We use high-frequency, geographically granular loan-level data to address an identification problem arising from the changing demand for loans: (1) The data allow for a difference-in-difference specification and for state/time (quarter) fixed effects; (2) we observe banks reduce lending not just in their home states but also outside their home states when their home states hold elections; (3) we observe important cross-sectional differences in the way banks with different characteristics respond to policy uncertainty. Overall, the findings suggest that policy uncertainty has a real effect on residential housing markets through banks' credit supply decisions and that it can spill over across states through lending by banks serving multiple states.
