Bank Failures: The Roles of Solvency and Liquidity
Key Points:
- Bank failures in the U.S. are primarily caused by weak bank fundamentals such as poor asset quality, declining income, and inadequate capitalization, rather than sudden liquidity crises or runs alone.
- Recovery rates from failed banks indicate that most were fundamentally insolvent before failure, with runs often serving as a trigger rather than the root cause.
- Historical bank examiner reports consistently attribute failures to poor asset quality and economic conditions, rarely citing runs or liquidity issues as primary causes.
- Strong banks typically survive runs through mechanisms like owner support, interbank lending, clearinghouse liquidity, and temporary suspension of convertibility, preventing solvent banks from failing due to runs.
- Policy implications emphasize the importance of deposit insurance, lender-of-last-resort facilities, higher equity capital requirements, and effective supervision to enhance banking system resilience and prevent failures driven by insolvency.
