Experts from think tanks, governments, and international organizations like the IMF and European Commission met in Brussels to discuss proposals for taxing the financial sector. They aimed to take stock of post-crisis actions, revisit debates on financial taxes, and assess remaining challenges. Participants agreed that the financial sector should contribute fairly to addressing costs of banking crises, and that more than one tax may be needed to serve different objectives like financing future government interventions. The discussions covered existing bank levies in over a dozen countries as well as debates on financial transactions taxes and alternative "financial activities taxes."
