The ability to pay for a government-led investment strategy to achieve the millennium development goals (MDGs) is determined by the resources available to the government through economic growth, taxation, loans, and grants. Unsustainable public debts increase poverty directly through negative impacts on economic growth as well as indirectly through cuts in spending. Hence, the issue of fiscal debt sustainability is critical for achieving the MDGs. In this paper, we use the debt projection module of SimSIP Debt to project the evolution of Bangladesh's public debt over a 15-year horizon (from fiscal year 2006 to fiscal year 2021) under three different macroeconomic scenarios and two different financing scenarios of an ambitious government-led investment strategy.
