Read: Above zero means the domestic index led. Below zero means the all-share led. A flat line near zero means their paths were similar.

Index scope differs. The measure adds only sessions with comparable published returns and is not a portfolio return. The excluded session remains disclosed in the values table.

Foreign exchange

USD/TZS stayed inside the governed BoT band

Signal

The BoT ledger records USD/TZS at 2,644.21 on the 2026-08-20 sheet.

Why it matters

The same ledger shows a -0.28% one-month shilling move and preserves the sheet date independently from the DSE close.

What to watch

Use the next BoT sheet, not an editorial lookup, to update the FX marker.

Treasury-bill curve

Auction 1204 kept the bill curve upward sloping

Signal

Weighted-average yields ran from 2.1300% at 35 days to 6.7400% at 364 days.

Why it matters

Each point is an official auction observation; the curve by itself does not establish a policy shift.

What to watch

The latest Treasury-bond result is the next dated government-securities checkpoint.
