This note provides general guidance on Resilience and Sustainability Facility (RSF) operations, including for arrangement requests and reviews. The RSF provides longer-term, affordable financing to members to help them address risks to prospective BOP stability stemming from longer-term macro critical structural challenges from climate change and pandemic preparedness. The note has benefited from early experience gained during the operationalization of the RSF; the outcome of the May 2024 RST Interim Review; the launch of the Enhanced Cooperation Framework for Scaled Up Climate Action with the World Bank; and the approval of Broad Cooperation Principles on Pandemic Preparedness in RSF operations with the World Bank and the World Health Organization.
