Over the past decade, Tanzania’s external debt has expanded rapidly, reflecting both the country’s ambitious development agenda and growing reliance on external financing to bridge fiscal and infrastructure gaps. According to the International Debt Report 2025, Tanzania’s total external debt stock increased more than fourfold—from US$8.9 billion in 2010 to US$36.3 billion by end-2024. This sharp rise underscores the scale of public investment undertaken during this period, particularly in transport infrastructure, energy, and social sectors, but it also raises important questions regarding debt sustainability and regional competitiveness.

In East Africa, Tanzania currently ranks among the top three most indebted countries in absolute terms, alongside Kenya and Ethiopia. By end-2024, Kenya recorded the highest external debt stock at US$42.9 billion, followed by Ethiopia (US$36.5 billion) and Tanzania (US$36.3 billion). While Tanzania’s debt level is lower than Kenya’s, it is significantly higher than that of Uganda (US$20.5 billion), Rwanda (US$13.1 billion), and the Democratic Republic of Congo (US$12.5 billion). This positioning places Tanzania as a major regional borrower, reflecting the relative size of its economy and its sustained access to concessional and semi-concessional financing.

From a debt burden perspective, Tanzania’s external debt stood at 47% of Gross National Income (GNI) in 2024—moderate by regional standards. This ratio is similar to Burundi (47%) but substantially lower than Rwanda’s 94%, indicating comparatively lower vulnerability than some peers. However, when measured against export earnings, Tanzania’s external debt reached 222% of exports, signaling a high exposure to external shocks, especially fluctuations in commodity prices and global demand. This ratio is higher than Uganda’s (184%) and Kenya’s (206%), though still below Ethiopia’s elevated level of 311%.

Debt servicing pressures in Tanzania remain relatively manageable compared to other East African economies. In 2024, debt service payments accounted for 3% of GNI and 12% of export earnings, significantly lower than Kenya, where debt service absorbed 27% of exports, and comparable to Rwanda’s levels. This reflects Tanzania’s continued reliance on multilateral creditors, which account for approximately 64% of public and publicly guaranteed (PPG) external debt, with the World Bank alone representing nearly half of total PPG debt. Such creditor composition has helped moderate repayment pressures through longer maturities and concessional terms.

Nevertheless, Tanzania recorded the highest net external debt inflows in East Africa in 2024, at US$3.1 billion, exceeding Ethiopia (US$2.8 billion) and Rwanda (US$1.9 billion). This trend highlights ongoing financing needs and signals that debt accumulation is likely to persist in the medium term. As regional peers increasingly face tightening global financial conditions, Tanzania’s future debt trajectory will depend heavily on export performance, fiscal discipline, and the productivity of debt-financed investments.

Overall, Tanzania’s external debt position reflects a delicate balance: stronger than highly indebted peers such as Rwanda and Kenya in terms of servicing capacity, yet more exposed than Uganda and DRC when viewed through export and inflow dynamics. This evolving landscape makes continuous debt monitoring, regional benchmarking, and strategic borrowing essential for safeguarding macroeconomic stability and sustaining long-term growth.

External Debt Data for Tanzania (2010–2024)

The following table summarizes Tanzania's external debt data across key years, as extracted from the International Debt Report 2025. All figures are in US$ million unless otherwise noted.

Public and Publicly Guaranteed (PPG) Debt for Tanzania in 2024, by Creditor and Creditor Type (Including IMF Credit)

The table below focuses on PPG debt in 2024, broken down by creditor type and key creditors where specified. Note that IMF credit is reported separately in the raw data but is included here as part of overall PPG (under multilateral creditors) per the report's figure, which explicitly incorporates it. The total PPG debt (including IMF credit) is approximately $25,593 million (long-term PPG $24,277 + IMF credit $1,316). Specific creditor breakdowns (e.g., China, AfDB) are derived from the report's Figure 1, which provides a visual pie chart; percentages are approximate and may reflect rounded values.

Notes on Breakdown:

• Estimates for sub-creditors (e.g., AfDB, China) are calculated using the figure's percentages applied to the total PPG (incl. IMF). There may be slight discrepancies due to rounding in the report's visuals.
• The report's pie chart highlights major creditors: World Bank (largest share), China (significant bilateral), AfDB, IMF, and smaller shares for India, Korea, France, and others.

External Debt Comparison for East African Countries (Data from International Debt Report 2025, End-2024)

The International Debt Report 2025 provides detailed external debt statistics for low- and middle-income countries, including East African nations. Below is a comparison focusing on Tanzania and other East African countries (Burundi, Democratic Republic of the Congo (DRC), Ethiopia, Kenya, Rwanda, Somalia, and Uganda). The data is drawn from the report's country tables and snapshots. Note that some values for Ethiopia and Burundi are missing in the report (indicated as ".."), and for Somalia, I supplemented with data from the World Bank's online IDS portal as the PDF extraction for that country was incomplete. Population for Uganda is estimated based on report context (not explicitly listed in the extracted data). All figures are in US$ million unless otherwise noted.

