The Impact of Crisis-Period Interest Rate Declines on Distressed Borrowers.

The article investigates the causal impact of reductions in benchmark interest rates, specifically the 6-month London Interbank Offered Rate (LIBOR), on the renegotiation and performance of distressed subprime adjustable-rate mortgages (ARMs) from the 2000s housing crisis. Using a two-stage least squares (2SLS) instrumental variable approach that exploits variation in the timing of LIBOR measurement before mortgage payment resets, the study finds that declines in LIBOR significantly increased the probability of loan modifications, lowered borrowers' monthly mortgage payments by about $480 on average, and reduced short- to medium-term foreclosure rates. However, these benefits were partially offset by borrowers who remained delinquent after modification, limiting longer-run improvements in loan performance. The findings also highlight heterogeneity in modification outcomes, with real estate investors and less risky borrowers more likely to renegotiate, while labor market conditions influenced the durability of modification benefits, suggesting that monetary easing alone may not fully resolve borrower distress without complementary macroeconomic support.
