Established in 2008 through a strategic joint venture between CIEL Finance Limited, the financial arm of the Mauritian conglomerate CIEL Limited, and Kenya-based I&M Group PLC, Bank One Limited (referred to as “Bank One” or the “Bank”) stands as a distinctive player in the Mauritian banking sector.

The Bank boasts a unique position as one of the few local banks with a tangible presence in sub-Saharan Africa (SSA). Bank One is solidified through I&M Group’s extensive reach across Kenya, Tanzania, Rwanda and Uganda, and CIEL Group’s banking operations in Madagascar.

Guided by the vision of establishing itself as Africa’s preferred gateway, Bank One draws strength from a team of seasoned professionals with decades of combined expertise. This adept workforce excels in addressing the unique dynamics of both local and African markets, strategically expanding the Bank’s presence throughout the continent. Covering its main lines of business: International Banking, Private Banking & Wealth Management, Personal Financial Services, Corporate Banking, and Treasury Services, the Bank crafts bespoke products and services tailored for clients both onshore and offshore.

In line with an ambitious digital transformation, Bank One has embarked on key initiatives, including the successful launch of POP in 2021, the first universal digital payment solution in Mauritius, and a comprehensive revamping of its Internet Banking and Mobile Banking platforms. This ongoing digital evolution underscores its commitment to delivering innovative solutions, with several more milestones planned for the short to medium term.

Bank One has deep development finance institution relationships and long-term funding lines in place with the German Investment Corporation (DEG), the International Finance Corporation (IFC) and the French Development Agency (Proparco). Bank One has been rated ‘BB-’ with a Stable Outlook by Fitch Ratings in February 2025.
