When people think about investing, shares and land usually come to mind first. But one of the steadier ways to grow money in Tanzania is to lend it to the government — through Treasury bills and government bonds. They are favoured by careful investors precisely because they are among the lower-risk options available.
What bonds and T-bills are
When you buy a government bond or Treasury bill, you are lending money to the government for a set period. In return, the government pays you interest and returns your money at the end of the term. Treasury bills are short-term — months — while bonds run for longer periods, often several years, usually paying interest along the way.
Why careful investors like them
- Lower risk — government securities are considered among the safest investments in the country.
- Predictable returns — you know the interest rate and the term in advance.
- Regular income — bonds typically pay interest periodically, useful for steady cash flow.
- A stable anchor — they balance out riskier holdings like shares in a portfolio.
Lower risk does not mean no trade-offs. Your money is committed for the term, and while you can often sell a bond before maturity on the secondary market, the price you get can vary.
How to buy them
Government securities in Tanzania are issued by the Bank of Tanzania through periodic auctions, and you typically access them via a bank or a licensed broker. In general terms, you express how much you want to invest, your application goes into the auction, and if successful your securities are recorded against your details, with interest and the principal paid as scheduled.
- 1Decide how long you can commit the money — short for T-bills, longer for bonds.
- 2Go through a bank or licensed broker to take part in an auction.
- 3Invest the amount you have decided, within any minimums that apply.
- 4Receive interest as scheduled and your principal back at maturity.
Where they fit in your plan
Government securities are not about fast growth — they are about steady, reliable returns with low risk. They work well as the stable foundation of a portfolio: the calm part that keeps earning predictably while riskier investments like shares aim for higher, less certain growth. Many balanced investors hold some of each.

Frequently asked questions
What is the difference between a Treasury bill and a bond?
Treasury bills are short-term, usually maturing within a year, while government bonds run for longer periods — often several years — and typically pay interest periodically along the way. T-bills suit shorter horizons; bonds suit investors who want steady income over a longer commitment.
Are government bonds really low risk?
Government securities are considered among the safest investments in the country because they are backed by the government. The main trade-offs are that your money is committed for the term and that selling early on the secondary market can fetch a varying price — but the risk of not being repaid is very low.
