In September 2025, Tanzania’s macroeconomic environment remained exceptionally stable, marked by a stronger shilling and low, well-anchored inflation. The exchange rate averaged TZS 2,471.69 per USD, appreciating by 0.75% month-on-month and 9.4% year-on-year—an impressive reversal from the sharp depreciation recorded in 2024. This stability was supported by strong export inflows from gold, cereals, and cashew nuts, alongside robust tourism earnings and targeted Bank of Tanzania interventions. Inflation held steady at 3.4%, well within the 3–5% target range and aligned with regional convergence criteria. Food inflation remained elevated at 7%, but non-food (1.9%) and energy inflation (3.7%) stayed subdued, helped by lower global oil prices and a strong currency. Together, these elements created a stable price environment, improving import affordability, reducing cost pressures for households and businesses, and enhancing the effectiveness of monetary policy transmission.

1. Tanzania Shilling Stability (September 2025)

The Tanzania shilling remained relatively strong and stable in 2025.

Key Figures

• Average exchange rate: TZS 2,471.69 per USD
• Previous month (August 2025): TZS 2,490.16
• Monthly appreciation: ≈ 0.75%
• Annual appreciation: 9.4%, compared to 7.6% in August 2025
  (in contrast to 10.1% depreciation in 2024)

Drivers of Shilling Strength

• Strong export inflows (gold, cereals, cashew nuts)
• Robust tourism earnings
• BOT FX market intervention (USD 11 million net sale)
• Stabilized inflation and monetary policy

2. Tanzania Inflation Evolution (2025)

Inflation remained low, stable, and within official target range.

Inflation Figures

• Headline inflation (Sep 2025): 3.4%
• Same as August 2025: 3.4%
• Target range: 3%–5%
• EAC convergence criterion: ≤ 8%
• SADC target: 3%–7%

Components

• Food inflation: 7.0%
• Non-food inflation: 1.9%
• Core inflation: 2.2%
• Energy/fuel/utilities: 3.7% (down from 11.5% in 2024 due to falling global oil prices)

3. How Shilling Stability Relates to Inflation

When the shilling is stable/strong:

1. Imported inflation falls
   • Strong shilling lowers cost of fuel, machinery, medicine, food imports.
2. Fuel prices decline
   • Domestic petrol and diesel prices dropped in 2025
     (aligned with lower global oil prices).
3. Lower cost of tradable goods
   • Stabilizes prices in urban markets (transport, household items).
4. Reduced expectations of inflation
   • Businesses experience predictable import costs.
   • Consumers face steady price trends.
5. Monetary policy becomes more effective
   • Interbank rates (6.45%) stay within policy corridor, supporting price stability.

Summary Table: Shilling Stability vs Inflation (September 2025)

Implications of Shilling Stability and Its Link to Inflation in September 2025

The interplay between the Tanzanian shilling's strength and low inflation in September 2025, as detailed in Sections 2.5 (Financial Markets, specifically the Interbank Foreign Exchange Market) and 2.2 (Inflation Developments) of the Bank of Tanzania's (BOT) Monthly Economic Review (October 2025), underscores a virtuous cycle of external resilience and price stability. The shilling appreciated 0.75% monthly (average TZS 2,471.69/USD vs. TZS 2,490.16 in August) and 9.4% annually—reversing the 10.1% depreciation seen in September 2024—amid robust export inflows (gold, cash crops, cashews), tourism earnings, and BOT's targeted intervention (net USD 11 million sale; Chart 2.5.3). This stability dovetails with headline inflation holding at 3.4% (within 3–5% target and EAC/SADC criteria), driven down by easing food (7.0%) and energy (3.7%) pressures. Below, I outline the implications, integrating broader economic dynamics like 6.3% Q2 GDP growth and accommodative policy (CBR 5.75%).

1. Shilling Appreciation: Bolstering External Buffers and Import Affordability

• Monthly/Annual Gains (0.75% and 9.4%): These reflect ample FX liquidity in the IFEM (USD 93.8 million transactions, down slightly from USD 101.5 million in August but with banks handling 88.3%), fueled by export surges in gold (elevated prices) and non-traditional items like cereals/cashews . Tourism's rebound (post-global recovery; aligned with IMF's 3.2% 2025 growth outlook) added inflows, while BOT's intervention curbed volatility without depleting reserves.
• Reversal from 2024 Depreciation: The shift from -10.1% y/y signals improved current account dynamics (e.g., trade surplus from commodities; mixed prices but oil decline aiding imports). This reduces pass-through to domestic prices, as a stronger shilling lowers USD-denominated costs (e.g., fuel imports down, mirroring global oil drop).
• Broader Implications:
  • Positive: Enhances policy space for monetary easing (interbank rate at 6.45%, within 3.75–7.75% corridor), supporting 16.1% private credit growth and 20.8% M3 expansion. Boosts investor confidence, evident in oversubscribed long-term bonds.
  • Risks: Over-reliance on gold/tourism exposes to global shocks (e.g., protectionism; Charts 1.1a/b). If exports soften (e.g., weather-hit coffee), reserves could pressure the rate, though current levels (implied adequacy) provide a buffer.

