The Low-Income Country Debt Sustainability Framework (LIC-DSF) is the joint analytical tool used by the IMF and World Bank to assess the risk that a low-income country will be unable to service its external and total public debt. First introduced in 2005 and substantively revised in 2017 (with the revised framework taking effect in July 2018), it underpins lending decisions, concessionality requirements, and grant allocations under the World Bank's International Development Association (IDA).
A Debt Sustainability Analysis (DSA) under the LIC-DSF projects debt and debt-service indicators over a 10- to 20-year horizon and compares them against indicative thresholds. Four key external debt burden indicators are tracked: the present value (PV) of external debt-to-GDP, PV of external debt-to-exports, external debt service-to-exports, and external debt service-to-revenue. A separate benchmark applies to the PV of total public debt-to-GDP.
Thresholds vary with a country's debt-carrying capacity, which the 2018 revision classifies as weak, medium, or strong based on a Composite Indicator (CI) combining the World Bank's Country Policy and Institutional Assessment (CPIA) score, real GDP growth, remittances, international reserves, and world growth. Stress tests (including a tailored natural-disaster, commodity-price, and market-financing module) are then applied.
Each DSA assigns one of four ratings of external debt distress risk: low, moderate, high, or in debt distress. Countries rated moderate are further assessed for the amount of "space" remaining under thresholds. These ratings directly shape IDA's grant-versus-credit mix under its grant allocation framework and inform IMF program design, including concessionality limits on new borrowing.
The LIC-DSF is distinct from the Sovereign Risk and Debt Sustainability Framework (SRDSF) used for market-access countries, which the IMF rolled out in 2022. Critics, including UNCTAD and several CSOs, argue the LIC-DSF underweights climate vulnerability and contingent liabilities, and that CPIA-based capacity measures embed governance biases.
Example
In its 2023 Article IV consultation with Ethiopia, the IMF used the LIC-DSF to classify the country as "in debt distress," informing its G20 Common Framework restructuring negotiations.
Frequently asked questions
The LIC-DSF applies to low-income countries that rely on concessional financing, while the Sovereign Risk and Debt Sustainability Framework (SRDSF), launched by the IMF in 2022, applies to market-access countries and emphasizes near-term rollover and market-pressure risks.
