Competition in Colombian banking : an analysis based on indices of concentration and dominance

Abstract

Este documento analiza la competencia en el sistema financiero colombiano durante el período comprendido entre 2015 y 2023. La medición del grado de la competencia se hace a partir del cálculo del índice de Herfindahl-Hirschman y el umbral de dominancia de Melnik, Shy, y Stenbacka, con base en los datos de la cartera bruta que las entidades reportan a la Superintendencia Financiera. Los resultados arrojan que el sector ha experimentado un aumento en los niveles de concentración y dominancia, en algunos productos de crédito como el microcrédito, el factoring, el crédito rotativo y el leasing, en especial, de forma posterior a las ventas de carteras que se realizaron en los últimos cinco años.This document analyzes the competition in the Colombian financial system during the period from 2015 to 2023. The degree of competition is measured using the Herfindahl-Hirschman Index and the dominance threshold by Melnik, Shy, and Stenbacka, based on the gross loan portfolio data reported by entities to the Financial Superintendence. The results indicate that the sector has experienced an increase in concentration and dominance levels in certain credit products, such as microcredit, factoring, revolving credit, and leasing, particularly following the loan portfolio sales carried out in the last five years.Magíster en EconomíaMaestrí
