Executive Summary

Tanzania's external debt position has undergone profound transformation over five decades — from a debt crisis exceeding 107% of GNI in 1990, to partial relief following HIPC/MDRI initiatives in the mid-2000s, and then a worrying re-accumulation trend from 2015 onwards.

As of 2023, external debt stands at 44.6% of GNI — approaching the IMF/World Bank moderate risk threshold of 50%. Total debt service has ballooned to USD 2.24 billion annually — a seven-fold surge from USD 306 million in 2014. The debt-to-exports ratio has reached 519.4%, a figure that far exceeds the Debt Sustainability Framework's moderate threshold of 150%, signalling systemic vulnerability in Tanzania's export capacity relative to its debt obligations.

This analysis draws on World Bank International Debt Statistics (IDS) data to provide a comprehensive picture of Tanzania's debt sustainability position, the channels through which it impacts the current economy, and the policy actions needed to avert a renewed debt distress cycle.

⚠️

Critical Threshold Alert

Tanzania's debt-to-GNI of 44.6% is just 5.4 percentage points from the IMF moderate risk threshold of 50%. If the current trajectory continues, Tanzania could face sovereign risk reclassification within the next 3–5 years.


Historical Debt Trajectory (1980–2023)

The table below traces key debt sustainability indicators at major historical turning points, illustrating Tanzania's journey from debt distress to relief and back toward elevated risk.

1990

Peak Crisis: Debt Overhang at 107% of GNI

Tanzania registered one of the most severe debt overhangs in Sub-Saharan Africa. Debt-to-exports hit a catastrophic 1,181.9%, meaning the country owed more than 11× its annual export earnings. Debt service consumed 32.9% of all export receipts.

2001

HIPC Completion — Debt Relief Begins

Tanzania reached the HIPC (Heavily Indebted Poor Countries) completion point, triggering multilateral debt cancellation. Debt-to-GNI declined from 107.3% (1990) to 54.3% by 2000. Debt-to-exports halved from over 1,000% toward 500%.

2006

MDRI Relief — Transformational Debt Write-Off

The Multilateral Debt Relief Initiative (MDRI) slashed debt further, bringing debt-to-exports to just 231.2% by 2010 — the lowest in decades. Per capita external debt fell to a record low of USD 199.7 in 2010.

2015

Re-Accumulation Phase Begins

New infrastructure financing (SGR railway, energy projects) via non-concessional and commercial borrowing propelled debt-to-GNI back up to 38.9% in 2015, with total debt service surging from USD 306M (2014) to USD 469M (2015).

2023

Current Position: Approaching Danger Thresholds

Debt-to-GNI at 44.6%, debt-to-exports at 519%, and total debt service of USD 2.24 billion represent the most pressured position since the pre-HIPC era. The trajectory demands urgent policy response.

Impact on Tanzania's Current Economy

The re-escalation of debt service obligations has real, measurable consequences for Tanzanian households, public services, and macroeconomic stability. The table below summarizes the key transmission channels through which sovereign debt affects everyday life.

Fiscal Crowding-Out Effect

Every dollar paid in interest on Tanzania's external debt is a dollar unavailable for primary education, maternal healthcare, rural infrastructure, or climate adaptation. With interest payments rising 5× in nine years — from USD 113M to USD 660M — the opportunity cost in foregone social development is substantial and compounding.


Debt Sustainability Threshold Analysis

The IMF and World Bank use benchmark thresholds under the Debt Sustainability Framework (DSF) for Low Income Countries (LICs). Tanzania's current debt indicators relative to these thresholds reveal the country's current positioning — and the specific vulnerabilities that require urgent attention.

Tanzania vs IMF DSF Thresholds — 2023 Snapshot
Performance relative to DSF benchmarks (indexed: 100 = at threshold)

The Debt-to-Exports Red Flag

The most alarming indicator is debt-to-exports, which at 519% far exceeds the DSF moderate threshold of 150% and even the strong performer threshold of 200%. This signals that Tanzania's export base remains critically insufficient relative to its debt obligations — a vulnerability particularly acute given that tourism (a key export earner) remains susceptible to global shocks, and goods exports are dominated by low-value-added primary commodities.

📈

Debt/GNI Approaching the 40% Threshold

While Tanzania remained within the 40% debt/GNI threshold in 2015 (38.9%) and 2020 (39.5%), the 2023 figure of 44.6% has breached this marker — requiring active debt management to prevent further deterioration toward the 50% moderate risk boundary. At the current trajectory of ~1.5 percentage points per year, the 50% threshold could be breached by 2027.


