The New York Fed recently released a staff report in usual timely fashion, that being after the information is primarily useful, titled Juvenile Delinquent Mortgages: Bad Credit or Bad Economy?
Abstract:
We study early default, defined as serious delinquency or foreclosure in the first year, among nonprime mortgages from the 2001 to 2007 vintages. After documenting a dramatic rise in such defaults and discussing their correlates, we examine two primary explanations: changes in underwriting standards that took place over this period and changes in the economic environment. We find that while credit standards were important in determining the probability of an early default, changes in the economy after 2004—especially a sharp reversal in house price appreciation—were the more critical factor in the increase in default rates. A notable additional result is that despite our rich set of covariates, much of the increase remains unexplained, even in retrospect. Thus, the fact that the credit markets seemed surprised by the rate of early defaults in the 2006 and 2007 nonprime vintages becomes more understandable.
This last sentence struck a match with me. The prevailing thought in economics, financials, mortgages, real estate, etc. is that models can fairly accurately predict future outcomes. A phrase comes to mind; The triumph of financial innovation over common sense.
The ignorance here is the complete disregard for the human element. If you were to follow the pdf that leads to the 38 page paper, you would learn that residential real estate turned into option theory. Here is an exert:
Residential mortgages are complex financial instruments that confer important options on the borrower. The extensive body of previous research on residential mortgage default has adapted option theory to the study of mortgage valuation, since there exist well-developed theory and empirical methods for valuing financial derivatives and their exercise (Black and Scholes 1973).
An important feature of most residential mortgages is that they are “non-recourse” loans, either de jure or de facto. This means that in the event of a default, creditors can sell the house to cover the loan balance, but typically do not legally pursue the borrower for any deficiency.4 This creates a “put” option for the borrower which he/she can exercise if the house value falls sufficiently relative to the loan balance. In addition to this default option, borrowers may continue to make the scheduled payments until the mortgage debt is discharged, or prepay the mortgage either by selling the house and paying off the balance on the mortgage or by refinancing into a new loan (Kau, Keenan, Mueller and Epperson, 1995). The option to prepay is often referred to as the “call” option that borrowers hold when they take out a mortgage.
Just like in 87', the theory misses the big picture, where markets are uniformly using the same models and experience the same problems at the same time from taking on the same risks. This throws the other side of the option out the door when aggregated, prices begin falling and the option to sell is then not available.
So there is the whole, a deep one at that. No scheme can make lending to an unqualified borrower profitable in the long term and the effect is the toppling over of the pyramid that was structured with no anchors.
The fact that credit markets were surprised at all is a testament to the lack of common sense and vision associated with those at the top making decisions, sitting upon their stacks of employee options, just looking to Earn and Burn.
The paper gives greater weight to the economy being the major factor to increased defaults via home price depreciation rather than bad credit underwriting. This paper misses one huge factor though that directly relates to housing price levels; borrowing against equity. This paper cannot explain why such large levels of early defaults starting in 2005 vintages were accounted for.
My own opinion is that price depreciation was just a catalyst. Poor credit underwriting was the rising action. Too much underwriting was the result. This sparked a wave of predictable early defaults. The extra burden of HELOC's made price depreciation that much less manageable for borrowers who were already less than worthy. As stated, home price depreciation was just the catalyst.
There is obviously very little confidence in those running our currency to be had if they cannot connect the dots on this one.