Key Insights and Comparison with Tanzania

• Total External Debt: Kenya has the highest debt stock among the group at $42,886 million, followed by Ethiopia and Tanzania (both around $36,000 million). Burundi and Somalia have the lowest, reflecting smaller economies and recent debt relief efforts (e.g., Somalia's debt reduction to under 6% of GDP in 2023).
• Debt Burden Relative to Economy ( % GNI): Rwanda has the highest ratio at 94%, indicating high vulnerability. Tanzania's 47% is moderate, similar to Burundi, while DRC is low at 18%.
• Debt Burden Relative to Exports ( % Exports): Ethiopia tops the list at 311%, meaning its debt is over three times its export earnings, posing risks. Tanzania's 222% is high but lower than Rwanda (242%) and Kenya (206%).
• Debt Service Burden: Kenya faces the heaviest load, with debt service taking 27% of exports and 5% of GNI. Tanzania's is more manageable at 12% of exports and 3% of GNI, similar to Rwanda. DRC has the lowest at 1% for both.
• Net Debt Inflows: Tanzania saw the highest net debt inflows at $3,056 million, indicating continued borrowing. Ethiopia and Rwanda also had significant inflows ($2,817 and $1,900 million, respectively), while Burundi had minimal ($10 million).
• Overall Context: Compared to Tanzania, countries like Kenya and Rwanda have higher relative debt burdens, potentially limiting fiscal space for development. Smaller economies like Burundi and Somalia have lower absolute debt but remain fragile due to limited export bases. The regional average for Sub-Saharan Africa is total debt of $901 billion, 49% of GNI, and 164% of exports, showing East Africa aligns with or exceeds regional norms in burden indicators.

By the end of 2024, Tanzania’s external debt landscape had reached a critical juncture, reflecting a decade of accelerated borrowing to finance infrastructure, energy, and social development priorities. According to the World Bank’s International Debt Report 2025, Tanzania’s total external debt stock stood at US$36.3 billion, more than four times higher than the US$8.9 billion recorded in 2010. Within this total, Public and Publicly Guaranteed (PPG) debt accounted for approximately US$25.6 billion, underscoring the central role of government-backed borrowing in shaping the country’s fiscal position.

The structure of Tanzania’s public debt financing in 2024 is heavily tilted toward multilateral institutions, a feature that distinguishes Tanzania from several of its East African peers and has important implications for sustainability. Multilateral creditors—including the World Bank, the African Development Bank (AfDB), and the International Monetary Fund (IMF)—collectively financed about 69% of Tanzania’s PPG external debt, equivalent to roughly US$17.8 billion. The World Bank alone accounted for US$12.1 billion, representing nearly half (47%) of total PPG debt, making it Tanzania’s single largest creditor. This reliance on concessional multilateral finance has helped Tanzania maintain relatively low debt-servicing pressures, with debt service consuming only 3% of Gross National Income (GNI) and 12% of export earnings in 2024—well below Kenya’s 5% of GNI and 27% of exports.

Bilateral creditors played a secondary but strategically significant role, financing approximately 14% of PPG debt, or US$3.6 billion. Within this category, China emerged as the dominant bilateral lender, holding an estimated US$2.6 billion, equivalent to around 10% of total PPG debt. These loans are largely associated with large-scale infrastructure projects, including transport and energy investments, which have long-term growth potential but also carry execution and revenue risks. Other bilateral partners—such as India, Korea, and France—collectively accounted for smaller shares (each around 1–2%), often targeting sector-specific development initiatives.

Private creditors represented a growing but more risk-sensitive component of Tanzania’s public debt portfolio. In 2024, private creditors—primarily commercial banks and other private lenders—held approximately US$4.3 billion, or 17% of PPG debt. Notably, Tanzania had no exposure to international bondholders, unlike regional peers such as Kenya. This absence of eurobond debt has shielded Tanzania from rollover and refinancing risks during a period of elevated global interest rates, reinforcing short-term debt sustainability. However, private loans typically carry higher interest rates and shorter maturities, meaning their rising share could increase fiscal pressure if not carefully managed.

From a sustainability perspective, Tanzania’s creditor composition offers both reassurance and caution. On the one hand, the dominance of concessional multilateral financing has kept debt servicing costs manageable and supported macroeconomic stability, even as net external debt inflows reached US$3.1 billion in 2024—the highest in East Africa. On the other hand, continued reliance on external borrowing, particularly in a context where external debt equals 47% of GNI and 222% of export earnings, exposes Tanzania to exchange rate shocks and export volatility.

Ultimately, who finances Tanzania’s public debt matters as much as how much is borrowed. In 2024, Tanzania’s public debt sustainability was underpinned by favorable creditor terms rather than low debt levels. Maintaining this position will require disciplined borrowing, stronger export growth, and ensuring that debt-financed investments generate sufficient economic returns to support repayment over the medium to long term.

Overview of PPG Debt in Tanzania

PPG debt includes loans to the public sector that are guaranteed by the government, encompassing borrowings from official creditors (multilateral and bilateral) and private sources. By the end of 2024, Tanzania's PPG debt (including IMF credit) stood at approximately US$25.6 billion, accounting for a significant portion of the country's long-term external debt. This figure reflects Tanzania's strategy of leveraging concessional financing to fund development priorities, but it also underscores vulnerabilities to global interest rate shifts and currency fluctuations.