Key Findings & Policy Implications

Six critical findings emerge from this analysis, each with direct policy implications for Tanzania's fiscal strategy, investment environment, and development trajectory.

01

Debt Service Hit Record USD 2.24B in 2023

Total annual debt service has reached a historic high, consuming a growing share of government revenues and export earnings.

→ Government must prioritize revenue mobilization (domestic tax collection) to reduce reliance on new borrowing for budget financing.
02

Debt/Exports Ratio of 519% Far Exceeds Safe Limits

At 3.5× the moderate DSF threshold of 150%, Tanzania's export base is structurally unable to service its debt without macroeconomic strain.

→ Export diversification is urgent — expanding manufacturing, value-added agriculture, and digital services exports is critical.
03

Per Capita Debt Rose 61% in 9 Years

From USD 322 in 2014 to USD 519 in 2023, each Tanzanian citizen's share of the country's external debt burden has grown significantly faster than income.

→ Future borrowing must be strictly tied to high-return productive investments that grow GNI faster than debt accumulation.
04

Interest Payments Up 5× Since 2014

Rising from USD 113M (2014) to USD 660M (2023), the interest bill reflects a shift toward costlier commercial and semi-concessional borrowing.

→ Negotiate longer maturities and lower interest rates; prioritize concessional financing over commercial debt in new agreements.
05

Debt/GNI Approaching 50% Threshold

At 44.6%, Tanzania is 5.4 percentage points from the IMF moderate risk threshold, which if breached could trigger sovereign risk reclassification and constrain future IFI borrowing.

→ Implement a formal Debt Management Strategy (DMS) with binding annual debt ceilings.
06

TZS Exchange Rate Amplifies Debt Costs

As debt-to-exports climbs, foreign currency demand for repayments weakens the Tanzanian Shilling, making dollar-denominated obligations more expensive in local currency terms — a self-reinforcing cycle.

→ Increase foreign exchange reserves and explore domestic currency borrowing to reduce currency mismatch risk.

Conclusion

Tanzania's debt sustainability position is at a critical crossroads. While the country successfully navigated the catastrophic debt crisis of the 1990s through HIPC/MDRI relief, the decade from 2014 to 2023 has seen a rapid re-accumulation of external obligations.

Total debt service has increased sevenfold in nine years, reaching USD 2.24 billion in 2023. The debt-to-GNI ratio of 44.6% is edging dangerously close to IMF sustainability thresholds, while the debt-to-exports ratio of 519% has been in structural violation of DSF benchmarks throughout the entire 2015–2023 period — a persistent red flag that speaks to Tanzania's underlying export competitiveness deficit.

The immediate economic impact manifests in compressed fiscal space — funds that could finance schools, hospitals, roads, and social protection are being channelled to foreign creditors. The depreciation pressure on the Tanzanian Shilling compounds this burden, as dollar-denominated repayments become increasingly expensive in local currency terms, creating a cyclical vulnerability.

If Tanzania does not implement disciplined debt management — combining revenue mobilization, export growth, and restraint on new commercial borrowing — the country risks entering a renewed debt distress cycle within the next five years. Proactive engagement with the IMF's Debt Sustainability Framework, development of a binding Debt Management Strategy, and accelerated export diversification are the most critical policy levers available to Tanzanian authorities today.

🔑

The Path Forward

Tanzania has successfully navigated debt crises before — the HIPC/MDRI experience demonstrates that with the right international frameworks and domestic policy discipline, debt overhang can be resolved. The difference now is that early action — before thresholds are breached — is far less costly than crisis management after the fact. Tanzania has a narrow window to act proactively.

📊 Data Source: World Bank International Debt Statistics (IDS). Analysis prepared by TICGL — Tanzania Investment and Consultant Group Ltd, February 2026.

Over six decades, Tanzania’s national debt has expanded from $0.2 billion in 1961 to $53.5 billion in 2025, marking an extraordinary 26,650% increase driven by evolving development priorities and policy shifts across six administrations. The current debt-to-GDP ratio of 48.2% remains within the IMF’s 55% sustainability threshold for low-income countries, while debt service accounts for 14.5% of government revenue—well below the 18% risk limit. Despite the rapid accumulation—averaging $6.25 billion per year under President Samia Suluhu Hassan—Tanzania’s debt remains largely sustainable, reflecting a strategy of leveraging borrowing for infrastructure, industrialization, and economic transformation.


Current Debt Profile (2025)

Tanzania's national debt stands at $53.5 billion as of 2025, representing a debt-to-GDP ratio of 48.2%—within internationally recognized sustainable limits. With debt service consuming 14.5% of government revenue, the country maintains manageable repayment obligations while pursuing ambitious development goals. The current debt level reflects 64 years of economic evolution, policy shifts, and strategic development financing across six presidential administrations.

