Summary of the IMF and World Bank Review of Low-Income Country Debt Sustainability Framework and Implications of the MDRI

I. Introduction

This document reviews the implementation experience of the joint IMF-World Bank Debt Sustainability Framework (DSF) for low-income countries (LICs), focusing on the collaboration between the two institutions and the implications of the Multilateral Debt Relief Initiative (MDRI). The DSF was endorsed in April 2005 and aims to ensure that external financing for LICs does not lead to unsustainable debt burdens. It also examines how the MDRI, which provides debt relief to Heavily Indebted Poor Countries (HIPC), affects the sustainability of future borrowing.

II. Review of Low-Income Country Debt Sustainability Framework

A. Experience with the New Joint DSA Framework

• Implementation: As of the time of the report, 23 joint DSAs had been prepared for low-income countries, with most conducted within the context of IMF arrangements (16 out of 23) and two within staff-monitored programs (SMPs).
• Collaboration: The Bank and Fund staffs generally collaborated informally, even on Fund-only DSAs.
• Risk Classification: The DSF includes a four-tier classification system for debt distress risk:
  • Low risk: Debt indicators well below thresholds.
  • Moderate risk: Stress tests show significant increases in debt-service ratios.
  • High risk: Baseline scenarios indicate breach of debt thresholds.
  • In debt distress: Current debt and debt-service ratios are in significant or sustained breach of thresholds.
• CPIA Integration: The DSF uses the World Bank's CPIA index to classify countries into policy performance categories (strong, medium, poor), and sets three indicative thresholds for each debt indicator, with the highest thresholds for strong performers.
• Debt Relief Impact: Countries with low CPIA ratings or not yet eligible for MDRI relief were found to have higher risks of debt distress. Only two of the 23 DSAs were classified as high risk before MDRI relief, indicating the positive impact of the initiative.

B. Application of the DSF

• Usefulness: Country teams found the DSF templates and guidelines relatively easy to use, though preparation required substantial resources (on average, three staff weeks).
• Analysis Depth: The depth of analysis improved over time, with most DSAs including baseline and stress test scenarios, and some providing additional context on debt developments.
• Good Practices: Several best practices were identified:
  • Plan Bank-Fund collaboration in advance.
  • Discuss assumptions, findings, and policy implications with the authorities.
  • Integrate external and fiscal aspects of the DSA, especially in countries with weak tax systems.
  • Use alternative scenarios and stress tests to reflect country-specific features.
  • Present DSAs as self-contained documents with clear assumptions and conclusions.
  • Include detailed analysis of debt stock composition and evolution.
  • Explain the rationale behind risk assessments, especially in gray areas.
• Macroeconomic Projections: Projections were generally linked to past performance, with trend analyses and sectoral decomposition used to incorporate economic knowledge. However, behavioral relationships within the framework were often loosely defined.
• Baseline Projections: Baseline scenarios were more favorable than historical averages, leading to lower debt-burden indicators. In some cases, substituting the historical scenario with the baseline led to an adverse change in the debt distress rating due to temporary commodity price declines.

C. Usefulness to Other Donors and Creditors

• The DSF has been useful for other donors and creditors in understanding the debt sustainability of LICs.
• The framework provides a consistent and objective basis for assessing debt risks, which is essential for coordinating concessional financing.

D. Bank-Fund Collaboration

• The DSF has strengthened the IMF's surveillance and program design.
• It has fundamentally changed the World Bank's IDA grant allocation criteria, which now focus exclusively on debt distress risk.
• The collaboration between the Bank and Fund staffs has generally been effective, with minimal additional resource implications.

III. The Debt Sustainability Framework in Light of MDRI

A. Indicative Debt Thresholds

• The DSF uses indicative thresholds for debt burden indicators based on policy performance.
• These thresholds help determine the level of new borrowing a country can undertake.

B. Debt Accumulation Below the Thresholds

• The paper considers two approaches to managing debt accumulation in countries below the DSF thresholds:
  • Simple across-the-board rules, such as restrictions on changes in the net present value (NPV) of debt.
  • A case-by-case examination of each country's unique situation and needs.
• A case-by-case approach is generally preferred, as it allows for more tailored and context-specific assessments.

C. The DSF and the "Free Rider" Problem

• The "free rider" problem refers to the risk that nonconcessional debt could undermine the effectiveness of the DSF by allowing countries to borrow without sufficient oversight.
• The paper suggests that countries facing debt distress should avoid nonconcessional borrowing, while others may benefit from financing high-return projects on nonconcessional terms.
• A coordinated approach to concessionality by all creditors is ideal but challenging to implement.

IV. Conclusions and Issues for Discussion

A. Refinements to the DSF

• The DSF should be refined to better capture the complexity of debt assessments, particularly by incorporating a more integrated approach to domestic and external debt.
• A more finely calibrated set of ratings would allow for better tailoring of grant eligibility and responses to borderline cases.

B. Implications of MDRI

• The MDRI provides significant debt relief to HIPCs, improving their financial position and supporting efforts to achieve the Millennium Development Goals (MDGs).
• However, there is a risk of overindebtedness, and the paper raises three key questions:
  • Should the DSF debt thresholds be lowered?
  • How should debt accumulation be managed in countries well below the thresholds?
  • How can the "free rider" problem be addressed in the DSF?

Appendix: Post-MDRI Debt Scenarios

• The document includes post-MDRI debt scenarios, which show the potential impact of the initiative on future debt sustainability.
• These scenarios are used to evaluate the effectiveness of the DSF in the context of MDRI relief.

Key Takeaways

• The DSF has improved the assessment of debt sustainability for LICs and has strengthened the coordination between the IMF and World Bank.
• The framework has been instrumental in shaping IDA's grant allocation criteria, which now rely solely on debt distress risk.
• While the DSF has generally been effective, challenges remain, particularly in integrating domestic debt and addressing the "free rider" problem.
• The MDRI provides significant relief but must be accompanied by careful management of future borrowing to avoid renewed debt distress.
