Research and citations

The primary sources the WSCC uses to size, monitor, and report on the global savings-club industry. Use this page as the citation backbone when writing about consórcios, Bausparkassen, stokvels, chit funds, chamas, tandas, susus, arisan, or the broader ROSCA universe.

How we measure the industry

The savings-club industry is the largest and least-measured non-bank financial system in the world. Most savings clubs operate informally, outside any registered structure, which means the formalized portion that is statistically tractable is dominated by a handful of regulated regimes: Brazil's consórcios, Germany's Bausparkassen, India's registered chit funds, and South Africa's formalized stokvels. Together these account for roughly USD 1.2 trillion in contracts and assets, and the WSCC estimates the broader global universe at USD 1.5 trillion in annual flows with 850 million participants across 190+ countries.

This page is the WSCC's working bibliography for the per-tradition reference pages and for our policy publications. Each entry is cited inline on the relevant tradition page.
