Okay, it’s the closest he’s come to admitting he did it:

The Crisis, by Alan Greenspan. It sounds like an airport novel. But the 66-page paper is the closest we’ve ever gotten to a mea culpa from the former Fed chief, who chaired the US central bank in the midst of a growing housing bubble.

And he talks about how he regrets a lot of things. The rise of megabanks, trivial capital requirements, lack of supervision, knowing about subprime mortgage slime and ignoring it. But he doesn’t go so far as to say he regrets the Fed’s low interest rates, without which very little of the risk-taking he so much regrets not intervening in would have ever happened. It’s hard out there for a vilified ex-Fed chair, we guess. But, at this point, what does he have to lose by admitting it?
