FGN Savings Bond vs. Treasury bills: which government instrument fits small savers
Every few months the same question shows up in savings circles across Nigeria: should the money go into an FGN savings bond or into Treasury bills? Both are backed by the federal government, both beat most bank savings accounts, and both can be opened with amounts that ordinary earners can manage. Yet they behave very differently once you own them, and the wrong pick can leave cash locked away when you need it — or interest trickling in when you wanted a lump sum.
The honest answer is that neither instrument is universally better. Each solves a different problem, and the choice depends far more on your timeline and cash-flow needs than on which headline rate looks bigger that month. This guide walks through how each one works, what they currently pay, how easily you can exit early, and how to decide between them without guesswork.
What each instrument actually is
An FGN savings bond is a retail bond issued monthly by the Debt Management Office in two tenors — two years and three years. When you subscribe, you are lending the federal government money for that period, and in exchange it pays you a fixed interest rate every quarter until maturity, when your principal comes back in full. The design is deliberately retail-friendly: each unit costs ₦1,000, the minimum subscription is ₦5,000, and rates are announced afresh each month, usually with the three-year version paying about one percentage point more than the two-year version.
Treasury bills are shorter. The Central Bank of Nigeria auctions them on behalf of the federal government in three standard tenors — 91 days, 182 days and 364 days — roughly every two weeks. You do not receive periodic interest. Instead, you buy the bill at a discount to its face value and receive the full amount at maturity, with the discount acting as your return. A ₦1,000,000 bill bought at a 15.89% discount rate costs roughly ₦84,200 today and pays ₦100,000 in a year — and because your true outlay is the discounted price, the effective yield works out noticeably higher than the quoted rate.
Both are regarded as the safest naira investments available to individuals, since the full faith of the federal government stands behind repayment. The difference is not safety. It is structure.
What your money currently earns
Rates on both instruments move with the market, so any figure you read today is a snapshot rather than a promise. That said, the recent picture helps make the trade-offs concrete.
In mid-2026, the FGN savings bond was paying around 14.7% per annum on the two-year version and 15.7% on the three-year version, with those rates reset at every monthly offer. Treasury bill stop rates from the September 2026 primary auction sat at roughly 15.50% for the 91-day bill, 15.80% for the 182-day bill and 15.89% for the 364-day bill — and remember that the discount structure means the true yield on the one-year bill ran closer to 19% before tax, comfortably above the headline number. Since late 2025, discount income on Treasury bills attracts 10% withholding tax, which trims the net figure to around 17% on the longest tenor. FGN savings bond interest, by contrast, remains fully exempt from withholding tax and personal income tax under the Nigeria Tax Act 2025 — a genuine advantage that the headline rates do not advertise.
So on paper, a one-year Treasury bill still edges out a two-year savings bond on raw net yield. But the savings bond pays you four times a year instead of once, and the three-year version lets you lock a rate for longer than any Treasury bill tenor allows. Whether that matters depends entirely on what you need the money to do.
Side by side: the numbers that matter
Before committing money anywhere, it helps to see the two instruments next to each other on the features that actually affect small savers day to day.
| Feature | FGN savings bond | Treasury bills |
|---|---|---|
| Minimum investment | ₦5,000 | Varies by channel; banks and agents commonly set their own floors |
| Tenors available | 2 years and 3 years | 91 days, 182 days, 364 days |
| How interest is paid | Fixed coupon every quarter | Lump sum at maturity (sold at a discount) |
| Rate behaviour | Set monthly, fixed for the life of the bond | Reset at every two-weekly auction |
| Tax on returns | Fully exempt | 10% withholding tax on discount income since October 2025 |
| Selling before maturity | Possible on FMDQ via a stockbroker, at market price | Possible in the secondary market, at market price |
| Where to buy | Banks, stockbrokers and licensed investment platforms during the monthly window | CBN primary auction via a bank or authorised dealer, or the secondary market |
Read that comparison slowly and a pattern emerges: the savings bond trades flexibility for predictability, while Treasury bills trade predictability for short cycles and, at recent auctions, a slightly richer net yield. The savings bond also wins decisively on the entry ticket — ₦5,000 opens the door, whereas access to Treasury bills through formal channels often involves larger practical minimums set by the banks and brokers standing between you and the auction.
