More Wall Street Leverage Won’t Help Main Street

Like hemlines and hairstyles, trends in bank rules seem to shift with the times.

Just three years ago, regulators suggested that the biggest banks needed about 19% more capital to protect against potential losses. Now, after a furious industry reaction and personnel changes at key agencies, they’re recommending a decrease of some 6% in aggregate, in hopes of reducing complexity and boosting lending. That’s after capital ratios had already started drifting lower.

Unfortunately, the benefits of these latest proposals are likely to be marginal at best. More certain is that they’ll make an already highly levered financial system even riskier.

Streamlining the rules is undoubtedly appealing. The new proposal would do this, in part, by allowing the largest banks to use one method to calculate the risk of their assets instead of two, as currently required. That makes sense as far as it goes. Yet other requirements — including leverage ratios and certain capital surcharges — are being loosened or otherwise made more bank-friendly at the same time. The risk is creating a rule book that’s more lenient but still overly complicated.

A second objective for the administration is to help banks play a bigger role in lending to homeowners and businesses. Fintechs and other nonbank lenders have come to dominate residential mortgages, while investment funds are now aggressively lending to companies. Banks say that their regulations and elevated capital requirements are to blame. No doubt there is some truth to that — banks are held to a higher standard because they benefit from deposit guarantees and other forms of federal support.
