In June 2025, Tanzania’s national debt reached TZS 116.6 trillion (USD 45.4 billion), a 13.5% increase from TZS 102.8 trillion in June 2024, driven by external borrowing (70.7% of total, TZS 82.4 trillion) for infrastructure and fiscal deficits. The Tanzania Shilling (TZS) depreciated by 9.6% year-on-year against the USD (2,569.46 TZS/USD), raising external debt servicing costs (USD 1–2 billion annually), despite robust reserves of USD 5,307.7 million (4.3 months of import cover). Supported by tourism receipts (USD 7,104 million) and a moderate debt-to-GDP ratio (~44.3%), Tanzania’s debt and TZS remain sustainable in the short term, but import reliance and USD exposure (67.6% of external debt) pose long-term challenges.

Tanzania National Debt Overview (June 2025)

Tanzania’s national debt encompasses public debt (domestic and external) and private sector external debt, critical for assessing fiscal sustainability. The attached document and provided data offer insights into debt stock, composition, and servicing, which are analyzed below.

• Total National Debt:
  • Value: TZS 116.6 trillion (USD 45.4 billion at 2,569.46 TZS/USD).
  • Annual Increase: +13.5% from TZS 102.8 trillion (USD 43.8 billion at 2,345.38 TZS/USD) in June 2024.
  • Context: The document notes the national debt stock at USD 45,586.6 million (~TZS 117.1 trillion) in June 2025, aligning closely with the provided TZS 116.6 trillion. The 13.5% increase reflects increased borrowing for infrastructure (e.g., Standard Gauge Railway, Julius Nyerere Hydropower Plant) and fiscal deficits (2.5% of GDP in 2024/25). Earlier data shows USD 48,479.9 million in April 2025 and USD 48,217.0 million in February 2025, suggesting a slight decline by June due to repayments or exchange rate effects.
  • Debt-to-GDP Ratio: Estimated at ~44.3% based on a GDP of ~USD 102.6 billion (2022 GDP of USD 105.1 billion, adjusted for 5.6% growth in 2024 and 6% in 2025). The IMF’s 2024 Debt Sustainability Analysis (DSA) reports a public debt-to-GDP ratio of 35%, below the 55% benchmark for low-income countries, indicating moderate distress risk. However, World Economics estimates a higher GDP (~USD 155.5 billion), implying a lower ratio of ~29.2%, highlighting data variability.
  • Implications: The 13.5% debt increase supports growth-enhancing projects but raises servicing costs (~40% of government expenditures, per IMF). The moderate debt-to-GDP ratio suggests sustainability, but TZS depreciation (9.6% against USD) increases external debt burdens.
• Domestic Debt:
  • Stock: TZS 35.5 trillion (USD ~13.8 billion, 29.3% of total debt).
  • Annual Increase: +11.1% from TZS 32.0 trillion in June 2024.
  • Monthly Increase: +0.9% from May 2025 (~TZS 35.2 trillion, based on April 2025’s TZS 34,759.9 billion).
  • By Instrument:

By Creditor:

• Context: The document confirms TZS 85.9 billion raised via bonds in June 2025, with TZS 93.96 billion spent on debt service (TZS 60.13 billion principal, TZS 33.83 billion interest, correcting the document’s typo of TZS 276.8 billion). The 11.1% annual growth reflects financing of fiscal deficits (e.g., TZS 270.2 billion in May 2025 for Mainland Tanzania). Treasury bonds’ 83.2% share aligns with a shift to long-term instruments, reducing refinancing risks.
• Implications: The diversified creditor base (28.6% banks, 26.1% pension funds) and long-term bond dominance enhance stability, but high borrowing rates (15.5% lending rates) crowd out private sector credit, which weakened in Q4 2024. The document’s note on retail investor participation via TIPS (18.1% “Others”) supports financial inclusion.
• External Debt:
  • Stock: TZS 82.4 trillion (USD 33.0 billion, 70.7% of total debt).
  • Annual Increase: +14.8% from TZS 71.8 trillion (USD 30.6 billion) in June 2024.
  • By Borrower:

By Use of Funds:

By Currency:

