La relation entre le taux des crédits et le coût des ressources bancaires. Modélisation et estimation sur données individuelles de banques

In this paper, we first derive a theoretical model in which bank loans rates are assumed to be determined by the cost of loans (re)financing. We consider that imperfect competition prevails on the credit market and that banks determine the (re-)financing structure of the loans they grant by maximizing their profit, taking account of the loans demand elasticity. This model is then estimated using a panel of French banks. The estimation results indicate that banks get the necessary resources to refinance their loans, by decreasing importance, from the monetary market, from the financial market and from interest-bearings deposits. An increase of one point in the monetary base rate is shown to have an impact of about 0.8 point on banks loans rate.