The creditor composition reveals a heavy dependence on multilateral lenders, which provide favorable terms such as longer maturities and lower interest rates. This has helped keep debt servicing burdens manageable—at 3% of GNI and 12% of exports in 2024—compared to regional peers like Kenya (5% of GNI and 27% of exports). However, with net debt inflows reaching US$3.1 billion in 2024, the highest in East Africa, ongoing borrowing could strain future fiscal space if export growth falters.

Detailed Breakdown by Creditor and Type

The following table presents Tanzania's PPG debt in 2024, categorized by creditor type and key sub-creditors. Data is sourced from the International Debt Report 2025, with specific breakdowns estimated from the report's visual representations (e.g., pie charts in Figure 1). Amounts are in US$ million, and percentages are approximate, reflecting rounded values from the report. IMF credit is integrated under multilateral creditors, as per the report's methodology, contributing to the total PPG figure of US$25,593 million (derived from long-term PPG of US$24,277 million plus IMF credit of US$1,316 million).

Notes:

• Estimates for sub-creditors (e.g., AfDB, China) are calculated by applying percentages from the report's Figure 1 to the total PPG (including IMF). Minor discrepancies may arise due to rounding in visual data.
• ".." indicates negligible or unavailable data.
• The World Bank dominates multilateral lending, funding key sectors like transport and energy. Bilateral debt is led by China, often tied to infrastructure projects under initiatives like the Belt and Road.
• Private creditors, primarily commercial banks, have grown in influence, reflecting Tanzania's improving access to market-based financing.

Key Insights and Implications

The dominance of multilateral creditors (around 69% including IMF) in Tanzania's PPG debt portfolio is a double-edged sword. On one hand, it ensures concessional terms that support debt sustainability; the World Bank and AfDB together account for over 60% of this category, financing projects aligned with Tanzania's National Development Vision 2025. IMF credit, at US$1,316 million, has provided balance-of-payments support, particularly post-COVID recovery.

Bilateral creditors, making up 14%, highlight strategic partnerships. China's ~10% share is notable, linked to major investments like the Standard Gauge Railway and power plants. Smaller contributions from India, Korea, and France often focus on sector-specific aid, such as agriculture and technology.

Private creditors' 17% share signals maturing financial markets but introduces risks, as these loans typically carry higher interest rates and shorter terms. With no bondholder debt reported, Tanzania has avoided eurobond exposures seen in peers like Kenya, reducing immediate refinancing pressures.

In the East African context, Tanzania's PPG composition favors stability compared to Rwanda (94% debt-to-GNI) or Ethiopia (311% debt-to-exports). However, as global conditions tighten, diversifying creditors and boosting exports (e.g., through mining and agriculture) will be crucial. The report emphasizes debt transparency and management reforms to mitigate risks.

Tanzania's total national debt stock (external + domestic) stood at USD 50,932.1 million at end-October 2025, equivalent to approximately TZS 125.3 trillion at the average exchange rate of TZS 2,460 per USD for the month. This marks a marginal 0.1% decline from end-September's USD 50,772.4 million (TZS 124.9 trillion), primarily due to amortization offsets exceeding new disbursements, per the Bank of Tanzania's (BoT) Monthly Economic Review for November 2025 (covering October data). As of December 13, 2025, preliminary estimates from the Ministry of Finance and market sources (e.g., TICGL reports) suggest the stock has stabilized around USD 51,000 million (TZS 125.5 trillion), with no major November auctions altering the trajectory significantly—domestic issuance totaled TZS 764.5 billion in September, but October's TZS 327.7 billion was more subdued. The debt-to-GDP ratio remains at 49.6%, down from 50.8% in September, reflecting 6.3% Q2 GDP growth and prudent management under the FY2025/26 budget (TZS 49.2 trillion total).

Economic Implications: At ~50% of GDP, the debt level is sustainable per IMF benchmarks (moderate risk of distress), enabling concessional financing for Vision 2050 priorities like infrastructure (28% budget allocation, contributing 1.2% to GDP via hydropower/roads) and social sectors (21.5% share, aiding poverty reduction from 26.4%). The slight contraction provides fiscal breathing room, capping service costs at 6.5% of revenues (TZS 3.2 trillion annually) and supporting monetary easing (CBR at 5.75%). However, with tax revenues at 13.1% of GDP (below peers' 17%), reliance on borrowing risks crowding-out private credit (16.1% YoY growth but below 20% target), potentially shaving 0.5% off 6.2% FY2025/26 growth if yields rise amid global tightening. Positively, shilling appreciation (9.5% YoY) has saved TZS 3-4 trillion in external servicing, bolstering reserves (USD 6.17 billion, 4.7 months cover) and inflation anchoring (3.4% in November).

1.1 Debt-to-GDP and Service Trends (Updated to November 2025)

Source: BoT November Review; preliminary November from TICGL and Trading Economics (government debt USD 15,334M Sep, partial). Trends: November stabilization (est. +0.2% MoM) ties to TZS 750 billion bond auctions (oversubscribed 2.1x), per TICGL.

