Abstract: We examine whether stress tests distort banks’ risk-taking decisions. We study a model in which a regulator may choose to rescue banks in the event of concurrent bank failures. Our analysis reveals a novel coordination role of stress tests. Disclosure of stress-test results informs banks of the failure likelihood of other banks, which facilitates banks’ coordination in risk-taking. However, conducting stress tests also enables the regulator to more effectively intervene banks, coordinating them preemptively into taking lower risks. We find that, if the social cost of bank failures is very large compared with the social cost of a bailout, stress tests improve welfare, whereas if the cost of bank failures is relatively low, stress tests impair welfare.
