The 1.19% real return: Is investing ₦100,000 in Nigerian Treasury bills still worth it?

This is Follow the Money, our weekly series that unpacks the earnings, business, and scaling strategies of African fintechs, financial institutions, companies, and governments. A new edition drops every Monday.

Leaving ₦100,000 ($75.5) idle in a commercial bank account might feel safe, but with inflation eroding the purchasing power of cash, more Nigerians are seeking higher-yielding alternatives.

Treasury bills (T-bills) have emerged as one of the most accessible vehicles for retail capital.

These short-term debt securities are issued by the Federal Government of Nigeria and mature in a year or less. Sold via periodic central bank auctions, primary dealers bid on price and yield. Essentially, investors lend funds to the government for a fixed duration and receive their principal plus built-in returns at maturity.

Institutional interest in the asset class remains formidable. At the recent September 9 auction, total investor demand reached ₦2.64 trillion ($1.99 billion). The Debt Management Office (DMO) ultimately allotted ₦1.05 trillion ($792.8 million)—more than double its initial planned offer—with 364-day bills accounting for 91% of total subscription volume.

For a retail investor, however, the relevant question is simpler: what actually happens when you commit ₦100,000 ($75.5)?

The access chain: where your money goes

A retail investor cannot walk into the Central Bank of Nigeria (CBN) with ₦100,000 ($75.5) and bid directly for an auction.

While the Debt Management Office (DMO) manages the federal domestic borrowing programme, the Central Bank of Nigeria (CBN) conducts the primary auctions on the government’s behalf.

Direct access is restricted to primary dealers—licenced commercial banks and discount houses. Wealthtech platforms, asset managers, and stockbrokers aggregate retail capital and place consolidated orders through these primary dealers.

At auction, dealers submit bids detailing their required volume and stop rate. The clearing rate is not set in isolation; it competes against alternative money market instruments, commercial paper yields, interbank placement rates, and the CBN’s Monetary Policy Rate (MPR). If competing instruments offer higher yields, the government must adjust its rates upward to attract sufficient borrowing.

Once a bid is accepted, the underlying security is held electronically by a licensed custodian on the investor’s behalf. The government secures short-term funding, the primary dealer executes the order, the asset manager earns a structuring fee or spread, and the retail investor receives a digital credit in their investment account.

If those alternatives offer attractive returns, investors have less reason to accept a low T-bill rate. The government therefore has to offer a return that attracts enough demand to meet its borrowing needs.

The CBN’s monetary policy rate (MPR) also influences the broader interest rate environment. When rates across the financial system are high, T-bills have to compete with other naira investments for investors’ money.

Once a bid is accepted, the investor owns a government security. A custodian holds the security on the investor’s behalf, and it appears in the investment platform or account through which it was purchased.

The government gets funding. The dealer gets an order to execute. The asset manager or investment platform gets a customer and, depending on its business model, earns fees for arranging or managing the investment. The custodian holds the underlying security.

Your ₦100,000 ($75.5) has moved through a financial system before it becomes a T-bill.

The market behind your investment

The auction determines which bids get accepted. Investors indicate the rates at which they are willing to buy, and the auction establishes a cut-off, known as the stop rate.

Demand has been particularly strong for longer-dated bills. At the latest auction, investors wanted ₦2.54 trillion ($1.92 billion) of the 364-day bills on offer, far more than the amount allotted.

Yet, the rate has been falling. The 364-day stop rate was 17.59% on August 12, 17.15% on August 26, 16.84% on September 2, and 16.62% on September 9. That is a 97-basis-point decline in four weeks.

It tells you something about the market. Investors still want government debt, but they are accepting lower returns to get it.

The government also wants more of that money. Its third-quarter Treasury bill programme plans to raise ₦5.8 trillion ($4.4 billion), including ₦4 trillion ($3.02 billion) through 364-day bills. The shorter 91-day and 182-day bills account for ₦900 billion ($679.5 million) each.

For the government, T-bills are a way to raise short-term funding. For investors, they offer a relatively low-risk security to put cash while earning a return. Banks, dealers, asset managers, and investment platforms sit between both sides of that transaction.

A platform that buys T-bills for customers has to manage the difference between the price it gets in the market and the return it offers the customer. Depending on the structure, it can also charge fees for managing or processing the investment.

