Risky Banks Are Regulators’ Fault

It’s understandable that bank regulators, facing zealous industry opposition, are retreating from their effort to require the biggest lenders to fund their assets with more equity. After all, there hasn’t been a major blowup in 18 months and the banks insist they have more than enough capital.

The problem is that it isn’t true. Without stronger rules in place, the odds of another financial crisis — and massive bank bailouts — will continue to grow.

After the 2008 crisis led to the worst recession since the Great Depression, regulators around the world agreed on a plan — called Basel III — to ensure that bank shareholders (and not governments) would provide the capital needed to absorb losses. To calculate how much capital was needed, the plan modeled the risk of different assets — an inexact science that the banks could game.

The US enacted a backstop to those risk-weightings that required the eight biggest banks to have enough equity to fund at least 5% of their total assets, including off-balance sheet exposures. Even that seemed low: At least one projection in early 2009 estimated that US banks’ assets would lose a total of 10% of their value, while academics say banks should fund at least 15% of their assets with equity to avoid bailouts. But as new regulations took effect, and banks started losing business to less-regulated lenders and other financial service companies, political support for any tougher requirements dissipated.