Conclusion: Six Decades of Fiscal Evolution

Tanzania's national debt journey from $0.2 billion in 1961 to $53.5 billion in 2025 reflects the country's economic evolution through distinct phases:

The current debt position presents both opportunity and challenge. At 48.2% of GDP, Tanzania remains within sustainable limits with manageable debt service. However, the unprecedented $6.25 billion annual accumulation rate under President Hassan—nearly three times the Magufuli pace—raises important questions about long-term sustainability.

The critical test ahead is whether debt-financed infrastructure investments deliver the economic transformation necessary to justify the borrowing. If the Standard Gauge Railway, power projects, and industrial zones generate expected productivity gains and economic returns, Tanzania's debt strategy will be vindicated. If returns disappoint, the country risks approaching unsustainable levels that could constrain future development options.

Success requires moderating the debt accumulation pace, ensuring productive use of borrowed funds, strengthening revenue collection, and maintaining the strong economic growth that has characterized Tanzania's recent performance. With prudent management, Tanzania can leverage its current debt position for transformative development while preserving fiscal sustainability for future generations.

The lesson from six decades of debt evolution is clear: sustainable development financing requires balancing ambition with prudence, ensuring that each borrowed dollar contributes to building a more prosperous and self-reliant Tanzania.

The national debt profile from the Bank of Tanzania's Monthly Economic Review (September 2025) for August 2025 reveals a manageable 2.3% monthly increase to TZS 124.8 trillion (USD 47.2 billion), with external debt comprising 70.3% (TZS 87.7 trillion) and domestic at 29.7% (TZS 37.1 trillion). This structure—government-dominated (80.8% share) and increasingly concessional—implies sustained fiscal capacity to finance growth-oriented investments like infrastructure and social programs, supporting Q3 GDP estimates above 6% and low inflation (3.4%). As of early October 2025, debt remains at moderate risk of distress, with a debt-to-GDP ratio of ~46.3% projected for the year, per recent assessments, enabling Tanzania to leverage borrowing for Vision 2050's upper-middle-income goals amid resilient exports (e.g., gold and tourism). However, heavy external reliance (81% central government) exposes to FX risks from TZS fluctuations, despite recent appreciation (6.6% in August), underscoring needs for revenue diversification to cap service costs at ~20% of revenues.

These dynamics align with IMF and World Bank evaluations affirming moderate sustainability, with economic recovery projected to drive 6.0% GDP growth in 2025. Below, implications are detailed by category, linking to development enablers like credit expansion (16.2% y-o-y) and sectoral investments.

Overall Summary and Forward Outlook

August's debt rise implies a strategic tool for Tanzania's development: sustainable levels finance 6%+ growth and inclusion, with diversification mitigating risks in a resilient SSA economy (3.8% regional projection). External dominance funds recovery, while domestic deepening enhances stability. By year-end 2025, trends could hold debt at 46% GDP, but boosting revenues (16.5% GDP target) and non-concessional shifts will unlock 7% potential amid elections (October 28).

Between 2021/22 and 2025/26, Tanzania's debt service costs surged by 42–58%, from an estimated TZS 9–10 trillion to a confirmed TZS 14.22 trillion—now accounting for 25.2% of the national budget (TZS 56.49 trillion). Over this period, total public debt rose to approximately 46% of GDP, driven largely by external borrowing, which reached USD 33.9 billion in 2025/26 and remains 67.7% USD-denominated, exposing the country to exchange rate risks, especially following a 2.6% shilling depreciation in 2024/25. Domestic debt also expanded significantly to TZS 34.26 trillion, with the majority held by commercial banks and pension funds. Despite a stabilizing debt-to-GDP ratio and a manageable debt service-to-GNI ratio of 2.89% (2023), the growing reliance on non-concessional and foreign currency debt underscores fiscal vulnerabilities that require prudent debt management strategies to ensure long-term sustainability.

Escalating Service Costs

Tanzania's debt servicing landscape has undergone significant transformation over the past five years, reflecting the country's economic growth trajectory and evolving fiscal priorities. The most striking development is the substantial increase in debt service costs, which have risen from an estimated TZS 9-10 trillion in 2021/22 to TZS 14.22 trillion in 2025/26 – representing a 42-58% increase over the five-year period.

