Treasury bills are short-term government securities issued by the Bank of Zambia on behalf of the Zambian Government. They allow the state to borrow money for a limited period, while investors earn a return when the bill reaches maturity. For a cautious beginner, they can be easier to understand than shares, property, or complex investment products.
Buying a Treasury bill does not mean placing money in an ordinary savings account. The investment has a fixed maturity date, the return is usually built into the purchase price, and access to the money before maturity may depend on finding a buyer in the secondary market. Understanding these details helps you choose a suitable term and avoid committing money needed for daily expenses.
This guide explains how Treasury bills work in Zambia, where to buy them, how returns are calculated, and which risks deserve attention. It is general information for education, not personal investment, tax, or financial advice. Readers who follow practical local topics can also explore the wider Zambian money guides available on Je-Phiri.
A Treasury bill is a short-term debt instrument. You lend money to the government by buying the bill at a price below its face value. At maturity, the government pays the full face value. The difference between what you paid and what you receive represents your gross return before any applicable charges or taxes.
For example, a bill with a face value of K10,000 might be purchased for less than K10,000. If you hold it until the maturity date, you receive K10,000, subject to the terms of the issue. The exact price is determined through the auction process, so the return is not always known until bids are allocated.
The Bank of Zambia issues Treasury bills through government securities auctions. Common maturities have included 91, 182, 273, and 364 days, although available tenors and auction arrangements can change. A longer maturity may offer a different yield, but it also keeps your money committed for a longer period.
Treasury bills differ from Treasury bonds. Bills are short-term instruments, generally maturing within one year, while bonds normally have longer maturities and may pay periodic interest. Both are government securities, but their cash-flow patterns and price movements are different.
The main attraction is relative simplicity. You can select a maturity, invest through an approved channel, and wait for the bill to mature. The return is linked to the government’s borrowing cost rather than the daily performance of a company or a fund. This makes Treasury bills useful for people who want to preserve capital while earning something on money that would otherwise remain idle.
They can also support short-term financial planning. Someone saving for school fees, a business purchase, or a planned payment may choose a maturity that broadly matches the date when the money will be needed. The investment should still be separated from an emergency fund because unexpected expenses may arise before maturity.
The return is usually more predictable than the return from shares, but “government-backed” does not mean risk-free in every practical sense. The government must honour its obligations, and payment timing, auction conditions, inflation, taxes, and access to the secondary market can affect the investor’s experience.
Inflation is especially important. If prices rise faster than the Treasury bill’s effective return, the purchasing power of your money may decline even when the investment produces a positive nominal gain. Compare the likely return with your purpose for investing, rather than focusing only on the percentage rate.
A beginner normally starts by contacting a commercial bank, investment bank, or licensed securities dealer that participates in the government securities market. Ask whether the institution accepts individual investors, what minimum amount applies, which documents are required, and whether it will help open or link the necessary Central Securities Depository account.
The investor may need a National Registration Card or passport, a Taxpayer Identification Number, proof of address, a bank account, and completed customer due diligence forms. Requirements vary between institutions. Use the institution’s official channels and confirm all payment instructions before transferring funds.
There are usually two broad ways of participating in an auction. A competitive bid specifies the price or yield at which you want to invest, while a non-competitive bid accepts the auction’s determined rate, subject to the applicable rules. Beginners may find non-competitive participation easier, but they should ask the intermediary how each option works and whether either has different allocation conditions.
Your bank or broker should explain the auction date, settlement date, maturity date, fees, minimum investment, and expected amount at maturity. Keep the trade confirmation and statements. After settlement, check that the security appears correctly in your account records and that the maturity instructions are understood.
Do not send money to an individual promising a guaranteed Treasury bill allocation through social media. Genuine providers should be identifiable, regulated where applicable, and able to issue formal documentation. If an offer demands an unusual “release fee” or promises returns far above normal government securities, treat it as a warning sign.
Treasury bills occupy a middle ground between keeping cash in a bank account and investing in assets whose value can move sharply. A savings account is generally easier to access, but its interest rate may be lower or variable. A fixed deposit can also lock money for a set period, with terms determined by the bank.
Money market funds invest in short-term instruments and may offer convenient withdrawals, but they have management fees, fund rules, and investment risks. Shares can provide long-term growth and dividend income, yet their market prices may rise or fall substantially. A Treasury bill is usually selected for a defined short-term goal rather than indefinite wealth accumulation.
