The Bank started its operation in Brazil in 1958, under the name of “Casa Bancária Brazcot Ltda.” In 1960, the former Sumitomo Bank, Limited (“SBL”) acquired 60% of the Bank shareholding control, time at which the Bank became the SBL's second overseas subsidiary, changing its denomination to "Banco Sumitomo Brasileiro S.A.".
Finally, from April 1st, 2001, at the same time that the newly formed Sumitomo Mitsui Banking Corporation (“SMBC”) initiated its activities, as a result of the merger between the Sakura Bank, Limited and Sumitomo Bank, Limited, the Brazilian subsidiary initiated activities with new name, Banco Sumitomo Mitsui Brasileiro S.A.
Since November 27th 2013, "Sumitomo Mitsui Banking Corporation Brasil" is the trade name for Banco Sumitomo Mitsui Brasileiro S/A. The adoption of the trade name aims to demonstrate that "Sumitomo Mitsui Banking Corporation Brasil" operates under the parent company, SMBC which operates globally.
