What Are Treasury Bills in Tanzania?
Tanzania Treasury bills are short-term government securities issued or administered through Bank of Tanzania. The standard market includes 35-day, 91-day, 182-day and 364-day, with investors receiving the maturity value after buying the bill at the auction or secondary-market price.
Tanzania includes a 35-day bill alongside the more common 91-, 182- and 364-day maturities. Treasury bonds extend beyond one year, so Mansa separates their yield-to-maturity observations from the short-term bill curve.
Local terminology: Treasury bills, weighted average yield, central depository and Tanzanian shilling. The official yield convention matters: discount rate, effective yield and weighted average yield are related but not interchangeable.
How to Buy Treasury Bills in Tanzania
Investors normally enter the government-securities market through the Bank of Tanzania's depository framework and an authorised bank, broker or primary dealer. The intermediary should confirm the current tender calendar, settlement requirement and maturity proceeds.
Choose a regulated channel
Use an authorised bank, dealer, broker or official depository route that can identify the security and explain its fees.
Select the maturity
Compare the available 35-day, 91-day, 182-day and 364-day bills using the same yield convention and a maturity that fits your cash needs.
Confirm price and settlement
Ask for the amount paid today, the maturity value, settlement date, charges and treatment if you need to sell before maturity.
Keep the allotment record
Retain the security reference, settlement confirmation and maturity instructions; verify that proceeds reach the nominated account.
How Treasury Bill Returns Work
Treasury bills are commonly issued at a discount: the investor pays less than the maturity value and receives the full face value when the bill matures. The cash gain is the maturity value minus the purchase amount, before fees and taxes.
An annualised auction rate is not the same as the percentage cash gain over a three- or six-month holding period. Investors should compare effective yields calculated on the same basis and confirm whether the published field is a discount rate, accepted yield or weighted average yield.

How can I buy Treasury bills in Tanzania?
Investors normally enter the government-securities market through the Bank of Tanzania's depository framework and an authorised bank, broker or primary dealer. The intermediary should confirm the current tender calendar, settlement requirement and maturity proceeds. Access rules and minimum order sizes can change, so confirm the current requirements with a regulated institution before transferring money.
Are Tanzania Treasury bills risk free?
Tanzania Treasury bills are short-term obligations of the sovereign issuer and are generally treated as lower-credit-risk local-currency instruments. They are not free of inflation, currency, liquidity, reinvestment or sovereign risk, and selling before maturity can change the realised return.
What is the difference between a Treasury bill rate and return?
A quoted bill rate is an annualised auction measure, while the investor's cash return depends on the purchase price, maturity value, holding period, fees and tax treatment. Compare instruments using the same yield convention and maturity rather than comparing headline percentages alone.
How often do Tanzania Treasury bill rates change?
Tanzania rates can change at each scheduled Bank of Tanzania auctions. Mansa Markets checks the official release pipeline and displays the underlying auction date, while this article is server-rendered on a six-hour cache window.
