The week in review
Index returns stayed unavailable as Friday liquidity remained concentrated
Signal
4,444.48 and 9,924.23 are official Friday levels, but weekly returns are unavailable; NMB carried 83.8% of Friday turnover.
Why it matters
The index basis broke during the week, and no verified 25 August row exists for a complete weekly turnover aggregate.
What to watch
An official DSE methodology notice and complete session evidence are required before weekly comparisons resume.
The visual flagship · seven linked lenses
One week. One market story. Seven ways to test it.
Start with DSEI versus TSI, then test the money, breadth, rates, currency, hypothetical model-book terrain and household transmission chain. Every lens stays frozen to this edition's stated observations.
Did the domestic market and the headline index tell the same story over the covered quarter?

02 · Turnover concentration
How much traded, and how much did one counter carry?
The week’s money had 4 very different shapes.

52.37bn shillings traded across 4 sessions, but the darker segment shows why activity and breadth are different questions.
03 · Breadth map
Did the board move with the headline?
10 advanced. 12 declined. The index hid the split.

04 · Rates hurdle
What did safe local-currency paper yield?
The short end sat below policy; the 364-day point cleared it.

2026-08-26The comparison is a hurdle-rate lens, not a ranking or recommendation. Tenor, duration, liquidity and reinvestment remain different across the instruments shown.
05 · Local vs hard currency
What remained after translating the week through USD/TZS?
A softer shilling reduced, but did not erase; the index gains.

Mechanical USD translation+4.72%
TSI
Local-currency index change+6.47%
Mechanical USD translation+6.62%
USD/TZS weakened -0.14% over the matched weekly window. The hard-currency line is (1 + local index change) ÷ (1 + FX change) − 1; it is an index translation, not an investable portfolio return, and excludes dividends, costs and tax.
06 · Ghost terrain impact
Which evidence changed the hypothetical model-book risk map?
The week changed the terrain, not the mandate.

Equities
Friday levels were official, but the weekly index return stayed unavailable across the basis break.

Auction 1205 yields fell across all four bill tenors while CBR remained 6.25%.

07 · Cost-of-living chain
How can currency pressure travel toward the household basket?
Four clocks. One transmission chain. No forecast.

Each link keeps its own authority and observation clock. The layout shows plausible transmission channels; it does not claim that one observation caused the next.
Index integrity
Official levels survived the week, but a cross-break return did not
Signal
4,444.48 and 9,924.23 are the official 28 August levels; returns across the 26 August scale discontinuity remain unavailable.
Why it matters
Keeping official levels while withholding a non-comparable return prevents a measurement break from becoming a false market move.
What to watch
What carries forward: an official DSE methodology notice or a clean comparable series before return calculations resume.
Friday liquidity
NMB carried 83.8% of Friday turnover
Signal
Friday equity turnover was TZS 10.200bn; NMB supplied TZS 8.543bn and CRDB supplied TZS 1.304bn.
Why it matters
Twenty counters traded, but the two banks supplied 96.5% of value, so the session was liquid in headline size and narrow in distribution.
What to watch
What carries forward: whether the next verified session spreads value beyond NMB and CRDB.
Comparable companies
MBP led comparable weekly gains while MCB led declines
Signal
Excluding NMB's subdivision break, 10 of 27 comparable counters rose, 11 fell and six were unchanged Friday-to-Friday.
Why it matters
The company tape stayed dispersed even though index-level weekly returns were unavailable; comparability was preserved ticker by ticker.
What to watch
What carries forward: whether the largest endpoint moves retain trading support in the next verified sessions.

Go deeper →Sovereign rates
Every Treasury bill tenor cleared below the preceding auction
Signal
Auction 1205 yields fell by 3.56 to 12.57 basis points across the 35-day, 91-day, 182-day and 364-day tenors.
Why it matters
The 364-day yield closed at 6.6492%, 39.9 basis points above the 6.25% CBR; one auction does not establish a lasting cycle.
What to watch
What carries forward: the next dated BoT bill auction tests whether the all-tenor decline persists.
FX and gold
The shilling strengthened slightly while gold ended higher
Signal
BoT USD/TZS fell 0.16% from 21 to 29 August; Mining Commission world gold rose 1.34% from 21 to 28 August.
Why it matters
Both moves were modest and source-dated; neither overrides the unresolved comparability problem in the equity indices.
What to watch
What carries forward: whether the next official FX and mineral-price observations extend either move.
Port throughput
Dar port carried a measurable operating gain into the weekend
Signal
TPA reported 30.8mn tonnes in the first 11 months of FY2025/26, above 27.7mn tonnes in all of FY2024/25.
Why it matters
The achieved volume is evidence of higher throughput, while the 33.7mn-tonne full-year figure remains a projection.
What to watch
What carries forward: final full-year tonnage, cargo mix, dwell time and rail share on their own official dates.

Go deeper →The Ghost · edition context
The model-book allocation read
The Ghost remains a hypothetical education layer at +13.35% since inception. The week changed the evidence terrain through an index-basis break, concentrated Friday liquidity and lower auction yields, not through a clean cross-asset signal.
