The Tanzania shilling (TZS) demonstrated remarkable resilience throughout 2025, appreciating by 9.5% year-on-year against the USD from October 2024 to October 2025, and sustaining firmness into December amid robust foreign exchange (FX) inflows. Key drivers included record gold exports (up 38.9% YoY to USD 2.8 billion in the first 10 months), tourism receipts (USD 2.8 billion YTD, +28% arrivals), cash crop surges (cashews +15%, tobacco +12%), and proactive Bank of Tanzania (BoT) interventions via forward sales and reserve management (net FX reserves at USD 6.2 billion, covering 4.7 months of imports). As of December 13, 2025, the shilling traded at approximately TZS 2,463 per USD, reflecting a further 0.5% monthly appreciation from November's average of TZS 2,455, per recent market data. This marks a stark reversal from the 8.9% depreciation in the prior year, aligning with EAC convergence criteria and bolstering Tanzania's external position.

Economic Implications: The shilling's strength enhances import affordability, curbing imported inflation (e.g., fuel costs down 12.5%) and supporting 3.4% headline inflation in November 2025, well within the BoT's 3-5% target. This stability fosters investor confidence, evidenced by FDI inflows of USD 1.5 billion in Q3 2025 (up 10% YoY), and facilitates lower borrowing costs (Eurobond yields at 6.8%). For the broader economy, it underpins 6.2% GDP growth projections for FY2025/26 by easing production costs in manufacturing (3.5% sector expansion) and agriculture (25.6% credit growth), while amplifying export competitiveness under AfCFTA—potentially adding USD 1 billion in intra-regional trade. However, prolonged appreciation risks eroding non-gold export margins (e.g., horticulture down 5%), highlighting needs for diversification to sustain 7% medium-term growth, per IMF's 2025 Article IV.

1.1 Exchange Rate – Month-End Values

Month-end rates show consistent firmness, with a cumulative 9.0% appreciation from October 2024 through December 2025.

Source: BoT and market data (Xe.com for Dec). Trends: The shilling peaked at TZS 2,442.8 in September 2025 amid gold surges, with minor volatility in Q4 tied to seasonal imports.

1.2 Monthly Average Exchange Rate (Oct 2025)

• TZS 2,460.54 per USD (October 2025 average), appreciating 0.5% from September's TZS 2,471.69.
• Updated December 2025 (YTD average): TZS 2,480 per USD, reflecting sustained inflows (tourism +30.6% in November).

Annual Performance:

• 9.5% appreciation (October 2024 to October 2025), extending to ~9.0% through December.
• BIG reversal from 8.9% depreciation a year earlier, driven by current account surplus narrowing to 2.4% of GDP.

Economic Implications: This appreciation reduces external vulnerabilities, stabilizing reserves (up 14% YoY) and supporting monetary easing (CBR at 5.75%). It lowers input costs for 70% import-dependent industries, boosting manufacturing productivity and contributing 0.8% to GDP via cost savings, per World Bank 2025 estimates. Yet, it pressures exporters (e.g., 5% margin squeeze in cashews), potentially slowing rural incomes (agri 24% of GDP) unless offset by value addition.

2. Tanzania Inflation Performance (2024–2025)

Inflation remained anchored within the 3-5% target throughout 2025, averaging 3.3% year-to-date through November, supported by ample food stocks (NFRA maize reserves at 593,485 tonnes in October), stable global energy prices (Brent at USD 70/barrel), and the shilling's firmness curbing pass-through effects. Headline eased to 3.4% in November 2025 from 3.5% in October, with core at 2.3% (up slightly from 2.1%), reflecting domestic supply dynamics rather than external pressures. Preliminary December data suggests stability at ~3.4%, per NBS trends.

Economic Implications: Low inflation preserves purchasing power for 60 million consumers, sustaining 3.5% private consumption growth and aligning with EAC/SADC benchmarks for regional integration. It enables BoT's accommodative stance, facilitating 16.1% private credit expansion and 6% GDP momentum. Positively, it mitigates poverty risks (26.4% rate), but food volatility (7.4% in October) underscores agri-reform needs—e.g., irrigation investments could shave 1-2pp off inflation, unlocking 0.5% additional growth via stable supplies, as noted in Deloitte's 2025 Outlook.

2.2 Food & Non-Food Inflation (Oct 2025)

Updated November 2025: Food 6.6% (down from 7.4%), non-food 2.1% (slight rise to 2.1%).

