This paper shows that by reducing the cyclicality of deposit costs and internal funds (profits), deposit market power reduces banks’ funding risk and provides the flexibility to originate long-term loans. Banks with deposit HHI one standard deviation above average extend loans with about 20% longer maturity than those one standard deviation below average. Deposit market power also allows banks to charge lower maturity premiums. This has real effects: access to banks raising funds in less competitive markets improves growth in bank-dependent borrowers needing long-term finance. Deposit market power, by increasing long-term credit supply, helps alleviate credit cycles.
