Fed’s Tarullo not making any promises

We’re pretty sure that Daniel Tarullo, the Federal Reserve’s point person on regulation, expects the United States will finally understand exactly what financial reforms are coming “some time next year.” But the Fed governor made doubly sure to qualify that statement lest anyone – especially any press “in the back” – take it as gospel.

At a conference in New York Wednesday morning, Tarullo was asked how long it would take for the various regulatory agencies to give final details on the raft of financial crisis-inspired reforms, everything from Basel III capital standards to the Volcker ban on proprietary trading. Here’s what he said:

“I know it’s frustrating for people not to have the proposed rules out. On the other hand, doing them simultaneously does allow us to see whether something in one of the proposed capital rules will affect something in another proposed capital rule, so that we end up, when we publish the final rules, with fewer anomalies, questions and the like, which will undermine the ability of a firm or academic or just anyone in the public to see and understand how these things are going to function. I hesitate to give a time line on exactly when we’ll get there. But I think…it seems to be reasonable to expect that some time next year the basic outlines – and I don’t just mean the ideas, I mean the details associated with the major reform elements – should be reasonably clear to people even though questions will inevitably rise in implementation. (You) don’t want to take that as a promise. But as I think about these various streams, that is my expectation… To have gotten it done this year would have meant the sheer magnitude of the task would have lead to a lot of inconsistencies or open questions, which then would have just produced another round of change. So you’ve got me on the record saying some time next year, but I tried to qualify it as much as possible – that’s for all you people in the back…”

When speculation squashes innovation

Paul Volcker famously joked in the wake of the 2008 credit crisis that the most important financial innovation of the last few decades had come not from Wall Street’s fancy footwork but rather the engineering acumen that created the ATM. A paper published by the National Bureau for Economic Research lends some academic credence to Volcker’s view. In particular, the research of Alp Simsek, a Harvard economist, finds the very uncertainty that esoteric new securities introduce into financial markets eats away at benefits arising from greater credit availability:

Financial innovation always decreases the uninsurable variance because new assets increase the possibilities for risk sharing. My main result shows that financial innovation also always increases the speculative variance. This is true even if traders completely agree about the payoffs of new assets. The intuition behind this result is the hedge-more/bet-more effect: Traders use new assets to hedge their bets on existing assets, which in turn enables them to place larger bets and take on greater risks. This effect suggests that financial innovation is more likely to be destabilizing in more complete financial markets and when it concerns derivative assets.

The author argues that rules prohibiting too many new types of securities from being introduced at once – so that traders don’t go too crazy too quickly – isn’t enough. As the crisis showed, when push comes to shove, hard-and-fast rules deliver better results than efforts at industry self-discipline.
