In the face of multiplying humanitarian crises, cash transfers now account for nearly 20% of global aid, compared to just 6% a decade ago. This "cash revolution" has profoundly transformed the way aid is delivered, restoring choice and dignity to beneficiaries. However, a crucial question remains: do these transfers truly pave the way for more sustainable financial inclusion? This report produced in collaboration with PROPARCO and the ICRC, explores how humanitarian cash transfers—now a major form of aid—can serve as a gateway to financial inclusion for displaced and vulnerable populations. It examines the limitations of current practices, the role of financial service providers, and the conditions needed for sustainable access to financial services. Featuring insights from global experts and case studies, the report offers practical recommendations for linking aid to long-term economic empowerment.
