Central Government Dominates 77.5%, Infrastructure Leads Fund Use (Sept 2025)

Tanzania’s external debt reached USD 35,438.2 million in September 2025, representing 69.8% of total national debt and marking a modest 1.2% month-on-month increase due to net disbursements. The debt is heavily concentrated in central government borrowing (77.5%), with private sector and government-guaranteed entities accounting for 15.1% and 7.4%, respectively. Sector-wise, infrastructure and transport dominate fund usage at 28%, followed by social welfare and education (20.4%), energy and minerals (14.3%), and agriculture and water (14%), reflecting a productive, growth-oriented allocation. Currency composition remains USD-heavy (66%), exposing Tanzania to exchange rate volatility, though partial diversification into EUR, CNY, and JPY provides some buffer. Overall, the external debt profile is concessional and long-term, supporting fiscal expansion, development projects, and macroeconomic stability, yet requires vigilant management of currency and concentration risks to safeguard debt sustainability and complement domestic financing for continued 6% GDP growth.

5. Summary Table — External Debt Indicators (September 2025)

Implications of Tanzania's External Debt Profile in September 2025

The external debt indicators for September 2025, as detailed in Section 2.7 (Debt Developments) of the Bank of Tanzania's (BOT) Monthly Economic Review (October 2025), portray a moderately expanding portfolio at USD 35,438.2 million (+1.2% MoM from disbursements exceeding amortizations by USD 443 million vs. USD 131 million), comprising 69.8% of total national debt (USD 50,772.4 million). Central government borrowing dominates (77.5%), with funds skewed toward productive uses like infrastructure (28%) and social sectors (20.4%), but heavy USD exposure (66%) amplifies currency risks amid shilling appreciation (+9.4% y/y). This structure—largely concessional (57% multilateral, average maturity 12.8 years)—supports fiscal expansion (TZS 618.5 billion deficit; Section 2.6) and 6.3% Q2 GDP growth, yet ties sustainability to export performance (service receipts +4.6% to USD 6,973.9 million; Section 2.8). Below, I break down implications by key dimensions, integrating broader context like low inflation (3.4%) and reserves (USD 6,657 million, 5.8 months import cover).

1. Borrower Composition: Public Sector Dominance Signals Fiscal Centralization

• Central Government (77.5%, USD 27,461.3M); Private (15.1%, USD 5,357M); Guaranteed (7.4%, USD 2,619.9M): Sovereign focus reflects reliance on multilateral/bilateral loans (e.g., IMF/World Bank for projects), with private share indicating emerging corporate access (e.g., mining firms). Guarantees cover state-owned enterprises (SOEs) in energy/infra.
• Broader Implications:
  • Positive: Concentrates risk management under fiscal policy, enabling concessional terms (low ~1.2% rates) to fund development (71.9% expenditure execution; Section 2.6). Private growth (15.1%) aligns with credit expansion (16.1% y/y), fostering diversification.
  • Risks: Limited private participation (15.1%) hampers market deepening, potentially crowding out FDI if guarantees strain budgets (e.g., SOE inefficiencies). High public share exposes to revenue volatility (87.2% collection).

2. User of Funds: Growth-Oriented Allocation with Multiplier Potential

• Transport/Infra (28%, USD 9,910.4M); Social/Education (20.4%, USD 7,238.1M); Energy/Minerals (14.3%, USD 5,058.7M); Agri/Water (14%, USD 4,964.3M): Over 76% targets high-impact sectors, with "others" (14%) including tourism/finance. This mirrors GDP drivers (construction 1.1%, mining 1.5%).
• Broader Implications:
  • Positive: Productive tilt boosts long-term returns (e.g., infra aiding exports USD 17,094.2 million; Section 2.8), supporting 6% full-year projection via reliable power and agri stocks (570,519 tonnes). Social focus enhances human capital, curbing unemployment risks.
  • Risks: Infra/energy concentration (42.3%) vulnerable to execution delays (national 71.9%; Section 2.6) or commodity shocks (oil down but metals volatile). Low finance/trade shares (9.3%) limit SME scaling.

3. Currency Composition: USD Heaviness Heightens Volatility Exposure

• USD (66%); EUR (17.7%); CNY (6.4%); JPY (5%); Others (4.9%): Dollar dominance ties to commercial/multilateral loans, with CNY/JPY linked to bilateral projects (e.g., Chinese infra, Japanese JICA).
• Broader Implications:
  • Positive: Shilling gains (+9.4%) reduce TZS servicing (~USD 1,215 million in 2025, 4.2% exports; Table 2.7.4), improving ratios (debt/GDP 40.1%, below EAC 50%). Diversification (EUR/CNY ~24%) buffers USD swings, aiding reserves.
  • Risks: 66% USD share amplifies costs if dollar strengthens (e.g., US policy; Section 1.0), potentially adding 10–15% to TZS burden. CNY exposure adds geopolitical ties, while global rates (commercial 35.6% debt) pressure amid inflation moderation (4.2% global).

4. Sustainability and Macroeconomic Linkages

• Overall Dynamics: +1.2% growth from net inflows sustains debt/GDP stability (external service 9.8% exports, down from 11.2% 2024), complementing domestic debt (29.4%, TZS 37,459.1 billion; prior analysis) and CA narrowing (deficit ~1.5% GDP). In Zanzibar, external surplus (USD 836.6M) offsets union risks.
• Broader Implications:
  • Positive: Concessional/long-term bias (57% multilateral) aligns with monetary easing (CBR 5.75%), preserving low inflation (3–5% target) and liquidity (IBCM 6.45%).
  • Risks: USD/commercial vulnerabilities (66%/35.6%) demand hedging/export diversification (tourism +15.8%; Section 2.8). Rising stock strains if revenues falter (mining taxes down).

5. Policy Context from the Review

• Synergies: Funds amplify output (agri/mining-led) and external strength (services surplus USD 3,884.4M). Projections: Debt/GDP <45% by 2026, with FX interventions (USD 11M sale) mitigating risks.
• Outlook: Prudent amid global uncertainties (trade index up); prioritize private borrowing and currency swaps.

In conclusion, September 2025's external debt profile implies a development-enabling yet risk-laden framework, with public/infra focus driving growth while USD concentration demands vigilant FX/debt management. This aligns with the Review's resilient outlook, but enhancing private/diversified borrowing is crucial for 2026 sustainability amid global pressures.

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.
