The World Bank and International Monetary Fund have reformed their Debt Sustainability Framework for Low-Income Countries, giving African governments including Tanzania a tool to manage debt while freeing resources for infrastructure, industrialisation and job creation. The World Bank approved the revised framework on September 15, 2026, following an IMF Executive Board review on September 9. The institutions announced the decision on September 21, with implementation expected in the second half of 2027. The framework's last major review was in 2017.
A key change is the introduction of a domestic debt module, recognising that borrowing in local currency carries risks. Heavy reliance on domestic banks, short-term securities requiring frequent refinancing and accumulated supplier arrears can expose governments to financial stress. Large holdings of government debt can also link banks' financial health closely to that of the state, and when confidence weakens, banks may become reluctant to lend to businesses, crowding out productive investment and employment creation.
The revised framework also seeks to account for long-term fiscal effects of infrastructure, human capital and climate investments. Productive projects including railways, ports, electricity networks and irrigation schemes can raise productivity, expand exports, create jobs and increase future tax revenue. However, cost overruns, weak demand, procurement failures, delays and expensive maintenance can undermine expected returns while debt repayments remain due. Independent project appraisals, realistic cost-benefit analysis and transparent estimates of fiscal and economic returns are therefore essential.
Other changes refine assessments of debt-carrying capacity and strengthen forecasting and stress tests, helping governments test how lower export prices, currency depreciation, higher interest rates and slower growth would affect their ability to service debt. The revised approach could also clarify the treatment of public liabilities and encourage better disclosure of risks associated with state-owned enterprises. The institutions' review found that the existing framework generally identified debt distress before it escalated into full-blown crises, although gaps remained in forecasting, debt coverage and the assessment of changing financing risks.
For Tanzania, the period before implementation begins in 2027 provides an opportunity to strengthen debt management and align borrowing with Dira 2050, the Fourth National Five-Year Development Plan and industrialisation priorities. The government should establish and regularly update an integrated fiscal-risk register covering central government debt, public corporations, guarantees, public-private partnerships, arrears and other contingent liabilities. Tanzania should also strengthen domestic revenue mobilisation through better tax administration, fewer unjustified exemptions and stronger compliance, providing more predictable resources for investment and debt servicing.
Success of the reforms will depend on responsible borrowing, credible data, realistic forecasts, stronger institutions and productive investment. For Tanzania and other African countries, debt reform will matter when better assessments lead to better decisions, creating jobs and growth without passing an unsustainable financial burden to future generations. However, challenges remain, including politically biased forecasts, limited technical capacity in some low-income countries and the risk that high-risk ratings could tighten lending conditions and discourage carefully assessed development projects.
