Abstract:

During the 2019–2024 monetary easing cycle, Chinese households used their savings to prepay unprecedented amounts of mortgages. Because refinancing was restricted, mortgage rates remained rigid, while savings returns quickly adjusted to rate cuts. The widening gap between borrowing costs and savings returns encouraged households to deleverage, even reducing consumption in order to prepay more and avoid future interest expenses. Exploiting loan-level data from a major bank, a quasi-natural policy experiment, and UnionPay’s spending records, we provide consistent evidence at both the household and city levels. Our findings suggest that rigid mortgage rates have rendered China’s monetary easing counterproductive.
