The Bank of Tanzania's Monthly Economic Review for August 2025 highlights a stable national debt profile, with the total debt stock at USD 46,586.6 million as of the end of June 2025, marking a modest 1% increase from the previous month. This stability is evidenced by minimal fluctuations in both external and domestic components: external debt rose by just 0.1% to USD 32,955.5 million (70.7% of total debt), while domestic debt decreased by 0.4% to TZS 35,351.4 billion as of July 2025. The review attributes this equilibrium to prudent fiscal management, balanced debt inflows and outflows, and a focus on long-term instruments, which mitigate volatility. Supplementing this, external analyses from sources like the IMF and World Bank emphasize broader factors such as fiscal discipline and economic diversification, projecting a downward trend in public debt over the medium term.
Key Factors Contributing to Debt Stability
Several interconnected factors contribute to the stability of Tanzania's national debt, as outlined in the review and corroborated by recent economic assessments. These include controlled debt accumulation, effective revenue and expenditure management, and a strategic shift toward domestic financing, which reduces exposure to external risks like currency fluctuations.
1. Balanced Debt Inflows and Outflows
External debt disbursements significantly outpaced service payments, supporting liquidity without excessive accumulation. In June 2025, disbursements totaled USD 868.4 million, compared to debt service payments of USD 234.4 million (including USD 173.6 million in principal repayments). This net positive inflow (USD 634.0 million in net transfers) helped maintain stability while funding development needs.
The composition of external debt remained largely unchanged, with multilateral institutions holding 58.7% (USD 19,328.5 million), providing concessional terms that lower servicing costs and enhance sustainability.
Domestic borrowing was managed conservatively: The government raised TZS 514.4 billion (TZS 356.8 billion via Treasury bonds and TZS 157.6 billion via bills) but serviced TZS 670.8 billion, resulting in a net reduction. This reflects a deliberate strategy to align borrowing with repayment capacity.
2. Strong Fiscal Performance and Revenue Mobilization
Government revenue in June 2025 exceeded targets by 5.1%, reaching TZS 3,753.4 billion, driven by tax collections of TZS 3,108.7 billion (7.8% above target). This surplus enabled expenditures to stay within available resources at TZS 3,350.0 billion, reducing the need for additional borrowing.
Non-tax revenue, while below target at TZS 470.5 billion, was offset by robust tax administration improvements, contributing to fiscal space for debt management.
Broader fiscal discipline, including setting debt ceilings and coordinating monetary-fiscal policies, has been highlighted as a key stabilizer, preventing rapid debt growth amid spending pressures.
3. Shift Toward Domestic and Long-Term Financing
Domestic debt's slight decline (0.4%) was primarily due to reduced overdraft usage (from TZS 5,314.0 billion in June to TZS 4,990.5 billion in July), signaling improved liquidity management. Long-term instruments like Treasury bonds dominated at 79.7% (TZS 28,189.8 billion), offering predictable servicing and reducing rollover risks.
This domestic focus minimizes reliance on volatile external funds, as noted in analyses, where forex fluctuations (e.g., shilling depreciation) have historically driven debt increases. Commercial banks and pension funds held 28.8% and 26.4% of domestic debt, respectively, providing stable local creditor bases.
4. Economic Resilience and External Support
Stable inflation (3.3% in July 2025) and strong GDP growth projections (around 6% for 2025) underpin debt sustainability by boosting revenue and export performance. The current account deficit narrowed to USD 2,079.2 million in the year ending July 2025 (from USD 2,713.5 million), driven by export growth, reducing external borrowing needs.
Multilateral support and economic diversification (e.g., in mining and agriculture) further bolster stability, with Fitch affirming a 'B+' rating and stable outlook in June 2025, citing prudent policies despite wider deficits.
These figures demonstrate controlled growth and effective management, ensuring debt remains sustainable at around 60-65% of GDP based on recent estimates. However, risks like shilling depreciation and global uncertainties persist, underscoring the need for continued reforms.
