“Amortization Requirements, Distortions, and Household Resilience: Problems of Macroprudential Policy II,” June 2019, paper.
Mortgage lending standards have tightened in Sweden in recent years, in particular through mandatory amortization requirements introduced by the Swedish FSA. The stated purpose is to increase the resilience of mortgagors to shocks, but it is shown that the resilience actually falls and that the tightening causes or worsens many distortions. Households without high income or wealth face higher barriers to entry into owner-occupancy. The mobility within the market for owner-occupied housing is reduced. First-time buyers without high income or wealth are excluded from the owner-occupancy market in Stockholm Municipality and many outsiders have to resort to a high-rent secondary-rental market. To prevent such exclusions, housing prices may have to fall by almost 40%. Less-than-high-income outsiders have higher housing user cost than high-income insiders. A less wealthy outsider has a higher user cost than a high-wealth insider with similar income. Mortgagors are forced to oversave and underconsume relative to their disposable income, and their consumption becomes more sensitive to income shocks. They have to save in illiquid housing equity instead of more liquid and diversified assets. They become less resilient to shocks for many years, for a very small gain in resilience later. Secondary-rental outsiders are forced to overpay, undersave, and underconsume, and their consumption becomes more sensitive to income shocks. They face less resilient to shocks, without any gain in resilience later. By design the amortization requirements make the amortization countercyclical, which makes consumption more procyclical and sensitive to income shocks. The tightening of lending standards reduces demand for and lowers the prices of housing. This in turn reduces already too-low housing construction and worsens the structural problem of excess demand for housing. The conclusion is that this example of macroprudential policy is counterproductive and harmful to social welfare and equity.
