At its 2010 summit in Seoul, South Korea, the G-20 collectively endorsed a new collection of capital adequacy and liquidity standards for banks recommended by Basel III. Andreas Dombret of the Executive Board of Deutsche Bundesbank has noted a difficulty in identifying institutions that constitute systemic importance via their size, complexity, and degree of interconnectivity within the global financial system, and that efforts should be made to identify a group of 25 to 30 indisputable globally systemic institutions. He has suggested they be held to standards higher than those mandated by Basel III, and that despite the inevitability of institutional failures, such failures should not drag with them the financial systems in which they participate. Dombret has advocated for regulatory reform that extends beyond banking regulations and has argued in favor of greater transparency through increased public disclosure and increased regulation of the shadow banking system.
