Exploiting variation in the timing of resets of adjustable rate mortgages (ARMs), we find that a sizable decline in mortgage payments (up to 50%) induces a significant increase in car purchases (up to 35%). This effect is attenuated by voluntary deleveraging. Borrowers with lower incomes and housing wealth have significantly higher marginal propensity to consume. Areas with a larger share of ARMs were more responsive to lower interest rates and saw a relative decline in defaults and an increase in house prices, car purchases, and employment. Household balance sheets and mortgage contract rigidity are important for monetary policy pass-through.
