Kinshasa, the capital of the Democratic Republic of the Congo (DRC), is a case in point. The social and economic effects of the Covid’19 crisis have been devastating in this megacity of 15 million people, two-thirds of whom were poor pre-pandemic. Job losses, price increases, and a drop in remittances quickly increased the financial vulnerability of most households. The situation called for a large-scale emergency cash transfer program, even if none of the prerequisites were in place: no program administration to build on, no social registry or fiscal records to target beneficiaries, and a weak financial ecosystem to make payments. In short, the program had to be built from scratch, remotely, and fast. This case study reviews the challenge that the DRC Social Fund took up with the Solidarité par Transferts Economiques contre la Pauvreté à Kinshasa (STEP-KIN) program to boost digital cash transfers.
