Bank Competition with Financing and Savings Substitutes

Abstract: Abstract This paper models the banking competition in loan and deposit markets on two levels. We measure the competition among different banks and among banks and non-bank financing and saving alternatives. We estimate a model of demand, cost, and market equilibrium equations for differentiated products by using data from the confidential reports that Spanish banks provide to the Bank of Spain during the period from 1988 to 2003. This database contains information on the effective interest rates on new loans and deposits, and the expected loan losses obtained from the Spanish Credit Register. The estimated price elasticities show that the products offered by different banks are close substitutes, which puts pressure on the banks’ profits margins. However, the substitutability between bank and non-bank products is much lower than the substitutability among products offered by different banks. The results also show that Spain’s entrance into the Eurozone did not cause a structural change in the demand and cost conditions of Spanish banks. The banks financed most of the imbalances between bank loans and domestic deposits before the crisis through the interbank market.
