Bank of Tanzania's 18 September mean was TZS 2,641.339 per US dollar, slightly below 17 September.
This reference takes the midpoint of indicative buying and selling rates. Customer rates and fees can differ; one move is not a trend.
The next finalized record will show whether the provisional 18 September mean changes.
Tanzania Railways Corporation met SYSTRA on 17 September to prepare a study for a proposed city railway.
The study would test routes, technology and costs. No committed funding amount, construction award or delivery date was disclosed.
Published study terms and financing evidence would clarify what can proceed. No construction deadline is stated.
The Ghost hypothetical model shows +17.04% since inception at its 17 September mark. The calculation adjusts for added capital; it is not a promised return.
