SECTION 01
TZS/USD Exchange Rate & Headline Inflation — Dual-Axis Overview (2018–2026)
The signature chart of this analysis: TZS/USD annual average (left axis) plotted against annual headline inflation (right axis). The relationship is not always direct — Tanzania's inflation has multiple drivers — but every major depreciation episode leaves a visible imprint on the price level with a 6–12 month lag.
TZS/USD Exchange Rate vs Tanzania Headline Inflation (%)
Annual averages 2018–2025 + monthly data Jan–Apr 2026. Left axis: TZS per USD. Right axis: Annual inflation rate (%).
Reading the chart: Notice that the 2023–2024 sharp depreciation (TZS 2,382 → 2,597) did not immediately spike headline inflation — because food inflation was subdued and the CBR was held firm. The April 2026 inflation jump to 4.0% is instead driven by global oil prices (+65.6%), not a weaker shilling. In fact, the shilling appreciated 2.7% year-on-year in April 2026.
TZS/USD Annual Average — 8-Year Trend
Depreciation story: TZS weakened from 2,264 (2018) to a peak of 2,597 (2024) — a cumulative 14.7% depreciation over 6 years. The 2025 average recovered slightly to 2,538, and April 2026 traded at 2,612.
Annual Headline Inflation — 8-Year Trend (%)
Contained inflation: Despite significant exchange rate movements, Tanzania's headline inflation has stayed in a narrow 3.1–4.3% band over 2018–2026, well within EAC and SADC targets. This demonstrates effective monetary anchoring by the Bank of Tanzania.
SECTION 02
TZS Depreciation vs Inflation — Correlation & Quantified Impact
How tightly does the shilling's movement translate into price changes? The correlation is positive but moderate — depreciation raises import costs and fuel prices, but Tanzania's large domestic food production and BOT's active monetary management buffer the full pass-through.
TZS Annual Change (%) vs Inflation Change (pp) — Year-on-Year
Key finding: Years of significant TZS depreciation (2023–2024) coincided with declining or flat inflation, because food prices (the largest CPI basket component at 28.2%) were falling. This shows the currency-inflation link in Tanzania is mediated primarily through energy/fuel imports, not food.
Annual TZS Depreciation (+) / Appreciation (−) vs Inflation (%)
2024 anomaly: The shilling depreciated 8.2% in 2024 (steepest in the series), yet headline inflation fell to 3.1% from 3.8%. Food deflation, declining oil prices, and strong forex reserves allowed BOT to prevent pass-through — a testament to effective policy.

SECTION 03
Phase-by-Phase: TZS & Inflation History (2018–2026)
Tanzania's exchange rate and inflation history can be divided into four distinct phases, each with a different dominant driver and policy response.
TZS/USD Monthly Rate — Trend Line 2018–2026
2018–2021
Phase 1: Remarkable Stability
TZS held between 2,264 and 2,298/USD for four consecutive years — one of SSA's most stable exchange rate periods. BOT maintained tight liquidity. Inflation averaged 3.5% driven by domestic food and services.
2022
Phase 2: Global Commodity Shock
Russia-Ukraine war spiked global commodity prices. Fuel imports surged. Inflation peaked at 4.3% — the cycle high. TZS held steady at 2,303/USD due to strong gold export earnings and BOT FX intervention.
2023–2024
Phase 3: Sharp Depreciation, Surprising Disinflation
TZS weakened 8.2% in 2024 alone (2,382→2,597/USD). Counterintuitively, inflation fell to 3.1%. Declining global commodity prices, a bumper harvest season, and NFRA food stock releases offset the FX pass-through. BOT maintained CBR at 5.5%.
2025–2026
Phase 4: Shilling Recovery, New Inflation Driver
TZS appreciated 2.7% YoY in April 2026 (2,684→2,612/USD), supported by gold export boom (+42% revenue) and BOT FX sales. But inflation jumped to 4.0% in April 2026 due to Middle East geopolitical conflict driving crude oil to USD 104/barrel — a global, not local, shock.
SECTION 04
Inflation Decomposition — What Actually Drives Prices in Tanzania?
Breaking inflation into its components reveals that the TZS/food price link dominates in years of shilling weakness, while energy/fuel inflation is the direct transmission channel from global oil prices. Core inflation — which excludes food and energy — tracks domestic demand and is the most policy-relevant measure.
Inflation Components — Annual Rates by Year 2018–April 2026 (%)
Food Inflation vs TZS/USD (2024–Apr 2026)
Food inflation peaked at 7.7% in August 2025, well after the 2024 TZS depreciation — consistent with 6–12 month lag. By April 2026 food inflation had moderated to 5.7% as harvest season approaches.
Energy/Fuel Inflation vs Oil Price (2025–Apr 2026)
Energy inflation surged from 2.1% (March 2026) to 5.3% (April 2026) in a single month, directly tracking the crude oil price jump from USD 95.58 to USD 103.91/barrel. This is the sharpest single-month energy inflation increase in the dataset.
Core Inflation — Domestic Demand Signal (%)
Core inflation held between 1.9–2.7% through all of 2025, signalling well-anchored domestic demand. The April 2026 jump to 3.1% is driven by transport (fuel pass-through into services), not structural price pressures.
Contribution to Overall Inflation (Percentage Points) — Apr 2025 to Apr 2026
Reading the stacked bars: Core inflation (blue) has been the largest single contributor throughout the period. The April 2026 spike is explained by energy/fuel and core both rising simultaneously — the first time both have elevated together since 2022.
