What are the implications of an aging population for financial stability? To examine this question, we exploit geographic variation in aging across U.S. counties. We establish that banks with higher exposure to aging counties increase loan-to-income ratios, especially where they operate no branches. Laxer lending standards also lead to higher nonperforming loans during downturns, suggesting higher credit risk. Inspecting the mechanism shows that aging drives risk-taking through two contemporaneous channels: deposit inflows due to seniorsâ propensity to save in deposits; and depressed local investment opportunities due to seniorsâ lower credit demand. Banks thus look for riskier clients in no-branch counties.
