Effectiveness of this new tool in alleviating poverty, sustainability of the beneficiaries cum borrowers, sustainability of the microfinance institutions in the absence of donor funds, transparency in their operations, and questions related to practice of good governance came to the forefront of discussion with the maturity of this sector. As a result, the issue of regulation and supervision of this sector had opened up a whole range of debates and further exploration around different modes of operations being practiced. The central banks of most developing countries prepared to deal with the issue of microfinance regulation as a new type of financial sector. With this backdrop, Bangladesh’s Microcredit Regulatory Authority (established under Microcredit Regulatory Authority Act, 2006) felt the necessity to examine various aspects of regulations and to share experiences with other countries. A three day international conference on Microfinance Regulations was organized from 15th March 2010. Eleven papers from eight countries from Asia, Africa and Latin America were presented at the conference. Later this were revised and prepared as original paper.
