The Brazilian banking network is being reached by the increasingly global changes. Data Envelopment Analysis was applied to measure the competition level through corporate performance among Brazilian banks. We used data about total owner capital, liability, total revenue, and semester output of 144 banks. Banks were divided into three groups: big, medium, and small-sized banks. BCG matrix approach was used to classify the several operational efficiency and profitability indicators. The results show big banks have the best performance and small banks the worst performance.
