The Fourth International Conference on Financing for Development (FFD4) provides once-in-a-decade opportunity to address these impediments to the mobilization of private investment. As UN Member States are preparing for the negotiations of the FFD4 outcome document at the Second Preparatory Committee Session for FfD4, the Global Investors for Sustainable Development (GISD) Alliance will organize a side event to provide space for a discussion of ideas and recommendations to scale up blended finance, tackle local currency risk and for possible adjustments of regulatory frameworks that have the potential to unlock significant amounts of private capital for sustainable development. The side event will build on the relevant substantive workstreams conducted by the GISD Alliance, as well as inputs from members of the FFD4 Business Steering Committee.
