Solving the Too Big to Fail Problem

Posted: 16 Nov 2012 01:18 PM PST

William Dudley, President of the NY Fed, on too big to fail (this is just a small part of his much longer, detailed discussion):

Solving the Too Big to Fail Problem, by William C. Dudley, President and Chief Executive Officer, FRBNY: ...I am going to focus my remarks today on what is popularly known as the "too big to fail" (TBTF) problem. In particular, should society tolerate a financial system in which certain financial institutions are deemed to be too big to fail? And, if not, then what should we do about it?

The answer to the first question is clearly "no." We cannot tolerate a financial system in which some firms are too big to fail—at least not ones that operate in any form other than that of a very tightly regulated utility.

The second question is the more interesting one. Is the current approach of the official sector to ending TBTF the right one? I'd characterize this approach as reducing the incentives for firms to operate with a large systemic footprint, reducing the likelihood of them failing, and lowering the cost to society when they do fail. Or would it be better to take the more direct, but less nuanced approach advocated by some and simply break up the most systemically important firms into smaller or simpler pieces in the hope that what emerges is no longer systemic and too big to fail?1

As I will explain tonight, I believe we should continue to press forward on the first path. But, if we fail to reach our destination by this route, then a blunter approach may yet prove necessary. ...

Critics of our approach believe it would be better to just break up firms deemed TBTF now—perhaps through legislation requiring the separation of retail banking and capital markets activities or by imposing size restrictions that require firms to shrink dramatically from their current scale. My own view is that while this could yet prove necessary, it is premature to give up on the current approach: changing the incentives facing large and complex firms, forcing them to become more resilient, and making the financial system more robust to their failure.

In my opinion, there are shortcomings to reimposing Glass-Steagall-type activity restrictions or strict size limits. With respect to Glass-Steagall, it is not obvious to me that the pairing of securities and banking businesses was an important causal element behind the crisis. In fact, independent investment banks were much more vulnerable during 2008 than the universal banking firms which conducted both banking and securities activities. More important is to address the well-known sources of instability in wholesale funding markets and give careful consideration to whether there should be a more robust lender of last resort regime for securities activities.

With respect to size limitations, it is important to recognize that a new and much reduced size threshold could sacrifice socially useful economies of scale and scope benefits. And it could do this without actually solving the problem of system risk externalities that aren't related to balance sheet size.

Evaluating the socially optimal size, scope and organizational structure of financial firms is a complicated business, and so is establishing a viable transition path to a system of much smaller firms. It would be helpful in this regard if advocates of break-up solutions would put a bit more flesh on the bones and develop detailed proposals that address essential questions of how such downsizing or functional separation would be accomplished, and what benefits and costs could be expected.

Such an analysis should answer several questions: How would you force divestiture (in good times and bad)? Should firms be split up by activity or reduced pro-rata in size? How much would they have to be shrunk in order for the externalities of failure to no longer create TBTF problems? How would global trading and investment banking services and network-type activities be supported? Should some activities be retained in natural monopoly form, but subject to utility type regulation? How costly would it be to replicate support services or to manage liquidity and capital locally? Are there ways of designing size limits that cannot be arbitraged by banks via off-balance-sheet structures and other forms of financial innovation? So far, advocacy for the break-up path has been strong, but without the detail to assess whether this is indeed superior to the course we are currently following. But, I'm open-minded.

It is important to recognize that any credible approach to addressing the TBTF problem, including the one we are pursuing today, necessarily implies changes to the structure and business mix of financial firms and financial markets. Moreover, it is important to stress that not all of these adjustments will be in the private interests of these firms, and some will result in changes to the price and volume of certain financial services. These are intended consequences, not unintended consequences.

Too big to fail is an unacceptable regime. The good news is there are many efforts underway to address this problem. The bad news is that some of these efforts are just in their nascent stages. It is important that as the crisis recedes in memory, that these efforts not flag—this is a project that needs to be seen to a successful conclusion and then sustained on a permanent basis.

Thank you...

One thing we really need to understand better is the minimum efficient scale for various financial activities. Whenever the topic of breaking banks into smaller pieces is raised, we hear that a "much reduced size threshold could sacrifice socially useful economies of scale and scope benefits." The key word is "could." As far as I can tell, the evidence on this point is very shaky -- we just don't know for sure what size is necessary to exploit efficiencies. My own view is that it is likely smaller than many firms today, and hence there would be no harm in reducing firms size. This may not help much with stability, but there are still perhaps many benefits (e.g. reduced political and economic power) from reducing firm size and increasing the number of institutions engaged in important financial activities.
