When the world adopted the SDGs, policymakers knew that aid alone would never meet the financing needs. They embraced the “billions to trillions” vision, believing that an abundance of commercially viable SDG-related investments was ready and waiting for trillions in profitable private investment—if only development finance institutions (DFIs) and others could clear away the obstacles that stand between the investments and private investors. Reality looks different. To fill the gaps in the financial architecture, Nancy Lee and Dan Preston propose the Stretch Fund.
MDB private sector operations or windows (PSWs) are essential actors in mobilizing private finance for development, but their mobilization track record to date falls far short of a meaningful contribution to annual SDG financing gaps in the trillions
It is time to take a fresh look at the PSWs and to ask some basic questions about their role and instruments. The aim of this essay is to raise issues that need to be addressed as we think about how PSWs should evolve and adapt to meet the formidable challenges ahead. These questions and the answers gained through careful research can help chart the right course and set the right expectations for MDB PSWs, DFIs, and impact investors generally.
