The Effect of Safe Assets on Financial Fragility in a Bank-Run Model
Risk-averse investors induce competitive intermediaries to hold safe assets, thereby lowering the probability of a run and reducing financial fragility. We revisit Goldstein and Pauzner (2005), who obtain a unique equilibrium in the banking model of Diamond and Dybvig (1983) by introducing risky investment and noisy private signals. We show that, in the optimal demand-deposit contract subject to sequential service, banks hold safe assets to insure investors against investment risk. Consequently, fewer investors withdraw prematurely, which reduces the probability of a bank run. Safe asset ...

Opinion: Why Do Bank Runs Happen?
The first half of 2023 has reminded us once again that banks are not immune from failure. In early March, Silicon Valley Bank (SVB) suffered a run on deposits and quickly collapsed. Its closure was followed by the failure of Signature Bank, a smaller bank, two days later. And even more recently, regulators exerted considerable effort to arrange the sale of First Republic Bank to a larger bank. The Fed was responsible for supervising and regulating SVB, and it recently issued its report examining what went wrong. I encourage you to take a look.

How (Un-)Informed Are Depositors in a Banking Panic? A Lesson from History
How informed or uninformed are bank depositors in a banking crisis? Can depositors anticipate which banks will fail? Understanding the behavior of depositors in financial crises is key to evaluating the policy measures, such as deposit insurance, designed to prevent them. But this is difficult in modern settings. The fact that bank runs are rare and deposit insurance universal implies that it is rare to be able to observe how depositors would behave in absence of the policy. Hence, as empiricists, we are lacking the counterfactual of depositor behavior during a run that is undistorted by the ...

Why Do Banks Fail? Three Facts About Failing Banks
Why do banks fail? In a new working paper, we study more than 5,000 bank failures in the U.S. from 1865 to the present to understand whether failures are primarily caused by bank runs or by deteriorating solvency. In this first of three posts, we document that failing banks are characterized by rising asset losses, deteriorating solvency, and an increasing reliance on expensive noncore funding. Further, we find that problems in failing banks are often the consequence of rapid asset growth in the preceding decade.

What makes large bank failures so messy and what should be done about it?
This study argues that the defining feature of large and complex banks that makes their failures messy is their reliance on runnable financial liabilities. These liabilities confer liquidity or money-like services that may be impaired or destroyed in bankruptcy. To make large bank failures more orderly, the authors recommend that systemically important bank holding companies be required to issue ?bail-in-able? long-term debt that converts to equity in resolution. This reassures holders of uninsured liabilities that their claims will be honored in resolution, making them less likely to run. In ...

Why Do Banks Fail? The Predictability of Bank Failures
Can bank failures be predicted before they happen? In a previous post, we established three facts about failing banks that indicated that failing banks experience deteriorating fundamentals many years ahead of their failure and across a broad range of institutional settings. In this post, we document that bank failures are remarkably predictable based on simple accounting metrics from publicly available financial statements that measure a bank’s insolvency risk and funding vulnerabilities.

Banking System Vulnerability: 2022 Update
To assess the vulnerability of the U.S. financial system, it is important to monitor leverage and funding risks—both individually and in tandem. In this post, we provide an update of four analytical models aimed at capturing different aspects of banking system vulnerability with data through 2022:Q2, assessing how these vulnerabilities have changed since last year. The four models were introduced in a Liberty Street Economics post in 2018 and have been updated annually since then.

Short Selling and Bank Deposit Flows
Some observers have argued that the short selling of bank stock contributes to bank runs and bank failures. Previously, no evidence has been available. We find no evidence that more short selling of bank stock is associated with materially larger outflows of bank deposits. We believe this means that proposals to restrict the short selling of bank stock should be supported by other arguments.

Preventing bank runs
Diamond and Dybvig (1983) is commonly understood as providing a formal rationale for the existence of bank-run equilibria. It has never been clear, however, whether bank-run equilibria in this framework are a natural byproduct of the economic environment or an artifact of suboptimal contractual arrangements. In the class of direct mechanisms, Peck and Shell (2003) demonstrate that bank-run equilibria can exist under an optimal contractual arrangement. The difficulty of preventing runs within this class of mechanism is that banks cannot identify whether withdrawals are being driven by ...
