We identify exposure to political risk by exploiting a unique variation around land lease extension protection after 2047 in Hong Kong’s housing market due to historical arrangements. Relative to properties that have been promised an extension protection, those with unprotected leases granted by the current government are sold at a discount of 8 percent; those with colonial leases suffer an additional discount of 8 percent. Incorporating estimated structural parameters that suggest an additional 20 percent ground rent after 2047, our model matches empirical discounts well across lease horizons. Discounts increase over time, particularly in areas with greater pessimism about the city’s future.

Exploiting variation in the timing of resets of adjustable-rate mortgages (ARMs), we find that a sizable decline in mortgage payments (up to 50 percent) induces a significant increase in car purchases (up to 35 percent). 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.