2. Inflation Stability: Reinforced by Currency Strength and Supply Factors

• Headline at 3.4% (Unchanged; Core 2.2%, Food 7.0%, Energy 3.7%): Stability stems from shilling-driven import cost relief (e.g., energy inflation halved from 11.5% y/y 2024 via cheaper oil/fuel) offsetting core upticks (household/transport). Food easing (from 7.7% in August) reflects NFRA stocks at 570,519 tonnes (up via 39,590-tonne purchases) and wholesale declines in staples (sorghum/potatoes), though rice/maize rose on regional demand.
• Non-Food at 1.9%: Highlights shilling's role in curbing imported inflation (fuel/machinery/medicine), aligning with global moderation (4.2% projected) and EAC/SADC cooling.
• Broader Implications:
  • Positive: Predictable costs foster business investment (e.g., in agriculture/mining, 1.8%/1.5% GDP contributions) and consumer confidence, aiding 6% full-year growth projection. Real rates remain positive (e.g., deposits ~6.4% real vs. 3.4% inflation), encouraging savings amid liquidity surplus.
  • Risks: Food's 7.0% (higher than headline) signals vulnerability to supply shocks (e.g., border demand or droughts). Global oil rebound could reverse energy gains, though shilling buffer mitigates.

3. Interlinkages: Shilling Strength Amplifying Monetary Effectiveness and Growth

• Reduced Imported Inflation and Expectations: Stronger shilling (9.4% y/y) directly lowers tradable goods costs (transport/utilities), stabilizing urban prices and anchoring inflation expectations—key for BOT's neutral stance. This synergy with adequate food/power supply (enabling 6.3% GDP) creates a low-volatility environment.
• Policy Transmission: Stable FX supports interbank easing (6.45% from 6.48%), with reverse repos managing liquidity, preventing spillovers to lending rates (15.18% overall; prior analysis).
• Broader Implications:
  • Positive: Aligns with fiscal prudence (August deficit financed sustainably; Section 2.6) and debt stability (total USD 50.8B, 69.8% external), enhancing external resilience (e.g., disbursements USD 443M vs. service USD 131M). In Zanzibar, similar dynamics likely aid tourism-led recovery.
  • Risks: Currency overvaluation could erode export competitiveness if sustained, though annual gains counter 2024 weakness. Monitor global uncertainties (e.g., US rate cuts weakening USD).

4. Macroeconomic and Policy Context from the Review

• Synergies Across Sections: Shilling/inflation stability complements robust output (agriculture/mining-led; Section 2.1), financial market depth (T-bill/bond oversubscription), and external debt management (multilateral dominance at 57%). Projections: Inflation 3–5%, growth 6%, with policy vigilance on commodities (oil down, gold up).
• Outlook: Continued export/tourism inflows could sustain appreciation, but diversification (e.g., manufacturing) is key. BOT's FX policy ensures balance, supporting EAC integration.

In summary, the shilling's September 2025 strength implies fortified macroeconomic stability, directly muting inflation risks and enabling growth-focused policies. This tandem—rooted in exports, interventions, and supply adequacy—positions Tanzania resiliently, though vigilance on commodity volatility and food chains is essential for 2026 continuity.

Tanzania's National Consumer Price Index (NCPI) release for September 2025, issued by the National Bureau of Statistics on October 8, 2025, reveals a stable macroeconomic environment characterized by headline inflation holding steady at 3.4% year-over-year—the highest level since June 2023 but well within the Bank of Tanzania's (BoT) target range of 3-5%. This marks no change from August 2025, with the overall NCPI edging up slightly to 119.86 (2020=100) from 119.77, driven by modest price increases in select food and non-food items. Food and non-alcoholic beverages inflation eased to 7.0% from 7.7%, reflecting a -0.6% monthly dip in the index, while non-food inflation ticked up to 1.9% from 1.6%. Core inflation, excluding volatile items like unprocessed food and energy, rose modestly to 2.2% from 2.0%, signaling underlying price pressures remain contained.

