Central Government Dominates Borrowing as USD Exposure Heightens Currency Risks

As of June 2025, Tanzania’s external debt stock stood at USD 32,955.5 million (approximately TZS 82.4 trillion, assuming an exchange rate of TZS 2,500/USD), reflecting a marginal increase of 0.1% from the previous month. This external debt comprises about 70.7% of the total national debt, highlighting the country's continued reliance on foreign financing. The central government remains the primary borrower, holding 85.4% of the external debt (USD 28.1 billion), followed by the private sector with 14.6% (USD 4.8 billion), while public corporations account for a negligible share. Most of the disbursed debt is allocated to priority sectors such as transport & telecommunications (25.4%), social welfare & education (21.3%), and energy & mining (16.4%). However, 67.6% of the debt is denominated in USD, exposing the country to significant exchange rate risks amid recent currency depreciation. Despite prudent debt servicing—interest arrears are relatively low—the narrow fiscal space underscores the need for careful management and stronger domestic revenue mobilization.

1. External Debt Stock by Borrower – June 2025

The external debt stock represents the total outstanding debt owed to foreign creditors, including principal and interest arrears. As of June 2025, Tanzania’s external debt stock stood at USD 32,955.5 million (approximately TZS 82.4 trillion, assuming an exchange rate of ~TZS 2,500/USD, consistent with recent BoT reports). This reflects a marginal monthly increase of 0.1% from May 2025 and accounts for approximately 70.7% of Tanzania’s total national debt (external and domestic combined).

Total External Debt

• Amount: USD 32,955.5 million
• Monthly Increase: +0.1% (approximately USD 32.9 million, assuming May 2025 debt was ~USD 32,922.6 million).
• Share of Total National Debt: ~70.7%, indicating a significant reliance on external financing compared to domestic debt (e.g., TZS 32,615.7 billion in September 2024, per TICGL).
• Context: The slight increase aligns with trends observed in earlier months, such as a 0.5% decline from December 2024 to January 2025 (USD 33,905.1 million to USD 33,137.7 million), followed by an increase to USD 35,039.8 million by February 2025, reflecting fluctuations due to new disbursements and debt servicing. The African Development Bank notes that Tanzania’s fiscal deficit, projected at 2.5% of GDP in FY 2024/25, is partly financed by external borrowing, supporting this trend.

Breakdown by Borrower

The following table summarizes the external debt stock by borrower category for June 2025:

• Central Government:
  • Amount: USD 28,133.7 million (85.4% of total external debt).
  • Disbursed Outstanding Debt (DOD): USD 28,055.0 million, indicating that nearly all central government debt is disbursed and actively financing projects.
  • Interest Arrears: USD 78.7 million, a minor portion (0.28% of central government debt), suggesting effective debt servicing for public debt.
  • Context: The central government’s dominance (85.4%) is consistent with historical trends, with shares of 76.8% in November 2024 and 78.1% in September 2024. This reflects the government’s role in funding major infrastructure projects (e.g., Standard Gauge Railway, Julius Nyerere Hydropower Project) and social services, as noted in the FY 2024/25 budget allocating TZS 14.08 trillion for development expenditure.
  • Implications: The high share underscores the public sector’s reliance on external financing for development goals, placing a significant repayment burden on public finances. The low interest arrears indicate prudent debt management, supported by multilateral concessional loans (54.5% of external debt in November 2024).
• Private Sector:
  • Amount: USD 4,820.6 million (14.6% of total external debt).
  • DOD: USD 4,630.7 million, with interest arrears of USD 189.9 million (3.9% of private sector debt).
  • Context: The private sector’s share has declined slightly from 23.6% in January 2025 (USD 8,004.7 million) and 21% in December 2019, reflecting reduced access to foreign credit, possibly due to tighter global lending conditions or currency risks. The World Bank notes that private sector borrowing constraints may hinder economic diversification.
  • Implications: The higher interest arrears (relative to the central government) suggest challenges in private sector debt servicing, potentially due to exchange rate fluctuations (67.6% USD-denominated debt) or weaker cash flows in sectors like agriculture and industry.
• Public Corporations:
  • Amount: USD 1.3 million (negligible share).
  • Context: Public corporations (e.g., TANESCO, Tanzania Ports Authority) have minimal external debt exposure, consistent with January 2025 (USD 3.8 million). This reduces government liability risks from state-owned enterprises.
  • Implications: The negligible share reflects a deliberate strategy to limit public corporation borrowing, aligning with fiscal reforms to improve state-owned enterprise performance, as evidenced by TZS 1.028 trillion in dividends collected in FY 2024/25.

