Deus Ex Macchiato

More goodies from from Piergiorgio Alessandri and Andrew G Haldane:

Hedge funds started this crisis in the doghouse. Yet they are the dog that has not barked. Their industrial structure may explain why. Unlike banking, the hedge fund sector does not comprise a small number of large players, but rather a large number of relatively small players. The largest hedge funds typically have assets under management of less than $40bn, the largest banks assets in excess of $3 trillion.

Unlike banking, concentration in the hedge fund sector is low and has been falling. The top 5 hedge funds comprise around 8% of total assets, down from 30% a decade ago. Unlike banking, the business models of hedge funds are typically specialised rather than diversified…

It may be coincidence that the structure of the hedge fund sector emerged in the absence of state regulation and state support. It may be coincidence that the majority of hedge funds operate as partnerships with unlimited liability. It may be coincidence that, despite their moniker of “highly-leveraged institutions”, most hedge funds today operate with leverage less than a tenth that of the largest global banks. Or perhaps it might be that the structure of this sector delivered greater systemic robustness than could be achieved through prudential regulation. If so, that is an important lesson for other parts of the financial system.

The point is excellent. While there have been hedge fund losses during the crunch, the hedgies have not endangered financial stability to anything like the extent that regulated financial institutions have. This could well be because they are diversified in their risk taking, relatively small, and typically not highly leveraged. It is clear that 10,000 small, diverse, low leverage firms form a much more stable financial system than 10 huge, similar, highly leveraged ones.
