Competition and Contestability in Bank Retail Markets

We examine the role of internet banking in retail-banking competition. The empirical analysis focuses on European banks for the period 2012-15. Building on the idea of contestable markets, we show that internet banking has increased competition through the contestability of markets. The effect is stronger for retail deposits, but recently consumer loans also show an effect. We attribute this finding to the advent of fintechs. These outcomes support the use of non-concentration-based competition measures in banking research.
