In capital we trust. Capital is our savior, our holy grail, our fountain of youth, or at least health, for banks. Seriously, how many times have you read that more capital will save the banks from another Armageddon? Even the banks point to capital as a reason to have faith. “Financial institutions have also been working alongside regulators to make themselves and the financial system stronger, more transparent, more resilient and more accountable,” wrote Rob Nichols of the Financial Services Forum, which is made up of the chief executive officers of 19 big U.S. financial institutions. “Specifically, capital, which protects banks from unexpected losses, has doubled since 2009.” If you were a cynic — who, me? — you might say that the mere fact that the banks are pointing to capital is proof that capital is not all that.
