1. The Ranking: Africa's Weakest Currencies, June 2026
Where TZS sits, and who ranks weaker
Multiple currency trackers publishing "weakest African currencies" surveys in June 2026 — compiled using Forbes calculator data by Business Insider Africa and Tuko.co.ke — place the Tanzanian Shilling 7th weakest on the continent, requiring roughly 2,600–2,635 units per US Dollar. Six African currencies now require more than 2,000 units per dollar, led by São Tomé & Príncipe's dobra and Sierra Leone's leone.
| Rank | Country | Currency | Units per USD |
|---|---|---|---|
| 1 | São Tomé & Príncipe | Dobra (STD) | ≈ 22,282 |
| 2 | Sierra Leone | Leone (SLL) | ≈ 20,970 |
| 3 | Guinea | Guinean Franc (GNF) | ≈ 8,764 |
| 4 | Madagascar | Malagasy Ariary (MGA) | ≈ 4,176 |
| 5 | Uganda | Ugandan Shilling (UGX) | ≈ 3,651 |
| 6 | Burundi | Burundian Franc (BIF) | ≈ 2,983 |
| 7 | Tanzania | Tanzanian Shilling (TZS) | ≈ 2,600 – 2,635 |
| 8 | D.R. Congo | Congolese Franc (CDF) | ≈ 2,308 |
| 9 | Malawi | Malawian Kwacha (MWK) | ≈ 1,734 |
| 10 | Rwanda | Rwandan Franc (RWF) | ≈ 1,465 |

2. What Bank of Tanzania's Official Data Actually Shows
The IFEM rate: stable, and appreciating year-on-year
On the Interbank Foreign Exchange Market (IFEM) that the Bank of Tanzania tracks and publishes monthly, the Shilling averaged TZS 2,612.46 per US Dollar in April 2026, compared with TZS 2,684.41 per USD in April 2025 — an annual appreciation of 2.7 percent. That is an improvement on the 2.5 percent appreciation recorded in March 2026, and a sharp turnaround from the 3.9 percent depreciation recorded in the same month a year earlier (April 2025). This is the opposite direction of travel implied by a "weakest currencies" headline.

Behind this stability: gold export receipts rose to USD 5,268.9 million (year ending April 2026) from USD 3,821.2 million a year earlier — a 38 percent jump that materially eased dollar demand pressure — while tourism receipts grew 9.5 percent to USD 4,385.3 million on a 21.7 percent rise in international arrivals. The Bank's own intervention was light: it sold just USD 15.3 million on the IFEM in April 2026 "to maintain orderly market conditions" — not the scale of intervention associated with a currency under real stress.
3. Reconciling Two Different Stories
Why official and market-tracker numbers diverge
Cross-checking independent trackers as at late June 2026: Trading Economics quoted USD/TZS around 2,625 on 3 June 2026 (Shilling down 1.16% over the prior month, but still up 1.87% over the trailing 12 months — consistent with BOT's appreciation story); Wise.com recorded a June 2026 weekly range of TZS 2,596–2,634 per USD with a six-month average of TZS 2,571; and Exchange-Rates.org noted the Shilling had eased about 6.1 percent year-to-date against the Dollar by 20 June 2026 on the specific rate series it tracks.
The gap between these figures is real and worth understanding rather than dismissing. Tanzania runs a managed, not fully liberalised, exchange rate. That means:
- BOT's figure is a monthly average of the interbank rate, smoothing out day-to-day spikes that trackers like Wise or Trading Economics quote in real time.
- Different reference dates. BOT's most recent published figure is for April 2026; independent trackers quote rates through late June 2026 — two months of additional currency movement not yet captured in BOT's own release cycle.
- Retail/parallel spread. Rates used by international remittance and travel platforms often reflect a small retail markup over the pure interbank mid-rate BOT publishes.

4. Five Reasons TZS Ranks "Weak" in Nominal Terms
None of these, on their own, signal instability
No currency redenomination
Unlike Ghana (2007) or Zimbabwe, Tanzania has never redenominated the Shilling by dropping zeros. Decades of cumulative — even if moderate — inflation since the 1970s compound into a nominally large units-per-dollar figure today, independent of current-year stability.
Larger economy, larger money stock
Extended broad money (M3) reached TZS 65.1 trillion in April 2026, up 22 percent year-on-year. A bigger, faster-growing economy naturally circulates more local-currency units, which mechanically raises the units-per-dollar figure over time even without depreciation.
Nominal ranking ignores the growth rate
"Weakest currency" lists rank the level of the exchange rate, not its trend. Uganda, Burundi and several currencies ranked "less weak" than TZS by level have depreciated far faster in percentage terms over the past year than the Shilling has.
Import-dependent economy
Refined petroleum products make up about 14.4 percent of goods imports. As a net commodity importer, Tanzania's dollar demand is structurally higher than gold- and tourism-export receipts alone would otherwise imply — a genuine, if moderate, source of currency pressure.
Regional company, not global outlier
TZS sits in a cluster of East/Central African currencies (Uganda, Burundi, DR Congo, Rwanda, Malawi) that all require 1,000+ units per dollar for similar structural reasons. This is a regional pattern, not a Tanzania-specific weakness signal.
What would actually be alarming
A widening gap between the official and black-market rate, rapidly falling reserves, or double-digit annual depreciation — none of which currently apply to TZS based on the data in this review.

