Debt Sustainability Analysis (DSA) conducted by the multilateral organisations like the World Bank and IMF falls under the domain of Judgmental Projection reflecting their views or judgment about the economy.  The study incorporates time series forecast using ARIMA method to analyse debt sustainability in practice in Bangladesh. More specifically, macro, fiscal, current account and debt variables have been forecasted according to the requirement of debt sustainability framework (DSF) for use in a standard DSA template. Using the time series forecast based inputs, the study concludes that debt is sustainable for Bangladesh for the period 2013-2033 based on the standard country specific debt burden threshold. The study notes that the results produced by different methodologies broadly follow similar path. However, time series forecasts imply a better economic situation in terms of improved repayment capacity compared with judgmental projection.
