An update of the Brazilian data economy in open research and consumption in the Brazilian economy B3. The study of the input-oriented Banks, Charnes and Cooper model (BCC-I), cross-efficiency and super-efficiency to evaluate the performance of the banks under study. Input and output data were analyzed using RStudio2021.09.2 software. Of the 63 Decision Tone Units (DMUs) only 6 were efficient, but the B1918 DMU was more efficient.
