The CGAP Working Group on Microinsurance and USAID commissioned Banyan Global to develop a Note consolidating lessons and recommendations for donors supporting microinsurance. Banyan Global interviewed stakeholders working in this sector, presented findings at the Microinsurance Working Group meeting in 2007 and disseminated the report for review by industry experts. The Note provides an overview of current donor approaches for supporting microinsurance, synthesizes key lessons, and offers guidance for donors when channeling their assistance to the sector.
