Abstract
Abstract We characterize the interaction between banks’ liquid assets purchases and deposit issuance decisions. Using global games, we derive a liquidity multiplier: the amount of deposits a bank can create when endowed with one additional unit of liquid asset to maintain a given level of liquidity risk. In our central theorem, we prove it is larger than unity. This entails that banks have a special role in enhancing liquidity provision, “multiplying” liquid assets into a larger quantity of deposits. Our theory has implications for banks’ balance sheet choices, the pricing of liquid securities, and the role of public liquidity provision.

The Review of Financial Studies is a prominent platform that aims to foster and widely distribute noteworthy research in financial economics. With an expansive editorial board, the Review strives to maintain a balance between theoretical and empirical contributions. The primary focus of paper selection is based on the quality and significance of the research to the field of finance, rather than its level of technical complexity. The scope of finance within the Review encompasses its intersection with economics. Sponsoring The Society for Financial Studies, the Review and the Society appoint editors and officers through limited terms.