This stability, amid robust GDP growth of 5.4% in Q1 2025, underscores Tanzania's resilient post-pandemic recovery and effective policy framework.

Tanzania Inflation Overview (September 2025)

Inflation by Main Consumption Group (September 2025)

Key Monthly Drivers (Aug–Sept 2025)

Price increases were observed in:

• Food items: sorghum flour (+3.6%), bread (+1.0%), chicken (+5.0%), sweet potatoes (+7.6%), cassava (+2.2%), cocoyams (+8.9%), fruits (+2.2%), and dried peas (+4.0%).
• Non-food items: alcoholic beverages (+0.6%), men’s garments (+0.9%), kerosene (+1.1%), and charcoal (+2.7%).

Economic Implications of Tanzania's September 2025 Inflation Data

1. Monetary Policy and Macroeconomic Stability

• Support for Accommodative Stance: The unchanged headline rate and easing food pressures reinforce the BoT's decision to hold the Central Bank Rate (CBR) at 5.75% during its October 2, 2025, Monetary Policy Committee meeting. This reflects confidence in sustained inflation within the 3-5% target, avoiding the need for tightening that could stifle growth. Prudent monetary policy has historically anchored expectations, contributing to the shilling's relative stability (projected 3.7% depreciation in 2025) and low borrowing costs, which bolster private sector credit expansion.
• Risk Mitigation: Core inflation's slight uptick suggests mild demand-pull pressures from economic expansion, but the overall trajectory—fluctuating between 3.0% and 3.4% over the past year—indicates no overheating. This reduces the likelihood of imported inflation from global commodity shocks, such as energy prices, which have eased regionally.

2. Impact on Household Consumption and Poverty

• Relief for Low-Income Households: Food items, weighting 28.2% of the NCPI basket, drove much of the monthly index increase (e.g., +8.9% for cocoyams, +7.6% for sweet potatoes), yet annual food inflation's decline to 7.0% eases cost-of-living pressures for rural and urban poor households, who spend over 50% of income on food. This could sustain consumption resilience, supporting poverty reduction efforts amid 5.4% Q1 growth.
• Mixed Non-Food Pressures: The +0.3% rise in non-food inflation, fueled by essentials like kerosene (+1.1%) and charcoal (+2.7%), may strain urban budgets amid seasonal energy demands. However, stable categories like health (0.0% monthly change) and education (+0.0%) provide buffers, potentially stabilizing real disposable incomes and consumer confidence.

3. Sectoral and Supply-Side Dynamics

• Agricultural Resilience: Despite monthly spikes in crops like sorghum flour (+3.6%) and dried peas (+4.0%), the food index's -0.6% drop points to improved harvests or supply chain efficiencies, possibly from favorable 2025 rainy seasons. This bodes well for Tanzania's agriculture sector (25% of GDP), enhancing export competitiveness in East Africa and curbing imported food inflation.
• Energy and Manufacturing Pressures: Gains in the Energy, Fuel, and Utilities Index (+0.9% monthly to 3.7% annually) highlight vulnerabilities to global oil dynamics, but contained rises (e.g., liquefied hydrocarbons +0.1%) reflect BoT's forex interventions. Non-food drivers like clothing (+0.3% monthly) suggest manufacturing cost pass-throughs, potentially pressuring small enterprises but signaling domestic production gains.
• Services Sector Boost: Stable services inflation (1.3% annually) in areas like restaurants (+1.0%) and recreation (-0.1% monthly) aligns with tourism recovery, a key growth driver projected at 6% GDP expansion for 2025.

4. Broader Growth and Investment Outlook

• Pro-Growth Environment: Stable inflation complements fiscal prudence, with the IMF endorsing Tanzania's trajectory for 6% GDP growth in 2025, driven by infrastructure and mining investments. Low inflation volatility enhances investor confidence, attracting FDI (e.g., in natural gas) and supporting the shilling's stability against regional peers like Kenya's higher inflation.
• Potential Risks: Persistent food volatility (still 7.0%) could re-emerge from climate events, while global factors like OECD-projected G20 inflation moderation to 2.9% in 2026 offer tailwinds but underscore external dependencies. If non-food trends accelerate, it might prompt BoT vigilance.

In summary, September 2025's inflation data signals a "soft landing" for Tanzania's economy—stable prices fostering inclusive growth without derailing expansion. This positions the country favorably in East Africa, where peers face higher volatility, and supports the BoT's projection of inflation averaging 3.4% for the year. Policymakers should prioritize agricultural diversification and energy security to sustain this momentum into 2026.