Key Performance Indicators at a Glance:

Detailed Year-by-Year Analysis

2021/22 Financial Year: Foundation Period

The 2021/22 period established the baseline for Tanzania's modern debt management framework. With debt service costs estimated at TZS 9-10 trillion, the government maintained a relatively moderate debt burden at 43.6% of GDP. The debt composition showed a balanced approach with domestic debt at 15.9% of GDP and external debt forming the larger portion. Notably, domestic arrears stood at a manageable 1.8% of GDP, indicating effective short-term debt management.

The present value debt-to-GDP ratio of 31% remained well below the 55% benchmark, positioning Tanzania in the low-to-moderate debt distress risk category. External borrowing was predominantly concessional, reducing the overall cost burden and exchange rate exposure.

2022/23 Financial Year: Strategic Expansion

The government allocated TZS 9.1 trillion for debt servicing within a total budget of TZS 44.4 trillion, with TZS 7.4 trillion successfully disbursed by April 2023. This period marked a strategic shift as public debt increased to 45.7% of GDP (46.7% including domestic arrears), reflecting increased infrastructure investment.

External debt composition rose to 63.3% of total debt, indicating a pivot toward international financing for development projects. The shift toward non-concessional borrowing began during this period, driven by infrastructure financing needs. Despite this increase, the present value debt-to-GDP ratio remained sustainable at 31.8%.

2023/24 Financial Year: Acceleration Phase

Debt servicing allocation reached TZS 10.48 trillion, representing a 15% increase from the previous year. This increase occurred within a Ministry of Finance budget of TZS 15.94 trillion, highlighting debt service as a major fiscal priority. Total public debt climbed to 47.36% of GDP, with external debt reaching USD 30.533 billion by July 2023.

The debt structure showed concerning trends with external debt comprising 73% of total obligations, significantly increasing Tanzania's exposure to exchange rate fluctuations. Total national debt reached approximately TZS 69.44 trillion in 2022, continuing its upward trajectory through 2023.

2024/25 Financial Year: Consolidation Efforts

Debt service costs are estimated at TZS 11-12 trillion within a national budget of TZS 49.35 trillion. External debt peaked at USD 32.89 billion in September 2024, subsequently reaching USD 33.905 billion by January 2025. The central government held 78.1% of external debt, indicating concentrated fiscal responsibility.

Domestic debt stabilized at TZS 32.62 trillion in September 2024, with Treasury bonds dominating at 78.9% of domestic obligations. The debt-to-GDP ratio showed signs of stabilization, with projections indicating a gradual decline to 40.84% by 2029, suggesting improved debt sustainability measures.

2025/26 Financial Year: Current Trajectory

The current budget allocation confirms TZS 14.22 trillion for debt servicing, including TZS 6.49 trillion specifically for interest payments. This represents the highest debt service allocation in the five-year period, occurring within a total budget of TZS 56.49 trillion. External debt stands at USD 33.905 billion, with the government holding 76.4% of these obligations.

Domestic debt has grown to TZS 34.26 trillion as of March 2025, primarily held by commercial banks (29-33%) and pension funds (26.5-27.6%). The USD-dominated debt structure (67.7-68.1%) continues to pose exchange rate risks, particularly given the 2.6% depreciation of the Tanzanian Shilling in 2024/25.

Key Observations

  1. Trend in Debt Service Costs: Debt service costs have increased steadily, from an estimated TZS 9–10 trillion in 2021/22 to TZS 9.1 trillion in 2022/23, TZS 10.48 trillion in 2023/24, an estimated TZS 11–12 trillion in 2024/25, and a confirmed TZS 14.22 trillion in 2025/26. This reflects growing borrowing, particularly external debt (73% of total debt in 2024), and larger budgets (TZS 44.4 trillion in 2022/23 to TZS 56.49 trillion in 2025/26). The 18–29% jump from 2024/25 to 2025/26 is driven by increased interest payments (TZS 6.49 trillion in 2025/26) and a higher debt stock.
  2. Debt Composition: External debt, predominantly USD-denominated (67.7–68.1%), reached USD 33.905 billion in 2025, exposing Tanzania to exchange rate risks, with a 2.6% shilling depreciation in 2024/25 increasing repayment costs. Domestic debt, mainly Treasury bonds (78.9% in 2024), rose from an estimated TZS 22.17 trillion in 2021/22 to TZS 34.26 trillion in 2025/26, held primarily by commercial banks (29–33%) and pension funds (26.5–27.6%).
  3. Sustainability: Tanzania’s debt-to-GDP ratio increased from 43.6% in 2021/22 to 47.36% in 2023/24, stabilizing at ~46% in 2024/25–2025/26, with a projected decline to 40.84% by 2029. The debt service-to-GNI ratio was 2.8915% in 2023, indicating moderate debt distress risk per IMF and World Bank analyses. However, reliance on non-concessional borrowing and USD exposure poses challenges, particularly with shilling depreciation.