• Context: The document’s tables (e.g., Table 2.2, 2.3, 2.4) confirm the external debt stock and composition, with USD 109.9 million disbursed in April 2025 for projects like SGR and TAZARA Railway (25.4% transport). The 14.8% increase reflects concessional loans (e.g., IMF’s USD 441 million ECF/RSF, World Bank’s USD 527 million) and non-concessional borrowing (34% of external debt). The 67.6% USD share amplifies risks from the 9.6% TZS depreciation.
• Implications: The central government’s 85.4% share aligns debt with development priorities (e.g., Vision 2050), but low industry (4%) and agriculture (6.5%) allocations limit structural transformation. High USD exposure increases servicing costs (USD 80.9 million in April 2025), with external debt service at ~2.89% of GNI in 2023.
• Debt Servicing:
  • Domestic: TZS 93.96 billion in June 2025 (TZS 60.13 billion principal, TZS 33.83 billion interest), per the document. Annual servicing was TZS 890.9 billion in February 2025 (TZS 609.9 billion principal, TZS 281 billion interest).
  • External: USD 80.9 million in April 2025, with annual estimates of USD 1–2 billion, driven by USD-denominated debt (67.6%) and TZS depreciation.
  • Context: Servicing absorbs ~40% of government expenditures, per IMF, straining fiscal space. Concessional loans (e.g., World Bank, 48% of external debt) mitigate costs, but non-concessional borrowing raises concerns.
  • Implications: High servicing costs limit development spending (33.7% of Zanzibar’s budget), necessitating revenue mobilization (TZS 2,689.2 billion in May 2025, 3.1% above target) and export growth.

Tanzania Shilling (TZS) Sustainability

The TZS’s sustainability is assessed through its exchange rate stability, depreciation trends, and impact on debt servicing, drawing from the provided data and document’s external sector insights (e.g., Charts 2.7.1–2.7.3, Table 2.7.1).

• Exchange Rate Performance:
  • USD/TZS (IFEM):
    • June 2024: 2,345.38
    • May 2025: 2,565.08
    • June 2025: 2,569.46
    • Annual Depreciation: -9.6%
    • Monthly Change: -0.2% (May to June 2025)
  • Bureau de Change:
    • Buying Rate: 2,574.33 TZS/USD
    • Selling Rate: 2,582.67 TZS/USD
  • Other Currencies:

• Context: The document notes improved IFEM liquidity in June 2025, driven by seasonal cash crop exports (e.g., cashew nuts, tobacco) and gold exports (USD 3,369.7 million annually). The 9.6% depreciation aligns with earlier trends (9% in 2024, 8% in 2023), but a slight 0.28% appreciation in October 2024 and 2.6% by January 2025 indicate periods of stability. The BoT’s USD 7 million intervention in January 2025 and reserves of USD 5,307.7 million (4.3 months of import cover) support orderly markets.
• Drivers:
  • Import Demand: Goods imports rose to USD 459.5 million in Zanzibar and USD 13,040.7 million for Tanzania (Table A7), driven by capital goods (e.g., SGR, hydropower).
  • Export Shortfalls: Zanzibar’s exports fell to USD 150.3 million (-11.9%), with cloves down 27.2%. Tanzania’s goods exports grew to USD 1,036 million (Table 2.7.1), led by gold and cereals (USD 501.3 million), but were insufficient to offset imports.
  • Global USD Strength: U.S. monetary tightening increased USD demand, impacting emerging market currencies like the TZS.
• Implications: The 9.6% depreciation raises import and debt servicing costs, contributing to inflation (3.4% in Zanzibar, 3.2% in Mainland). The narrow Bureau spread (0.3%) and low dollarization (3.2% of Mainland businesses use USD) indicate market confidence, but sustained depreciation pressures reserves.
• Forex Market Activity:
  • IFEM Volume: USD 65.4 million in June 2025, +12.6% from USD 58.1 million in May 2025 (document, Page 10). This reflects trade settlements and seasonal imports, compared to USD 95.7 million in December 2024.
  • Reserves: USD 5,307.7 million (Chart 2.7.1), covering 4.3 months of imports, down slightly from USD 5,323.6 million in January 2025 but sufficient per IMF’s 4-month threshold.
  • Implications: Increased IFEM activity signals robust demand, but reserves and BoT interventions (e.g., USD sales) ensure stability. Service receipts (USD 7,104 million, driven by tourism’s 10% arrival increase to 2,333,322) bolster forex inflows.
• TZS Sustainability:
  • Stability: The TZS’s “orderly and market-driven” performance (document, Page 10) and minimal monthly depreciation (-0.2%) indicate short-term stability, supported by reserves and interventions.
  • Risks: The 9.6% annual depreciation and high USD debt exposure (67.6%) increase servicing costs, with external debt service at USD 1–2 billion annually. Import reliance (USD 13,040.7 million) and export volatility (e.g., cloves) strain reserves.
  • Mitigating Factors: Tourism receipts (USD 7,104 million), FDI (USD 3.7 billion), and concessional financing (e.g., IMF’s USD 441 million) support forex inflows. The BoT’s 6% Central Bank Rate (Page 7) controls inflation (3%–5% target), stabilizing the TZS.
  • Implications: The TZS is sustainable in the short term, but long-term pressures from depreciation and import growth require export diversification (e.g., cereals, manufactured goods) and reserve accumulation.

