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.

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
2. User of Funds: Growth-Oriented Allocation with Multiplier Potential
3. Currency Composition: USD Heaviness Heightens Volatility Exposure
4. Sustainability and Macroeconomic Linkages
5. Policy Context from the Review
| Category | Amount/Share (USD Million) | Key Implication |
| Total External Debt | 35,438.2 (69.8% national) | +1.2% MoM; concessional for growth, but FX-exposed. |
| By Borrower | Central Govt: 27,461.3 (77.5%) Private: 5,357 (15.1%) Guaranteed: 2,619.9 (7.4%) | Public focus aids control; boost private to diversify. |
| By User | Infra: 9,910.4 (28%) Social: 7,238.1 (20.4%) Energy: 5,058.7 (14.3%) Agri: 4,964.3 (14%) | Productive (76%+); multipliers for 6% GDP, but delay risks. |
| By Currency | USD: 66% EUR: 17.7% CNY: 6.4% JPY: 5% | Shilling buffers costs; hedge USD to curb volatility. |
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.
