Since 2013, IFC has supported the creation and growth of AB Bank Rwanda Limited through an equity investment and a local currency loan. The bank was established by IFC, AccessHolding, Kreditanstalt für Wiederaufbau (KfW), and the Dutch Entrepreneurial Development Bank (FMO). Sponsored by AccessHolding, an IFC partner in microfinance, AB Bank Rwanda is a regulated microfinance bank focused on expanding access to finance for micro, small, and medium enterprises (MSMEs) and low-income individuals. The bank began operations in 2014 and provides a range of financial services, including credit, savings, and remittances, primarily to urban and semi-urban entrepreneurs in Rwanda.

In September 2025, CAO received a complaint from an individual who is a client of AB Bank Rwanda. The complaint raised concerns related to predatory and harmful loan structure, unclear fees, intimidation and harassment by bank staff.

In December 2025, CAO found the complaint eligible and began its assessment.
