The Flawed Fundamentals of Failing Banks

Why It Matters

Understanding that weak fundamentals, not just depositor sentiment, cause bank collapses reshapes regulatory priorities and crisis‑management strategies across the financial industry.

Key Takeaways

• Bank failures stem from weak fundamentals, not just panic.
• Historical data (1863‑2024) shows insolvency precedes runs.
• Credit booms in non‑tradeable sectors amplify bank risk.
• Policy focus should shift from liquidity aid to stronger capital standards.

Pulse Analysis

The prevailing narrative that sudden depositor panic triggers bank collapses is being upended by new empirical work from MIT’s Emil Verner. By compiling an unprecedented dataset of U.S. bank performance dating back to the Civil War, Verner demonstrates that most institutions experiencing runs were already insolvent. This pattern holds across multiple crises, from the Great Depression to the 2023 Silicon Valley Bank failure, suggesting that runs are the final symptom of deeper balance‑sheet weaknesses rather than the root cause.

A key insight from Verner’s research is the link between credit expansions in non‑tradeable sectors—such as construction and retail—and subsequent banking distress. When real‑estate‑backed loans surge during booms, banks accumulate high‑risk exposures that can erode capital once valuations fall. This dynamic was evident in historic episodes and modern crises alike, underscoring the importance of monitoring sector‑specific credit growth as an early warning indicator. By applying large‑language models to historic newspaper archives, Verner’s team uncovered over 3,400 bank‑run events, enriching the analytical toolkit for regulators and scholars.

The policy implications are profound. If liquidity injections merely treat the symptom, regulators must prioritize robust capital buffers, rigorous risk‑management frameworks, and proactive supervision of credit booms. Shifting the focus from ad‑hoc emergency funding to preventive measures could reduce the frequency and severity of banking crises. Verner’s findings thus provide a data‑driven foundation for re‑evaluating existing safeguards, encouraging a more resilient banking system that addresses fundamental solvency before panic takes hold.
