This paper presents Islamic Republic of Mauritania’s 2024 Article IV Consultation, Third Review under the Arrangement’s under the Extended Credit Facility and Extended Fund Facility, Request for Modification of Quantitative Performance Criteria, and Second Review under the Resilience and Sustainability Facility (RSF) Arrangement. The Mauritanian economy has remained resilient, with economic growth projected to slow to 4.6 percent in 2024. Growth is expected to remain favorable in the medium term. Enhancing revenue mobilization, strengthening banking supervision, and sustaining the implementation of the national governance action plan would support private sector-led inclusive growth. Program performance has been strong. Mauritania’s reform drive and sound macroeconomic management have helped strengthen debt sustainability and resilience to shocks, while creating policy space for pressing infrastructure and social spending. Continued implementation of the ambitious climate change adaptation and mitigation reform measures, supported by the RSF, will help address Mauritania’s medium- and long-term term challenges and catalyze additional financing.
