内容記述
We examine how the CCB affects mortgage pricing after Switzerland was first to activate this macroprudential tool of Basel III. Observing multiple offers per request, we obtain three core findings. First, the CCB changes the composition of mortgage supply, as capital-constrained and mortgage-specialized banks raise prices relatively more. Second, risk-weighting schemes do not amplify the CCB effect. Third, CCB-subjected banks and CCB-exempt insurers both raise mortgage rates. To conclude, changes in the supply composition hint at the CCB’s success in shifting mortgages from less to more resilient banks, but stricter capital requirements do not discourage banks from risky mortgage lending.
