This study used the DEA-SBM technique to evaluate the efficiency of Brazilian banks in 2014 from the perspective of the three most recurring approaches in this evaluation type: intermediation, production, and profitability. The efficiency scores were evaluated by quintile and the Mann-Whitney test according to (1) capital origin; (2) public vs. private; (3) size; (4) operating segment (5) ratings. The analysis led to ten conclusions and demonstrated that federal public capital banks, micro-sized banks, the banks of the Retail segment (except for the intermediation approach) and AAA-rating banks were the most efficient institutions.
