The risks of consolidation

Posted by: Felix Salmon
Tags: economics,

I had a short chat with Nassim Taleb this morning about his new paper with Charles Tapiero, entitled “Too Big to Fail, Hidden Risks, and the Fallacy of Large Institutions”.

There’s a great deal of mathematics in the paper, which is full of equations and greek letters, but the gist of it is explained in pretty plain English:

Societe Generale lost close to $7 Billions dollars, around $6 Billions of which came mostly from the liquidations costs of the (hidden) positions of Jerome Kerviel, a rogue trader, in amounts around $65 Billions (mostly in equity indices). The liquidation caused the collapse of world markets by close to 12%. The losses of $7 Billion did not arise from the risks but from the loss aversion and the fact that costs rise disproportionately to the size of the bank…

Consider the following two idealized situations.

Situation 1: there are 10 banks with a possible rogue trader hiding 6.5 billions, and probability p for such an event for every bank over one year. The liquidation costs for $6.5 billion are negligible. There are expected to be 10 p such events but with total costs of no major consequence.

Situation 2: One large bank 10 times the size, similar to the more efficient Société Génerale, with the same probability p, a larger hidden position of $65 billion. It is expected that there will be p such events, but with $6.5 losses per event. Total expected losses are p $6.5 per time unit – lumpier but deeper and with a worse expectation.

In other words, small mistakes we can live with. Large mistakes we can’t, because when a mistake the size of Kerviel’s is unwound, the costs are enormous — not only to SocGen, which lost upwards of $6 billion, but also to all shareholders globally, who saw the value of their holdings marked down by trillions of dollars thanks to the effects of SocGen’s enormous and chaotic forced unwind.

The lessons here are broader, and apply to the practice of M&A more generally: when industries consolidate, there might well be economies of scale — but at the same time tail risks increase. What happens when a massive amount of technology outsourcing is consolidated in Bangalore, or computer-chip manufacture is consolidated in Taiwan? Efficiency rises — but so does the risk that one disastrous event could have massive systemic consequences.

The solution for banks is relatively simple: just put a cap on their size. (I’ve been suggesting $300 billion.) What’s the solution for other industries, which also naturally tend to consolidate and cluster? I’m not sure, but in an increasingly interconnected and just-in-time world, the risks are greater than ever."

Me:

There’s a good post on this at The Economics Of Contempt:

http://economicsofcontempt.blogspot.com/ 2009/05/too-big-to-fail-experts-on-make- them.html

He mentions the following post:

“Addressing TBTF by Shrinking Financial Institutions: An Initial Assessment Gary H. Stern President Federal Reserve Bank of Minneapolis Ron Feldman Senior Vice President Supervision, Regulation and Credit Federal Reserve Bank of Minneapolis”

It’s a good and sensible post. Here’s one quote:

“On the first point, we anticipate that policymakers would face tremendous pressure to allow firms to grow large again after their initial breakup. The pressure might come because of the limited ability to resolve relatively large financial institution failures without selling their assets to other relatively large financial firms and thereby enlarging the latter. We would also anticipate firms’ stakeholders, who could gain from bailouts due to TBTF status, putting substantial pressure on government toward reconstitution. These stakeholders will likely point to the economic benefits of larger size, and those arguments have some heft. Current academic research finds potential scale benefits in all bank size groups, including the very largest.3 (Indeed, policymakers will have to consider the loss of scale benefits when they determine the net benefits of breaking up firms in the first place.)”

This makes sense to me, and even applies to the idea of taxing the size of banks, which I prefer. I prefer Narrow/Limiting Banking precisely because it’s harder to change politically. No doubt, there will be movements to change it. But we need a simple plan with simple rules. We’ve proven that we can’t handle complexity or lobbying or regulating very well.

An, yes, I bring this up just so that this plan will be considered. By the results so far, I’m not really the best person to advance this plan.

How do we eventually escape the grip of zombie oligarchs? We’ll have a fair amount of time to think that through.

From The Baseline Scenario:

"Zombie Oligarchs

with 23 comments

At this stage in any economic stabilization process, the state-sponsored lifeboat for oligarchs starts to get a little crowded. Governments don’t have enough resources to save everyone, and not all major borrowers can have their debts rolled over. In emerging markets, it’s usually the shortage of foreign exchange that sets a limit on government largesse (see the start of our Atlantic article for more detail on this cycle); in the US and other industrial countries, it’s more complicated – mostly about constraints around bailout politics (Lorenzo Bini Smaghi made this point effectively in the fall).

