Of course, the recent credit crisis was caused by politician’s failure to regulate banks. Clearly, if banks had been properly regulated, we would not be in the mess we are in. And yet, even now, very little has been done to introduce new legislation to prevent further crises. What are the politicians playing at?
This is a typical response to the crisis, but not one I find convincing. To see why politicians have so far done almost nothing to alter the regulatory framework of the banking system, you only have to analyse the preceding paragraph closely. Far from being obvious and prescribing a straightforward course of action, the preceding statements contain a number of dubious assumptions. For example, do we really know what is meant by a bank? Defining a bank is no simple matter, as I argue extensively in The Metaphysics of Markets. Regulating by making distinctions between types of institutions (eg banks/non-banks) is only possible if ‘a bank’ can be clearly delineated. Regulating certain activities rather than certain persons or institutions is also rather tricky. With the use of structured products and derivative instruments (in particular those that trade over-the-counter ie directly between institutions rather than on-exchange), almost any type of trade can be replicated synthetically. In such cases, there is a futility in attempts to regulate.
Is this simply a counsel of despair then? Not quite, since effective regulation should be possible if a more considered approach is taken than has hitherto been the case. Simple definitions and characterisations of institutions must be reviewed. The theoretical problem with current legislation must be understood; after all, we do presently have some regulation (contrary to certain commentary). If our existing regulation is inadequate, we must try to see why, before simply tweaking it as we have done time and again in the past in response to other crises.
The apparent lack of political interest in these matters probably reflects an acknowledgement of the prima facie intractability of the issues. But the complexity of the problem at hand is rarely in itself adequate justification for not seeking a solution. And on this score more than any other, politicians certainly stand culpable.
