This document focuses on best practices and case studies of experiences of microfinance institutions serving the most vulnerable segments of the population in Latin American and the Caribbean. The report is based on the experiences of the Emergency Liquidity Facility (ELF), a contingency fund that provides short-term loans to support the liquidity of microfinance institutions that are affected by an exogenous phenomenon. The work draws on the experiences of the two facilities associated with ELF, the Technical Support Facility (TSF) and the Caribbean Technical Support Facility (CTSF), which together have provided training services preparedness and responsiveness to exogenous events to sixty-five microfinance institutions and other financial intermediaries in Latin America and the Caribbean.
