Traditional theory suggests that higher bank profitability (or franchise value) dissuades bank risk-taking. We highlight an opposite effect: higher profitability loosens bank borrowing constraints. This enables profitable banks to take risk on a larger scale, inducing risk-taking. This effect is more pronounced when bank leverage constraints are looser, or when new investments can be financed with senior funding (such as repos). The model’s predictions are consistent with some notable cross-sectional patterns of bank risk-taking in the run-up to the 2008 crisis.

Using a newly constructed database for 26 countries over 2000-2014, we analyze cross-country and within-country differences in mortgage arrears. We find that restrictive macro-prudential policies, in particular lower regulatory loan-to-value ratios, are significantly associated with a lower share of mortgage arrears in total residential debt. Likewise, better institutions are related with lower delinquency rates, both directly and by enhancing the impact of macro-prudential policies and the right to recourse. We also find that the effect of macro-prudential policies is conditioned by several mortgage market characteristics, such as the maturity of loans, interest rate fixity, and tax deductibility of interest payments.
