Abstract

Context: the financial market has experienced sharp restructuring and mergers in recent decades. As banks expand the scope of their activities, they raise concerns about the impact on the sector's competitiveness. If the characteristics of the financial industry, which contribute to make the sector more concentrated, can make it less competitive, it implies assessing the relationship between concentration and competition. Objective: the general objective of this study is to promote diagnosis of the organization of the national credit market by calculating and analyzing concentration and competition indicators, between 2000 and 2019. Methods: to measure concentration, the Herfindahl-Hirschman and the Five Major Concentration Ratio indexes are used. The degree of competition is estimated via Lerner's econometric model applied to data displayed on a panel with accounting and financial information from financial institutions. Results: the results suggest that although the concentration has increased in the time frame considered, competitiveness has not deteriorated, reinforcing the argument of seminal references that concentration does not necessarily harm competition. Conclusion: in the absence of academic consensus, this work elucidates the relationship between concentration and competitiveness. Still, it gains relevance by pointing out the role of regulation and credit unions in increasing recent competition. The work thus becomes capable of supporting policies that promote contestability, such as initiatives that relax restrictions on the entry of non-banking institutions and financial technology companies.
