MORTGAGES, MARKETS AND WHAT WE KNOW SO FARDetroit Chapter of the Institute of Internal Auditors Robert Van Order University of Michigan
Subprime ARM Defaults are Very Different from Prime and Subprime FRM – Recession Loans 90 days or more delinquent or in foreclosure (percent of number) Subprime ARM Subprime FRM FHA & VA Prime Conventional Source: Mortgage Bankers Association (Quarterly data not seasonally adjusted;1998Q1-2007Q3)
Stylized Facts and Gatherings from Various Data Sources • Credit Risk: A Few Propositions • Recent History: Especially Large Early Payment Defaults: Can it be rate adjustments? • Changing Loan Characteristics: Hard vs. Soft Data, Technical Change and the Two Decades. • Economic Conditions • Market Structure: The rise of subprime • Securitization: The rise of non-agency securities
2002 2003 2004 2005 2006 2007 Cumulative REO Rates Are Showing Poor Performance of Recent Origination VintagesCould it have been ARMs? Alt-A Subprime Cumulative REO Rate as a Share of Number of Loans Originated Age of Loan in Number of Months From Origination Date Source: Loan Performance, a subsidiary of First American Real Estate Solutions Note: the last twelve points on each origination year cohort contain fewer loans progressively as loans issued at earlier dates always age faster. Data through December 2008.
Credit Risk • Underwriting models and history suggested scorecards and diversification worked
Relative Default ProbabilitiesNote the “Nonlinearity” as you move NortheastMore sensitive to mistakes.
So looking back, you would have thought that controlling FICO and LTV was a big deal, you couldn’t have a credit problem without changes in FICO-LTV distribution, and a diversified portfolio would perform well. • But Performance Got Really Bad. • Especially in Early Months
Underwriting has changed over time, but not in ways you might have thought.
We Seem To Have Two Explanations Left • Economic Conditions. • Structure and Moral Hazard

The structure of the Market Has Changed • More Subprime and Alt-A • Non Agency Securitization
Subprime used to be about 10% of originations, but it’s share increased a lot after 2003
Securitization ChangesNote the nonagency share went up after the subprime share went up and around the time the vintages got worse.
SUBPRIME SECURITIZATION Credit risk is more important than for Agency securities. The risk has been handled (poorly) by structuring. So securitization could have been a big part of the problem, because it is so susceptible of moral hazard/asymmetric information. Recall that to some extent the recent subprime loans didn’t look that bad on paper. Hard vs. soft information.

As an aside there have been spillovers that don’t match with actual risk.