The survival-failure decision is taken at the highest level. In April 2008, after the failure of Bear Stearns, Dick Fuld had dinner with Hank Paulson and reportedly concluded, “We [Lehman] have a huge brand with Treasury.” As the broader problems within the financial system worsened, this proved worth less than he thought.

Fuld is still in shock, and seething. How could Paulson let Lehman go? “Until the day they put me in the ground, I will wonder [why we weren’t saved],” he told Congress.

This week, Daniel Bouton resigned from running SocGen, in the face of what he called “incessant” verbal attacks – a reference presumably to lack of support from Mr. Sarkozy; it’s not good when the President of France calls your proposed pay package “a scandal”. And Ken Lewis may take a further battering - due in part to not being the best-connected with top people in Washington.

Some powerful people, naturally, can take this opportunity to elbow others out of the way. A better reputation in the right circles or somewhat deeper pockets or the ability to pay higher compensation will carry you a long way while your competitors are having a hard time getting back on their feet.

Mancur Olson famously argued that crises can break the power of vested interests. That’s possible, but only happens when the crisis brings the right kind of reformer to power. More often, crises lead to greater concentration of economic power and political influence.

This can be consistent with the resumption of rapid growth – after crises, some emerging markets just as fast, or even faster, than before. But such an outcome seems unlikely today for the US and for the world.

There are three reasons why today’s surviving oligarchs are not likely to prove immediately dynamic.

  1. They have a lot of debt. In emerging markets, this is the prevailing problem. The debts of powerful people are being rolled over, but at high interest rates. There is nothing in this part of our broader balance sheet issues that points towards new investment and expansion.
  2. They are worried about future reshuffles of power. Obviously, the U.S. Treasury is involved in an awkward parent-adolescent shouting match with big banks (who is who?). The banks likely reckon that they will win on the whole, but individual banks or particular CEOs may still suffer blows – through the politics of stress tests, the way compensation caps are limited, or something else. This kind of uncertainty and continuing struggle is unlikely to encourage expansion.
  3. The most significant difference between the US today and many emerging market crises in the past is the exchange rate. Post-crisis booms are often triggered by big nominal exchange rate depreciations – if you can hold the line on inflation (the IMF can help, and you can blame them for unpopular measures; perfect), then exports become hypercompetitive and you start a new cycle of capital inflows. Even Japan had a strong export sector throughout the zombie bank doldrums of the 1990s. The dollar, of course, is still the world’s preeminent reserve currency and problems in the eurozone mean this will continue for the foreseeable future; significant real depreciation is unlikely in the near future. And at the global level, we can’t export our way out of this – there is no way that Mars can develop quickly enough as an export market.

Some new entry and productive reallocation of talent is possible in this situation. For example, John Mack is saying that pay caps mean his bankers are leaving – among other things – for “other industries”. But the G20 policy of stabilization-through-rollover, at the national and corporate level, means that incumbents’ implicit subsidies actually go up. The environment for starting businesses in the US has not completely collapsed, but it has also definitely not improved.

So we get to keep many of our oligarchs, but relative to the recent past they will hunker down. You might be fine with that – although remember that it does not prevent reckless risk-taking and an increase in your taxes down the road. Larry Summers says this happens only twice per century, but his own argument is that we have moved away from the kind of financial system that was built in the mid-20th century. If we’ve gone back to the wilder days of the 19th century, the cycles could be quite different (look at the NBER’s data). If the US has really become more like an emerging-market-with-a-reserve-currency, that is also not encouraging.

We’re looking at a near term dominated by the existing economic power structure. The remaining big banks (in the US) and big banks/corporates (elsewhere) are made invincible by campaign contributions, political connections, and everyone’s reasonable fear of a great depression. It will be hard for outsiders to challenge that structure effectively – either as new companies or with new ideas. But you won’t see a great deal of innovation, investment, and growth coming from these survivors.

How do we eventually escape the grip of zombie oligarchs? We’ll have a fair amount of time to think that through.

Me:

One of the reasons that I think that Narrow/Limited banking might catch on is that it is a conservative proposal largely backed by more liberal or moderate politicians. It is mainly associated with Irving Fisher, Frank Knight, Henry Simons, and Milton Friedman. On the other hand, the Lib Dems are currently behind it in some sense, as is Buiter.

Since I follow Burke in preferring Reform to Revolution, I’m willing to accept a rather long and arduous process. On Narrow Banking, here:
