The financial sector is one of the most important in a country. Its main function is to promote financial brokerage, serving as a bridge between savers and takers. This is essential for a country’s economy to work with efficacy and efficiency. The more robust and solid these organizations are the more credible will a nation’s economic sector be. Mainly because of that its survival is extremely important to a country’s Economy. In Brazil, all the changes that have been occurring in recent years, such as Plano Real, the privatization programs, the deregulation, the openness of the Brazilian market to foreign capital and the national banks’ suitability to the Basel Accords, in the 1990’s, resulted in a change in the Brazilian banking competitive scenario. In addition to that, the US subprime crisis in 2008 exposed great deficiencies of the international financial sector and called its credibility into question. Jointly, there were also several difficulties resulting from the globalization process, like the increase of competitiveness. Therefore, it is exactly in this scenario that a new market is formed, characterized by the escalation of competitiveness between organizations, by more and more demanding consumers, by deregulated markets, and by great technological advance. Taking all these transformations and the importance of a nation’s financial sector into consideration, the aim objective of this study is to analyze the threats and strategically significant opportunities faced by commercial banks in the current competitive landscape of the Brazilian financial sector.
