Mortgages represent that largest liability most households ever have. We show that interest rate shocks are associated with higher rates of domestic violence in the U.S. We propose two possible mechanisms for this finding. First, higher interest rates lead to mortgage stress for households with adjustable-rate mortgages, triggering conflict and violence. Second, for households with long-term fixed rate mortgages, higher interest rates leads to mortgage lock-in: Households are locked-in to lower rates in their current residence thereby reducing mobility and increasing exposure to abusers. Our findings are economically meaningful and plausibility exogenous under a variety of settings.