Tanzania’s combined external debt of USD 35.51 billion and domestic debt of TZS 34,759.9 billion as of April 2025 supports critical sectors like infrastructure (21.5% of external debt) and social welfare (19.9%), driving economic growth projected at 6% for 2025. The IMF’s assessment of moderate external debt distress risk and a public debt-to-GDP ratio of 46.7% in 2022/23 (well below the 55% benchmark) indicate a sustainable debt profile, but rising borrowing and a TZS 284.3 billion budget deficit in March 2025 necessitate careful management to maintain economic resilience. Key issues include high debt servicing costs, exchange rate risks (TZS depreciated 3.9% to 2,684.41/USD), and limited revenue diversification. Strategies such as enhancing domestic revenue mobilization, prioritizing concessional borrowing, improving debt management, and diversifying exports can balance borrowing with sustainability, ensuring resilience against shocks while supporting Vision 2050’s growth targets.

Main Key Issues

  1. Debt Levels and Sectoral Support
    • Debt Composition: As of April 2025, external debt stands at USD 35,505.9 million, with 76.7% (USD 27,224.0 million) held by the central government and 23.3% (USD 8,278.1 million) by the private sector. Domestic debt is TZS 34,759.9 billion (USD ~12.95 billion at TZS 2,684.41/USD), up 9.2% from TZS 31,836.5 billion in April 2024. Combined, this equals ~USD 48.46 billion, or ~61.2% of 2024 GDP (USD 79.2 billion), higher than the 46.7% public debt-to-GDP ratio in 2022/23.
    • Sectoral Allocation: External debt supports transport and telecommunications (21.5%, ~USD 7,633.8 million), balance of payments and budget support (20.2%, ~USD 7,172.2 million), and social welfare and education (19.9%, ~USD 7,065.7 million). Domestic debt finances recurrent costs (e.g., TZS 833.3 billion for wages in March 2025) and development projects (TZS 1,406.7 billion, 41.7% of expenditure). These investments drive infrastructure (e.g., Standard Gauge Railway) and human capital, critical for 6% GDP growth.
    • Sustainability Metrics: The IMF’s moderate external debt distress risk reflects a debt-to-GDP ratio below 55% and reserves of USD 5.3 billion (4.3 months of import cover). However, TICGL note a rise in external debt from USD 32.09 billion in January 2025, signaling increased borrowing pressure. The debt service-to-export ratio (16.2% in 2024/25) remains manageable but requires vigilance.
  2. High Debt Servicing Costs
    • External Debt Servicing: With 67.4% of external debt (USD 23,931 million) in USD, servicing costs are estimated at ~USD 2.4 billion annually (assuming 6.7% average interest rate). In 2024/25, external debt service was USD 1,427.1 million, up from USD 1,224.3 million in 2023/24, straining reserves. Interest arrears are low (USD 78.0 million for central government, 0.2%), but private sector arrears (USD 1,637.0 million, 4.6%) indicate repayment challenges.
    • Domestic Debt Servicing: Domestic debt servicing reached TZS 890.9 billion in February 2025, with interest payments in March 2025 at ~TZS 300.0 billion (previous responses). This competes with development spending (TZS 1,406.7 billion), limiting fiscal space. TICGL note domestic debt servicing at TZS 2,364.3 billion in 2022/23, highlighting its fiscal burden.
    • Impact on Resilience: High servicing costs reduce funds for social programs and infrastructure, increasing reliance on borrowing (e.g., TZS 519.6 billion in Treasury bonds, previous responses). The Monthey Economic Review notes a fiscal deficit target below 3% of GDP, but the TZS 284.3 billion deficit in March 2025 suggests ongoing financing needs.
  3. Exchange Rate Risks and Currency Exposure
    • TZS Depreciation: The TZS depreciated 3.9% annually to TZS 2,684.41/USD in April 2025, increasing the cost of USD-denominated debt servicing by ~TZS 2,471.6 billion (23,931 million × 2,684.41 × 3.9%). The BoT’s interventions (USD 6.25 million sold in IFEM) and reserves mitigate volatility, but note a 29% TZS weakening from 2014–2024, amplifying debt costs.
    • Currency Composition: External debt’s 67.4% USD share, 16.8% Euro, and 6.3% Yuan expose Tanzania to currency risks, especially with a stronger USD (1 USD = TZS 2,655.59 in June 2025). Domestic debt in TZS avoids currency risk but faces inflation pressures (3.3% in March 2025, previous responses).
    • Trade Implications: Depreciation boosts export competitiveness (e.g., agriculture, 5.1% of external debt use), but higher import costs (USD 17,511.8 million in February 2025) and debt servicing strain reserves, reducing economic resilience. The current account deficit of USD 2,224.9 million, though improved by 18.6%, reflects external pressures (previous responses).
  4. Limited Revenue Diversification
    • Revenue Performance: Tax revenue in March 2025 reached TZS 2,603.3 billion (2% above target), but non-tax revenue underperformed at TZS 350.5 billion against TZS 522.4 billion, contributing to a TZS 3,090.8 billion total revenue (96.9% of TZS 3,190 billion target). The tax-to-GDP ratio (11.8% in 2022/23) is below the 15% Sub-Saharan Africa average, limiting debt repayment capacity.
    • Dependence on Taxes: Taxes constitute 84.2% of revenue (2,603.3 / 3,090.8 × 100), with non-tax TICGL (e.g., dividends, fees) contributing only 11.3% TICGL highlight inefficiencies in public enterprise dividends, constraining fiscal space for debt servicing and development spending.
    • Resilience Risks: Limited revenue diversification increases reliance on borrowing to fund the TZS 284.3 billion deficit, with domestic debt held by commercial banks (TZS 10,049.9 billion, 28.9%) and external loans (e.g., IMF’s USD 440.8 million). This heightens vulnerability to shocks, as seen in the private sector’s USD 1,637.0 million arrears.

