This thematic third volume of the Asia Small and Medium-Sized Enterprise Monitor 2021 focuses on the digitalization of microfinance in Bangladesh. The MSME sector provides much of the income in rural Bangladesh, but its growth is constrained by limited access to affordable finance. This volume reports on a 2021 baseline study carried out in Bangladesh to pilot a randomized controlled trial to determine whether a digitalized group-based credit scheme could be introduced at an affordable price. The findings provide justification for further study on the digitalization of microfinance.
