The dynamics of overlapping borrowing in the microcredit sector of Bangladesh

Overlapping borrowing – i.e., the practice of taking new loans before old loans have been fully repaid – has become an important phenomenon in the microcredit sector in many developing countries, including Bangladesh. This paper examines the rationale for overlapping and investigates its short-term and long-term consequences by using a panel data set that is representative of Bangladesh as a whole. The study finds that it is useful to distinguish between two broad groups of overlapping borrowers who differ in terms of both the rationale of overlapping and its consequences. The first group – consisting of more than half of all overlapping borrowers – uses it as a promotional strategy, to improve their economic conditions without incurring a sharp discrete jump in debt burden. The other group uses it as a coping strategy, to deal with contingencies that compel them to take loans of a non-productive nature, again by avoiding a sharp discrete jump in the debt burden. Econometric analysis, allowing for the possibility of endogeneity bias, shows that the first group is able to achieve stronger financial viability in the long run in comparison with non-overlapping microcredit borrowers. The second group, in contrast, does not enjoy any significant improvement in their living conditions, but they are able to stave off any decline that otherwise might have befallen them in the face of shocks. Thus, both groups succeed in their respective goals, which are promotion for the first group and protection for the second. Microcredit has always had this duality of promotion and protection; overlapping borrowing serves to strengthen these functions of microcredit.
