This study aimed to analyze how the evolution of the regulatory institutional capital market environment has influenced the business development in Brazil. The research sought to understand the historical development of the market, how their institutions were built, and the effects of regulation on the governance structures of companies through the historical method of investigation. The analysis led to the result that the provisions imposed by the institutional environment were determinants in market performance over time. In their origins, the institutions represented obstacles to economic activity, resulting in the delay of the capital market consolidation. However, when the market’s regulatory environment was created, it has become an alternative to companies for transaction cost savings. Therefore, with the implementation of corporate governance as transparency mechanism, the improvement of management is characterized as the development of the Brazilian business scenario.
