Abstract: Micro insurance is a subset of insurance that acts as social security and social safety net to the poor. Its clients and operational methodology are different from formal insurance companies.Non Government Organizations(NGOs)/Microfinance Institutions(MFIs) are developing new financial products and services to meet increasing client demand and micro insurance is one of the products that are gaining wide concentration in the world of micro finance. The micro insurance concept in Bangladesh has been originated from the practice of microcredit programs of Grameen Bank and other NGOs/MFIs. In this paper we tried to see either micro-insurance services helpful or not. We found that micro0insurance is beneficial for its clients. Microinsurance is designed generally to address economic exclusion from resources, services, and/or social protection in the cases of death, ill-health, accident, and loss of property or other adversities of life. In fact, it is a kind of institutional risk mitigation service.
