Evolution Of Debt Sustainability Analysis In Low Income Countries

The Debt Sustainability Analysis (DSA) for low-income countries (LICs) is a standardized analytical tool to monitor debt sustainability. This paper uses DSAs from three periods around the time of the global economic crisis to analyze the projected trajectories of debt ratios for a sample of LICs. The aggregate data suggest that LIC vulnerabilities improved on the whole during the period prior to the crisis, and that the crisis had a strong short-run impact on key ratios of debt (debt-to-GDP, -exports, and -fiscal revenues) and debt service (debt service-to-exports, and -revenues). Although projected debt burdens increased following the crisis, debt indicators tend to return to their pre-crisis levels over the projection horizon. This may reflect a strong and durable policy response by LICs towards the crisis, or also reflect specific assumptions on the long-run growth dividends of public external debt.

Low-income countries (LICs) face significant challenges in meeting their Sustainable Development Goals (SDGs) while at the same time ensuring that their external debt remains sustainable. In April 2005, the Executive Boards of the International Monetary Fund (IMF) and the International Development Association (IDA) approved the introduction of the Debt Sustainability Framework (DSF), a tool developed jointly by IMF and World Bank staff to conduct public and external debt sustainability analysis in low-income countries. The DSF has since been serving to help guide the borrowing decisions of LICs, provide guidance for creditors’ lending and grant allocation decisions, and improve World Bank and IMF assessments and policy advice. The latest review of the framework was approved by the Executive Boards in September 2017. This introduced reforms to ensure that the DSF remains appropriate for the rapidly changing financing landscape facing LICs and to further improve insights into debt vulnerabilities. This note provides operational and technical guidance on the implementation of the reformed framework.

This paper develops new error assessment methods to evaluate the performance of debt sustainability analyses (DSAs) for low-income countries (LICs) from 2005-2015. We find some evidence of a bias towards optimism for public and external debt projections, which was most appreciable for LICs with the highest incomes, prospects for market access, and at ‘moderate’ risk of debt distress. This was often driven by overly-ambitious fiscal and/or growth forecasts, and projected ‘residuals’. When we control for unanticipated shocks, we find that biases remain evident, driven in part by optimism regarding government fiscal reaction functions and expected growth dividends from investment.

The Debt Sustainability Framework for Low-income Countries (LIC DSF) has been the cornerstone of assessments of risks to debt sustainability in LICs. The framework classifies countries based on their assessed debt-carrying capacity, estimates threshold levels for selected debt burden indicators, evaluates baseline projections and stress test scenarios relative to these thresholds, and then combines indicative rules and staff judgment to assign risk ratings of external debt distress. The framework has demonstrated its operational value since the last review was conducted in 2012, but there are areas where new features can be introduced to enhance its performance in assessing risks. Against the backdrop of the evolving nature of risks facing LICs, both staff analysis and stakeholder feedback suggest gaps in the framework to be addressed. Complexity and lack of transparency have also been highlighted as causes for concern. This paper proposes a set of reforms to enhance the value of the LIC DSF for all users. In developing these reforms, staff has been guided by two over-arching principles: a) the core architecture of the DSF—model-based results complemented by judgment—remains appropriate; and b) reforms should ensure that the DSF maintains an appropriate balance by providing countries with early warnings of potential debt distress without unnecessarily constraining their borrowing for development.

Low-income countries (LICs) face significant challenges in meeting their development objectives while at the same time ensuring that their external debt remains sustainable. In April 2005, the Executive Boards of the International Monetary Fund (IMF) and the International Development Association (IDA) endorsed the Debt Sustainability Framework (DSF), a tool developed jointly by IMF and World Bank staff to conduct public and external debt sustainability analysis in low-income countries. The DSF aims to help guide the borrowing decisions of LICs, provide guidance for creditors’ lending and grant allocation decisions, and improve World Bank and IMF assessments and policy advice.

Introduced in 2005, the joint IMF-World Bank Debt Sustainability Framework (DSF) is a standardized framework for conducting public and external debt sustainability analysis (DSA) in low-income countries (LICs). It aims to help guide the borrowing decisions of LICs, provide guidance for creditors‘ lending and grant allocation decisions, and improve World Bank and IMF assessments and policy advice. The framework was previously reviewed in 2006 and 2009. This paper provides a comprehensive review of the framework to assess whether it remains adequate in light of changing circumstances in LICs. It reviews the DSF‘s performance to date, presents the results of recent analytical work by IMF and World Banks staffs, and discusses a number of areas in which the framework could be improved.