Economic Implications: Food's dominance (28.2% CPI weight) amplifies rural-urban linkages, but easing to 6.6% in November supports harvest-led recovery, adding 1% to agri GDP. Non-food stability aids urban manufacturing (e.g., cheaper inputs), but persistent food pressures risk 0.5% welfare loss for low-income households (60% budget on food).

3. Tanzania Shilling vs Inflation – Combined Table

This table illustrates the symbiotic relationship: Shilling strength offsets potential inflationary spillovers.

Source: BoT/NBS; updated with November data.

Economic Implications: The inverse dynamic (appreciating TZS vs. subdued non-food CPI) shields 40% of imports from passthrough, stabilizing energy/transport costs and contributing 0.7% to GDP via lower logistics expenses. This convergence supports fiscal space (deficit at 3.5% GDP), but food-exchange disconnect highlights supply-side vulnerabilities—addressable via USD 500M agri-investments for 1pp inflation reduction.

4. How the Shilling Affected Inflation

4.1 Stronger Shilling Helped Reduce Imported Inflation

The shilling's 9.5% appreciation in 2025 made imports 8-10% cheaper in local terms, particularly fuel (down 20%), machinery (-15%), fertilizers (-10%), and transport equipment, keeping non-food inflation at ~2.4%.

Evidence: BoT notes: “The shilling appreciated … and remained firm against other currencies,” aiding energy stability. Updated: November non-food at 2.1%, per NBS.

Economic Implications: Cheaper imports lower production costs, boosting competitiveness (exports +15.2%) and manufacturing margins (5.2% credit growth). This eases 15% of CPI (energy/utilities), supporting urban consumption and 2% GDP from services, but risks Dutch disease in non-tradables.

4.2 Inflation Remained Within Target Because of Currency Stability

Headline stayed 3-5%, meeting EAC/SADC criteria, with BoT's policy anchoring expectations.

Quote: “Inflation remained stable … supported by prudent monetary policy and stable exchange rate.”

Economic Implications: Anchored expectations reduce volatility premiums, lowering lending rates (15.19%) and enabling 21.5% M3 growth. Aligns with 6% GDP, per IMF, by fostering savings (household rate +1pp) and investment.

4.3 October 2025 Inflation Rise Was Not Due to Currency Weakness

Uptick to 3.5% from food staples (maize/rice +10-15% in pockets), not FX; November eased to 3.4% with supplies.

Economic Implications: Isolates inflation to domestic factors, allowing targeted interventions (e.g., NFRA releases), preserving FX buffers for reserves (USD 6.2B). Mitigates 0.3% growth drag from food shocks, but underscores climate resilience needs (droughts cost 1% GDP annually).

5. Key Insights

(1) The shilling appreciated strongly in 2025: Helped keep inflation low (3.4% Nov) by cheapening imports. Implication: Bolsters reserves, funding infra (1.2% GDP boost from hydropower).

(2) Inflation rose slightly due to food prices—not currency weakness: 7.4% in Oct, easing to 6.6% Nov. Implication: Highlights agri-supply focus; reforms could add 0.5% growth via stability.

(3) Non-food inflation remained low because a stronger shilling reduced import costs: Fuel/construction/pharma/transport inputs down 10-20%. Implication: Enhances industrial efficiency, supporting 16.1% credit and job creation (200K in manufacturing).

(4) Monetary and fiscal coordination supported both shilling stability and low inflation: CBR 5.75% ensured liquidity/FX. Implication: Deepens integration (AfCFTA USD 1B potential), but requires diversification to counter gold dependency (50% exports).

6. Summary Narrative

The Tanzania shilling strengthened notably in 2025, appreciating by 9.5% annually through October and holding firm at ~TZS 2,463/USD in mid-December, fueled by FX inflows from gold, tourism, and crops alongside BoT interventions. This exchange rate stability was pivotal in maintaining inflation within the 3-5% target, with headline easing to 3.4% in November from October's 3.5% peak. While food inflation (6.6% in November) drove mild pressures from domestic supplies, non-food components stayed subdued (~2.1%) thanks to cheaper imports, exemplifying a favorable exchange-rate–inflation interplay. Economically, this dynamic underpins 6%+ growth by stabilizing costs, enhancing reserves, and fostering investment, though agri-diversification remains key to long-term resilience amid global uncertainties.
