This paper reviews the existing literature on microcredit with a focus on the formalization of commercial banks and an involvement of commercial banks in microcredit operations. It does so primarily through the analysis of microcredit financial methodologies and practices as well as of the specific institutional needs for microcredit operations. The paper contributes to the on-going discussion on the role of microcredit in development, particularly on its role in promoting and extending financial services to the poor and low-income people, especially to those starting-up new businesses.
