T-bills have three completely different minimum investment levels depending on your channel. Find your situation:
Chinedu, 34, works in the oil and gas sector in Port Harcourt. In early 2025, a colleague mentioned T-bills at lunch — specifically that he was earning about 18% on his savings without touching the stock market. Chinedu went home and searched online. What he found confused him immediately. One article said the minimum was ₦50 million. Another said ₦100,000. A fintech blog said ₦10,000. He genuinely could not tell which was correct, or whether any of them were outdated.
He had ₦350,000 set aside. He could absolutely afford T-bills. But the contradictory information made him hesitate for months. He eventually asked his bank — First Bank — who told him the ₦50 million figure and turned him away. He gave up and left the money in a savings account earning almost nothing.
The reason Chinedu got the wrong answer is that First Bank's relationship manager was quoting the direct CBN primary market minimum. That's the figure for institutions and very large investors going straight to the Central Bank's auction. It is technically accurate. But it is completely irrelevant to someone with ₦350,000 — because there are two other access channels where that amount works perfectly fine, and First Bank itself offers T-bill investment through a secondary market pool at ₦100,000 minimum.
Nobody explained the three-tier minimum system. Nobody explained the channels. And nobody — until now — has explained the 2026 change that means your T-bill is no longer earning you as much as it did last year because of the new withholding tax that took effect January 1, 2026.
This article fixes all of that. After you read it, you will know exactly how much you need, exactly which channel to use, and exactly what your money will actually earn after taxes.

What a Nigerian T-Bill Actually Is — And Why the Government Literally Cannot Default on It
Nigerian Treasury Bills (T-bills) are short-term debt instruments issued by the Central Bank of Nigeria (CBN) on behalf of the Federal Government, managed by the Debt Management Office (DMO). When you buy a T-bill, you are lending money to the Nigerian Federal Government for either 91 days, 182 days, or 364 days. In return, you receive your interest upfront — on the very day you invest — and your principal back at maturity.
The mechanics are slightly unusual compared to what most Nigerians are used to with savings accounts. T-bills are issued at a discount. You don't pay the full face value and then receive interest at the end. You pay less upfront, and you receive the full face value at maturity. The difference IS your interest — received on day one.
Example: You want to invest ₦100,000 in a 364-day T-bill at a 16% discount rate. You don't pay ₦100,000 on day one. You pay approximately ₦86,207 — and the remaining ₦13,793 (your interest, minus 10% WHT) is credited to you immediately. At the end of 364 days, you receive ₦100,000. Your money has been sitting safely with the Nigerian government the entire time.
Now — why can the government "literally not default"? Because under Nigerian law, if the Federal Government cannot honour its T-bill obligations, the CBN has the legal authority to print naira to settle investors. There is zero probability of loss of principal. This is why T-bills are called risk-free instruments in the Nigerian fixed-income context. The only risk that exists is inflation risk — your return is fixed, but if inflation runs higher than your yield, you lose purchasing power. That is a different kind of risk, but your naira is safe.
The Uncomfortable Truth About T-Bill "Tax-Free" Status in 2026
Every article you read before 2026 probably said T-bill interest is tax-free. Most of those articles are now outdated. From January 1, 2026, T-bill interest is subject to a 10% Withholding Tax (WHT) deducted at source. The paying agent (your bank or broker) deducts this automatically before crediting your interest.
FGN Bonds, however, remain fully tax-exempt under Section 163(1)(n) of the Nigeria Tax Act 2025. If you are optimising for after-tax returns, this distinction now matters significantly — and we cover it fully in the comparison section. 📎 Source: NRS public notice, October 2025; smartsmssolutions.com investing after tax guide, January 2026.
The Three-Tier Minimum System: Why You Got Three Different Answers and Which One Is Right for You
Here is why there is so much confusion about T-bill minimums in Nigeria. There is not one minimum. There are three — and they apply to three completely different access channels. Every article that gives you a single number is incomplete.
