IMF, World Bank Approve Major Debt Sustainability Framework Reform for Low-Income Nations

Washington/Dhaka, September 22, 2026 — The International Monetary Fund and the World Bank have announced that their executive boards approved proposed reforms to the joint Debt Sustainability Framework (DSF) for low-income countries, marking the first comprehensive review of the framework since 2017. The revised rules are designed to better reflect a more complex and riskier global borrowing environment for developing economies, including Bangladesh.

🏛 The reforms were finalised following a joint review that began in 2024 and concluded in July 2026. The World Bank said the overhaul will improve analysis of risks to debt sustainability by refining how countries' debt-carrying capacity is measured and by introducing new tools to assess longer-term debt threats, including those arising from climate change.

📊 What the New Framework Changes

According to the World Bank statement, the reforms focus on five key areas:

• 📄 Better analysis of domestic debt — reflecting the shift in many low-income countries from concessional external borrowing to a more complex mix of domestic and external commercial borrowing.
• 🌡 Broader assessment of long-term development challenges, including climate change — a first for the DSF, which has historically focused on macroeconomic and external financing risks.
• 📈 Refined measurement of debt-carrying capacity — the methodology that classifies countries' capacity to take on debt and assigns them a debt-burden threshold.
• 🧮 Enhanced “realism tools” and stress tests — to ensure forecasts are consistent and accurate, addressing past criticism that DSF projections often over-optimistically assumed prolonged fiscal adjustment.
• 📋 Encouragement for countries to improve debt data transparency — a response to repeated episodes where hidden or under-reported debt obligations were discovered only after distress set in.

⏱ Implementation Timeline

📅 The revised framework is expected to become operational in the second half of 2027, the World Bank said. Until then, the existing 2017-era framework will continue to be applied to ongoing IMF programme reviews and World Bank lending operations.

A review completed in July 2026 confirmed that the existing DSF had worked well to identify debt distress episodes ahead of time and helped countries make informed borrowing and lending decisions. But it also identified several areas where the framework could be improved to account for new challenges at a time of elevated development needs and a sharp decline in official development assistance (ODA).

🌏 Why This Matters for Bangladesh

Bangladesh is currently one of the IMF's most-watched borrowers in South Asia, with a $4.0 billion IMF credit programme running through 2026 and a track record of borrowing from both multilateral and bilateral creditors — including Japan, China, the World Bank, ADB and the Islamic Development Bank. The country's external debt has grown notably in recent years to finance large infrastructure projects including the Padma Bridge, the Dhaka Metro Rail, the Rooppur Nuclear Power Plant, the Matarbari power hub and the Karnaphuli Underwater Expressway.

The revised DSF will be particularly relevant for Bangladesh in three ways:

• 💰 Domestic debt scrutiny — Bangladesh's domestic borrowing through National Savings Certificates (NSCs) and short-term treasury bills has been a long-standing concern, with NSC interest rates exceeding bank deposit rates and creating contingent liabilities for the government budget.
• 🌡 Climate change debt stress — Bangladesh is among the world's most climate-vulnerable countries; the new framework's climate lens will likely raise its debt-sustainability risk profile, given the cost of cyclone recovery, coastal embankment upgrades and adaptation infrastructure.
• 📈 Refined debt-carrying capacity — Bangladesh's export base is heavily concentrated in readymade garments, which carries concentrated revenue risk; the new methodology may produce a more cautious threshold for the country.

📜 Background: Why the 2017 Framework Was Showing Its Age

The previous DSF was finalised in 2017, before the COVID-19 pandemic, before the global monetary tightening cycle of 2022-2025, and before the recent wave of sovereign debt restructurings in Zambia, Sri Lanka, Ghana and Ethiopia. Many low-income countries saw rising debt levels and a shift in financing sources to include more domestic and external borrowing on commercial terms, including Eurobonds, syndicated bank loans, and bilateral arrangements with non-Paris Club creditors.

The IMF and World Bank use the DSF to assess a country's ability to take on new debt without jeopardising its ability to service existing loans. The framework feeds directly into IMF programme design, World Bank lending ceilings, and the debt restructuring decisions of the G20 Common Framework.

🧭 Realism Tools and Stress Tests

One of the more technical but consequential changes concerns the “realism tools” embedded in DSF analysis. These are the diagnostic tests that flag when a country's projected fiscal adjustment is significantly out of line with historical experience. Past IMF research showed that DSF projections frequently assumed fiscal consolidation paths that were far more ambitious than what countries had actually achieved in the preceding decade.

The revised framework strengthens these realism tools by:

• 📊 Comparing projected revenue mobilisation against the country's own ten-year track record.
• 📊 Stress-testing primary balance assumptions against documented outcomes in comparable peer countries.
• 📊 Cross-checking public investment projections against actual execution rates — a particularly relevant lens for Bangladesh, where ADP implementation has fallen to record lows in FY27.

📋 Declining ODA and the New Borrowing Mix

The World Bank's statement explicitly flagged a “sharp decline in official development assistance” as one of the drivers behind the framework update. For Bangladesh, this is a material shift. The country has historically benefited from significant concessional flows from the World Bank's IDA window and ADB's Asian Development Fund, both of which are now under pressure from competing global demands and donor budget cuts.

As concessional flows shrink, Bangladesh is increasingly turning to a mix of:

• 💵 IMF Extended Credit Facility / Extended Fund Facility tranches
• 💵 World Bank development policy lending
• 💵 Bilateral loans from Japan (JICA) and China
• 💵 Domestic bond markets and bank borrowing
• 💵 Planned sovereign dollar bond issuance targeted for December 2026

🏛 Strategic Implications

💼 For Bangladesh's Ministry of Finance and the Economic Relations Division (ERD), the revised DSF will be a key input into the FY28 budget framework. A more cautious debt-carrying capacity rating — particularly if the climate lens is applied — could constrain the volume of new borrowing the country can take on without triggering IMF concerns. That, in turn, could force a reprioritisation of the Annual Development Programme (ADP), which has already seen implementation rates fall to a record low of 1.85 per cent in the first two months of FY27.

The revised framework will also be a factor in Bangladesh's planned sovereign dollar bond later this year, since international investors will calibrate pricing partly based on how the IMF and World Bank assess the country's debt trajectory.

The World Bank said it would publish the full technical documentation for the revised framework in early 2027, ahead of operational rollout.
