Using two-step dynamic system, the generalized method of moments the study shows that while public sector-led financial sector transparency reduces bank market power, private sector-led financial sector transparency promotes bank market power, given that private sector-led transparency gives financially sound banks an advantage in solidifying market power and dominance. Similarly, while financial crises reduce the market power of banks, implying that during financial crises, banks lose their market power, financial sector transparency promotes the negative effect of financial crises on bank market power. This implies that during financial crises, financial sector transparency, whether enforced through private or public sector, boosts the weakening effect of financial crises on bank market power. These findings imply that regulators can rely on financial transparency to tame bank market power and enhance banking competitiveness. The findings and results are consistent even when country, time and continental effects are controlled for.enbankmarket powerprivate sectorArticle
