Efficiency and Contestability in the Colombian Banking System


  • Christian Daude


  • Julien Pascal


Despite progress in the past decade, financial markets in Colombia remain relatively small and shallow. In particular the banking system suffers high intermediation costs, which limit constrains access to finance by households and firms. This paper explores some of the causes behind these intermediation costs. An accounting decomposition of the lending-deposit spread suggests that the levels of contestability and efficiency are low. A more in-depth analysis using stochastic frontier and data envelopment analyses confirm that the efficiency of the Colombian commercial banking system is low compared to other emerging markets and OECD economies with similar levels of development. Furthermore, econometric estimates of market contestability support the hypothesis that contestability in Colombia is subpar. Finally, the paper also explores some of the potential determinants of efficiency and contestability for a sample of the 24 countries over the period 2004 – 2013. This Working Paper relates to the 2014 OECD Economic Survey of Colombia. ( Efficience et contestabilité du marché bancaire en Colombie Malgré les progrès accomplis durant la décennie précédente, les marchés financiers colombiens demeurent peu développés. En particulier, le système bancaire affiche des coûts d’intermédiation élevés qui limitent l’accès financier des ménages et des entreprises. Ce papier explore quelques-uns des déterminants de ces coûts d’intermédiation. Une décomposition comptable de la différence entre les taux d’emprunt et les taux de prêt indique que l’efficience et la contestabilité sont limitées. Une étude approfondie reposant sur les méthodes de frontière stochastique et d’enveloppement des données confirme que l’efficience des banques commerciales colombiennes est faible comparée à d’autres pays émergents et à des pays de l’OCDE ayant le même niveau de développement. Par ailleurs, une estimation économétrique du degré de contestabilité du marché bancaire colombien révèle que celui-ci est bas. Finalement, les déterminants de l’efficience et de la contestabilité sont analysés pour un échantillon de 24 pays sur la période 2004 – 2013. Ce document de travail se rapporte à l’Étude économique 2014 de l’OCDE sur la Colombie (