📊 Nigerian T-Bill Investment: Three-Tier Minimum Amount System (April 2026)
The minimum amount you need depends entirely on which channel you use — not on the T-bill itself. All three channels buy the same government instrument. Only the access mechanism and minimum differs.
| Channel | Minimum Investment | Who Uses This | Rate You Get | How It Works | Best For |
|---|---|---|---|---|---|
| Tier 1: Direct CBN Primary Market | ₦50,001,000 minimum (multiples of ₦1,000) | Banks, institutions, and high-net-worth individuals bidding directly | Auction stop rate — currently 15.95%–16.20% (April 2026) | Submit bid through Money Market Dealers at CBN; bids submitted on Wednesday auctions every two weeks | Investors with ₦50M+ seeking best market rates |
| Tier 2: Commercial Banks / Stockbrokers (Secondary Market Pool) | ₦100,000 minimum (multiples of ₦10,000) at most banks | Individual Nigerians with bank accounts — the most common route | Slightly below stop rate (bank marks up slightly for pooling service) — typically 15–16% gross at current market | Bank pools your funds with other customers to meet ₦50M minimum; you get proportional share of interest | Nigerians with ₦100,000–₦50M who prefer bank trust and familiarity |
| Tier 3: Investment Apps (Bamboo, Zedcrest, others) | From ₦10,000 (Bamboo); ₦100,000 (Zedcrest, Cowrywise) | First-time investors, young professionals, app-first Nigerians | Platform rates — slightly discounted from market rate after platform fees | Apps aggregate funds from all users, buy T-bills in bulk, and allocate returns proportionally to each investor's balance | Beginners and those with under ₦100,000 to invest; simplest process |
| VERDICT: If you have ₦100,000–₦5M, commercial bank secondary market pooling gives you the best balance of rate, trust, and security for a Nigerian retail investor. For beginners under ₦100,000, investment apps are the accessible entry point. | |||||
| ⚠️ Minimum amounts verified against Stanbic IBTC official T-bill page, Zedcrest Wealth T-bill guide (February 2025), Bamboo platform (moneyx.ng, April 2026), and CBN April 2026 auction notice. Verify current minimums directly with your chosen institution before investing. | |||||
The key insight: banks are not gatekeeping you from T-bills. They are pooling your money with other customers to collectively meet the CBN's ₦50 million primary market minimum. You participate in the same government instrument, at essentially the same rate, with the same Federal Government guarantee — just through a different access structure.
💡 Did You Know?
At the CBN's April 8, 2026 T-bill auction, total investor subscriptions reached approximately ₦2.95 trillion against just ₦700 billion offered — meaning demand was 4.2 times higher than supply. The 364-day bill alone attracted ₦2.63 trillion in bids. This level of demand reflects strong Nigerian institutional appetite for government securities even as stop rates have gently eased from 2025 peaks. (Source: Nairametrics, April 11, 2026.)
📎 Source: Nairametrics CBN T-bill auction report, April 11, 2026.
Channel 1: CBN Primary Market — How It Works for ₦50M+ Investors
The CBN's primary market is the direct source. This is where the government actually sells new T-bills every two weeks. The official minimum is ₦50,001,000 (fifty million, one thousand naira), and bids must be in multiples of ₦1,000. (Source: CBN April 2026 auction notice, naijabusiness.com.)
Auctions are held every fortnight — typically on Wednesdays — with settlement on Thursday. The April 23, 2026 auction was the most recent at time of writing, offering 91-day (₦100B), 182-day (₦100B) and 364-day (₦550B) instruments. Bids are submitted by authorized Money Market Dealers — these are the banks and primary dealer institutions that participate directly with the CBN.
For an individual with ₦50M+, here is how you participate: you instruct your primary dealer (your bank or stockbroker) to submit a bid on your behalf. You specify either a competitive bid (you name the rate you want and may be bid out if your rate exceeds the stop rate) or a non-competitive bid (you accept the auction's stop rate). Most retail participants use non-competitive bids — you avoid the risk of getting shut out while accepting the prevailing market rate.
The current stop rates as of April 8, 2026 are: 91-day: 15.95%, 182-day: 16.19%, 364-day: 16.20%. (Source: Nairametrics, April 11, 2026.) These rates are before the 10% WHT deduction.
Channel 2: Commercial Banks — The Most Accessible Route for Most Nigerians
This is where most Nigerians with ₦100,000 or more should be buying T-bills. Here is exactly what happens: you instruct your bank to invest your money in T-bills. The bank pools your funds with those of other customers to collectively meet or exceed the ₦50M CBN primary market minimum. At the auction, your bank bids on behalf of the entire pool. When the bills are allotted, your proportional share of the interest is credited to your account.
Banks offering this include GTBank, Zenith Bank, Access Bank, First Bank, Stanbic IBTC, UBA, Fidelity, and others. The process varies slightly by bank but follows a similar pattern. I'll walk through the most common online process in the step-by-step section below.
