USD/TZS changed 6.9% YoY to 3 Sep 2026; the 364-day bill yielded 6.65% (26 Aug 2026)
Official USD/TZS rose 6.87% over the exact year to 2026-09-03, while the recorded 364-day bill auction yielded 6.65% on 2026-08-26. These are two independently dated observations, not a realized return comparison.
The comparison places the exact-year change in the official BoT indicative USD/TZS mean beside the annualized weighted-average yield from the latest 364-day bill auction. It does not align holding periods or include reinvestment, tax, costs, price changes or execution rates.
