While millions chase crypto pumps and Telegram “double your money” schemes, the Federal Government has quietly been offering something rarer: a near risk-free return of roughly 15–17% a year, backed by its full faith and credit, with interest paid to you upfront. That instrument is the Nigerian Treasury Bill — and in 2026, with yields still attractive and inflation being fought down, more ordinary Nigerians are finally paying attention.
But most guides gloss over the one thing that trips up beginners: the minimum investment. The headline “buy T-Bills from ₦100,000” is only half true, and the CBN’s own primary-market minimum is a jaw-dropping ₦50 million. This guide cuts through it — how T-Bills actually work, the three different minimums and which applies to you, current rates, every buying route, the tax change you must check, and the honest risks.
📌 The quick version: T-Bills are short-term FGN debt (tenors of 91, 182 and 364 days) sold at a discount — you pay less than face value and get the full face value at maturity, so your “interest” is effectively paid upfront. Recent 2026 auction stop rates have sat around 15.9% (91-day), 16.4% (182-day) and 16.4% (364-day). The minimums that actually matter: primary-market (direct CBN auction) ₦50,001,000 — institutional territory; retail access via banks/brokers/apps from about ₦100,000; secondary market from ₦50,001. You buy through a commercial bank, licensed stockbroker/discount house, or a SEC-regulated investment app — open an account (ID, BVN, passport photo), pick a tenor, place your bid around the fortnightly Wednesday auction, and you’re in. Check the current tax position — T-Bill interest has long been tax-exempt for individuals, but tax reforms are changing the landscape, so confirm before you invest.
What a Treasury Bill Actually Is
A Treasury Bill is a short-term loan you make to the Federal Government, issued by the CBN on the government’s behalf to fund short-term needs. Two features make it distinctive. First, it’s a discount instrument: instead of paying you interest at the end, the government sells you the bill below its face value and pays back the full face value at maturity — so if you buy a ₦100,000 bill at a 16% discount rate, you pay roughly ₦86,000 now and receive ₦100,000 later, with the ₦14,000 difference being your return, effectively in your hands from day one. Second, it’s considered as close to risk-free as Nigeria offers: it’s backed by the full faith and credit of the FGN, and the standard line is that if the government couldn’t pay, the CBN could print to settle holders. Tenors are 91 days (3 months), 182 days (6 months) and 364 days (1 year) — you pick based on when you’ll need the cash.
Current Rates (And Why They Move)
Rates are set by auction, not decree, so they shift every fortnight. Through 2026 the stop rates have hovered in the mid-teens — recent auctions showed roughly 15.9% for the 91-day, 16.4% for the 182-day, and 16.4% for the 364-day bill, easing gently from earlier cycle highs as the CBN works liquidity down. Demand is ferocious: at one 2026 auction the 364-day bill drew ₦2.73 trillion in subscriptions against a ₦200 billion offer — institutions clearly trust the instrument.
Two honest caveats. These are nominal rates, not real returns — if inflation runs above your rate, your purchasing power can still slip even as your naira balance grows. And rates change at every auction, so any figure you read (including here) is a snapshot; always confirm the live stop rate before bidding.
The Minimums — Explained Properly
This is where beginners get misled, so here’s the truth in three tiers:
Primary market (direct at the CBN auction): ₦50,001,000. Per DMO guidelines, bidding directly in the primary auction requires a minimum of just over ₦50 million, in multiples of ₦1,000. This is institutional and high-net-worth territory — not where an ordinary saver starts.
Retail access (via banks, brokers and apps): from about ₦100,000. Banks and licensed platforms aggregate smaller investors’ money to access the market on your behalf, so most retail investors can start from roughly ₦100,000 (some apps go lower). You’re still getting genuine T-Bill exposure — just arranged through an intermediary rather than bidding ₦50m yourself.
Secondary market: from ₦50,001. Previously issued T-Bills trade between investors daily (Monday–Friday) through authorised dealers, with a much smaller entry point around ₦50,001 — useful if you want in between auctions or need to exit early.
So the practical answer to “how much do I need?” is: around ₦100,000 through a bank or app, not ₦50 million. Just know which door you’re walking through.
How to Buy: The Step-by-Step
The clean workflow, whichever intermediary you use:
1. Choose where to buy — a commercial bank (many now let you buy in-app with a tap), a licensed stockbroking/discount house, an asset-management firm, or a SEC-regulated investment app. Pick a regulated provider; ignore “T-Bill” offers from unlicensed Telegram operators.
2. Open a Treasury Bills investment account — provide a valid ID, passport photograph, BVN and your bank account details. Existing bank customers can often skip most of this.
3. Pick your tenor — 91, 182 or 364 days, matched to when you’ll need the money. Longer tenors usually pay a little more; never lock in money you’ll need next month.
4. Decide your amount — start from your intermediary’s minimum (around ₦100,000 for most retail platforms), keeping a separate emergency buffer untouched.