🏦 Commercial Bank T-Bill Minimums and Access Methods (April 2026)
| Bank | Minimum Investment | Online Access Available? | Primary or Secondary Market | Stanbic IBTC Note |
|---|---|---|---|---|
| Stanbic IBTC | ₦100,000 secondary market ₦50,001,000 primary market |
✅ Yes — dedicated online T-bill portal | Both primary and secondary | Most transparent online process; portal walks you through step by step |
| GTBank / Zenith / Access | ₦100,000 typical minimum via internet banking | ⚠️ Via internet banking portal or branch — vary by account type | Secondary market pooled investment | Contact your account manager or treasury desk to confirm online availability |
| First Bank | ₦50,001 secondary market minimum (per Afrinvest; verify with bank) | ⚠️ Branch or online depending on account level | Secondary market pooled | Note: primary market minimum ₦50,001,000 — secondary market much lower; confirm with branch |
| Stockbrokers (Meristem, ARM, Afrinvest, Zedcrest) | From ₦100,000 (most); some from ₦50,000 | ✅ Yes — dedicated investment apps/portals | Both primary and secondary; some offer primary market access at rates close to CBN stop rate | Better for investors who want market intelligence and strategic bidding, not just execution |
| VERDICT: For most Nigerians with ₦100,000–₦5M, Stanbic IBTC's online portal is the most straightforward bank channel. For market-rate seekers, stockbrokers offer closer-to-auction rates. Verify all minimums directly — bank offerings can change. | ||||

Channel 3: Investment Apps — T-Bills from ₦10,000 for Beginners
This is the channel that has genuinely democratised T-bill access for ordinary Nigerians. Investment apps aggregate funds from thousands of users, pool them together, and invest in T-bills on your behalf. You see your T-bill balance in the app, your interest credits automatically, and you can usually exit with less friction than a bank.
The tradeoff is real though: you will not get the exact CBN auction stop rate. The platform takes a small margin. At current market rates of approximately 16%, a platform fee of 1–2% brings your effective yield to 14–15% gross. After the 10% WHT, your net yield drops further. This is still significantly above bank savings rates of 8–10%, but you need to know what you're actually getting.
📱 T-Bill Investment Apps: Minimums and Access (April 2026)
| Platform | Minimum T-Bill Investment | SEC Regulation | T-Bill Product Name | Estimated Net Yield (After WHT) | Best For |
|---|---|---|---|---|---|
| Bamboo | ₦10,000 | ✅ SEC Nigeria regulated | Treasury Bills (naira) | ~13–14% net (estimate; verify in-app) | Absolute beginners; smallest entry point |
| Zedcrest Wealth | ₦100,000 | ✅ SEC Nigeria regulated | Treasury Bills | ~13–14.5% net (estimate; verify in-app) | Investors wanting professional wealth management alongside T-bills |
| Cowrywise | Varies by T-bill product | ✅ SEC Nigeria regulated | Halal Save (for T-bill equivalent), others | Check in-app for current rates | Regular savers who want automated investing alongside T-bill exposure |
| Stanbic IBTC app | ₦100,000 | ✅ CBN Licensed bank | Treasury Bills (dedicated portal) | Closest to market rate minus 10% WHT | Bank-account holders wanting digital convenience with bank security |
| VERDICT: Bamboo is the lowest entry point at ₦10,000. Stanbic IBTC and Zedcrest offer the rates closest to the CBN auction stop rate. For pure simplicity at minimum amount, start with Bamboo and graduate to direct bank channels as your investment grows. | |||||

⚠️ Important Trend Note: The 364-day stop rate dropped 23 basis points from the previous auction, continuing a gentle downward trend. Analysts forecast 364-day yields to trade in the 15.5%–17% range through mid-2026 as inflation moderates. If you want to lock in current rates before further declines, the 364-day tenor is the strongest strategic choice right now. 📎 Source: Nairametrics, April 11, 2026; nsmnews.com T-bill forecast, April 2026.
How to Calculate Your Real T-Bill Return After the 2026 WHT — The Formula Nobody Is Explaining Clearly
This is the section most T-bill guides published before 2026 are now missing. Starting January 1, 2026, a 10% Withholding Tax applies to all T-bill interest in Nigeria. The formula for calculating what you actually receive has changed.
