In other words, Parsons’ premise is exactly wrong: JPM is not paying penalties for mistakes made by Bear Stearns. All that it’s doing is making good on obligations of WaMu and Bear related to securities they sold. And it’s inherent in buying a bank that you become responsible for its liabilities as well as its assets.

There is one unexpected wrinkle to this settlement, however. As Matthew Klein point out, some $4 billion of JP Morgan’s non-fine money will go to the taxpayer all the same, in the form of the FHFA, thanks in large part to the dogged efforts of FHFA director Ed DeMarco. DeMarco has been micromanaging Fannie Mae and Freddie Mac for the past four years, which means that he — rather than Fannie and Freddie themselves — has taken the lead in terms of chasing down money the two agencies are owed by the banks from whom they bought mortgage securities.

DeMarco sits in a kind of weird regulatory limbo: technically he only regulates Fannie and Freddie, but because he’s a fully-empowered government regulator, that gives his lawsuits especial force. And so when he sues JP Morgan (and Citi, and Wells Fargo, and other mortgage-bond merchants), the suits fall somewhere in the middle between aggressive regulatory action and a simple civil claim brought by formerly private companies which suffered losses due to miss-sold securities. Most importantly, because DeMarco is a regulator, other regulators, including most importantly the Justice Department, can join in — and, ultimately, settle the whole deal for a huge headline sum.

The best way of looking at this JPM settlement, then, is not as a massive $13 billion fine for wrongdoing. Rather, you should think of it as an upsized out-of-court settlement between JP Morgan and the various private companies which bought mortgage bonds from JPM, WaMu, and Bear. Those companies were mostly Fannie and Freddie, which means that they’re now owned by the government, and so of course lots of other government baggage is being brought in at the same time. But what we’re not seeing is overreach by the SEC, by the Justice Department, by Treasury, or by any other government agency. And we’re certainly not seeing JPM being punished for takeovers which the government asked it to do. We’re just seeing two enormous and bureaucratic systems — the federal government, and JP Morgan Chase — doing their best to disentangle the various obligations that the latter has to the former. It’s opaque, and not particularly edifying. But it’s probably good, on net, for both parties.
