In recent years, cash transfer programming has emerged as one of the most significant innovations in humanitarian response. Major donors and agencies have made public commitments to increase its use, for instance through the Grand Bargain. Now, work is under way to build the sector-wide capacity to turn those commitments into action. The Global Cash Forum is a significant opportunity to address key collective action challenges to realise the potential of cash. The Global Cash Forum brings together some of the world’s leading stakeholders working on cash transfer programming in humanitarian response, including governments, the UN, NGOs and the private sector.
