In addition to revamping existing rules for bank capital, Basel III introduces a new global framework for liquidity regulation. One part of this framework is the liquidity coverage ratio (LCR), which requires banks to hold sufficient high-quality liquid assets to survive a 30-day period of...

We study a finite-depositor version of the Diamond-Dybvig model of financial intermediation in which the bank and all depositors observe withdrawals as they occur. We derive the constrained efficient allocation of resources in closed form and show that this allocation provides liquidity...

We study how the introduction of a central bank digital currency (CBDC) would affect the stability of the banking system. We present a model that captures a concern commonly raised in policy discussions: the option to hold CBDC can increase the incentive for depositors to run on weak banks. Our...

The buildup of reserves in the U.S. banking system during the financial crisis has fueled concerns that the Federal Reserve's policies may have failed to stimulate the flow of credit in the economy: Banks, it appears, are amassing funds rather than lending them out. However, a careful...

We study the effects of the new Basel III liquidity regulations in jurisdictions with a limited supply of high-quality liquid assets. Using a model based on Bech and Keister (2013), we show how introducing a liquidity coverage ratio in such settings can have significant side effects, leading to...

We study the role of commitment in a version of the Diamond-Dybvig model with no aggregate uncertainty. As is well known, the banking authority can eliminate the possibility of a bank run by committing to suspend payments to depositors if a run were to start. We show, however, that in an...

Self-fulfilling expectations are commonly believed to play an important role in the transmission of currency crises across countries. However, existing models that use multiple equilibria to illustrate the importance of such expectations have many undesirable features. This paper presents a new...
