That is my latest Bloomberg column, here is one excerpt:
Looking at a broad swath of history, I see three major forces that can make financial systems safer: people being scared by recent events, solid economic growth and reduced debt in comparison to the value of equity. The financial crisis gave us the first on that list as perhaps its main “gift” (for now), but Dodd-Frank may have worsened economic growth problems.
On the plus side, we might like to think that Dodd-Frank improved the debt-equity balance by pushing banks to raise more capital. But that, too, now stands in doubt.
Last week Natasha Sarin and Lawrence H. Summers of Harvard University released a paper questioning whether Dodd-Frank has made big U.S. banks safer at all. The authors look at a variety of measures, including options prices, the ratio of market prices to book values, bank share volatility relative to overall market volatility, credit-default swap spreads and the value of preferred equity shares for banks. In every metric, it seems that the big banks are at least as risky as they were before the crisis, in part because they have lower capital values.
It’s a common economic prescription that regulation should insist that banks carry high levels of capital to withstand losses in bad times. But although Dodd-Frank raised statutory capital requirements, it may have drained banks of some of their true economic capital by regulating and sometimes prohibiting valuable banking activities. The ratio of market price to book value has declined for the biggest banks, and that is one sign of falling values for true economic capital, even though banks have met the letter of law by increasing capital as the regulations specified. Sarin and Summers note that measures of bank capital, as defined by regulators rather than the market, have little predictive power for bank failures.