Debt and TZS Sustainability Metrics

Key Insights and Policy Implications

1. Debt Sustainability:
   • Status: The TZS 116.6 trillion debt (44.3% of GDP) is sustainable per the IMF’s DSA (below 55% benchmark), with moderate distress risk. External debt’s 70.7% share and 14.8% growth support infrastructure (25.4% transport) but increase servicing costs (USD 1–2 billion annually).
   • Policy: Prioritize concessional financing (e.g., World Bank’s USD 527 million) and revenue mobilization (TZS 2,339.2 billion tax revenue in May 2025, 4.1% above target) to reduce non-concessional borrowing (34% of external debt).
2. TZS Sustainability:
   • Status: The 9.6% depreciation and stable monthly performance (-0.2%) indicate short-term TZS stability, supported by reserves (USD 5,307.7 million) and tourism receipts (USD 7,104 million). However, import reliance and USD debt exposure pose long-term risks.
   • Policy: Boost exports (e.g., cereals, USD 501.3 million; manufactured goods) via AfCFTA and diversify debt currencies to mitigate USD risks (67.6% share).
3. Debt-TZS Nexus:
   • Impact: TZS depreciation increases external debt servicing costs, with USD 22.3 billion (67.6%) in USD-denominated debt. This contributes to inflation (3.4% in Zanzibar) and fiscal pressure.
   • Policy: Strengthen reserves through FDI (USD 3.7 billion) and tourism (2.3 million arrivals) to stabilize the TZS and reduce servicing costs.
4. Economic Context:
   • Growth: 5.6% GDP growth in 2024 and 6% projected for 2025 support debt absorption, driven by tourism and infrastructure.
   • Risks: TZS depreciation, global USD strength, and export volatility (e.g., cloves -27.2%) threaten sustainability. Climate shocks and election uncertainties (October 2025) add risks.
   • Opportunities: Vision 2050, MKUMBI II reforms, and digital financial inclusion (TIPS, 453.7 million transactions) enhance fiscal and TZS resilience.

Critical Examination of the Establishment Narrative

• Debt Optimism: The BoT and IMF emphasize sustainability (35% debt-to-GDP), but the 13.5% debt increase and 9.6% TZS depreciation raise servicing concerns, especially with USD debt (67.6%). The IMF’s moderate risk rating may understate long-term vulnerabilities if exports (e.g., cloves) or tourism falter.
• TZS Stability: The BoT’s “orderly market” narrative (Page 10) is supported by reserves and interventions, but high import demand (USD 13,040.7 million) and global USD strength challenge long-term TZS sustainability. X posts on regional debt (e.g., Kenya’s unsustainable levels) suggest broader risks.
• Crowding Out: The narrative overlooks domestic borrowing’s crowding-out effect (15.5% lending rates), limiting private sector credit (12.8% growth in January 2025) and Vision 2050’s private sector-led goals.

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.

Tanzania's external debt reached USD 33.91 billion in January 2025, placing it among the top 10 most indebted African countries. This marks a significant rise from USD 2.47 billion in 2011, reflecting increased borrowing for infrastructure and economic development. The central government holds 77.4% of the debt, with USD 185.4 million paid for debt servicing in December 2024. Despite this, Tanzania’s debt-to-GDP ratio remains at 47.2%, below the IMF’s 55% risk threshold. However, careful debt management is crucial to ensure economic stability and sustainable growth.

