We examine the consequences of a sudden increase in household debt burdens by exploiting variation in exposure to household foreign currency debt during Hungary's late-2008 currency crisis. The revaluation of debt burdens causes higher default rates and a collapse in spending. These responses lead to a worse local recession, driven by a decline in local demand, and negative spillover effects on nearby borrowers without foreign currency debt. The estimates translate into an output multiplier on higher debt service of 1.67. The impact of debt revaluation is particularly severe when foreign currency debt is concentrated on household, rather than firm, balance sheets.