Strategies to Balance Borrowing with Debt Sustainability

  1. Enhance Domestic Revenue Mobilization
    • Action: Increase the tax-to-GDP ratio to 13% by 2026 through broader tax base (e.g., informal sector, ~3 million taxpayers) and digital tax systems (EFDs). Target TZS 500 billion annually from non-tax TICGL by improving public enterprise dividends (e.g., TANESCO) and introducing carbon credits, covering ~17.6% of the March 2025 deficit (500 / 2,843 × 100).
    • Impact: Additional TZS 1,000 billion (tax + non-tax) could reduce borrowing needs, lowering domestic debt growth (9.2% in 2025) and servicing costs (TZS 890.9 billion in February 2025). This aligns with IMF recommendations for revenue reforms and supports social welfare spending (19.9% of external debt).
  2. Prioritize Concessional Borrowing
    • Action: Secure concessional loans (e.g., World Bank, IMF’s ECF USD 1,046.4 million) for 80% of new external borrowing, targeting USD 2 billion annually at <2% interest rates. Limit commercial loans (36.3% of external debt) to reduce servicing costs, saving ~USD 200 million annually (8% of USD 2.4 billion).
    • Impact: Concessional loans lower debt distress risk, freeing funds for infrastructure (21.5% of external debt) and maintaining reserves (USD 5.3 billion). This supports the Monthey Economic Review’s fiscal discipline and IMF’s moderate risk assessment.
  3. Improve Debt Management and Transparency
    • Action: Strengthen the Debt Management Office to monitor debt-to-GDP (46.7% in 2022/23) and debt service-to-export ratios (16.2%). Publish quarterly debt reports and hedge 20% of USD debt (USD 4.79 billion) against TZS depreciation, saving ~TZS 494.8 billion annually at 3.9% depreciation. Clear private sector arrears (USD 1 billion of USD 1.637 billion) to boost investor confidence.
    • Impact: Reduced arrears and transparency attract FDI (e.g., USD 1.4 billion for rail, supporting reserves and TZS stability (2,684.41/USD). This could fund TZS 1,406.7 billion in development spending, enhancing resilience against shocks like DRC conflict (USD 3).
  4. Diversify Exports to Boost Foreign Exchange
    • Action: Invest 5.1% of external debt (USD 1,810.4 million) and tourism receipts (USD 3,842.6 million) in agriculture and manufacturing (3.9% of external debt) to increase exports by 20% to USD 20.1 billion by 2027 (from USD 16,737.6 million in 2025). Promote value-added agriculture (e.g., processed coffee) under AfCFTA and agreements with UAE.
    • Impact: Higher exports reduce the current account deficit (USD 2,224.9 million) and USD demand, stabilizing TZS and reserves. A USD 1 billion export increase lowers the debt-to-export ratio by ~1%, supporting sustainability and resilience, aligning with Vision 2050.

