A Further Thought on the Volker-Obama Plan
I think it’s always worthwhile to work through the likely equilibrium effects of policy changes, to recognize that such changes will affect not only what is directly targeted, but will also induce other responses that can dampen, and even reverse, the intended effects of the policy change.
Let’s consider the unintended, equilibrium effects of Volker-Obama. The V-O plan should affect big deposit taking institutions–universal banks–most acutely. JP Morgan-Chase, Citi, BofA in particular. The plan essentially forces firms to make a choice between being depository institutions or prop shops. (Backdoor Glass-Stegall, if you will.) The cost of becoming a prop shop would be very high for Morgan, etc. So they are likely to jettison these operations, and become relatively old style banks again. And that’s exactly what Obama and Volcker want.
But consider the effects of the exit of some players from prop trading. They were presumably in the prop trading business because it was profitable. Their exit creates a profit opportunity for somebody else. In the first instance, potentially a Goldman or MOST that can become pure prop shops exempt from the restrictions at lower cost than Morgan, Citi, and BofA. Moreover, currently smaller players may expand their prop trading, or new entrants will come in to take advantage of the opportunities.
In other words, someway, somehow, the exit of the deposit taking banks from prop trading will induce expansion and entry by others. These others, in turn are likely to be quite large and systemically important. Especially because VO doesn’t address the underlying source of TBTF–the government’s inability to commit NOT to intervene to bailout the creditors of a failing, interconnected, failing institution. (Thought experiment: V-O is likely a boon to Citadel and D.E. Shaw. Thinking back to LTCM, do you think that if one of these firms got into serious trouble, that some sort of government intervention would occur? Yeah, the investors in the hedge funds would be wiped out, but that’s not the point. To the extent that their counterparties, and the banks that finance their operations are convinced that they would be protected in the event of a big hedge fund collapse, they are willing to trade with and extend credit to them, permitting them to expand excessively.)
This means that equilibrium responses will undermine the effects of VO. It is likely that VO will reduce the amount of prop trading, especially if there are synergies between this activity and other forms of intermediation offered by universal banks. But it may lead to a greater concentration of what prop trading remains in the hands of a smaller number of less diversified firms. Remember that the main casualties of the crisis were, in the first instance, Bear Stearns, Lehman, Merrill, and almost Morgan Stanley and Goldman. If anything, the V-O plan would increase the number, size, and importance of these kinds of firms. That’s hardly reassuring. Yes, these types of firms would not benefit from the deposit insurance system, but that doesn’t mean that they aren’t effectively guaranteed anyways if they become big enough.
Yes, we definitely need to do something to deal with moral hazard. I’m just not convinced that the V-O framework does that. Given that prop trading is apparently profitable, V-O will lead primarily to a shifting around of who does prop trading. Yes, deposit taking institutions will do less of it, but others will swoop in to take advantage of their exit. We’ll still be left with implicitly guaranteed institutions with an incentive to grow too large.
