Initially founded in 1981 as the Island Development Bank (IDB), the financial organisation had several changes throughout time. On 13 January 1993, it was renamed the Islamic Bank of Brunei (IBB) and relocated to its current multi-million dollar building, while the Development Bank of Brunei (DBB) was established in 1995. Afterwards, DBB changed its name to the Islamic Development Bank of Brunei (IDBB) in 2001. In 2005, IBB and IDBB underwent a crucial merger that led to the establishment of Bank Islam Brunei Darussalam (BIBD).
Sultan Hassanal Bolkiah inaugurated the Dar Takaful IBB Utama and Dar Takaful IBB2 buildings in Bandar Seri Begawan earlier on 5 May 2003. After Fajr Capital obtained 29% stake BIBD in 2010, the bank underwent a transformation that culminated in the 2013 rebranding initiative. BIBD has achieved several noteworthy milestones, such as receiving an A− rating from
S&P Global Ratings in 2015, introducing BIBD NEXGEN in 2018, and obtaining ISO 9001
Bureau Veritas Certification in 2019. In order to unify business operations and planning throughout the whole organisation, global enterprise software expert
Ramco Systems announced the effective launch of its
Enterprise Resource Planning (ERP) suite at BIBD in 2018. As part of the bank's mobile payment strategy, BIBD chose the
Rambus Token Service Provider (TSP) in 2019 to let its clients to conduct safe transactions. In January 2020, Fajr sold its shares to the BIA, so achieving full Bruneian ownership of the bank. The BIBD Sustainability Leaders Awards will be introduced in 2023, according to BIBD, to honor and recognize young people in Brunei who are working to create a more sustainable future. The bank has a long-standing history of supporting the government in achieving
Wawasan Brunei 2035, both through its business practices as well as the bank's community-based initiatives such as BIBD Special Entrepreneurial Empowerment and Development Scheme (SEED) and BIBD ALAF. BIBD has also been a strong supporter of the development of local micro,
small and medium enterprises (MSMEs) through its SME360 service. == Senior leadership ==
