Bank Competition and Financial Stability Analysis
Summary
The interplay between bank competition and financial stability sits at the heart of modern banking policy and research. On one hand, vigorous competition can enhance allocative efficiency, improve service quality and drive down financing costs. On the other, excessive rivalry may erode profit margins, reduce capital cushions and encourage moral hazard, potentially undermining systemic resilience. Empirical studies have revealed a non-linear relationship, where moderate competition strengthens stability but extreme contestability can precipitate fragility. Key channels include bank market power, risk-taking incentives, regulatory enforcement and spatial concentration. The influence of digitalisation, cross-border banking and evolving regulatory frameworks has added new dimensions, prompting scholars to re-examine traditional hypotheses such as the competition-stability and competition-fragility views. This strand of analysis carries global significance, guiding policymakers in calibrating competition policy, capital requirements and macroprudential tools to foster a robust yet dynamic banking sector.