Key Takeaway

• The central government’s 85.4% share of external debt highlights its role in driving debt-financed development, particularly in infrastructure and social services. The private sector’s reduced share and higher arrears indicate challenges in accessing and servicing foreign credit. The negligible debt of public corporations minimizes fiscal risks but limits their role in external financing.

2. Disbursed Outstanding Debt (DOD) by Use of Funds – % Share

The DOD represents the portion of external debt that has been disbursed and is actively funding projects or sectors. The allocation of DOD reflects Tanzania’s development priorities under Vision 2050 and the Third Five-Year Development Plan (FYDP III).

Breakdown by Use of Funds

The following table summarizes the percentage share of DOD by sector for June 2025:

• Transport & Telecommunication (25.4%):
  • Context: This sector receives the largest share, consistent with historical trends (21.4% in November 2024, 21.5% in September 2024). Key projects include the Standard Gauge Railway (SGR), port expansions, and ICT infrastructure, aligning with Tanzania’s goal to enhance connectivity and trade under FYDP III.
  • Implications: Investments in transport (e.g., SGR, Dar es Salaam port) and telecommunications (e.g., 5G networks) support economic growth by improving logistics and digital access. However, the high allocation may crowd out funding for other sectors like agriculture.
• Social Welfare & Education (21.3%):
  • Context: This sector’s significant share (20.4% in November 2024, 20.8% in September 2024) reflects investments in human capital, such as free education programs and healthcare infrastructure. The World Bank’s USD 227 million financing for climate and marine conservation in June 2025 also supports social welfare.
  • Implications: Funding education and social welfare enhances workforce development and poverty reduction, critical for long-term growth. However, recurrent costs (e.g., teacher salaries) may compete with capital investments.
• Energy & Mining (16.4%):
  • Context: Investments in energy (e.g., Julius Nyerere Hydropower Plant) and mining (e.g., gold, critical minerals) align with Tanzania’s energy access goals and export growth (gold exports up 24.5% in April 2025). The sector’s share is slightly higher than November 2024 (15%).
  • Implications: Energy investments address power shortages, supporting industrial growth, while mining boosts export revenues. However, environmental and governance risks in mining require careful management.
• Budget Support (15.2%):
  • Context: This share (19.9% in January 2025) reflects external loans used to finance recurrent expenditures, such as salaries and debt servicing. The African Development Bank notes that reliance on budget support poses fiscal risks if external financing decreases.
  • Implications: High budget support allocation indicates fiscal pressures, as seen in the TZS 270.2 billion deficit in May 2025. Reducing reliance on external budget support through domestic revenue mobilization (e.g., TZS 2,880.2 billion in May 2025) is critical.
• Agriculture (6.5%):
  • Context: The low share (5.1% in September 2024) is surprising given agriculture’s role in Tanzania’s economy (25% of GDP, 65% of employment). Investments support irrigation and agribusiness but are limited compared to infrastructure.
  • Implications: Underfunding agriculture may constrain rural development and food security, despite export growth in cashew nuts (141% in April 2025).
• Finance & Insurance (5.1%) and Industry (4.0%):
  • Context: These sectors receive minimal allocations (4.0% for industry in January 2025), reflecting limited focus on manufacturing and financial sector development. The World Bank highlights declining industrial productivity as a constraint on economic diversification.
  • Implications: Low funding may hinder Tanzania’s industrialization goals under Vision 2050, limiting job creation and export diversification.
• Others (6.1%):
  • Context: Includes water, balance of payments support, and miscellaneous projects. The World Bank’s USD 300 million financing for disaster preparedness in June 2025 may contribute to this category.
  • Implications: Diverse allocations support resilience but dilute focus on priority sectors.

Key Takeaway

• The focus on Transport & Telecommunication (25.4%) and Social Welfare & Education (21.3%) reflects Tanzania’s commitment to infrastructure-driven growth and human capital development. However, the low shares for agriculture (6.5%) and industry (4.0%) may limit inclusive growth, given their economic significance.

