Did mortgage securitization cause the mortgage crisis? One popular story goes like this: Banks that originated mortgage loans and then sold them to securitizers didn’t care whether the loans would be repaid. After all, since they sold the loans, they weren’t on the hook for the defaults. Without any “skin in the game” those banks felt free to make worse and worse loans until… kaboom! The story is an appealing one, and since the beginning of the crisis it has gained popularity among academics, journalists, and policymakers. It has even influenced financial reform. The only problem? The story might be wrong.
In this post we report on the latest round in an ongoing academic debate over this issue. We recently released two papers, available here and here, in which we argue that the evidence against securitization that many have found most damning has in fact been misinterpreted. Rather than being a settled issue, we believe securitization’s role in the crisis remains an open and pressing question.
