national battlefields. Major changes in the supervisory architecture are planned in the European Union: a proposal has been tabled to introduce a coordinated approach to regulation and to monitoring the way existing regulations are applied by putting into place a European system of Financial Supervisors. At the same time a new European Systemic Risk Board will be created. These, and comparable changes in the US may contribute to reactivate the regulatory dialogue.
