Estimativa do grau de concentração bancária em Mato Grosso : 2017-2021

Abstract

The financial sector was hit with wide changes in the last decades. Concentration in this area was one of those, being determinant to decision making. Thus, the sum of this article was to make an estimate of banking concentration in Mato Grosso in the period of 2017 to 2021 and to evaluate the risks of oligopoly formation if public banks were to be privatized. Data collected from the Central Bank (BACEN) regarding bank branches and their creditors. From that point, the state’s estimate was analyzed through the Herfindahl-Hirschman Index (HHI), using the amount in creditors’ accounts, which resulted in a market with a concentrated tendency in the five years that were evaluated. Public banks are dominant in the state, taking over 73% of the market, and they consist of Banco do Brasil, Caixa Econômica Federal and Banco da Amazônia. Finally, taking into account the privatization of two of the main public banks, there could be a decentralization, considering that CADE determines that private banks can appropriate slices of public ones.
