Bank Size, Diversification, and Competition: A Study on the Effects of Bank Regulation in SSA

Introduction

A new study has shed light on the impact of bank size, diversification, and competition on the stability of banks in Sub-Saharan Africa (SSA). The research analyzed a sample of 273 commercial banks from 25 SSA countries over the period 2009-2018.

Key Findings

• Larger banks tend to be more stable, as measured by their solvency risk (Z-score) and liquidity risk (liquidity ratio).
• Income diversification is positively associated with bank stability.
• Increased competition is negatively associated with bank stability.

Methodology

The researchers used a dynamic panel model to estimate the relationships between bank characteristics and stability, controlling for year dummies, macroeconomic variables, and institutional legal framework variables. They found that the lagged dependent variables were positive and statistically significant, indicating persistence in risk-taking behavior.

Implications for Policymakers

The study’s findings have important implications for policymakers seeking to promote financial stability in SSA. The results suggest that regulators should focus on promoting bank size and diversification, while also ensuring that competition is balanced with prudential regulations to mitigate excessive risk-taking.

Recommendations

• Regulators should prioritize promoting bank size and diversification.
• Ensure that competition is balanced with prudential regulations to mitigate excessive risk-taking.

Conclusion

The study’s findings highlight the importance of considering bank size, diversification, and competition when designing policies aimed at promoting financial stability in SSA. By taking these factors into account, policymakers can better support the development of a robust banking sector and promote economic growth in the region.

Key Takeaways

• Larger banks tend to be more stable, conditional on the level of regulation.
• Income diversification is positively associated with bank stability.
• Increased competition is negatively associated with bank stability.
• Regulators should focus on promoting bank size and diversification while balancing competition with prudential regulations.