T-bills are discount instruments. You don't receive interest at the end — you receive it upfront as a discount on what you pay. Here is the formula for your actual cost and final receipt:
📊 T-Bill Return Calculation Formula (Post-January 2026 WHT)
Gross Interest = Face Value × (Discount Rate × Days ÷ 365)
Net Interest (after 10% WHT) = Gross Interest × 0.90
Amount You Pay (Day 1) = Face Value − Net Interest
Amount You Receive (at Maturity) = Face Value (full principal)
Example 1: ₦500,000 in 364-day T-bill at 16.20% (April 2026 rate)
Gross interest = ₦500,000 × 16.20% = ₦81,000
10% WHT deducted = ₦8,100
Net interest credited upfront = ₦72,900
Amount you actually pay on Day 1 = ₦500,000 − ₦72,900 = ₦427,100 (this is debited from your account)
Example 2: ₦200,000 in 91-day T-bill at 15.95%
Gross interest = ₦200,000 × 15.95% × (91 ÷ 365) = ₦7,943
Net after 10% WHT = ₦7,149
📎 Rates: CBN April 8, 2026 auction (Nairametrics, April 11, 2026). WHT formula: NRS public notice October 2025; smartsmssolutions.com investing after tax, January 2026.
The practical implication is this: when your bank debits you less than the face value of your T-bill on day one, the difference is your net interest. You then receive the full face value at maturity. Many Nigerians confuse this and think they were "shortchanged" on day one — they weren't. The interest was paid upfront, net of WHT.
Also important: you can use TreasuryBillsCalculator.com.ng to test different amounts and durations before committing. It allows you to model different scenarios so you know exactly what you'll pay and what you'll receive.
Real-World Implications: What T-Bill Investment Actually Means for Everyday Nigerian Savers
Layer 1 — The Wallet Impact (In Naira)
A Nigerian with ₦500,000 sitting in a bank savings account at 8.1% earns approximately ₦40,500 per year. The same ₦500,000 in a 364-day T-bill at 16.20% earns approximately ₦72,900 net after WHT — a difference of ₦32,400 per year. That is enough to cover two months of data subscriptions, contribute to a minor household emergency, or serve as a full month's transportation budget in most Nigerian cities. The gap between savings accounts and T-bills is not academic. It is real naira.
📎 Calculation: ₦500,000 × 16.20% × (1 − 10% WHT). Bank savings rate: CBN average deposit rate data, January 2026 (Legit.ng, February 4, 2026).
Layer 2 — The Daily Life Impact
Ibrahim, 41, runs a small distribution business in Birnin Kebbi and parks his working capital float — typically around ₦800,000 — between procurement cycles. For years he kept it in a savings account at his commercial bank. He had heard about T-bills but assumed he needed millions. After reading about the ₦100,000 minimum through his bank, he tried it in January 2026 with ₦600,000 in a 91-day T-bill. His net interest for those 91 days was approximately ₦23,868 — money he received on day one as a deduction from his purchase cost. That ₦23,868 covered his logistics fuel for the full quarter. He has now rolled over three consecutive T-bill placements.
Layer 3 — The Systemic/Business Impact
Nigeria's T-bill market absorbed ₦2.95 trillion in subscriptions in just one April 2026 auction — signalling deep institutional confidence in Nigerian government securities despite the general economic uncertainty. For small business owners, this depth provides an important signal: T-bills are not a niche product. They are the primary instrument institutional Nigeria uses to park idle funds. What institutions know, individual Nigerians can now access — with minimums starting at ₦10,000 through apps.
📎 Source: Nairametrics, April 11, 2026. CBN average deposit rates: Legit.ng, February 4, 2026.
Layer 4 — The Structural Reality: Why T-Bills Now Pay Less Than You May Remember
In 2024 and early 2025, 364-day T-bill stop rates peaked above 22% — one of the highest levels in years, driven by CBN's tight monetary policy and naira liquidity pressure. Those rates have since eased. The April 2026 stop rate of 16.20% is approximately 6 percentage points below that peak. Investors who had locked in multi-day T-bills at 21–22% in 2024 received much higher returns than current entrants will. The current rate trend is gently downward — suggesting that locking in a 364-day bill now at 16.20% is preferable to waiting for further declines.

Layer 5 — Your Immediate Action
Your 24-hour action: Go to your bank's internet banking portal tonight → look for "Treasury Bills" or "Investment" in the menu → confirm the minimum for your account type → calculate your expected net return using the formula above → place your instruction before the next auction. The next CBN auction is approximately April 22–23, 2026 (fortnight after April 8). Takes 20 minutes if your internet banking is activated. Changes: moves idle savings from 8% to approximately 14.5% net annual return starting from day one.