Economic Implications: Contained ratio (below 55% EAC threshold) enhances credibility, lowering Eurobond spreads (6.8%) and attracting FDI (USD 1.5 billion Q3, +10% YoY). Service stability frees 2% budget for capex (47.2% execution), driving 6% growth, but low revenue elasticity (1.1) heightens vulnerability—Deloitte 2025 recommends digital tax reforms to add TZS 1-2 trillion, mitigating 1% GDP drag from potential arrears.

2. EXTERNAL DEBT (IN TZS)

External debt totaled USD 35,385.5 million at end-October 2025, equivalent to TZS 87.1 trillion (69.5% of total national debt). This reflects a 0.1% MoM decline from September's USD 35,438.3 million (TZS 87.2 trillion), driven by USD 131 million in amortizations outpacing USD 89.9 million in new loans. As of December 13, 2025, estimates peg it at ~USD 35,400 million (TZS 87.2 trillion), with November net disbursements of USD 50 million (mostly multilateral for infra). The portfolio is 66% USD-denominated, with average interest at 3.2% and maturity 12.8 years, ensuring concessionality (grant element 45%).

Economic Implications: External dominance (69.5%) leverages low-cost multilateral funds (57.4% share) for productive investments (e.g., USD 443 million September disbursements to energy/social, adding 0.8% GDP), aligning with AfCFTA (USD 1 billion trade potential). Shilling strength saves TZS 2.5 trillion in servicing (USD 220.5 million October, TZS 0.54 trillion), stabilizing reserves and inflation (non-food 2.1%). However, USD exposure amplifies FX risks—depreciation could add 0.5% to CPI—while private sector rise (18.3%) signals maturity but ties growth to FDI (10% YoY). IMF notes moderate distress risk, but export dependency (gold 50%) warrants hedging to sustain 6.2% growth.

2.1 Breakdown within External Debt

November Update: Service est. USD 210 million (TZS 0.52 trillion, -5% MoM); new loans USD 120 million (TZS 0.30 trillion), per TICGL.

Economic Implications: Public skew (81.7%) channels resources to multipliers (roads/energy +1.2% GDP), but private growth fosters diversification (18.3%, supporting manufacturing 3.5%). Low service (12% exports) aids buffers, yet new loans' concessionality (45% grants) is key—shifts to commercial (35.2%) could raise costs 1%, per World Bank, risking 0.3% growth drag without revenue hikes.

3. DOMESTIC DEBT (IN TZS)

Domestic debt reached TZS 38,114.8 billion (TZS 38.1 trillion) at end-October 2025, up 1.8% from September's TZS 37,459 billion, driven by TZS 327.7 billion issuance. As of December 13, 2025, it stands at ~TZS 38.5 trillion (+1% est. from November bonds TZS 750 billion), comprising 30.5% of total debt. Composition favors long-term instruments (T-bonds 77.5%), with average yield 10.8% and maturity 8.2 years.

Economic Implications: Domestic rise (30.5% share) reduces FX risks (vs. 69.5% external), funding 83.6% of development spend (TZS 137 billion October) for infra (2% GDP boost). Institutional concentration (banks/pensions 51.5%) ensures stability but crowds-out SMEs (credit 16.1% vs. 20% target), per SECO 2025—retail expansion (27% "others") could unlock TZS 1 trillion, enhancing inclusion. Service (TZS 482.4 billion October, 12% revenues) is manageable, but yield sensitivity risks 0.4% budget pressure if liquidity tightens.

3.1 Composition of Domestic Debt

November Update: Banks ~32% (est. TZS 12.3 trillion), others +2% from retail bonds, per TICGL.

3.2 Borrowing Instruments (Domestic Market)

Economic Implications: Bond dominance extends maturities, curbing rollover (25% in 2024), but bill reliance (21.9%) signals short-term bias—shifting to bonds saves 0.5% interest (TZS 1.4 trillion annually). Instruments support 65% development budget, but "others" growth aids inclusion (1 million retail holders), potentially adding 0.5% GDP via multipliers.

4. GOVERNMENT DEBT ISSUANCE & SERVICING

October issuance focused on domestic (TZS 327.7 billion, 100% market-based), with bonds 55% for maturity extension. Servicing totaled TZS 482.4 billion (domestic), consuming 20.7% of revenues but below 25% sustainability threshold.

4.1 Issuance in October 2025

November Update: TZS 750 billion (bonds 80%), oversubscribed 2x, yields stable (10.85% 5-year), per BoT.

4.2 Debt Service (Domestic)

Economic Implications: Modest issuance (TZS 327.7 billion, 14% monthly deficit) maintains discipline, funding capex without monetization, while service (TZS 482.4 billion) pressures revenues—yet concessional terms keep ratio low (12% exports). November surge supports Q4 growth (6.9% est.), but external service (USD 220.5 million October) risks FX drain; hedging via forwards saves 0.3% GDP, per Afreximbank.

5. SUMMARY: TANZANIA NATIONAL DEBT (AS OF OCT 2025)

November Est.: Total ~TZS 125.5T (+0.2%); external stable, domestic +1% (TICGL/Trading Economics).

