Analysis
How does the latest one-year bill yield compare with the shilling's year-on-year move?
What the chart shows
Official USD/TZS rose 6.95% over the exact year to 2026-09-09, while the latest 364-day bill auction yielded 6.47% on 2026-09-09. These are two independently dated observations, not a realized return comparison.
Why it matters
For overseas investors, local-currency yield and currency translation can pull in opposite directions, so the headline yield alone does not determine a translated outcome.
