Tanzania’s debt development, as outlined in the April 2025 Monthly Economic Review and recent data, influences economic growth through fiscal constraints and resource allocation. Below, we analyze the debt structure, including domestic and external debt figures, percentage changes, and their implications for growth, using specific figures to illustrate impacts.

Debt Structure and Figures

Figures:

• Domestic Debt: TZS 34.26 trillion in March 2025, with 29% held by commercial banks and 26.5% by pension funds.
• External Debt: USD 34.1 billion (approximately TZS 91.29 trillion at TZS 2,677/USD, based on a 2.6% year-on-year exchange rate depreciation, Page 30), with 78.3% held by the central government and 67.7% denominated in US dollars.
• Total National Debt: TZS 91.7 trillion in 2024/25 budget context.
• Public Debt (Historical): 45.5% of GDP in 2022/23, up from 43.6% in 2021/22.
• Percentage Change: Exact year-on-year percentage changes for March 2025 debt are not provided in the document or search results. However, domestic debt uptake increased through treasury bills and bonds, and external debt grew to USD 34.1 billion (), suggesting continued borrowing. For context, public debt rose by 4.4% (45.5% - 43.6% of GDP) from 2021/22 to 2022/23.

Explanation:

• Domestic Debt: The TZS 34.26 trillion domestic debt finances fiscal deficits, with significant holdings by commercial banks (TZS 9.93 trillion, 29%) and pension funds (TZS 9.08 trillion, 26.5%). Increased borrowing indicates rising deficits, potentially driven by a 13.4% planned spending increase to TZS 57.04 trillion in FY 2025/26.
• External Debt: The USD 34.1 billion (TZS 91.29 trillion) external debt supports development projects, with 78.3% (USD 26.7 billion) held by the central government. The 67.7% USD denomination (USD 23.1 billion) exposes Tanzania to exchange rate risks, amplified by a 2.6%-shilling depreciation.
• Debt Sustainability: The IMF’s Debt Sustainability Analysis (DSA) indicates a moderate risk of external debt distress, with public debt at 35% of GDP in 2024, below the 55% benchmark (). Total debt service was 2.89% of GNI in 2023.

Impact on Economic Growth

Figures and Explanation:

• Fiscal Space Constraints: Limited fiscal space, noted globally, restricts Tanzania’s ability to fund growth. The FY 2024/25 budget of TZS 49.35 trillion includes TZS 29.41 trillion (59.6%) from tax revenue, leaving a deficit financed by domestic (TZS 34.26 trillion) and external (USD 34.1 billion) borrowing. A planned 13.4% spending increase to TZS 57.04 trillion in FY 2025/26 will further rely on debt, with TZS 16.07 trillion (28.2%) from borrowing.
• Debt Servicing Costs: Debt servicing absorbs significant resources. Historically, external debt servicing consumed 40% of government expenditures. In 2023, total debt service was 2.89% of GNI. For March 2025, servicing TZS 34.26 trillion domestic debt (at, e.g., 15.5% lending rates,) and USD 34.1 billion external debt (at concessional rates,) could cost TZS 5.31 trillion and USD 1-2 billion annually, diverting funds from investments. The 2.6%-shilling depreciation increases external debt costs by TZS 2.37 trillion.
• Crowding-Out Effect: Domestic borrowing of TZS 34.26 trillion (29% by banks) raises lending rates to 15.5%, crowding out private investment. Credit to the private sector weakened in Q4 2024, limiting business growth. The 6% Central Bank Rate mitigates this, but high government borrowing (TZS 4,362 billion average,) strains liquidity.
• Growth Projections: GDP growth is projected at 5.4% in 2024 and 6% in 2025, driven by agriculture (26.5% of GDP), construction (13.2%), and mining (9%). However, debt servicing and fiscal constraints could cap growth below the 6.4% potential by 2026.

Global and Domestic Economic Context

Figures and Explanation:

• Global Risks: The IMF’s global growth forecast of 2.8% for 2025 and rising interest rates increase external borrowing costs. Tanzania’s USD 34.1 billion external debt, with 67.7% in USD, faces higher servicing costs amid global tightening.
• Commodity Impacts: Declining coffee (-2%) and sugar (-1.5%) prices reduce export revenues, straining foreign exchange for debt repayment (Page 3). Gold prices at USD 2,983.25/ounce (+3%) and exports at USD 16.1 billion bolster reserves (USD 5.7 billion, 3.8 months of imports,), easing debt pressures.
• Inflation and Policy: Headline inflation at 3.3% and food inflation at 5.4% (Page 4) increase household costs, potentially slowing consumption. The 6% Central Bank Rate and 587,062-tonne food reserves (32,598 tonnes released) stabilize prices, supporting growth.

Opportunities and Mitigation

Figures and Explanation:

• Development Projects: External debt of USD 34.1 billion funds infrastructure (48% of World Bank’s USD 10 billion portfolio,), like the Standard Gauge Railway, boosting long-term growth. Projects worth TZS 14.81 trillion (30% of FY 2024/25 budget,) enhance connectivity and trade.
• Debt Management: The moderate debt distress risk and concessional financing keep debt sustainable. Revenue mobilization (TZS 2.47 trillion collected in March 2025,) and IMF’s USD 441 million ECF/RSF support () reduce reliance on costly borrowing.
• Fiscal Reforms: Plans to raise tax revenue to TZS 29.41 trillion (10% increase,) and reduce the fiscal deficit to 2.5% of GDP by 2024/25 () enhance fiscal space, freeing resources for growth.

Conclusion

Tanzania’s debt, at TZS 34.26 trillion domestic and USD 34.1 billion (TZS 91.29 trillion) external in March 2025, impacts growth by constraining fiscal space and diverting resources to servicing costs (e.g., TZS 5.31 trillion domestic, USD 1-2 billion external annually). A 2.6%-shilling depreciation and high lending rates (15.5%) exacerbate pressures, crowding out private investment. While debt fuels infrastructure (TZS 14.81 trillion in projects), declining exports (coffee -2%) and global risks (2.8% growth) challenge repayment. Prudent policy (6% CBR, USD 5.7 billion reserves) and revenue growth (TZS 29.41 trillion) mitigate risks, supporting 5.4%-6% GDP growth, but fiscal discipline is crucial.