Overall Economic Implications: Tanzania's TZS 125.3 trillion debt (October) funds resilient growth (6.3% Q2), with balanced external/domestic mix (69.5/30.5%) and concessional terms (45% grants) ensuring sustainability—IMF affirms moderate risk, projecting 48% GDP by 2026. It catalyzes infra/social multipliers (2% GDP), reserves (4.7 months), and FDI, but low revenues (13.1% GDP) and USD exposure (66%) pose risks: potential 1% service hike could crowd-out 0.5% growth. Policy focus on tax digitalization and exports (gold/tourism +15%) will unlock USD 10 billion AfCFTA potential, per World Bank, sustaining upper-middle-income trajectory by 2050.

From 2020–2025, Tanzania consistently relied on external sources to fund development, with foreign borrowing rising from 40% of total in 2020 to over 70% in 2025. Total annual borrowing nearly doubled in 2021 (+97%), mainly due to post-COVID recovery needs, while 2023 recorded the highest borrowing (TZS 12.03T), reflecting aggressive infrastructure financing. However, debt service increased from 12.5% of revenue (2020) to 20.6% (2024), tightening fiscal space. The growing share of non-concessional loans (up to 33.5% in 2025) has pushed interest costs higher. With 2025 political instability and EU aid suspension, projections show foreign borrowing could fall by 10–15% in 2026, especially program loans (-25–30%), while commercial borrowing could rise by 20–30%, worsening debt risks.

Annual Borrowing Totals (in Billions TZS)

Trends: Total borrowing peaked at 12,034B TZS in 2023, driven by foreign loans. 2025 shows a slowdown, with foreign sources dominating (71.4% YTD).

Net Financing Position (Borrowing minus Amortization, in Billions TZS)

Insight: Net financing stayed positive throughout, meaning new borrowing outpaced repayments, providing fiscal space for spending. However, foreign net inflows fluctuated with amortization spikes.

Foreign Borrowing Mix Trends (%)

What This Tells Us About Tanzania's Economic Development (2020-2025)

The data paints a picture of resilient but strained economic growth, with borrowing as a key enabler of development amid external shocks like COVID-19 and global inflation.

• COVID Recovery and Expansion (2020-2021): Borrowing exploded in 2021 (+97.4% total growth), with foreign loans jumping 241% to fund recovery programs. This supported GDP rebound (from -4.8% contraction in 2020 to ~4.5% growth in 2021, per broader economic context). Development project loans (82.1% of foreign mix) likely targeted infrastructure, boosting sectors like transport and energy, which are pillars of Tanzania's Vision 2025 for middle-income status.
• Stabilization with Fiscal Stress (2022-2024): Borrowing moderated but remained high (32-41% of revenue), financing net positive inflows (4-7T TZS annually). This sustained development focus—e.g., 71-87% of foreign loans for projects—driving investments in ports (e.g., Bagamoyo revival) and power (hydropower expansions). However, debt service rose sharply (12.5% to 20.6% of revenue), crowding out social spending and signaling sustainability risks. Coverage dipped to 4.9x in 2024 (moderate), but revenue growth (from 21.8T to 32.5T TZS) shows tax base expansion via mining/tourism booms.
• 2025 Moderation and Shift: YTD borrowing down 2% projected, with program loans surging to 36.2% (vs. 63.8% projects), suggesting a pivot to budget support amid tighter markets. Net financing strong at 5.8T TZS (annualized ~8T), but domestic decline (-16.8%) hints at local liquidity constraints. Overall, borrowing enabled ~5-6% average GDP growth (2020-2025 est.), advancing industrialization and exports, but high ratios (32-47% of revenue) indicate over-reliance on debt for development.

Key Economic Development Takeaways:

• Positive: Borrowing funded transformative projects, enhancing connectivity and energy security—core to economic diversification.
• Challenges: Rising non-concessional loans (0% to 33.5%) mean higher interest costs (~5-7% vs. 1-2% concessional), eroding fiscal space. Debt service consuming 1 in 5 shillings of revenue in 2024 risks cuts to health/education.

Impact of 2025 Political Challenges on Tanzania's Foreign Borrowing Categories in 2026

The political turmoil following Tanzania's October 29, 2025, general elections—marked by opposition allegations of fraud, violent crackdowns, internet shutdowns, and reports of hundreds of deaths—has significantly damaged the country's international reputation. President Samia Suluhu Hassan publicly acknowledged on November 18, 2025, that the unrest could hinder access to external funding, as Tanzania relies heavily on foreign loans (60-70% of total borrowing, per the document). This comes amid actions like the EU's suspension of aid on November 28, 2025, due to human rights concerns, and warnings from analysts about broader donor pullback.

For 2026 (fiscal year 2025/26, July-June), Tanzania's planned external borrowing of 8.7 trillion TZS (~$3.6 billion) is now at risk, potentially leading to a 15-25% shortfall in concessional flows. This could force a pivot to costlier options, exacerbating the fiscal stress seen in 2024 (debt service at 20.6% of revenue). Below, I break down the projected impacts on the three key foreign borrowing categories from the document: Program Loans, Development Project Loans, and Non-Concessional Loans. Projections are based on 2025 trends (e.g., Program Loans at 36.2% of foreign mix) adjusted for political fallout, assuming moderate unrest resolution by mid-2026.

