Values & Approach

Being conscious of our responsibility as a lender in the microfinance sphere, we put significant efforts in treating our clients fairly, and transparently safeguarding their financial soundness and sustainability.

AB Bank Rwanda endorses the SMART Campaign fostering its seven key principles for responsible lending and customer protection:

Appropriate product design and delivery channels which are tailored to the specific needs of the bank’s target clientele – micro entrepreneurs in the informal sector


Prevention of over-indebtedness by ensuring the credit process determines client’s repayment capacity without becoming over-indebted

Transparency in pricing and product terms and conditions

Responsible pricing which is affordable to clients and allowing for the institution’s sustainability

Fair and respectful treatment of clients safeguarding against discrimination, corruption and any kind of aggressive or abusive treatment by its staff and agents

Mechanisms for complaint resolution
