Although it is undeniable that information technology (IT) has deeply affected society, its effects are still under scrutiny. This article discusses the impact of IT expenses on the efficiency of the banking sector in Brazil. The novelty of this paper is that it encompasses a segmentation of the banking sector in order to assure that one of the assumptions of the empirical technique is not violated. The sample includes 37 banks that represent 70% of the National Financial System and that are convened into three categories: retailers, wholesalers and specialized in credit. Based on data envelopment analysis technique, the results show that IT expenses have distinct effects on the efficiency of the banking segments. The findings reveal that IT seems to be more influential in the retailing segment than it is in other studied segments
