This book examines partnerships between commercial banks and microfinance institutions (MFIs). It demonstrates that when set up properly, these partnerships have the potential to develop and enhance the financial inclusion agenda, and further support sustainable development. MFIs provide access to finance predominantly for those who are poor but economically active, and therefore their expansion is imperative for inclusive economic development. However, MFIs are faced with enormous challenges. The book discusses how partnering with a commercial bank can meet these challenges and the process of interaction contributing to the enhancement of institutional robustness of MFIs. Through two distinct case studies, in Cambodia and Australia, the book discusses the motivations, objectives, and operational dynamics of a partnership, as well as the challenges, success factors, and potential benefits, from the increase in outreach and sustainability, to the transference of knowledge and potential for capacity building. Similarly, the partnering banks benefit in line with the intended objectives – commercial or social besides help embedding social consciousness and improving staff engagement. Concluding with elucidating the characteristics of a partnership model that can succeed across different global contexts, the book will interest a range of researchers and students across development economics, banking, finance, and sustainable development.
