Abstract

Spanish Abstract: El aumento reciente en los niveles de concentración y regulación de los sistemas financieros alrededor del mundo ha revivido el debate sobre la relación entre concentración bancaria, competencia y estabilidad financiera. En este trabajo se analiza la relación entre estas variables para el caso colombiano a partir del uso de diferentes indicadores de concentración y competencia relevantes en la literatura. Los resultados obtenidos confirman la existencia de un fuerte proceso de concentración del mercado bancario durante la última década, que ha estado acompañado a su vez de una disminución en el nivel de competencia entre los participantes. Sin embargo, este proceso no ha comprometido la estabilidad financiera y, por el contrario, ha mejorado. Pese a ello, se evidencia la existencia de una relación no lineal entre estas variables, que sugiere que no es recomendable continuar aumentando los niveles de concentración a futuro.

English Abstract: The recent increase in concentration levels and the regulation of financial systems around the world has revived the debate on the relationship between banking concentration, market competition and financial stability. In this paper, we study the relationship between these variables for the recent Colombian case. Our results confirms the existence of a strong banking concentration process during the last decade, which has been accompanied in turn by a decrease in the level of competition among banks. However, this process has not compromised the stability of the banking system. On the contrary, it has been improved. Finally, we found a non-linear relationship between these variables, suggesting it is not recommended to increase the banking concentration levels in to the future.
