- Date: January 11, 2019

- DOI: https://doi.org/10.5089/9781484390078.001

### Research objective and approach
- Analyze how bank profitability impacts financial stability from theoretical and empirical perspectives.
- Theoretical component: develop a model exploring the role of non-interest income and retail-oriented business models in the profitability–stability relationship.
- Empirical component: panel regression analysis of empirical determinants of bank risks and profitability for 431 publicly traded banks (U.S., advanced Europe, and GSIBs) from 2004 to 2017.

### Key empirical findings
- Profitability is negatively associated with:
  - a bank’s contribution to systemic risk.
  - a bank’s idiosyncratic risk.
- Over-reliance on the following is associated with higher risks:
  - non-interest income (market-based NII activity)
  - wholesale funding
  - leverage
- Low competition is associated with:
  - low idiosyncratic risk
  - high contribution to systemic risk
- Key factors that influence bank profitability:
  - the problem loans ratio
  - the cost-to-income ratio

### Policy implications and recommendations
- Policy makers should better understand the source of bank profitability, with particular attention to instances of over-reliance on:
  - market-based non-interest income
  - leverage
  - wholesale funding
