This week's Atlantic column is my somewhat belated response to Judge Jed Rakoff's latest SEC takedown, this time rejecting a proposed settlement with Citigroup over a CDO-squared that the bank's structuring desk created solely so that its trading desk could short it. I think Rakoff has identified the heart of the issue (the SEC's settlements are unlikely to change bank behavior, so what's the point?) but he's really pointing to a problem that someone else is going to have to fix: we need either a stronger SEC or stronger laws. I'd like to see an aggressive, powerful SEC that can deter banks from breaking the law, but we don't have one now.