SECTION 05
Month-by-Month: TZS Rate & All Inflation Measures (Jan 2025 – Apr 2026)
The highest-resolution view of the TZS-inflation relationship: 16 months of monthly data showing the TZS/USD rate alongside headline, food, core, and energy inflation simultaneously. This granular view reveals how quickly global oil prices transmitted into domestic prices in March–April 2026.
Monthly TZS/USD Rate (left axis) vs Inflation Measures (right axis) — Jan 2025 to Apr 2026
Month-on-Month CPI Change (%) — Jan 2025 to Apr 2026
The 1.3% month-on-month increase in April 2026 is the largest single monthly CPI jump in the 2025–2026 series, driven by transport (+5.2% MoM) and food (+0.9% MoM). In contrast, most months in 2025 recorded MoM changes of 0.1–0.9%.
TZS/USD End-of-Period Rate — Monthly (2025–2026)
The shilling strengthened from TZS 2,684/USD (April 2025) to TZS 2,602/USD (June 2025), then gradually weakened to TZS 2,612/USD (April 2026). The +2.7% year-on-year appreciation has provided a modest but meaningful anti-inflationary buffer.
SECTION 06
How TZS Movements Transmit to Consumer Prices — The Four Channels
Exchange rate depreciation does not raise all prices equally. Understanding the specific transmission channels is critical for interpreting TZS movements and their likely inflation impact in Tanzania's context.
Fuel & Energy Channel — FAST & DIRECT
Tanzania imports ~100% of refined petroleum. A weaker TZS directly raises pump prices within 1–2 months. Energy/fuel CPI has the highest correlation with TZS movements. Government fuel subsidies dampen but don't eliminate this channel.
Lag: 1–2 months
Imported Food Channel — MODERATE & SELECTIVE
Tanzania produces ~75% of its food domestically, so the food-currency link is weaker than in more import-dependent economies. Key imported items: wheat, cooking oil, sugar. Domestic food prices respond more to rainfall and NFRA stock releases than to TZS movements.
Lag: 3–6 months
Industrial Input Channel — SLOW & DIFFUSE
Manufacturing inputs (fertilisers, chemicals, machinery parts) priced in USD filter into local production costs over 6–12 months. This channel explains the stickiness of core inflation during and after depreciation episodes. Credit expansion amplifies this channel.
Lag: 6–12 months
Transport & Logistics Channel — FAST & BROAD
Transport costs (14.1% CPI weight) respond immediately to fuel price changes. Because transport is an input into every other sector, fuel-driven transport inflation cascades across food, health, education and services categories within 1–3 months of a fuel price change.
Lag: 1–3 months
Transport Inflation vs Fuel Prices vs TZS/USD — Monthly (2025–Apr 2026)
April 2026 case study: Crude oil rose from USD 65.91/barrel (April 2025) to USD 103.91/barrel (April 2026). Domestic diesel prices rose. Transport inflation hit 9.2% annual — and with transport as an input cost for 80%+ of consumer goods, this diffuses broadly across the CPI basket. The shilling's 2.7% appreciation partially offset the oil shock but could not fully absorb a 65% oil price increase.

SECTION 08
Outlook: TZS Stability & Inflation Trajectory — What to Watch
The critical question for the remainder of 2026: can the shilling hold its ground while global oil prices remain elevated, and will the May–June harvest season provide the food disinflation needed to bring headline inflation back toward 3.5%?
✔ Factors Supporting TZS Stability & Lower Inflation
- → Gold export boom: USD 5.44 billion in the year to April 2026 (+42.3%) sustains foreign reserve accumulation and underpins TZS demand
- → Harvest season (May–June 2026): BOT explicitly flagged this as the key food disinflation catalyst — food inflation expected to moderate from 5.7%
- → NFRA food stocks: 500,962 tonnes held as of April 2026 — government can release to stabilise prices
- → Forex reserves: USD 5.72 billion (4.4 months of imports) provide BOT with ample ammunition for FX intervention
- → Government fuel subsidies: Partially absorbing the global oil price shock — limiting pass-through to pump prices
- → Tourism revenue: Tanzania-mainland + Zanzibar combined travel receipts growing strongly, supporting USD inflows
⚠ Risks to TZS Stability & Inflation Outlook
- → Middle East escalation: Further geopolitical tensions could push crude oil above USD 120/barrel — BOT projects near-term inflation risk remains elevated
- → USD debt servicing: USD 242 million in external debt service in April 2026 alone creates structural USD demand pressure on the shilling
- → Import growth outpacing exports: Trade deficit widened to USD 5.35 billion (2026p) — sustained import demand absorbs USD and pressures the shilling
- → Global inflation revised up to 4.4%: External price levels feeding into Tanzania's import prices regardless of TZS strength
- → Fertiliser prices rising: DAP prices at USD 725/tonne (March 2026), up from USD 320/tonne (April 2024) — threatening food production costs for the next growing season
- → Core inflation now rising: Jump from 2.2% to 3.1% in one month (Mar→Apr 2026) signals that oil-driven transport costs are beginning to seep into underlying prices
Key Indicators at a Glance — Tanzania Shilling & Inflation Dashboard (April 2026)
Bottom line for investors and policymakers: The Tanzanian shilling is in better shape than it was in 2024. The April 2026 inflation spike is an external supply shock (oil), not a TZS weakness problem. If Middle East tensions ease and the harvest season delivers, headline inflation should moderate toward 3.5% by Q3 2026. The critical monitor: crude oil prices and TZS/USD monthly average.