5. Place your bid — the primary auction runs roughly every two weeks on Wednesdays. You can bid competitively (you name the rate you’ll accept — risk being “bid out” if you ask too high) or non-competitively (you accept the auction’s determined rate — simpler, and what most retail buyers effectively do through their bank). Your intermediary submits it.
6. Get funded and confirm — if successful, your account is debited the discounted amount (interest effectively paid upfront), and your holding is confirmed. At maturity, the full face value lands in your account.
Managing Your Investment: Maturity, Rollover, Early Exit
Two decisions follow every purchase. At maturity, you choose to take the cash or roll over (reinvest principal, and often the interest, into the next auction) — rollover compounds your money and is the quiet engine of T-Bill wealth-building; set it deliberately rather than by default. Before maturity, if you need funds early, T-Bills are liquid: you can sell in the secondary market through your dealer, though the price you get depends on prevailing rates (if rates have risen since you bought, you may sell at a slight loss; if they’ve fallen, possibly a gain). They also work as collateral for bank loans and count as liquid assets for visa applications — underrated side benefits.
The Tax Question You Must Check
For years, a major attraction was simple: interest on Treasury Bills was tax-exempt for individual investors, letting you keep the full return. But Nigeria’s 2026 tax reforms are reshaping the fiscal landscape, and the tax treatment of investment income is exactly the sort of thing under review. Do not assume the old exemption still applies in full — ask your bank, broker or a tax adviser what the current position is before you invest, and factor any withholding tax into your expected net return. This single check can be the difference between the return you imagined and the one you actually keep.
Is It Right for You? An Honest Take
T-Bills are excellent for capital preservation and predictable, low-risk returns — an emergency fund’s serious cousin, a home for money you’ll need in a year, a calm anchor against volatile assets. They are not a get-rich vehicle: mid-teens returns are solid, not spectacular, and in high-inflation spells your real return can be thin. If you’re just building an investment habit with small sums, a money market fund or the FGN Savings Bond (from just ₦5,000, quarterly interest, 2–3 year tenors) may be a gentler first step — different products, so compare tenor, liquidity and yield. But for most Nigerians sitting on idle savings earning near-nothing in a current account, moving some into T-Bills is one of the most sensible financial decisions available in 2026.
FAQ: Treasury Bills in Nigeria 2026
1. How much do I need to start?
Through a bank, broker or investment app, typically from about ₦100,000. Bidding directly at the CBN primary auction requires ₦50,001,000 — but intermediaries let retail investors in far below that. The secondary market starts around ₦50,001.
2. What returns can I expect?
Recent 2026 auctions have paid roughly 15.9% (91-day) to 16.4% (182/364-day) per annum — but rates change every auction, so confirm the live stop rate before investing.
3. How does the discount work?
You buy below face value and receive full face value at maturity. Buy a ₦100,000 bill at ~16% and you pay about ₦86,000 now, getting ₦100,000 later — so your interest is effectively paid upfront.
4. What tenors are available?
91 days (3 months), 182 days (6 months) and 364 days (1 year) in the primary market; the secondary market offers a wider range of remaining maturities.
5. How do I actually buy?
Open a T-Bills account with a commercial bank, licensed stockbroker/discount house or SEC-regulated app (ID, BVN, passport photo), pick a tenor and amount, and place your bid around the fortnightly Wednesday auction.
6. Are Treasury Bills safe?
They’re among the safest investments in Nigeria — backed by the full faith and credit of the FGN, with negligible default risk. The main “risk” is inflation eroding your real return.
7. Can I sell before maturity?
Yes — via the secondary market through your dealer. Your sale price depends on prevailing rates, so you may realise a small gain or loss versus holding to maturity.
8. Is the interest taxed?
T-Bill interest has traditionally been tax-exempt for individuals, but 2026 tax reforms may change this. Confirm the current position with your bank, broker or a tax adviser before investing.
9. What’s a competitive vs non-competitive bid?
Competitive: you specify the rate you’ll accept (and risk being bid out if too high). Non-competitive: you accept the auction’s determined rate — simpler, and effectively how most retail buyers participate through their bank.
10. T-Bills or FGN Savings Bond for a beginner?
If you have small sums, the FGN Savings Bond (from ₦5,000, quarterly interest, 2–3 years) is a gentler entry. T-Bills suit those with at least ~₦100,000 who want short-tenor, discount-priced exposure. Compare tenor, liquidity and yield.
The Bottom Line
Treasury Bills are the quiet, unglamorous, near-risk-free instrument that too many Nigerians overlook while gambling elsewhere. In 2026 they’re paying around 15–17%, backed by the Federal Government, with interest in your hands upfront. Ignore the ₦50 million headline — through a bank, licensed broker or SEC-regulated app you can start from roughly ₦100,000 — open an account, pick a tenor that matches your timeline, bid around the fortnightly auction, and decide upfront whether you’ll roll over at maturity.
Do two things before you commit: confirm the live auction rate and check the current tax treatment under the 2026 reforms. Get those right, keep an emergency buffer aside, and let a portion of your idle savings finally start working — safely — for you.
