In this undergoing project, we explore how a doubling of capital requirements affect lending. To do so, we use an extract of the credit registry in Tunisia, and study how this policy change has affected bank lending. Capital constrained banks react differently than unconstrained banks, and we will investigate possible effects on risky lending. Future work remains to be done, in particular regarding how public banks behave vs private ones, and a more granular look at the risk taking across different sectors.