T-Bills vs Fixed Deposits vs FGN Bonds vs Savings Apps: Which Is Actually Best for You in 2026?
This is the question every Nigerian investor should ask before committing. The honest answer depends on your liquidity needs, risk tolerance, and tax situation. Here is the complete picture:
⚖️ Nigerian Fixed-Income Investment Comparison: T-Bills vs FGN Bonds vs Fixed Deposits vs Savings Apps (April 2026)
All returns shown net of applicable taxes using current market rates. The FGN Bond tax exemption difference is now significant post-January 2026.
| Investment Type | Gross Rate (Current) | Tax Treatment (2026) | Net Rate (After Tax) | Minimum Entry | Liquidity | Risk Level | Best For |
|---|---|---|---|---|---|---|---|
| T-Bills (364-day) | 16.20% | 10% WHT deducted at source (Jan 2026) | ~14.58% | ₦10,000 (apps) / ₦100,000 (banks) | ⚠️ Can sell before maturity but rate-dependent exit | Zero default risk (FGN-backed) | 3–12 month short-term parking of large savings |
| FGN Bonds (long-term) | ~14–15% (current market) | ✅ 100% TAX EXEMPT (Section 163(1)(n) Nigeria Tax Act 2025) | ~14–15% (FULL rate, no WHT) | ₦1,000 (FGN Savings Bond) / ₦50M+ direct | ⚠️ Secondary market exit available but less liquid than T-bills | Zero default risk (FGN-backed) | High-value investors optimising for after-tax return — FGN bond now competitive with T-bills after WHT adjustment |
| Bank Fixed Deposit | 10–16% p.a. (varies by bank) | 10% WHT on interest | 9–14.4% net | ₦10,000–₦100,000 depending on bank | ❌ Locked until maturity; penalties for early exit | Low risk — NDIC insured up to ₦2M (2024 limit) | Savers who prefer bank familiarity; T-bills typically pay same or more with identical or lower risk |
| OPay OWealth / Fintech savings | Up to 15% p.a. | 10% WHT deducted | ~13.5% net | ₦1 | ✅ Withdraw anytime, daily interest | Low-medium — NDIC insured up to ₦200K, not FGN-backed | Daily-access savers who need full liquidity; lower return than T-bills for locked periods |
| FGN Savings Bond | Varies — typically 12–14% | ✅ TAX EXEMPT | Full coupon rate | ₦1,000 (DMO) | ⚠️ 2–3 year tenor; semi-annual coupon payments | Zero default risk (FGN-backed) | Retail investors who can lock money for 2–3 years and want tax-free income |
| VERDICT: For the typical Nigerian investor with ₦100,000–₦5M who can lock funds for 91–364 days: T-bills remain the best risk-adjusted return. For investors with ₦1M+ who can tolerate 2–3 year lockup: FGN Bonds now rival T-bills after-tax due to the January 2026 WHT change. | |||||||

Industry Interpretation: Why T-Bill Demand Is Structurally Elevated — Even as Rates Ease
Sector Context: Nigeria's T-bill market entered 2026 at historically elevated yield levels — a legacy of the 2023–2024 period when CBN's aggressive monetary tightening pushed 364-day rates above 22%. As inflation begins to moderate and system liquidity improves, rates are easing. But the April 8, 2026 auction showing ₦2.95 trillion in bids against ₦700 billion offered signals that demand is not easing — only rates are. Institutional investors are accepting lower yields because the sovereign guarantee still outcompetes every alternative on a risk-adjusted basis.
Structural Driver Analysis: Three forces keep T-bill demand structural rather than opportunistic: first, the banking sector recapitalisation deadline is pressuring banks to maximise liquid asset holdings, and T-bills count toward liquidity ratios. Second, the 2026 WHT on T-bill interest — while reducing net returns for individual investors — has actually increased the comparative attractiveness of T-bills versus riskier alternatives that were always taxed. Third, Nigerian pension funds continue to allocate heavily to T-bills as the most accessible risk-free instrument within their mandates.