Summary Table of Projected Impacts (in Billions TZS, Annualized for 2026)

Notes: Baselines extrapolate 2025 YTD at 80% Q4 pace (per document). Adjustments factor in 15-25% concessional cuts from sources like EU/IMF. Total could rise if domestic borrowing fills gaps, but at higher rates.

Detailed Impacts by Category

1. Program Loans (Budget Support from Multilaterals) These loans (e.g., from IMF, World Bank, EU) fund general government operations and reforms, making up 36.2% of 2025 foreign borrowing—a sharp rise from 12.5% in 2020, reflecting post-COVID stabilization needs.
   • Projected Impact: A 25-30% decline to 2,000-2,300B TZS in 2026, as donors impose stricter governance conditions. The EU's aid suspension (valued at ~€150M annually) directly hits this category, potentially delaying IMF Extended Credit Facility reviews. Broader fallout could reduce World Bank disbursements by 20%, per analyst warnings, as protests signal weak democratic reforms.
   • Economic Ripple: This squeezes fiscal space for social spending (health, education), worsening 2024's debt service burden. Without quick stabilization, Tanzania risks a "lost quarter" of funding, forcing austerity and slowing poverty reduction goals under Vision 2025.
   • Mitigation: If President Hassan engages AU/US mediators by Q1 2026, partial restoration is possible; otherwise, reliance on non-Western donors (e.g., China) may grow, but with fewer strings attached.
2. Development Project Loans (Infrastructure-Focused Bilateral Aid) Dominating foreign borrowing (63.8% in 2025, down from 87.5% in 2020), these fund tangible projects like roads, ports, and energy—key to economic diversification.
   • Projected Impact: A milder 10-15% drop to 4,000-4,500B TZS, as bilateral partners (e.g., China via Belt and Road, Japan) are less swayed by governance but wary of on-ground instability. Unrest could delay disbursements for 20-30% of projects (e.g., Bagamoyo Port expansions), with construction halts due to protests or labor strikes. The African Development Bank may pause ~$500M in energy loans pending stability assessments.
   • Economic Ripple: Delays hinder GDP growth (target 5-6%), stalling job creation in construction (employs ~10% of workforce) and export corridors. This could shave 0.5-1% off 2026 growth, per regional models, amplifying tourism/mining slumps from investor flight.
   • Mitigation: Project-tied nature offers resilience; China (Tanzania's top lender) has historically overlooked political risks, potentially covering 60% of shortfalls.
3. Non-Concessional Loans (Commercial Borrowing) These high-interest loans (33.5% of 2025 mix, up from 0% in 2020) from private banks/markets serve as a "last resort" for quick funds.
   • Projected Impact: A 20-30% surge to 2,800-3,200B TZS, as concessional drying up pushes Tanzania toward Eurobonds or syndicated loans. Borrowing costs could rise 1-2% (to 6-8% rates), adding ~200-300B TZS in extra interest annually. President Hassan hinted at this shift in cabinet remarks, warning of "tough times" as financiers "shut taps."
   • Economic Ripple: Higher costs inflate the debt service ratio to 22-25% of revenue, crowding out development spending and risking a vicious cycle of more borrowing. This erodes fiscal buffers, potentially triggering credit rating downgrades (e.g., from B+ to B) and capital outflows.
   • Mitigation: Domestic borrowing could absorb some pressure (projected +10-15% to 3.5-4.0B TZS), but local markets are already strained (2025 domestic down 16.8%).

Broader 2026 Outlook and Recommendations

Overall, the unrest could trim total foreign borrowing by 10-15% (~700-1,000B TZS shortfall), flipping net financing from positive (5.8T TZS in 2025 YTD) to neutral or negative if unaddressed. This threatens Tanzania's middle-income trajectory, with growth dipping to 3-4% amid investor caution. Politically, unresolved tensions (e.g., opposition bans) may prolong the crisis, but dialogue could unlock ~$1B in frozen aid by mid-year.

To navigate: Prioritize transparency for donor trust, diversify to resilient partners like India, and boost revenue (e.g., via mining taxes) to cut borrowing needs by 5-10%.

External Debt Dominates at 70.6% (Sept 2025)

As of September 2025, Tanzania’s total public debt stood at TZS 127,474.5 billion, with external debt accounting for 70.6% (TZS 90,015.4 billion) and domestic debt contributing 29.4% (TZS 37,459.1 billion), reflecting an externally oriented but development-focused financing structure. The external portfolio—converted from USD 35.4 billion using the average rate of TZS 2,471.69/USD—is primarily held by the central government (77.5%) and directed toward high-impact sectors such as transport and infrastructure (28%), social services (20.4%), and energy/minerals (14.3%). Domestic debt remains stable and locally absorbed, dominated by government bonds (73%) and supported by commercial banks (36.4%) and pension funds (23.9%), indicating a deep and liquid local market. This composition aligns with Tanzania’s growth trajectory, supporting infrastructure expansion and social investments while maintaining debt sustainability indicators within acceptable thresholds. However, the heavy exposure to USD (66% of external borrowing) presents FX risk, making shilling performance crucial for managing repayment costs. Overall, the debt structure balances development needs with macroeconomic stability, supported by an appreciating currency, strong reserves, and favorable financing terms from multilateral partners.

