The single best explanation for why we had a terrifying financial crisis 10 years ago goes back to how easy it seems to be to take risks when it's someone else's money.
It's a problem often called moral hazard, a term that was talked about a lot just after the financial crisis but not as much lately. Now, 10 years out from the worst days of the financial crisis, it's important to stress once again that this is a chronic problem. And it's not something easily fixed with a batch of regulations.
To get the idea, just imagine what would happen if you had to decide how much risk to take while fully aware that somebody else would bear the losses if things don't pan out. Sounds a little like "heads I win, tails you lose."
Lots of Americans during and after the financial crisis hated the idea of the federal government propping up private financial firms, and this was one reason why. These companies wounded themselves by taking risks in housing and mortgage finance and if the taxpayers saved them, the argument went, they would just try it again.
The government had to really step up its support after the investment bank Lehman Brothers collapsed 10 years ago this weekend, precipitating the scariest week of the crisis.
Maybe the federal government got this one at least partly right by dodging moral hazard and letting Lehman tip over. Yet a version of the moral hazard problem existed in spades at Lehman, and it proved fatal — to the company. And it was happening all along the housing finance chain.
In the mortgage origination business, it wasn't the mortgage banker's money. So what mattered was not whether it was a good mortgage but whether the deal closed.
If the mortgage-backed securities put together by investment banks later turned out to have been backed by some slices of the worst mortgages, the bankers who packaged and sold the deal still kept their bonuses.