Within its immediate regional cluster, TZS sits between Rwanda/Malawi/DR Congo (nominally "stronger" by level) and Uganda/Burundi/Madagascar (nominally "weaker"). What distinguishes Tanzania is the combination of a diversified export base (gold, tourism, agriculture, manufactured goods) and a managed float backed by adequate reserves — a combination several of its lower-ranked regional peers lack.
6. The Real Risk to Watch: The Current Account & Global Oil Prices
Not the ranking — the trajectory
Tanzania's current account deficit widened to USD 2,651.8 million in the year ending April 2026, from USD 2,107.1 million a year earlier — a 25.6 percent deterioration — as import growth (15.5%) outpaced export growth (13.5%). This is financed comfortably today by gold and tourism inflows, but it is the genuine leading indicator for currency pressure, not the nominal exchange-rate ranking.
The transmission channel is direct: global crude oil prices jumped from USD 95.58/barrel in March 2026 to a monthly average of USD 103.91/barrel in April 2026 (intraday high USD 117.80), driven by Middle East tensions. Since refined petroleum makes up roughly 14.4 percent of Tanzania's goods imports, a sustained oil-price shock raises dollar demand mechanically — the more credible path to future TZS depreciation than the current nominal ranking implies.
The offsetting cushion
Gross official reserves stood at USD 5,722.5 million in April 2026 (up from USD 5,307.7 million a year earlier), covering 4.4 months of projected imports — within national and EAC benchmarks. Combined with record gold exports, this gives Bank of Tanzania meaningful room to defend orderly market conditions even if oil prices stay elevated through the rest of 2026.

7. Supporting Context: Inflation, Policy Rate & Credit Growth
The macro backdrop shaping currency conditions
Currency stability doesn't happen in isolation — it reflects the wider monetary and price environment. Three data points from the May 2026 BOT review matter most for the TZS story:

Why this matters for the Shilling
At its April 2026 meeting, the Monetary Policy Committee held the CBR at 5.75 percent and narrowed the policy corridor from 200 to 150 basis points to sharpen transmission — a stance consistent with defending currency stability without over-tightening credit. Inflation at 4.0 percent remains inside EAC/SADC convergence bands, meaning Tanzania is not fighting the kind of runaway domestic inflation that typically forces rapid currency depreciation elsewhere on the "weakest currencies" list (e.g., Sierra Leone, Guinea). Meanwhile, credit growth of 23.6 percent — led by trade (44.2%), mining (39.7%) and transport (39.7%) — signals an economy still expanding fast enough to keep attracting the dollar inflows that support the currency.

8. Budget, Debt & External Reserves Snapshot
The fiscal and external-debt picture underpinning currency confidence
Central government revenue continues to outperform target — TZS 3,836.8 billion collected in March 2026, 8.5 percent above target — while the national debt stock reached USD 51,067.2 million at end-April 2026, of which 70.4 percent was external debt, still dominated by concessional multilateral creditors (58.3 percent of the external stock). A well-managed debt profile and a revenue base that consistently beats target both support investor and creditor confidence in the currency's medium-term stability.

9. TICGL Analytical Take
Reading the "weakest currency" narrative correctly
- Separate the level from the trend. Investors, importers and policymakers should track the direction of the IFEM rate and reserve cover month to month — not headline rankings built purely on nominal exchange-rate level, which say little about near-term risk.
- Watch the current account, not the currency table. A 25.6 percent widening of the current account deficit in a single year is the metric most likely to translate into real TZS pressure if it persists — particularly if global oil prices stay elevated on Middle East tensions.
- Gold and tourism are doing the heavy lifting. Both sectors are cyclical and exposed to global demand and price swings. A structurally sound export base still needs diversification beyond these two pillars to keep underwriting currency stability through future shocks — a theme consistent with TICGL's broader research on Tanzania's industrialisation gap.
- Reserve adequacy remains the key buffer. At 4.4 months of import cover, Tanzania has room to absorb short-term shocks without disorderly currency moves, but this buffer would erode if the current account deficit trend continues unaddressed.
10. Frequently Asked Questions
Why does the Tanzanian Shilling rank among Africa's weakest currencies?
As of June 2026, TZS trades at roughly TZS 2,600–2,635 per US Dollar, ranking 7th weakest in Africa on a nominal units-per-dollar basis, behind São Tomé, Sierra Leone, Guinea, Madagascar, Uganda and Burundi. This reflects currency history (no redenomination) and the size of Tanzania's money stock — not an indicator of acute currency crisis.
Is the Tanzanian Shilling actually losing value?
Not on Bank of Tanzania's own official interbank (IFEM) data: TZS averaged 2,612.46 per USD in April 2026, up 2.7 percent year-on-year. Independent trackers quote day-specific rates in the 2,600–2,635 range through June 2026 and describe modest year-to-date softening — a gap explained by averaging methods, reference dates and retail spreads, not a currency collapse.
What is the difference between a "weak" currency and a "depreciating" currency?
A currency's nominal exchange rate level reflects history and structure; a depreciating currency is one losing value over time. TZS requires many units per dollar (nominal characteristic) but has been broadly stable to appreciating year-on-year on official data — unlike several African currencies experiencing double-digit annual depreciation.
What could cause the Tanzanian Shilling to weaken further?
The most plausible risk is Tanzania's widening current account deficit (USD 2,651.8 million, year ending April 2026), driven by import growth outpacing exports. A sustained rise in global oil prices linked to Middle East tensions would raise the fuel import bill and could pressure the Shilling, even as gold and tourism receipts currently offset this.
How does Tanzania defend the Shilling's exchange rate?
Through light IFEM interventions (USD 15.3 million sold in April 2026) backed by gross official reserves of USD 5,722.5 million, covering about 4.4 months of projected imports — in line with national and EAC benchmarks.
