Yemen's economy has been transformed by eight years of violent conflict. War has shattered the country's already fragile economic equilibrium, touching upon virtually every aspect of life. The compounded shocks of the COVID-19 pandemic and rising global prices have only deepened the economic and humanitarian disaster precipitated by the war. Since the start of the conflict, economic analyses have tended to focus on the deterioration of macroeconomic indicators, the sharp rise in poverty and food insecurity, and the destruction of infrastructure and the capital stock, but relatively little attention has been paid to the current structure of the economy or what prospects can be envisaged for the country. Also, it is important to situate this analysis within the political economy dynamics of the country which majorly affect the economic development challenges of the country. Data constraints and the unique characteristics of Yemen's recent experience limit the effectiveness of traditional growth-analysis methodologies. This Country Economic Memorandum (CEM) uses novel data-collection methods and analytical techniques, triangulating its findings with traditional approaches and direct data collection to close the economic knowledge gap. Information sources include extensive key-informant interviews, household phone surveys, and remotely sensed geospatial data based on satellite imagery, including nighttime illumination data. This CEM also combines an in-depth political economy analysis with economic development investigation.