Conclusion

Tanzania’s combined external (USD 38 billion) and domestic (TZS 35,768.5 billion) debt supports critical sectors but requires balanced borrowing to maintain sustainability, given a 46.7% debt-to-GDP ratio in 2025 and moderate IMF risk assessment. Key issues include high servicing costs (~USD 2.4 billion external, TZS 896.9 billion domestic), exchange rate risks (TZS 2,684.57/USD, 3.3% depreciation, limited revenue (TZS 3,060.8 billion in March 2025), and export dependence. Strategies like revenue mobilization (TZS 1,000 billion target), concessional borrowing (USD 2 billion), debt management, and export diversification (USD 20.1 billion by 2027) can reduce borrowing needs, stabilize TZS, and enhance resilience, supporting 6% GDP growth and Vision 2050.

Tanzania’s debt servicing costs have grown significantly from 2013 to 2024, reflecting the country’s rising debt stock and economic pressures. Debt servicing costs increased from an estimated USD 1.36 billion (TZS 3.71 trillion, 3.09% of GDP) in 2013 to USD 2.52 billion (TZS 6.87 trillion, 2.99% of GDP) in 2024, with a peak of USD 3.33 billion (TZS 9.09 trillion, 4.39% of GDP) in 2022. This rise, driven by a 184% increase in national debt (USD 14.93 billion to USD 42.36 billion) and an 8% TZS depreciation in 2023/24, has strained fiscal resources, with debt servicing consuming ~30% of recurrent expenditure (TZS 30.31 trillion) in 2022/23. Reliable data can be sourced from the Bank of Tanzania, IMF Debt Sustainability Analyses, and local reports like The Citizen.

Explanation of Figures:

Data on Debt Servicing Costs

Exact annual debt servicing costs for Tanzania are sparsely reported in public sources, with only a few specific figures available for the requested period. Below, I summarize the known data points and estimate others based on IMF and Bank of Tanzania (BoT) reports, which provide debt-to-GDP ratios, debt service ratios, and fiscal expenditure breakdowns.

Known Data Points

Estimation Methodology

  1. Debt Service Ratio: TICGL reports debt service at 2.89% of GNI in 2023. I’ll assume a range of 2.5–3.5% of GNI for other years, based on IMF DSAs indicating debt service typically ranges 5–7% of GDP for Tanzania.
  2. GNI Data: World Bank provides GNI (current USD) for select years (e.g., USD 69 billion in 2021, USD 75.94 billion in 2022). I’ll interpolate GNI for other years using GDP growth rates (4–6% annually, per IMF and World Bank) and assume GNI tracks GDP closely.
  3. External vs. Domestic Debt: External debt is 71.3% of total debt in 2023/24, with domestic debt at 28.7%. I’ll apply this ratio to estimate cost breakdowns, assuming external debt (concessional at 1–2%, commercial at 6–7%) and domestic debt (at 15–19% lending rates, per BoT and mortgage market data).
  4. Exchange Rate: Convert TZS to USD using 1 TZS = 0.000366972502112619 USD for consistency.

GNI Estimates

Using World Bank GNI data and GDP growth trends (4–6% annually), I estimate GNI as follows:

Explanation of Key Figures

  1. Total National Debt (USD Billion):
    • Sourced from Statista (2013, 2022–2024), IMF, and Trading Economics (interpolated for 2014–2021).
    • Shows a 184% increase from USD 14.93 billion in 2013 to USD 42.36 billion in 2024, driven by infrastructure borrowing (e.g., SGR, hydropower).
  2. Debt-to-GDP Ratio (%):
    • Sourced from IMF and Statista, rising from 32.68% (2013) to 47.30% (2024), indicating growing debt relative to economic output.
    • Reflects moderate sustainability risk per IMF’s 2023/24 DSAs (present value of debt-to-GDP at ~35% vs. 55% benchmark).
  3. Debt Servicing Cost (USD Billion and TZS Trillion):
    • 2022: Actual figure of TZS 9.09 trillion (USD 3.33 billion) from The Citizen, consuming ~30% of recurrent expenditure (TZS 30.31 trillion).
    • Other Years: Estimated using 2.5–3.5% of GNI, based on TICGL’s 2.89% for 2023 and IMF’s 5–7% of GDP range. Converted to TZS using 1 USD = 2,725.3 TZS.
    • Costs rose from USD 1.13–1.58 billion in 2013 to USD 2.10–2.94 billion in 2024, reflecting debt stock growth and higher domestic interest rates (15–19%).
  4. External Debt (% of GNI):
    • Available only for 2021 (41.04%) and 2022 (40.53%) from World Bank data.
    • External debt (71.3% of total in 2023/24) drives servicing costs, exacerbated by TZS depreciation (8% in 2023/24).

