Bank one Mauritius

East AfricaFinancial services

Bank One, established in 1997, is a leading bank in trade finance and digital banking technology in Mauritius. It is equally owned by I&M Bank Group of Kenya (which has banking subsidiaries in five countries in Africa), and by CIEL Finance. Through its shareholders, Bank One has a wide reach and access across Africa (over 10 countries).

Our investment

Description of the investment.

This $50 million risk sharing agreement aims to enable Bank One to extend trade finance support to smaller African markets (known as 'Alpha' countries in our strategy, those most in need according to their GDP per capita, fragility measures and poverty gap). This includes countries where we have had limited exposure in the past. It will also support Bank One’s ambition to expand trade finance support in new markets, particularly in West and Central Africa.

Impact information

Applies to investments made from 2019 onwards. The tabs in this section define what we expect to achieve through the investment, assessing the potential impact of the investment against six dimensions of impact. You can find more details on our methodology of assessing impact here.


  • Improved economic opportunities through increased availability of trade finance, including US Dollar liquidity, for businesses (SDG 8.1, 8.5, 8.10, 9.3).

  • Increased access to commodities for businesses and consumer goods and services (SDG 1.4, 2.1).



Economic enabler: Our facility will allow Bank One to extend more trade finance to obligor banks to facilitate the flow of goods to people and companies. This will enable businesses to import the commodities, business inputs and capital equipment they need to sustain business operations, market output and contribute to GDP. Ultimately, this will lead to job preservation and opportunities, and the continued availability of goods and services for consumers.


Stakeholder Geography Characteristics
Firm owners, employees and suppliers

100 per cent 'Alpha' markets

We can assume mass market characteristics across the target countries and given the target markets, there's a strong likelihood that a proportion will be low-income.

How much?

Scale Depth/Duration

We use the scale of the facility and estimated enabled trades as a proxy. Estimated trade enabled by this facility is $81 million per year.

Depth: Depth is difficult to assess but impact is expected to be deeper in a context where the trade conditions have worsened.



Financial additionality: Our contribution is based on Bank One’s need for support to be able to provide trade finance in 'Alpha' markets in Africa, where commercial funding has largely been withdrawn.

Impact score

Impact score (at point of investment)

The Impact Score is a tool to help us manage our performance against our strategic impact objectives. It is designed to incentivise investments that support our productive, sustainable, and inclusive objectives. You can find out more here.

The Impact Score is published for investments made from 2022 onwards. The Impact Scores are calculated at the point of investment. We publish the Impact Scores of new investments annually, once the information has been externally assured by an independent third party.

    We prioritise those sectors that facilitate development and need our capital the most. Our priority sectors contribute towards many of the Sustainable Development Goals.
