In April 2025, Tanzania’s external debt reached USD 35.51 billion, with the central government holding 76.7% (USD 27.22 billion) and the private sector 23.3% (USD 8.28 billion), including significant interest arrears of USD 1.63 billion. Funds were primarily allocated to transport and telecommunications (21.5%), balance of payments and budget support (20.2%), and social welfare and education (19.9%), reflecting priorities in infrastructure and human capital. The debt, predominantly denominated in USD (67.4%), exposes Tanzania to exchange rate risks, mitigated by USD 5.3 billion in reserves. The following table summarizes these key figures.

1. External Debt Stock by Borrowers (April 2025)

The external debt stock represents the total outstanding debt owed to foreign creditors, categorized by borrower type, providing insight into the distribution of debt obligations.

Key Figures:

• Total External Debt Stock: USD 35,505.9 million
• Breakdown by Borrower:

Analysis:

• Central Government Dominance: The central government accounts for 76.7% of the external debt stock (USD 27,224.0 million), with nearly all being disbursed outstanding debt (DOD) at USD 27,146.1 million. The low interest arrears (USD 78.0 million, 0.2%) indicate effective debt servicing, consistent with the Monthey Economic Review’s note of fiscal discipline and a fiscal deficit target below 3% of GDP. TICGL confirm the central government as the largest borrower, holding 78% of external debt in December 2019, a trend that persists into 2025.
• Private Sector Debt: The private sector’s share of 23.3% (USD 8,278.1 million) is significant, with USD 6,641.1 million in DOD and USD 1,637.0 million in interest arrears (4.6% of total debt). The high arrears suggest repayment challenges, possibly due to foreign exchange shortages, as the Tanzanian Shilling (TZS) depreciated by 3.9% annually to TZS 2,684.41/USD in April 2025 (previous responses). TICGL note private sector credit growth of 13.2% in February 2025, indicating active borrowing but potential liquidity constraints.
• Public Corporations: The negligible share of public corporations (USD 3.8 million, 0.0%) reflects minimal external borrowing by state-owned enterprises, likely due to reliance on central government funding or domestic financing. This aligns with TICGL noting public corporations’ 0.4% share in 2019.
• Debt Sustainability: The IMF’s Debt Sustainability Analysis (DSA) indicates a moderate risk of external debt distress, with the public debt-to-GDP ratio at 35% in 2024, well below the 55% benchmark. The total external debt of USD 35.51 billion in April 2025, up from USD 32.09 billion in January 2025, suggests rising borrowing but within sustainable limits, supported by gross official reserves of USD 5.3 billion (4.3 months of import cover, previous responses).

Insights:

• The central government’s dominant share (76.7%) reflects its role in financing infrastructure and budget deficits, as seen in the Monthey Economic Review’s mention of Treasury bond auctions (TZS 519.6 billion successful bids, previous responses). Low arrears (0.2%) indicate proactive debt management.
• The private sector’s high interest arrears (USD 1,637.0 million) highlight vulnerabilities to currency depreciation and foreign exchange constraints, consistent with the Monthey Economic Review’s note of lower seasonal foreign exchange inflows (previous responses).
• The negligible public corporation debt suggests a centralized borrowing strategy, reducing fiscal risks from state-owned enterprises.

2. Disbursed Outstanding Debt by Use of Funds (April 2025)

This breakdown shows how external debt funds are allocated across economic sectors, reflecting government priorities and economic development goals.

Key Figures:

• Total Disbursed Outstanding Debt (DOD): Included in the total external debt of USD 35,505.9 million.
• Breakdown by Sector/Use:

Analysis:

