Last updated August 31, 2026
Overview
Bank One Mauritius is a full-service commercial bank headquartered in Port Louis, Mauritius. Its business combines domestic banking with cross-border services oriented toward Sub-Saharan Africa. Within Mauritius, the bank serves retail and corporate customers through a branch network that includes its main branch in Port Louis and branches in Curepipe, Rose Hill, Rose Belle, Vacoas, Quatre Bornes, and Flacq. Its broader service scope includes wealth management, private banking, custody, and banking for corporate and financial-institution clients. The bank is jointly owned by CIEL Finance Limited and I&M Group PLC. CIEL Finance is associated with CIEL, a diversified Mauritian group with activities across multiple countries, while I&M Group has banking and other commercial interests in East and wider Sub-Saharan Africa. The ownership structure gives Bank One access to shareholder networks and market knowledge spanning several African banking markets. According to the referenced Wikipedia material, the bank's shareholders have banking interests in Kenya, Madagascar, Rwanda, Tanzania, Uganda, Ghana, Côte d'Ivoire, and Mauritius. Bank One's operating model therefore combines a domestic universal-bank proposition with regional and international capabilities. Its domestic activities address everyday personal and business banking needs, while its cross-border focus supports companies, financial institutions, investors, and internationally connected customers using Mauritius as a financial and business hub. The bank also provides specialized services for higher-value clients through private banking and wealth-management offerings, and institutional infrastructure through custody services. The institution is privately held rather than exchange-listed. The referenced material reports a staff of 421 employees and describes the bank as operating in Mauritius with cross-border business focused on Sub-Saharan Africa. No reliable source in the supplied material establishes the bank's founding year, original founder, official website, current chief executive, or detailed financial results. Those fields are consequently left unspecified.
History
Bank One Mauritius is described in the available reference material as a full-service commercial bank based in Mauritius. The supplied sources do not state a founding date or provide a detailed chronology of the institution's creation, rebranding, or early operations. What is clear is that the bank developed as a privately owned Mauritian banking institution with both domestic and regional ambitions. Its domestic platform is centered on Mauritius. The bank maintains a branch network serving major population and commercial centers, with the main branch located on Sir William Newton Street in Port Louis and additional branches in Curepipe, Rose Hill, Rose Belle, Vacoas, Quatre Bornes, and Flacq. This network supports its retail and corporate banking activities and gives the institution a physical presence beyond the capital. Bank One's business scope extends beyond conventional branch banking. The available description identifies wealth management, custody, private banking, corporate banking, and services for financial institutions among its principal segments. It also conducts cross-border business focused on Sub-Saharan Africa. This regional orientation reflects the commercial and financial links of Mauritius with African markets and the wider role of the country as an international business and financial-services center. The bank is jointly owned by CIEL Finance Limited and I&M Group PLC. CIEL Finance is linked to the CIEL group, a large Mauritian business group with operations in multiple countries. I&M Group is an African financial and commercial group with interests that include banking, insurance, manufacturing, and real estate, and operations in Kenya, Tanzania, Uganda, Rwanda, and Mauritius. The shareholder groups' wider African presence provides Bank One with a regional network relevant to corporate, institutional, and cross-border customers. The supplied reference material reports that Bank One has 421 staff and serves domestic and international customer segments. It characterizes the bank's shareholders as having banking operations in eight African markets: Kenya, Madagascar, Rwanda, Tanzania, Uganda, Ghana, Côte d'Ivoire, and Mauritius. This network is presented as an important source of regional access and market understanding for the bank's cross-border proposition. Bank One remains privately owned rather than publicly listed. The available materials do not provide sufficient information to document specific leadership changes, acquisitions, product launches, advertising campaigns, controversies, regulatory actions, or financial-performance milestones. Accordingly, the historical record in this dossier focuses on the bank's documented ownership, geographic footprint, service mix, and regional positioning rather than adding unsupported events.