Tanzania’s external debt has shown a significant upward trend, reaching 35,039.8 USD Million in February 2025, up from 34,551.4 USD Million in January 2025, according to the Bank of Tanzania. This marks a month-on-month increase of approximately 488.4 USD Million or 1.41%. The external debt has grown steadily, averaging 20,062.78 USD Million from 2011 to 2025, with a record high of 34,936.5 USD Million in February 2025 and a low of 2,469.7 USD Million in December 2011. This reflects a substantial increase over the years, driven by investments in infrastructure, energy, and other development projects.

Tanzania’s External Debt in Context

Tanzania’s external debt is a critical indicator of its economic position within Africa and East Africa. To provide a comprehensive understanding, let’s compare Tanzania’s external debt to other African and East African countries, analyze its debt-to-GDP ratio, and explore the factors contributing to its debt profile.

Comparison with African Countries

The provided data lists external debt for several African countries, with figures converted to USD Million where necessary for comparison. Using the most recent data from the table and supplementing with additional context:

Tanzania’s external debt of 34,056 USD Million (Mar 2025) places it among the top 10 African countries for external debt, behind economic giants like South Africa, Egypt, and Nigeria, but ahead of smaller economies like Rwanda and Burundi. This reflects Tanzania’s growing economic ambitions but also its increasing reliance on external financing.

Comparison with East African Community (EAC) Countries

Within East Africa, Tanzania’s external debt is significant but not the highest. Key EAC countries include:

Tanzania’s external debt is comparable to Kenya’s, positioning it as a major borrower in the EAC. However, its debt-to-GDP ratio and risk profile are more favorable than some peers, as discussed below.

Debt-to-GDP Ratio and Sustainability

Tanzania’s external debt-to-GDP ratio provides insight into its debt sustainability. In 2023, Tanzania’s public debt (including external and domestic) was 46.87% of GDP, with external debt accounting for approximately 70.4% of total public debt (2023 data). Assuming a nominal GDP of 78 USD Billion in 2023 (projected to grow to 105.1 USD Billion in 2022, adjusting for inflation and growth), the external debt of 34,056 USD Million in March 2025 translates to roughly 32-35% of GDP, depending on GDP estimates for 2025.

Tanzania’s external debt-to-GDP ratio of ~32-35% is moderate compared to peers, and its public debt-to-GDP ratio of 46.87% (2023) is below the regional benchmark of 55% for low-income countries, indicating sustainable debt levels. The IMF’s 2024 Debt Sustainability Analysis (DSA) classifies Tanzania’s risk of external debt distress as low, supported by prudent fiscal policies and concessional borrowing.

Composition of Tanzania’s External Debt

As of December 2019, Tanzania’s external debt was USD 22.4 Billion (40% of GDP), with the central government holding 78%, the private sector 21%, and public corporations 0.4%. The debt is primarily owed to:

By currency, 68.9% of external debt is denominated in USD, followed by the Euro, which reduces exposure to currency fluctuations but increases repayment burdens when the Tanzanian shilling depreciates (8% depreciation in 2023).

Drivers of External Debt

Tanzania’s external debt growth is driven by:

  1. Infrastructure Investments: Large-scale projects like the Standard Gauge Railway (SGR), Dar es Salaam Port expansion, and energy projects (e.g., gas pipeline from Mnazi Bay to Dar es Salaam) require significant borrowing.
  2. Economic Diversification: Investments in mining (gold, nickel, graphite), manufacturing, and tourism to reduce reliance on agriculture.
  3. COVID-19 Response: Non-concessional borrowing during the pandemic to support the economy, increasing debt levels.
  4. Foreign Direct Investment (FDI): FDI rose to USD 922 Million in 2021, with projects like the Kabanga Nickel Project requiring external financing.

Risks and Challenges

Position in Africa and East Africa

Conclusion

Tanzania’s external debt of 34,056 USD Million in March 2025 reflects its ambitious development agenda but remains sustainable, with a debt-to-GDP ratio of ~32-35% and low distress risk. Compared to African peers, Tanzania’s debt is moderate, and within East Africa, it competes closely with Kenya while outperforming smaller economies like Rwanda and Burundi. Continued fiscal discipline, concessional borrowing, and economic diversification will be key to maintaining debt sustainability.

This table highlights Tanzania’s external debt of 34,056 USD Million (Mar 2025) as moderate within Africa, comparable to Kenya in East Africa, and sustainable relative to its GDP. Its debt-to-GDP ratio of ~32-35% is lower than peers like Rwanda (56.5%) and Angola (59.1%), positioning Tanzania favorably in terms of debt sustainability.
