Credit crunch?

As we look at how to define the history of this crisis (read the Stiglitz piece in Vanity Fair, Capitalist Fools), we must question all our assumptions. An interesting question to answer is, was there a credit crunch?

I guess one could argue that credit is there for the taking and, beyond the original *confidence* crisis (where companies didn't trust each other's balance sheets), there is not broader credit crunch. Part of me says that banks must have retrenched to protect their balance sheets, but the other part says that if banks need to increase profitability, they need to take more risks and lend more. The evidence here suggests that there is credit available, and thus credit cannot be blamed for the crisis. The financial aspects of the crisis looks more and more like a bunch of bad acts by poorly regulated actors which have exploded in all our faces.
