Alternatives to Libor in consumer mortgages
Many adjustable rate mortgages in the United States are indexed to Libor. While the accuracy of this rate has recently been called into question, another issue affecting U.S. borrowers has become evident since the onset of the financial crisis. Specifically, many U.S. consumers with Libor-based loans may have been hit with substantially higher payments when their loans reset during the financial crisis than if those loans had been tied to a Treasury rate. We investigate several alternative reference rates for consumer loans and estimate their payment effects on a large sample of Libor-linked ...

Has the housing boom increased mortgage risk?
Payment size, negative equity, and mortgage default
Surprisingly little is known about the importance of mortgage payment size for default, as efforts to measure the treatment effect of rate increases or loan modifications are confounded by borrower selection. We study a sample of hybrid adjustable-rate mortgages that have experienced large rate reductions over the past years and are largely immune to these selection concerns. We show that interest rate changes dramatically affect repayment behavior. Our estimates imply that cutting a borrower?s payment in half reduces his hazard of becoming delinquent by about two-thirds, an effect that is ...
Adjustable-rate mortgages and the Libor surprise
Adjustable-rate mortgages have typically been tied to either of two indexes, one based on U.S. treasuries, the other on the London interbank offered rate, or Libor. The index is used to determine a mortgage?s new interest rate when it is reset, and up until recently, the choice would have made little difference. But since 2007, the rates on which the indexes are based have diverged sharply, and borrowers with Libor-based adjustable-rate mortgages are likely to pay more than they would have had their mortgages been tied to treasuries. Moreover, the proportion of Libor-based ARMs has increased ...
The termination of subprime hybrid and fixed rate mortgages
Adjustable rate and hybrid loans have been a large and important component of subprime lending in the mortgage market. While maintaining the familiar 30-year term the typical adjustable rate loan in subprime is designed as a hybrid of fixed and adjustable characteristics. In its most prevalent form, the first two years are typically fixed and the remaining 28 years adjustable. Perhaps not surprisingly, using a competing risks proportional hazard framework that also accounts for unobserved heterogeneity, hybrid loans are sensitive to rising interest rates and tend to temporarily terminate at ...

Payment changes and default risk: theimpact of refinancing on expected credit losses
This paper analyzes the relationship between changes in borrowers' monthly mortgage payments and future credit performance. This relationship is important for the design of an internal refinance program such as the Home Affordable Refinance Program (HARP). We use a competing risk model to estimate the sensitivity of default risk to downward adjustments of borrowers' monthly mortgage payments for a large sample of prime adjustable-rate mortgages. Applying a 26 percent average monthly payment reduction that we estimate would result from refinancing under HARP, we find that the cumulative ...
