Peer Pressure: How do Peer-to-Peer Lenders affect Banks' Cost of Deposits and Liability Structure?

Abstract

This paper shows that banks’ cost of deposits increase following exposure to the Fintech sector. We exploit the exogenous, staggered removal of restrictions on investing through peer-to-peer lending platforms by US states. The entry of Lending Club and Prosper cause the cost of deposits to increase by approximately 11% as banks face more intense competition for deposit funds. Banks’ liability structure also shifts towards greater reliance on non-deposit funding. The findings provide regulatory insights into the unintended consequences, and potentially destabilizing effects, of the nascent Fintech sector on the banking industry.
