Deposit market competition, wholesale funding, and bank risk
Abstract
Empirical research on the effect of bank competition on bank risk has so far produced very inconclusive results. In this paper we revisit this long-standing debate and propose a new empirical approach that is concentrated on the relationship between deposit market competition and bank risk. This approach closely follows the traditional theoretical views of the competition and risk relationship and is focused on testing the classical moral hazard problem of the bank: deposit market competition raises the optimal risk choice of the bank by raising the costs of bank liabilities. Since banks can substitute between retail and wholesale funding, we relate deposit market competition to wholesale market conditions and examine their joint effect on the risk of bank assets. The analysis is based on a unique, comprehensive dataset, which combines retail deposit rate data with data on bank characteristics and data on local deposit market features for a sample of 589 US banks. Our results support the notion of a risk-enhancing effect of deposit market competition.