3. DOD by Currency Composition – % Share

The currency composition of DOD indicates the foreign currencies in which Tanzania’s external debt is denominated, exposing the country to exchange rate risks.

Breakdown by Currency

The following table summarizes the percentage share of DOD by currency for June 2025:

• US Dollar (USD) (67.6%):
  • Context: The USD’s dominance is consistent with historical trends (67.4% in September 2024, 68.1% in January 2025). This reflects borrowing from multilateral institutions (e.g., World Bank, IMF) and commercial creditors, often denominated in USD.
  • Implications: High USD exposure makes Tanzania vulnerable to exchange rate fluctuations. The Tanzanian Shilling depreciated by 8% in 2023, increasing debt servicing costs. A stronger USD in 2025 could further strain public finances, as noted by The Citizen.
• Euro (EUR) (17.2%):
  • Context: Euro-denominated debt (16.1% in January 2025) reflects loans from European institutions (e.g., European Investment Bank). The slight increase may indicate new Euro-based financing.
  • Implications: Diversification into Euros reduces USD reliance but exposes Tanzania to Eurozone economic conditions.
• Japanese Yen (JPY) (4.9%) and Chinese Yuan (CNY) (3.4%):
  • Context: JPY and CNY shares align with bilateral loans from Japan and China, supporting infrastructure projects like the SGR. The CNY share is lower than in January 2025 (6.3%), possibly due to reduced Chinese lending.
  • Implications: These currencies provide some diversification, but their small shares limit risk mitigation.
• Special Drawing Rights (SDR) (3.0%) and Others (3.9%):
  • Context: SDRs are used by multilateral institutions like the IMF, while “Others” include British Pound and minor currencies. The low SDR share reflects limited IMF financing in June 2025.
  • Implications: Diversified borrowing in SDRs and other currencies offers some stability but is insufficient to offset USD risks.

Key Takeaway

• The 67.6% USD share exposes Tanzania to significant exchange rate risks, particularly with Shilling depreciation. Diversification into Euros, JPY, and CNY helps but is limited by their smaller shares. Prudent debt management and revenue mobilization are critical to mitigate currency risks.

The following table consolidates the key figures for June 2025:

Policy Implications and Insights

1. Central Government Borrowing:
   • The central government’s 85.4% share of external debt aligns with its role in funding infrastructure and social services, as seen in the TZS 937.3 billion development expenditure in May 2025. However, this concentrates repayment risks on public finances, requiring robust revenue mobilization (e.g., TZS 2,880.2 billion in May 2025).
   • The low interest arrears (USD 78.7 million) indicate effective debt management, supported by concessional loans from multilateral creditors (54.5% of debt).
2. Private Sector Constraints:
   • The private sector’s 14.6% share and higher arrears (USD 189.9 million) suggest challenges in accessing and servicing foreign credit, potentially due to USD appreciation or global tightening. This aligns with TICGL’s observation of declining private sector borrowing slowing economic diversification.
3. Sectoral Allocation:
   • The focus on Transport & Telecommunication (25.4%) and Social Welfare & Education (21.3%) supports Tanzania’s Vision 2050 goals of connectivity and human capital development. However, the low shares for agriculture (6.5%) and industry (4.0%) may hinder inclusive growth, given agriculture’s role in employment and GDP.
4. Currency Risks:
   • The 67.6% USD share exposes Tanzania to exchange rate risks, as noted by The Citizen, with Shilling depreciation increasing debt servicing costs. The African Development Bank emphasizes the need for domestic revenue mobilization to mitigate these risks.
   • Diversification into Euros (17.2%) and other currencies is positive but insufficient to offset USD dominance.
5. Debt Sustainability:
   • The IMF’s 2024 Debt Sustainability Analysis (DSA) indicates a moderate risk of external debt distress, with public debt at 45.5% of GDP in 2022/23, well below the 55% benchmark. The slight debt increase in June 2025 suggests controlled borrowing, but monitoring debt servicing capacity is critical, given annual costs absorb ~40% of expenditures.

Strong tax revenue performance (TZS 2,339.7 billion in May 2025, 4.1% above target) supports debt servicing but requires sustained efforts to reduce reliance on budget support loans (15.2%)
