Household savings and mortgage decisions : the role of the "downpayment channel" in the euro area

This paper analyses the interactions between household wealth, mortgage decisions and savings in a single empirical framework and identifies an important role for a "down-payment channel" in the euro area. Contrary to the traditional housing wealth channel, the "down-payment channel" posits a positive relation between household savings and house prices: a rise in house prices forces credit-constrained households who wish to acquire a house to accumulate more savings in order to cover a higher down-payment (i.e. the share of the housing acquisition value that is not covered by a mortgage). The overall effect of a rise in house prices on private consumption can be seen as the result of two offsetting forces: a rise in house prices tends to push up consumption via the traditional housing wealth channel but it also tends to depress the consumption of credit-constrained households who wish to acquire a house via the down-payment channel. Estimates based on a structural VEC model for the euro area suggest that the down-payment effect tends to dominate in the medium term, translating into an overall negative impact of higher house prices on consumption in the euro area.
