This is big news. It’s one thing for a few wayward Congressmen to talk about restoring Glass-Steagall protections, and quite another when one of the regional Federal Reserve Presidents endorses it. Thomas Hoenig of the Kansas City Fed has been better than most Fed Presidents during the crisis, even pushing for some kind of nationalization or resolution authority at one point. So perhaps he’s just an outlier, but hopefully he’s more like the proverbial canary in the coal mine:

Responding to a suggestion made by University of Maryland Professor Carmen Reinhardt, Hoenig said “dismembering firms is a fair thing to consider.” He said regulators “have people who are experts who understand what’s going on inside institutions” who could figure out how to “carve out” some parts of a financial institution if they are taking undue risks with taxpayer backing.

“We do need to consider some activities that are in these largest institutions that probably should not be trading for their account, gambling,” he said. “That portion probably does need to be separated out.”

This is part of a larger trend in the direction of restoring Glass-Steagall, even from the perspective of Wall Street. In addition to Hoenig, such people as John Reed, the former Citi CEO who pushed for Glass-Steagall repeal, have acknowledged that putting up a wall between commercial and investment banks makes sense. And in Congress, the push continues.

Ultimately, the White House would have to embrace the policy in order to really see some momentum. But Hoenig signing on is a good sign.