The most suitable option depends on liquidity, risk tolerance, time horizon, and the purpose of the money. The following comparison gives a general guide; actual rates, fees, access rules, and product terms should be confirmed with an authorised provider.
| Option | Typical access to money | Return pattern | Main risks or limitations |
|---|---|---|---|
| Treasury bills | Usually at maturity; early sale may require a secondary-market transaction | Discount-based return determined by price and maturity | Inflation, rate changes, limited early liquidity, sovereign repayment risk |
| Savings account | Generally easy access | Variable interest, often credited periodically | Low returns, fees, and loss of purchasing power |
| Fixed deposit | Restricted until the agreed term ends or subject to penalties | Agreed bank interest rate | Early withdrawal penalties and changing deposit rates |
| Money market fund | Often available according to fund rules | Income from a portfolio of short-term assets | Fees, fund performance, and redemption timing |
| Shares | Usually sellable during market hours if there is a buyer | Potential capital gains and dividends | Price volatility, company risk, and possible losses |
A useful way to compare products is to calculate the amount you will actually receive, not just the advertised rate. Include transaction costs, taxes where applicable, and the effect of investing for a different number of days. Ask whether a quoted yield is annualised and whether it is calculated on the purchase price or face value.
Treasury bill returns are commonly expressed as a discount yield or annualised yield. The quoted rate may not be the same as the simple percentage difference between the purchase price and face value. Your provider should show the purchase price, face value, maturity date, fees, and expected proceeds in writing.
A simplified illustration can make the process clearer. Suppose a K10,000 face-value bill is bought for K9,600 and held to maturity. The gross difference is K400. That is a 4.17% return on the K9,600 invested over the bill’s term, but the annualised equivalent would depend on the exact number of days. This example is for explanation only and is not a current Zambian auction rate.
You should ask about brokerage or dealing fees, custody charges, account-opening costs, and any bank transfer charges. Tax treatment can depend on the investor’s status and current Zambian rules. Confirm whether withholding tax applies, whether the quoted amount is gross or net, and how the transaction will appear in your records.
Reinvestment is another issue. When a bill matures, you may need to place the proceeds into a new auction if you want to continue investing. Future yields may be higher or lower. A laddering strategy—dividing money across several maturity dates—can reduce the risk of having everything mature at one time and may provide more regular access to funds.
The first risk is liquidity. Treasury bills are designed to be held until maturity, and selling early may not be as straightforward as withdrawing from a bank account. A buyer may not be immediately available, and the market price can be below the amount you originally paid. Do not invest money needed for rent, food, medical care, debt payments, or imminent school costs.
Interest-rate risk matters when you sell before maturity. If new Treasury bills begin offering higher yields, an existing bill may become less attractive and could need to be sold at a lower price. If you hold the bill to maturity, daily price changes are generally less relevant, provided the issuer meets its obligation.
Credit or sovereign risk should also be acknowledged. Treasury bills are issued by the government, but government finances can face pressure. Zambia has experienced debt-related economic difficulties in recent years, so investors should review official announcements and understand that a government security is not identical to a deposit protected by a bank deposit insurance arrangement.
Inflation, currency movements, and concentration create further risks. A return in kwacha may lose value against imported goods or foreign currency, and putting all savings into one maturity or one asset leaves little flexibility. Diversification does not remove risk, but it can prevent one investment decision from controlling your entire financial position.
Before investing, use these practical checks:
Start with an amount that allows you to learn without putting essential finances under pressure. Read the latest Bank of Zambia auction notices and ask your provider to explain the current maturities, bidding process, and settlement timetable. Do not choose a term solely because it has the highest quoted rate; the longest term may be unsuitable if you need access sooner.
A basic ladder might divide available investment money between 91-day, 182-day, and 364-day bills. As each holding matures, you can use the proceeds, reinvest them, or adjust the allocation. This approach can provide a balance between earning a return and maintaining periodic access to cash.
Keep a record of the purchase price, face value, yield, maturity date, fees, tax documents, and the purpose of the investment. Review the plan when your income, debts, family responsibilities, or business needs change. Treasury bills work best as part of a wider financial plan that may include cash savings, insurance, pension contributions, and carefully selected long-term investments.
Financial decisions often compete with other priorities, including education and household spending. For readers comparing local education options alongside personal budgeting, this UNZA and CBU comparison offers a reminder that major financial commitments should be assessed by total cost, timing, and long-term value rather than by one headline figure.
Use the guidance above as a starting point, then obtain current terms directly from the Bank of Zambia or a licensed intermediary before placing funds. Compare the written offer, understand when your money will be available, and invest only an amount that fits your own cash-flow plan.
