Competition and relationship lending: Friends or foes?

Recent empirical findings by Elsas, 2005 and Degryse and Ongena, 2007 document a U-shaped effect of market concentration on relationship lending which cannot be easily accommodated by the investment and strategic theories of bank lending orientation. In this paper, we suggest that this non-monotonicity can be explained by looking at the organizational structure of local credit markets. We provide evidence that marginal increases in interbank competition are detrimental to relationship lending in markets where large and out-of-market banks are predominant. By contrast, where relational lending technologies are already widely in use in the market by a large group of small mutual banks, an increase in competition may drive banks to further cultivate their extensive ties with customers.