A small difference can become meaningful at scale. If a dealer acquires a T-bill at a better rate than the one offered to its retail customers, the spread between those two rates can become revenue. A platform serving thousands of customers does not need a large margin on each transaction for the numbers to add up.

But the margin is not necessarily the same across platforms, and not every wealth-tech company makes money from T-bills in the same way. Some may earn through fees, while others may make money from the spread between the rate at which they acquire the bills and the rate they offer retail investors, or use T-bills as part of a broader investment product.

What ₦100,000 can buy

T-bills are sold at a discount. You pay less than the bill’s face value and receive the full face value when it matures.

At the September 9 auction, the 364-day bill had a 16.62% stop rate. Investors had submitted bids ranging from 15.59% to 19.23%, but the government accepted bids between 15.59% and 16.62%. The pattern was similar across the other tenors. The 91-day bill attracted bids as high as 20%, but stopped at 16.3%, while the 182-day bill stopped at 16.5% after bids reached 17.6%.

The gap between what investors asked for and where the auction eventually cleared shows that the government did not have to pay the highest yields investors were demanding. It also gives a clearer picture of the market’s pricing: investors were willing to ask for double-digit returns, but the auction ultimately set a lower clearing rate across all three tenors.

Using the 364-day rate as an illustration, ₦100,000 invested at the auction would buy roughly ₦119,900 worth of face value. If held until maturity, the investor would receive that face value, giving a gross gain of about ₦19,900 before any applicable fees, charges, or taxes.

A person with ₦100,000 ($75.5) to invest could therefore buy more than ₦100,000 ($75.5) worth of face value at that rate, assuming the investment is available on those terms. The exact return depends on the auction rate, the maturity period, and how the investment is accessed.

The exact amount an individual receives can differ depending on the price at which they buy, the platform they use, and whether they buy at the primary auction or later in the secondary market.

The important part is how the investment works. You are not putting ₦100,000 ($75.5) into a savings account that pays interest every month. You are buying a government security below its maturity value and earning the difference when it matures.

The government, meanwhile, has borrowed your money for the life of the bill.

What happens if you need the money early?

The relative safety of sovereign paper is the primary reason investors accept yields that sit below those offered by riskier corporate instruments.

Corporate borrowers must offer a credit-risk premium to compensate investors for default risk; Nigerian government securities, by contrast, carry a sovereign guarantee backed by the full faith and credit of the federal government.

Yet sovereign backing does not automatically guarantee an attractive real return. While a ₦100,000 investment generating a ₦19,900 gain leaves the investor with more nominal naira at maturity, the critical metric is purchasing power.

Inflation remains the decisive factor: if headline consumer prices rise faster than the investment yield, nominal gains mask a net loss in real wealth.

With Nigeria’s headline inflation recorded at 15.43% in July, the latest T-bill stop rate of 16.62% sits only marginally above the annual surge in consumer prices. Should inflation remain elevated at these levels, the security delivers a paper-thin real yield of roughly 1.19% before platform fees and transaction costs are deducted.

Liquidity introduces another layer of operational strategy. Although a T-bill is engineered to mature on a fixed date, an investor is not strictly locked in until maturity. Holding the paper to term immunises the investor against subsequent market yield shifts; the final payout remains fixed.

However, an investor needing early access to capital must liquidate the paper on the secondary market. There, the instrument is marked to market: its value fluctuates based on prevailing yield curves, remaining tenure, and interbank liquidity at the time of sale.

According to an analyst who spoke to TechCabal on the condition of anonymity because they’re not authorised to speak to the media, this is one reason money market funds (MMFs) can look attractive to smaller investors. They can hold T-bills alongside other short-term instruments such as commercial papers, giving investors exposure to several assets while allowing the fund manager to handle the underlying transactions.

The trade-off is that investors are no longer holding a single T-bill directly, and the fund has its own fees, risks, and investment strategy.

Ultimately, Nigeria’s T-bill ecosystem is a delicate marketplace balancing public debt requirements against private capital allocation.

The government aims to minimise its cost of debt; primary dealers seek execution margins; wealthtech platforms capture customer acquisition fees and interest spreads; and retail investors chase maximum yields within strict risk boundaries.
