Fool’s Gold and Organizational Inertia

Daniel Beunza at Socializing Finance links to Donald MacKenzie’s LRB review of Fool’s Gold, Gillian Tett’s new book on the financial crisis. I just finished reading the book, and I can only recommend it. Tett is an editor at the Financial Times; she also has a PhD in anthropology from Cambridge, which probably explains why the book somehow reads more like an econ-soc analysis of the crisis than as a journalistic account. In his review piece, MacKenzie gives a clear and detailed overview of the book’s main argument — and as such, his review is one of the best and most accessible accounts of the recent developments in structured finance I’ve read so far. But there’s a point that bothered me in the book, and which MacKenzie doesn’t seem to touch on:

Tett tells us about the crisis mostly from the standpoint of bankers and credit derivative specialists at J.P. Morgan — a bank which, by and large, stayed out the mortgage-backed securities mess and emerged relatively unscathed from the crisis. There’s nothing suprising about this: it is probably easier to find people willing to be interviewed on the crisis at J.P. Morgan nowadays than at, say, Citigroup or AIG. But this angle is precisely what makes the story so fascinating. The book starts from a simple but puzzling observation: the credit instruments at the center of the crisis (those pools of loans that were sliced into multiple tranches with distinct risk levels, which were in turn sold with overly optimistic ratings, aka collateralized debt obligations or CDOs) originated not from the home mortgage market but from the corporate bond market. Arguably, the crisis was largely caused by the belief that the same structured products could easily be used to transfer home mortgage risk away from banks’ balance sheets—although estimating the risk of CDO tranches turned out to be much more complex for mortgages than for corporate debt (in particular, there wasn’t any reliable data allowing to estimate the correlation of default probabilities). But surprisingly, the pioneer and leader in corporate debt CDOs, J.P. Morgan, decided not to further their advantage in structured finance: instead of moving into the mortgage-backed securities market and applying the same recipes they had just developed for corporate debt on a much wider scale, J.P. Morgan largely stayed out the market. Incentives were there: J.P. Morgan had expertise in such structured products; investment banks could collect enormous fees for underwriting CDOs and the market was booming; but JP Morgan executives, Tett observes, stayed on the sidelines and were even puzzled by the development of the market. So, what happened?

Tett’s account is essentially an organizational story. She argues that the prevailing culture at J.P. Morgan (a rather old-fashioned, boring and elitist institution) favored more prudent risk management strategies and more effective oversight than at other banks. This is an interesting hypothesis, but it may be, in part, the product of Tett’s methodology: the evidence supporting this argument comes mostly from interviews with J.P. Morgan executives — which are of course subject to response bias, recall bias and so forth. MacKenzie seems to generally agree with Tett’s thesis: what made J.P. Morgan different from other banks was the foresight of its management. Maybe reading too much organizational sociology has made me more cynical than I should be, but there’s an alternative explanation that Tett never fully explores or dismisses: organizational inertia. At the begining of the housing bubble, J.P. Morgan was specialized in corporate debt, and had no experience with home mortgages unlike BoA or Citi (J.P. Morgan was later absorbed by Chase Manhattan — but even then, only Chase got involved in mortgage CDOs). I do not doubt that organizational culture played an important role, but I did not see much evidence in the book that J.P. Morgan’s corporate culture (coupled with its expertise in structured finance) made its management more aware of the fragility of the mortgage CDOs than its competitors — if this were truly the case, one would have expected the bank to bet against the market by massively shorting CDO indexes, as a few hedge funds did. The alternative hypothesis, of course, is that organizational culture contributes to organizational inertia — and while it did not necessarily make J.P. Morgan’s executives more prudent or more aware of the risks inherent in the mortgage market, it may have prevented the bank from taking positions (long or short) in a segment of the industry it did not belong to.

    Interesting post.
    I’ve been wondering about the case of J.P Morgan myself.
    It seems that J.P. Morgan’s decision to stay away from CDOs is exactly the sort of response you would see if organizations think they are dealing with unknowns, not to bet against it. As you noted, J.P. Morgan was more confused about how the market was reacting to the CDOs than certain that it will blow up at some point.
