Chamas are informal cooperative societies used to pool and invest savings by people in East Africa, particularly Kenya.
In Kenya, there are estimated to be 300,000 chamas that control up to a total of KSH 300 billion (US$3.4 billion) in assets.
Chamas have become impressive tools of economic empowerment that follow the spirit of harambee, the Kiswahili word for 'all pull together'. They help alleviate poverty by providing a means to pay tuition for children, make small-scale investments in community development, buy household items, and more.