​As of January 2025, Tanzania's external debt stood at approximately USD 33,905.10 million, a slight decrease from USD 34,075.50 million in December 2024. This positions Tanzania among the top ten African countries with substantial external debt.​

Historical Context: Over the years, Tanzania's external debt has exhibited significant growth:​

• December 2011: USD 2,469.70 million​
• December 2023: USD 29,541.7 million ​
• November 2024: USD 33,137.7 million ​
• December 2024: USD 34,075.50 million​
• January 2025: USD 33,905.10 million​

Composition of External Debt: The central government holds the majority of this debt, accounting for approximately 77.4% as of December 2024. The remaining portion is attributed to the private sector. ​

Debt Service and Disbursements: In December 2024, Tanzania received external loan disbursements totaling USD 376.8 million, primarily allocated to the central government. During the same period, the country serviced its external debt with payments amounting to USD 185.4 million, which included USD 111.2 million in principal repayments and USD 74.2 million in interest payments. ​

Public Debt Relative to GDP: As of November 2024, Tanzania's total public debt, encompassing both external and domestic obligations, was USD 38,243.5 million. This figure represents approximately 47.2% of the nation's Gross Domestic Product (GDP). ​

International Financial Support: In December 2024, the International Monetary Fund (IMF) completed a review under the Extended Credit Facility arrangement with Tanzania, resulting in an immediate disbursement of about USD 148.6 million. Additionally, the IMF approved a disbursement of approximately USD 55.9 million under the Resilience and Sustainability Facility, totaling USD 204.5 million in financial support. ​

These figures underscore Tanzania's significant external debt position within Africa, highlighting the importance of ongoing fiscal management and international financial collaborations.

Top ten African countries with high external debt based on 2025 data:

1. South Africa – USD 176,314 million (Sep 2024)
2. Egypt – USD 155,204 million (Sep 2024)
3. Tunisia – TND 128,856 million (Sep 2024)
4. Mauritius – MUR 96,713 million (Dec 2024)
5. Angola – USD 50,260 million (Dec 2023)
6. Nigeria – USD 42,900 million (Sep 2024)
7. Namibia – NAD 36,036 million (Jun 2024)
8. Tanzania – USD 33,905 million (Jan 2025)
9. Malawi – MWK 5,887,049 million (Dec 2023)
10. Burundi – BIF 1,873,263 million (Dec 2024)

Tanzania’s external debt and its position among African countries with significant debt levels:

1. Tanzania’s Debt Growth is Significant

• Tanzania's external debt has increased dramatically from USD 2.47 billion in 2011 to USD 33.91 billion in January 2025.
• This consistent rise reflects increased borrowing for infrastructure, public services, and economic projects but also raises concerns about debt sustainability.

2. Tanzania is Among Africa’s Top 10 Most Indebted Countries

• At USD 33.91 billion, Tanzania ranks 8th in Africa for external debt.
• While this debt level is high, it is still lower than economies like South Africa (USD 176.3B), Egypt (USD 155.2B), and Nigeria (USD 42.9B).

3. Most of Tanzania’s Debt is Public

• 77.4% of Tanzania’s external debt is held by the central government, meaning the government is the primary borrower.
• This suggests reliance on international loans for development, infrastructure, and fiscal needs.

4. Debt Servicing is a Major Challenge

• In December 2024, Tanzania borrowed USD 376.8M but also had to repay USD 185.4M (including interest payments).
• This means that a significant portion of revenues is spent on debt servicing, which could limit spending on public services.

5. IMF and International Financial Support Play a Key Role

• The IMF provided USD 204.5M in December 2024 to support Tanzania’s financial stability.
• This suggests Tanzania relies on international financial institutions to manage its debt obligations and sustain economic programs.

6. Tanzania’s Debt-to-GDP Ratio is Still Manageable

• Tanzania’s total public debt (domestic + external) was USD 38.24 billion, accounting for 47.2% of GDP in November 2024.
• While below the IMF’s 55% risk threshold, continued borrowing without sufficient economic growth could lead to debt distress.

7. Comparison with Other African Countries

• South Africa and Egypt have the highest external debts, but their economies are larger and more diversified.
• Nigeria has slightly higher debt than Tanzania, but its economy benefits from oil revenues.
• Tanzania’s debt is higher than Malawi, Burundi, and Namibia, suggesting it is borrowing at a faster rate.

Final Conclusion

Tanzania's rising external debt reflects ambitious economic growth plans but also poses risks of debt distress if borrowing continues at this rate without sufficient revenue growth. Proper debt management, economic diversification, and increased exports are crucial to ensuring sustainability.
