Banks Aren't Scared of Rate Hikes: Their Secret Weapon is Deposits!
This paper argues that maturity transformation, traditionally seen as exposing banks to interest rate risk, actually reduces it thanks to the deposit franchise. Banks' market power over deposits lets them offer rates insensitive to market changes, while operational costs are also largely fixed. This creates a natural hedge for long-term lending, stabilizing profits despite interest rate fluctuations.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Reliance on Accounting Measures
The reliance on accounting measures like NIM and ROA might not fully capture economic interest rate risk, as these are backward-looking and based on book values, not market values.
Causality vs. Correlation
While the paper shows correlations, it doesn't definitively prove causality between deposit franchise strength and interest rate risk hedging. Other factors could be at play.
Assumption of Perfect Matching
The model assumes perfect matching of sensitivities, which is unlikely in reality. Examining the magnitude of deviations from perfect matching and their impact would strengthen the analysis.
Limited Scope of Institutions
The study focuses on commercial banks. Expanding the analysis to other financial institutions like credit unions or savings and loans would enhance generalizability.
Rating Explanation
This paper offers a novel perspective on the relationship between maturity transformation and interest rate risk in banks. The empirical analysis is comprehensive and well-executed. However, some limitations regarding causality and model assumptions prevent a perfect score.
