We apply the stochastic frontier approach to estimate market-power of Brazilian banks under a multiproduct structure, due to presents flexibility in relation to the required data, in addition to not requiring firms to present income scaling constants. The average markup practiced by Financial Institutions in Credit Operations reduced throughout the period and is greatly impacted by the Inefficiency of Institutions. It was not possible determine a relationship between Credit Risk and the markup applied. Bacen’s participation in the search for greater transparency and competitiveness in the banking sector in the country, the reduction in HHI in the sample period coincides with the efforts of the Bacen to increase competitiveness in the sector. Despite the markup reduction trend observed, Private Banks maintained and Public Banks increased market power. It was found that larger banks and multiproducts have less market power when compared to singular cooperatives and specialized banks. Some Institutions reported losses in credit operations at the same time as obtained net profit with Revenues from other products, which corroborates the argument of the presence of cross subsidies between products. Another important result is that Financial Institutions do not operate in a competitive market, and on average, the markup results in an increase in Bank Profit compared to the that would be expected in Perfect Competitive Markets