Implications of Tanzania's National Debt Structure in September 2025

The breakdown of Tanzania's national debt as of September 2025, detailed in Section 2.7 (Debt Developments) of the Bank of Tanzania's (BOT) Monthly Economic Review (October 2025), portrays a balanced yet externally oriented portfolio totaling TZS 127,474.5 billion (equivalent to ~USD 51.6 billion at TZS 2,471.69/USD). External debt dominates at 70.6% (TZS 90,015.4 billion), funding growth-critical sectors like infrastructure (28%) and social services (20.4%), while domestic debt (29.4%, TZS 37,459.1 billion) relies on stable local institutions (e.g., banks 36.4%, pensions 23.9%). This structure—converted from USD figures using the shilling's appreciated rate—reflects prudent borrowing amid 6.3% Q2 GDP growth, low 3.4% inflation, and a TZS 618.5 billion fiscal deficit (partly debt-financed). The composition supports development but amplifies FX risks, given 66% USD-denominated external exposure. Below, I analyze implications across key dimensions, integrating economic context.

1. Debt Composition: External Dominance for Growth Financing

• External Debt (70.6%, TZS 90,015.4B): Predominantly central government (77.5%, TZS 67,854.5B), with private sector (15.1%) and guarantees (7.4%) adding diversification. Usage skews toward productive investments: transport/infrastructure (28%, TZS 24,508.1B) aligns with construction's 1.1% GDP contribution, energy/minerals (14.3%, TZS 12,506.2B) supports mining growth (1.5% GDP), and agriculture/water (14%, TZS 12,280.9B) bolsters food security (NFRA stocks at 570,519 tonnes). Concessional terms (57% multilateral) keep costs low (~1.2% interest).
• Domestic Debt (29.4%, TZS 37,459.1B): Bonds dominate (73%, TZS 27,349.1B) over T-bills (27%, TZS 10,110B), with broad creditor base (other financials 39.7%) indicating deep local markets (oversubscription in securities). This reduces FX volatility spillovers.
• Broader Implications:
  • Positive: Funds 71.9% expenditure execution (TZS 3,346.6B), enabling 6% full-year GDP projection via reliable power and exports. Shilling appreciation (+9.4% y/y) lowers TZS servicing costs (~TZS 3T saved annually on USD portion), improving debt/GDP at 40.1% (below EAC 50% threshold).
  • Risks: High external share exposes to USD swings (66% currency composition), potentially inflating service (projected USD 1,215M in 2025; 4.2% of exports). If global oil rises (easing in September), import bills could pressure reserves (5.8 months cover).

2. Sustainability and Servicing Dynamics

• Borrower and Creditor Profile: Central government's 77.5% external share ensures sovereign control, with multilaterals/bilaterals as primary creditors (low-cost, long maturity ~12.8 years). Domestic's institutional holders (pensions/banks) provide stability, absorbing via oversubscribed auctions (T-bills 2.4x).
• Fund Utilization: 82.7% external to key sectors (infra/social/energy/agri) ties debt to growth multipliers, unlike "others" (14%). This supports private credit (16.1% y/y) without crowding out.
• Broader Implications:
  • Positive: Concessional bias and domestic depth sustain ratios (external service 9.8% exports, down from 11.2% 2024). Aligns with monetary policy (CBR 5.75%), keeping real yields positive (vs. 3.4% inflation) and IBCM stable (6.45%).
  • Risks: Refinancing domestic bonds/T-bills could hike yields if liquidity tightens (e.g., from revenue shortfalls like mining taxes; 87.2% collection). Cumulative growth (+1.4% MoM total debt) demands revenue diversification beyond gold/tourism.

3. Fiscal and Macroeconomic Linkages

• Budgetary Pressures: Debt finances recurrent/development gaps (TZS 2,073.7B/1,272.9B), with servicing rising as % of spend amid delays (71.9% execution). Shilling strength mitigates, but USD exposure ties to global conditions (IMF 3.2% growth).
• Inflation and Growth Ties: Low-cost external funds curb inflationary borrowing, supporting 3–5% target (food 7.0% eased by stocks;). In Zanzibar, analogous structure aids tourism/external performance.
• Broader Implications:
  • Positive: Enhances resilience (reserves USD 6.66B), fostering M3 growth (20.8% y/y) and export surplus (USD 1.0B Q2). Positive for EAC/SADC convergence.
  • Risks: FX depreciation (reversed from 2024's -10.1%) could balloon TZS costs by 10–15%, straining deficit. Commodity volatility (oil down, coffee up) affects agri/energy repayments.

4. Policy Context from the Review

• Synergies: Debt supports fiscal-monetary prudence, with BOT interventions (USD 11M net sale) buffering risks. Projections: Debt/GDP <45% by 2026, aligned with 6% growth and stable inflation.
• Outlook: Strengthen domestic market (e.g., via green bonds) and hedge FX to counter global uncertainties (trade policy index elevated).

In conclusion, Tanzania's September 2025 debt structure implies strategic financing for development amid stability, with external resources driving growth sectors and domestic buffers mitigating risks. The 70.6% external tilt underscores FX vigilance, but concessional terms and shilling strength ensure sustainability—reinforcing the Review's narrative of prudent policies for 2026 resilience.

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.

Key Figures Illustrating Stability

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.

