- 01Banks fell while industrial shares gained
- 02One weekly decline, different sector paths
- 03Two banks accounted for almost nine shillings in ten
The week in review: 12 to 16 October
Banks fell while industrial shares gained
Signal
The main share-price measures fell this week, but industrial shares rose. The decline was not shared by every sector.
Why it matters
The All-Share index fell 0.54% and the domestic index 0.62% from 9 to 16 October. Banks and industrials moved in opposite directions.
What to watch
Different company weights can explain a falling index despite sector gains. Friday close: DSEI 4,572.74, TSI 10,079.13.

Revision 1: verified weekly analysis supplements the preserved original edition. The original four-session source window and reference-close basis are retained.
02 · Turnover concentration
How much traded, and how much did one counter carry?
TZS 12.94bn · TZS 12,943,737,790 · four verified sessions; 14 October was a market holiday. Activity and breadth measure different things.
03 · Weekly reference-close breadth
▲10 up▼13 down=5 unchanged
All 28 comparable 9 and 16 October reference closes, including non-traded reference prices. This is weekly price breadth, not Friday traded-counter breadth.
04 · Rates comparison
Carried 7 October auction 1208, not a new weekly result. Annualized yields, not weekly returns.
Policy is context. Maturity, duration, liquidity, reinvestment, costs and tax differ; this is not a ranking or recommendation. Prior 23 September 364-day yield:6.2852%.
05 · Local vs hard currency
The indices fell; USD translation enlarged the losses.

Local-currency index change: −0.54%
Mechanical USD translation: −0.60%

Finalized BoT means: 2026-10-09 · 2631.3587 → 2026-10-16 · 2633.1199 TZS/USD; +0.07%.
(1 + local index change) ÷ (1 + FX change) − 1. Matched 9 to16 October endpoints; no provisional Sunday fallback. Excludes dividends, costs and tax; an index translation, not an investable portfolio return.
Additional Ghost commentary is pending source and bilingual editorial review and is excluded from this corrected edition. Verified market analysis and the covered period are retained.
The EN/SW session mover lists both rank only 16 October counters with positive reported volume and turnover, using 15→16 verified closes. Three rises and three falls; not the full board. NMG reference close310→305 (−1.61%) had zero volume and turnover, so is excluded from traded movers, not erased from reference-price history.
Share prices
One weekly decline, different sector paths
Signal
Bank shares fell this week while industrial shares rose. A falling market measure did not mean every sector weakened.
Why it matters
From 9 to 16 October, banks fell 1.62% and industrials rose 1.74%. The domestic index, which combines company prices, fell 0.62%.
What to watch
Companies have unequal weights in an index. That can explain the split; these changes alone do not reveal its cause.
Friday trading
Two banks accounted for almost nine shillings in ten
Signal
Almost nine of every ten shillings traded on Friday went through two banks. This does not describe the full week.
Why it matters
CRDB and NMB accounted for 89.6% of Friday’s TZS 3.652bn share trading. A 400,000-share CRDB block was part of the session.
What to watch
A block is a pre-arranged trade. This total includes it; concentration cannot establish investor confidence or trading motives.
Currency
The dollar reference reversed its previous weekly decline
Signal
The official dollar reference rose slightly over the week. A dollar required more shillings than on the previous Friday.
Why it matters
The finalized mean rose from TZS 2,631.3587 on 9 October to 2,633.1199 on 16 October. It is a reference, not a customer quote.
What to watch
A share-price result in shillings differs from one converted to dollars. The exchange date, customer price and fees affect conversion.
Government borrowing
The bill-auction record did not advance this week
Signal
The latest verified bill-auction rates still come from 7 October. They are background for this week, not a new rate change.
Why it matters
The 364-day yield is 6.2839%; the 91-day yield is 3.4908%. Yield is the annualised return implied by the auction price.
What to watch
The next published auction will test whether rates changed. These auction results are not customer returns after fees or tax.
Opportunity Wire
A drainage contract defines work, but not its cash timetable
Signal
The roads agency, TANROADS, reported a drainage contract on Thursday. Its funding source and payment timetable remain undisclosed.
Why it matters
Boko-Basihaya’s TZS 59.49bn contract names China Gezhouba Group and 14 months. This is the work’s value, not money already paid.
What to watch
A confirmed start date and payment terms would clarify delivery. Better road access depends on construction and drainage performance.

The model-book allocation read
The hypothetical Ghost model book recorded +17.58% since inception at the 16 October mark. Modified Dietz accounts for contribution timing; it is not a live portfolio or a weekly index return.
Open the current Ghost tracker →What this edition watched
Next official DSE close
Tests whether the bank and industrial paths remain different; a price change alone cannot explain the cause.
Next verified session; publication time unconfirmed
Next finalized currency observation
Shows whether the small rise in shillings per dollar persists. Customer conversion prices and fees remain separate.
Next dated Bank of Tanzania release; time unconfirmed
Next Treasury-bill auction result
Would replace the 7 October borrowing-rate reference with a new dated result.
No next date verified in the frozen auction record
Boko-Basihaya drainage construction and payments
Would connect the signed contract to actual work and payments; the 14-month period has no verified start here.
Start date and payment schedule not disclosed
Information and education, not advice or a solicitation. Week: 12 to 16 October 2026, with four verified sessions and the 14 October market holiday. DSE frozen to the verified 16 October close; weekly index changes compare 9 and 16 October. An index combines company prices with unequal weights. DSEI covers all shares; TSI covers domestic companies. Prose changes are rounded to two decimals; chart changes retain four. Turnover means the value of shares traded. Friday turnover, its 89.6% two-bank share and the movers are session-only, not weekly totals. Revision 1: verified turnover for the four sessions is TZS 12,943,737,790 (12.94bn). Across 28 comparable 9 and 16 October reference closes, 10 rose, 13 fell and 5 were unchanged; this weekly reference-close breadth is distinct from Friday traded-counter breadth. BoT currency endpoints: finalized 9 and 16 October means; strip: provisional 17 October sheet. Bill-auction rates: 7 October, compared with 23 September; no new bill result in the verified record. TANROADS publication: 15 October; contract signing and construction-start dates are not separately established. The 14-month period is not a calendar completion date. Sources describe different markets and periods and do not establish a common cause. Terms: /learn/glossary. Live updates: Markets. TZS means Tanzanian shillings; bn means billion.
