Provisioning Rules and Bank Lending : A Theoretical Model

This paper develops a partial equilibrium model of a banking firm to analyze how provisioning rules influence loan market fluctuations. We show that a backward-looking provisioning system amplifies the pro-cyclicality of loan market fluctuations. We demonstrate that, in a forward-looking provisioning system where statistical provisions are used to smooth the evolution of total loan loss provisions, the issue of pro-cyclicality of loan market fluctuations does not exist. Our results support the recent call of the Basel Committee for the implementation of a forward-looking provisioning system to address procyclicality
