U.S. Fed governor, Daniel Tarullo, said in a recent speech that U.S. financial institutions could be required to meet stronger capital requirements than the Basel international standards. The Fed is considering requiring the riskiest financial institutions to put aside 8.4% to 14% of capital. The Basel standards require institutions to gradually increase the capital cushions to 7% by 2019 from about 2% at this time. Less risky institutions would would have a smaller increase over the Basel standards- about 20% compared to the 100% increase over Basel for the riskiest institutions. Speaking at the Peterson Institute for International Economics, Tarullo said- "The regulatory structure ...should discourage systemically consequential growth or mergers unless the benefits to society are clearly significant." Tarullo said no one wants to see another TARP. Banks would have to build up their capital reserves using common equity and not other forms of less reliable capital such as contingent capital, where banks convert debt instruments into equity in an emergency. Tarullo emphasized the need for the U.S. to move beyond the Basel requirements, known as Basel III, because they are narrowly designed for individual institutions and do not adequately address the systemic risk. When there is a high degree of risk correlation among many actors in fast moving markets additional risks are created which require stronger capital standards. Tarullo said systemically important institutions have "no incentive to carry enough capital to reduce the chances of such systemic losses."...