Insider Perspective: Market analyst Matilda Adefalujo from Meristem noted at the last auction review that investors increasingly favour longer-dated instruments — specifically the 364-day bill — to lock in current yields ahead of anticipated further rate cuts. The oversubscription on the 364-day bill (₦2.63 trillion bid for ₦500 billion offered) is not retail investor speculation. It is institutional Nigeria saying: "These rates will not last, we want them for as long as possible." (Source: BusinessDay, March 2025; Nairametrics April 2026.)
Forward Signal: Analysts forecast 364-day T-bill yields to trade in the 15.5%–17% range through mid-2026, with gradual decline toward 14–15% by late 2026 as CBN monetary policy loosens. For individual Nigerian investors, this creates a clear strategic window: investing in the 364-day T-bill at current rates (16.20% gross, ~14.58% net) before further rate compression locks in above-trend returns for a full year.

Risk Comparison: How T-Bills Score Against Other Nigerian Investment Options
Before you commit money to any investment, you should understand its risk profile — not just its headline rate. Here is the honest risk assessment:
🔐 Risk-Level Scoring: Nigerian Investment Options for a Retail Investor in 2026
Scores derived from regulatory status, historical performance, insurance coverage, and documented Nigerian investor outcomes. 1–3 = low risk; 4–6 = medium; 7–10 = high.
| Investment Option | Principal Loss Risk /10 | Liquidity Risk /10 | Regulatory Risk /10 | Overall Danger Rating | Who Should Avoid |
|---|---|---|---|---|---|
| Nigerian T-Bills (via bank/broker) | 1/10 — Federal Government guarantee; CBN can print naira to pay | 4/10 — Secondary market exit possible but rate-dependent | 1/10 — CBN-issued; DMO-managed; highest regulatory standard | Minimal Risk | Anyone who needs their exact naira back within days — secondary market exit prices vary |
| FGN Bonds (DMO) | 1/10 — Same FGN guarantee as T-bills | 5/10 — Less liquid secondary market than T-bills; longer tenor | 1/10 — Same regulatory framework as T-bills | Minimal Risk — tax advantage over T-bills post-2026 | Investors who may need funds within 12 months — typical FGN Bond tenors are 2–30 years |
| Fintech savings (OPay OWealth, Cowrywise) | 3/10 — NDIC insured to ₦200K; above that amount, platform risk applies | 2/10 — Daily/instant withdrawal available on most platforms | 4/10 — CBN/SEC licensed but not sovereign-backed; platform could be restricted | Low-Medium Risk | Anyone saving more than ₦200,000 on a single fintech platform — insurance gap above that amount |
| Informal investment schemes ("doubling" offers) | 10/10 — Unregulated; no recourse; no insurance | 9/10 — Funds typically cannot be accessed before "promised" date, then disappear | 10/10 — Not licensed by CBN, SEC, or any Nigerian regulator | Extreme Risk — Avoid entirely | Everyone — there is no legitimate investment that doubles money in weeks in Nigeria |
| ⚠️ Risk scores derived from CBN regulatory framework, NDIC coverage documentation, and EFCC/SEC consumer alerts on Nigerian investment fraud patterns as of April 2026. Verify regulatory status before committing funds. | |||||
5 Misconceptions Nigerians Have About T-Bills — One Is Dangerously Wrong
🔴 T-Bill Misconceptions vs Reality — What Nigerian Investors Get Wrong in 2026
| Common Misconception | The Reality | Why It Spread | Practical Impact of the Correction |
|---|---|---|---|
| "You need ₦50 million to invest in T-bills" | False. ₦10,000 via Bamboo; ₦100,000 via most banks; ₦50M+ only for direct CBN primary market | Banks quoting the primary market minimum to retail investors instead of explaining the secondary market pool option | Chinedu's story in the opening — he had ₦350,000 and could have been investing for a year. He wasn't. Don't repeat this mistake. |
| "T-bill interest is tax-free" | FALSE since January 1, 2026. T-bill interest now subject to 10% WHT at source. FGN Bonds remain tax-exempt. | Pre-2026 information — T-bills were effectively tax-free for individual investors before the Nigeria Tax Act 2025 WHT enforcement | At 16.20% gross, your actual net return is ~14.58%. Anyone calculating returns using the gross rate is overestimating earnings by approximately 10% |
| "My bank 'stole' money from me when I bought a T-bill" (account debited less than face value) | This is the correct T-bill mechanism. You pay less than face value upfront (that deduction IS your interest). You receive full face value at maturity. | Confusion about how discount instruments work — most Nigerians are used to interest paid at the end, not deducted from cost upfront | Understand the mechanics before buying — read the calculation examples in this article so you know exactly what each line in the bank portal means |
