Thus, we examined the relationship between concentration indicators (C3 and HHI), competition (H-statistic) and risk (NPL, Z-score) for the period comprehended between 2001 and 2013. The relationship between non-performing loans (NPL), concentration and competition was empirically tested using panel data models. The results indicates that bank concentration has a significant impact on the NPL, suggesting that more concentrated systems are more fragile. On the other hand, the results for competition and NPL indicates that a more competitive environment may generate a more stable financial system. / O presente trabalho analisou em que medida a estrutura de mercado da indústria bancária brasileira – em níveis de concentração e competição – afeta o apetite ao risco de seus agentes. Para tanto, o estudo examinou a relação entre indicadores de concentração (C3 e HHI), competição (Estatística-H) e de risco (NPL, Z-score) para o período entre 2001 e 2013. A relação entre non-performing loans (NPL), concentração e competição foi empiricamente testada através de modelos de dados em painel. Os resultados indicam que a concentração bancária tem impacto significativo no NPL, sugerindo que sistemas mais concentrados são mais frágeis. Por outro lado, os resultados para competição e NPL indicam que em ambientes mais competitivos podem gerar sistemas financeiros menos instáveis.