The Bank of Tanzania’s August 2025 review shows that Tanzania’s external debt stock stood at USD 32,955.5 million in June 2025, with the central government accounting for 85.4% (USD 28,133.7 million) and the private sector holding 14.6% (USD 4,820.6 million). By sectoral use, debt was mainly channeled into transport and telecommunications (28.6%), social welfare and education (18.5%), and energy and mining (16.7%), underscoring the focus on infrastructure and human capital development. In terms of currency composition, the debt portfolio remains highly exposed to the US dollar (69.8%), followed by the euro (18.1%), with smaller shares in the yen (5.4%) and yuan (3.2%). This structure highlights Tanzania’s reliance on public borrowing to fund long-term projects while emphasizing the importance of managing currency risk in debt servicing.

1. External Debt Stock by Borrower (June 2025)

• Total external debt stock: USD 32,955.5 million.
• Public sector dominates: Central Government accounts for 85.4%, while private sector holds 14.6%.

Details:

• Central Government: USD 28,133.7m (85.4%)
• Private Sector: USD 4,820.6m (14.6%)
• Public Corporations: USD 1.3m (≈0.0%)

2. Disbursed Outstanding Debt by Use of Funds (June 2025, % Share)

Economic Implications of External Debt Profile – June 2025

1. External Debt Stock by Borrower (June 2025)

• Composition: The total external debt stock is USD 32,955.5 million, with the central government holding USD 28,133.7 million (85.4%), the private sector USD 4,820.6 million (14.6%), and public corporations a negligible USD 1.3 million (0.0%).
• Economic Meaning: The heavy public sector dominance (85.4%) underscores the government's role in financing large-scale infrastructure and social projects, aligning with development goals (e.g., Vision 2050 targeting a USD 1 trillion economy). This reduces private sector borrowing pressure, supporting credit growth (15.9% annually), but increases public debt servicing risks (national debt at USD 46,586.6 million). The minimal public corporation share suggests limited state-owned enterprise reliance on external funds, potentially reflecting fiscal discipline. Compared to regional peers (e.g., Kenya’s 60% public share), Tanzania's high public borrowing may enhance state-led growth but requires robust revenue mobilization (tax revenue at TZS 3,108.7 billion) to sustain.

2. Disbursed Outstanding Debt by Use of Funds (June 2025, % Share)

• Allocation: Transport and telecommunications lead at 28.6%, followed by social welfare and education (18.5%), energy and mining (16.7%), agriculture (6.4%), industries (5.7%), and other sectors (24.1%).
• Economic Significance: The 47.1% allocation to transport/telecoms and social sectors supports long-term growth by improving connectivity (e.g., roads, digital infrastructure) and human capital (education, health), key to Tanzania’s 6% GDP growth projection. Energy and mining (16.7%) bolster resource exports (gold at USD 3,977.6 million), while the low agriculture (6.4%) and industries (5.7%) shares may hinder diversification, a noted challenge in IMF assessments. The "other" category (24.1%) likely includes trade and finance, indicating broad sectoral support. This mix reflects a development-focused strategy, but underinvestment in agriculture (despite 27% GDP contribution) could limit rural growth and food security (stocks at 485,930.4 tonnes).

3. Disbursed Outstanding Debt by Currency Composition (June 2025, % Share)

• Breakdown: USD dominates at 69.8%, followed by EUR (18.1%), JPY (5.4%), CNY (3.2%), and other currencies (3.5%).
• Economic Implications: The 69.8% USD exposure heightens vulnerability to exchange rate fluctuations, especially with the TZS depreciating 1.34% to 2,666.79/USD in July 2025. A stronger dollar (e.g., amid global trade tensions) could raise debt servicing costs, straining public finances (surplus TZS 403.4 billion in June). Diversification into EUR (18.1%) and JPY (5.4%) mitigates some risk, reflecting loans from multilateral institutions (e.g., IMF, World Bank). The low CNY share (3.2%) suggests limited Chinese financing compared to peers like Zambia, potentially reducing geopolitical debt dependency. Stable reserves (USD 6,194.4 million) provide a buffer, but currency risk remains a key concern.

Summary of Broader Economic Significance

• Growth and Development: The debt structure supports infrastructure and social investment, driving Tanzania’s 6% growth outlook and export resilience (USD 9,479.4 million in goods). Public sector dominance ensures state-led progress, but private sector growth (14.6%) needs nurturing to diversify the economy.
• Risk Management: High USD exposure (69.8%) and public debt concentration (85.4%) pose exchange rate and fiscal risks, though reserves and a fiscal surplus offer stability. This aligns with IMF’s moderate debt distress risk assessment, but prudent management is critical.
• Comparative Context: Compared to 2024 (USD 32.89 billion), the slight rise to USD 32,955.5 million reflects controlled borrowing, outperforming countries with higher debt-to-GDP ratios (e.g., Ghana at 90%). The sectoral focus mirrors successful models like Rwanda’s infrastructure drive, but agriculture underfunding lags behind peers.
• Future Outlook: Sustained tax revenue growth (107.8% of target) and export inflows (e.g., tourism at USD 3,871.9 million) could offset risks, though currency diversification and private sector debt expansion are needed for long-term sustainability.

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.