Liquidity and the cost of changing your mind
Lock-up periods are where many first-time savers get burned, so it is worth being blunt about what happens when plans change. Neither instrument should be treated as a piggy bank, but neither is a prison either — you just pay a price for early access, and the price differs in kind. The realities worth knowing before you commit:
- Selling a savings bond before maturity means going through a stockbroker on the FMDQ secondary market, where the price depends on prevailing interest rates — if market rates have risen since you bought, you may get back less than you invested.
- Treasury bills can also be sold before maturity through the secondary market, and because they mature so quickly anyway, holding to term is usually the smarter move.
- A savings bond’s quarterly coupon creates its own liquidity: even while your principal is locked, cash arrives four times a year, which suits savers who need an income stream rather than a lump sum.
- Treasury bills pay everything at the end, so until maturity you are fully out of pocket — plan for that in your budget.
- Subscription windows matter too: savings bonds are only open for a few days each month, while Treasury bill auctions happen roughly fortnightly, so the savings bond rewards planning.
The practical lesson is that neither instrument is ideal for a genuine emergency fund. Money you might need within weeks belongs in a savings account or a liquid money-market product. These two instruments are for the layer of savings you are confident you can set aside for at least three months — and ideally longer.
Who each one suits
With the mechanics clear, the choice comes down to honest self-assessment. If you are saving towards something roughly two or three years out — school fees, a business launch, a deposit — and you like the idea of cash arriving every quarter, the savings bond fits naturally. If your horizon is shorter, or you simply want your money working at a strong rate without committing beyond a year, Treasury bills are the cleaner match. Many savers end up using both, rotating maturing bills into whatever the current auctions and bond offers are paying.
How to actually get started
Opening either investment is less intimidating than it sounds, and the process for each follows a clear sequence. Whichever route you take, the essentials look like this:
- Decide the amount and check that it genuinely falls within the lock-up period you can tolerate.
- Open the required infrastructure — a CSCS account is needed for savings bonds, while Treasury bills can sit with your bank, a broker or an investment platform.
- For the savings bond, watch for the DMO’s monthly offer window, pick the two-year or three-year tenor and submit through your bank, stockbroker or app before the offer closes.
- For Treasury bills, place a bid through your chosen channel ahead of the next CBN auction, confirming whether your quoted amount is the face value or the discounted sum that will actually leave your account.
- Keep records of your allotment, coupon dates and maturity date, and diarise the maturity so you decide deliberately what happens to the proceeds next.
Step five is the one people skip, and it quietly costs the most. When a bill matures or a bond pays its final coupon, idle money stops earning. Savers who treat each maturity as a decision point — roll over, reinvest elsewhere, or spend — consistently end up better off than those who let funds drift back into a current account.
The bottom line for small savers
The FGN savings bond and Treasury bills are not rivals so much as neighbours on the same street. One hands you a fixed rate, quarterly income and a tax-free return over two to three years, with the lowest entry bar in Nigerian fixed income. The other gives you three, six or twelve months of government-backed parking at rates that have recently matched or beaten the bond — but with a lump-sum payoff, a withholding tax haircut and rates that reset every fortnight.
If you must pick one today with a modest sum and no pressing plans for it, the savings bond is the more forgiving first step: the ₦5,000 minimum, quarterly coupons and tax exemption make it the more natural home for small, patient money. If your timeline is short or you want to stay nimble while rates are this attractive, build a ladder of Treasury bills instead. Either way, you are lending to the same borrower — the federal government — at returns that most bank deposits cannot come close to matching.
