History
BSI originated from three state-owned banks which are subsidiary of larger banks: BRIsyariah (of Bank Rakyat Indonesia/BRI), Bank Syariah Mandiri (of Bank Mandiri) and BNI Syariah (of Bank Negara Indonesia/BNI).
 * Bank Syariah Mandiri: The bank was founded in 1955 as Bank Industri Nasional ("National Industrial Bank"); in 1967 it was changed into Bank Maritim Indonesia ("Maritime Bank of Indonesia") and was changed again in 1973 into Bank Susila Bakti. In 1999, the newly founded Bank Mandiri became majority shareholder of the bank, and was converted to sharia banking in 1999 as Bank Syariah Mandiri.
 * BNI Syariah: The bank was founded on 29 April 2000 as a sharia banking unit of BNI. In 2010, it spun-off as a separate subsidiary.
 * BRIsyariah: The bank was originally established on 3 July 1969 as Bank Djasa Arta (later spelled Bank Jasa Arta) and headquartered in Bandung, West Java. On 19 December 2007, the bank was acquired by BRI. Following Bank Indonesia permit on 16 October 2008, it was converted to sharia banking and officially operated as BRI Syariah on 17 November 2008; in 2009 the sharia banking unit of BRI was officially merged to the bank. In 2018, the bank went public in Indonesian Stock Exchange.
