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 guidance note was prepared by International Monetary Fund (IMF) and World Bank Group staff under a project undertaken with the support of grants from the Financial Sector Reform and Strengthening Initiative, (FIRST).The aim of the project was to deliver a report that provides emerging market and developing economies with guidance and a roadmap in developing their local currency bond markets (LCBMs). This note will also inform technical assistance missions in advising authorities on the formulation of policies to deepen LCBMs.

This Supplement provides additional guidance to IMF and World Bank staff on the implementation of the Bank-Fund Debt Sustainability Framework for Low Income Countries (LIC-DSF) approved in 2017 by the IMF and World Bank Boards. It complements the 2018 Bank-Fund Guidance Note on the LIC-DSF. Since the publication of the 2018 Guidance Note, several issues have increased in significance, requiring more tailored guidance on the implementation of the LIC-DSF to address these issues, including: • Greater prominence of risks from climate change. • Further increase in borrowing on commercial terms and in domestic markets. • Increased number and complexity of debt restructurings. This Supplement to the 2018 Guidance Note on the LIC-DSF provides further guidance on how to address these issues within the current framework. All aspects of the 2018 LIC-DSF Guidance Note remain in effect, except as modified in this Supplement.

A careful review has revealed significant scope to modernize and better align the MAC DSA with its objectives and the IMF’s lending framework. This note proposes replacing the current framework with a new methodology based on risk assessments at three different horizons. Extensive testing has shown that the proposed framework has much better predictive accuracy than the current one. In addition to predicting sovereign stress, the framework can be used to derive statements about debt stabilization under current policies and about debt sustainability.

The objective of the joint Bank-Fund debt sustainability framework for low-income countries is to support LICs in their efforts to achieve their development goals without creating future debt problems. Countries that have received debt relief under the Heavily Indebted Poor Countries (HIPC) Initiative and the Multilateral Debt Relief Initiative (MDRI) need to be kept on a sustainable track. Under the framework, country DSAs are prepared jointly by Bank and Fund staff, with close collaboration between the two staffs on the design of the macroeconomic baseline, alternative scenarios, the debt distress rating, and the drafting of the write-up
