Crédit et capital réglementaire : l’exigence est-elle contraignante ?

This paper examines the sensitivity of non-financial corporate lending to banks' capital ratio and their supervisory capital requirements. We use a unique database for the French banking sector between 2003 and 2011 combining confidential bank-level Bank Lending Survey answers with the discretionary capital requirements set by the supervisory authority. We find that on average, more capital means an acceleration of credit. But the elasticity of lending to capital depends on the intensity of the supervisory capital constraint. More supervisory capital-constrained banks tend to have a credit growth that is less sensitive to the capital ratio. Our results also show a similar effect for non-performing loans. When banks are constrained, credit growth is all the more sensitive to this type of assets as their share rises. However, both aforementioned effects weaken close to the supervisory minimum capital requirement.
