This joint IMF-World Bank workshop gives an in-depth introduction to the current debt sustainability framework for low-income countries DSF LIC which was implemented in July 2018. The framework helps guide countries and donors in mobilizing the financing of LICs development needs while reducing the chances of an excessive buildup of debt in the future. Sessions combine lectures on key features with demonstrations of the modules of the excel-based DS LIC framework covering linkages between the macroeconomic framework and debt dynamics, realism tools, stress tests, debt carrying capacity thresholds, the role of judgment, and the determination of final ratings.