• Transport & Telecommunication (21.5%): The largest share reflects significant investments in infrastructure, such as the Standard Gauge Railway (SGR) and telecommunications upgrades, aligning with the Monthey Economic Review’s focus on flagship projects. TICGL note transport and telecom as the top sector for external debt allocation since 2019 (27%), indicating sustained priority.
• BoP & Budget Support (20.2%): This substantial share supports fiscal and macroeconomic stability, addressing balance of payments (BoP) needs and budget deficits. The Monthey Economic Review reports a March 2025 deficit of TZS 284.3 billion (previous responses), likely financed partly through external loans, as confirmed by IMF disbursements (USD 440.8 million under the ECF).
• Social Welfare & Education (19.9%): The high allocation to social sectors underscores Tanzania’s focus on human capital, aligning with the World Bank’s Country Partnership Framework (2025–2029) emphasizing education and health. This supports the Third Five-Year Development Plan’s goals for inclusive growth.
• Energy & Mining (13.6%): Investments in energy (e.g., Julius Nyerere Hydropower Project) and mining (e.g., gold, contributing USD 3.66 billion in exports) reflect strategic priorities for energy security and resource development. TICGL confirm this sector’s importance, with 15% of debt allocated in 2019.
• Smaller Sectors: Agriculture (5.1%), real estate (4.7%), industries (3.9%), finance & insurance (3.9%), and tourism (1.6%) receive smaller shares, indicating diversified but less prioritized investments. The Monthey Economic Review notes agricultural export growth, suggesting some debt supports this sector’s productivity.

Insights:

• The focus on hard infrastructure (transport, telecom, energy) supports Tanzania’s Vision 2050 goals of structural transformation and 8% GDP growth by 2026, as infrastructure drives economic activity (5.6% GDP growth in 2024).
• The significant BoP and budget support (20.2%) reflects reliance on external financing for fiscal stability, consistent with the IMF’s ECF and RSF programs.
• The 19.9% allocation to social welfare and education aligns with efforts to close human capital gaps, as highlighted by the IMF’s call for increased social spending.

3. Disbursed Outstanding Debt by Currency Composition (April 2025)

The currency composition of external debt indicates exposure to exchange rate risks and borrowing TICGL.

Key Figures:

• Breakdown by Currency:

Analysis:

• US Dollar Dominance (67.4%): The USD’s dominant share exposes Tanzania to exchange rate risks, as the TZS depreciated by 3.9% annually to TZS 2,684.41/USD in April 2025 (previous responses). TICGL confirm USD dominance at 68.1% in January 2025, consistent with historical trends (68.9% in 2023). This reflects borrowing from multilateral institutions (e.g., IMF, World Bank) and commercial creditors, who account for 53.9% and 36.3% of external debt, respectively.
• Euro (16.8%): The significant Euro share indicates borrowing from European institutions or bilateral creditors (e.g., EU partners). The stable Euro share (16.1% in January 2025) suggests consistent European financing, likely for infrastructure and social projects.
• Chinese Yuan (6.3%): The Yuan’s share reflects China’s role as a key bilateral creditor, likely tied to infrastructure projects like the SGR. TICGL note China as a top FDI source, with Yuan-denominated loans growing in importance.
• Other Currencies (9.5%): This includes currencies like the Japanese Yen or multilateral basket currencies (e.g., IMF’s SDRs), reflecting diversified borrowing. The Monthey Economic Review’s mention of reserves (USD 5.3 billion, previous responses) supports Tanzania’s capacity to manage multi-currency debt obligations.

Insights:

• The USD’s 67.4% share heightens vulnerability to TZS depreciation, as seen in the 1.3% monthly depreciation from March to April 2025 (previous responses). The BoT’s intervention (USD 6.25 million sold in April 2025) mitigates this risk (previous responses).
• The Euro and Yuan shares indicate diversified creditor relationships, reducing reliance on a single currency but requiring careful debt management to avoid currency mismatches.
• The Monthey Economic Review’s stable reserves (4.3 months of import cover) and IMF support provide a buffer against currency-related risks.

Conclusion

Tanzania’s external debt in April 2025, totaling USD 35.51 billion, is predominantly held by the central government (76.7%, USD 27.22 billion), with the private sector contributing 23.3% (USD 8.28 billion), including significant interest arrears (USD 1.63 billion). Funds are primarily allocated to transport and telecommunications (21.5%), BoP and budget support (20.2%), and social welfare and education (19.9%), reflecting priorities in infrastructure and human capital. The debt’s currency composition, dominated by the USD (67.4%), followed by the Euro (16.8%) and Yuan (6.3%), exposes Tanzania to exchange rate risks, mitigated by reserves of USD 5.3 billion and BoT interventions. The debt profile supports growth (projected at 6% in 2025) and fiscal stability, with a moderate risk of distress per the IMF’s DSA.

The following table summarizes these key figures.

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.