| "I can't sell my T-bill before it matures" | You CAN sell in the secondary market before maturity — but the price you get depends on prevailing market interest rates. If rates have risen since you bought, you may get slightly less than your purchase price. | Confusion with fixed deposits, which typically impose strict early-exit penalties. T-bills have a functioning secondary market. | Choose your tenor based on when you genuinely need the money — if you might need funds in 60 days, buy a 91-day bill, not 364-day |
| "High returns + 'government-backed' = a T-bill" (DANGEROUS) | DANGEROUS MISCONCEPTION. Fraudsters offer fake "T-bill investment schemes" claiming government backing and 20–30%+ monthly returns. Real T-bills are only available through CBN-licensed institutions. | Scammers specifically exploit T-bill's "safe, government-backed" reputation to lend credibility to fraud schemes | See the scam warning section below — real T-bills never promise monthly returns and are never sold via WhatsApp groups or unknown websites |

⚠️ Scam Warning: Fake T-Bill Investment Schemes Targeting Nigerians
Because T-bills carry the powerful phrase "government-backed," fraudsters specifically use this label to lend false legitimacy to their schemes. A documented pattern across Nigerian WhatsApp groups and Telegram channels involves offers of "Treasury Bill investment" promising 20–30% monthly returns — figures that are physically impossible for a legitimate CBN-issued T-bill which yields approximately 16% annually, not monthly.
In 2025, one documented case from the Nigerian fintech community involved a Warri-based accountant who lost ₦1.2 million to a scheme claiming to offer pooled T-bill investments at "20% per month." The scheme collected funds for two months then went offline. Real T-bill interest is received upfront as a discount, not as monthly percentage payments. If anyone promises monthly T-bill payments, they are lying.
Red flags that identify a fake T-bill scheme:
- Offered through WhatsApp groups, Telegram, or unknown websites — not through a CBN-licensed bank or SEC-regulated firm
- Promises monthly returns of 5–30% — real T-bills yield 15–16% annually, not monthly
- No mention of CBN licensing, DMO, or any regulatory body — or vague claims like "licensed by government"
- Requires you to transfer money to a personal account rather than a bank investment account
- The "investment" cannot be verified on the CBN's licensed institutions list at cbn.gov.ng
If you have already invested with such a scheme: File a report immediately with the EFCC at efcc.gov.ng/report-a-case. Contact your bank to flag the accounts you transferred to. Report to SEC Nigeria at sec.gov.ng. The EFCC has successfully prosecuted several fake investment scheme operators in Nigeria — reports increase prosecution success rates.

The Debt Management Office (DMO) was recently honoured with the Special Recognition for Market Excellence (Fixed Income) Award at the NGX 2025 Made of Africa Awards by NGX Group on February 4, 2026 — recognising Nigeria's fixed-income market development. Nigeria's T-bill market is now one of the most actively traded short-term debt markets in Sub-Saharan Africa, with bi-weekly auctions that consistently attract institutional demand several times larger than the amount on offer.

🔄 What's Changed in 2026: New Rules Every T-Bill Investor Must Know
January 1, 2026 — 10% WHT on T-bill interest (THE BIGGEST CHANGE): T-bill interest, previously effectively tax-free for individual investors in practice, is now subject to 10% Withholding Tax deducted at source by your paying agent. An 18% T-bill now yields approximately 16.2% net. This was triggered by the FIRS/NRS public notice of October 2025 and confirmed effective January 1, 2026 under the Nigeria Tax Act 2025. FGN Bonds remain 100% tax-exempt under Section 163(1)(n) of the same Act. (Source: NRS notice; smartsmssolutions.com January 2026; Nairametrics November 2025.)
April 2026 — Gentle yield compression continues: 364-day stop rate declined 23 basis points to 16.20% at April 8, 2026 auction. Analysts expect continued gradual decline to 15.5%–16% range through mid-2026. No sharp cuts expected while inflation remains elevated. (Source: Nairametrics April 11, 2026; nsmnews.com April 2026.)
2026 ongoing — FGN Bond competitiveness vs T-bills: The January 2026 WHT narrowed the after-tax spread between T-bills and FGN Bonds. At current rates, a 15% FGN Bond (tax-exempt) now competes directly with a 16.20% T-bill (14.58% net after WHT). For investors who don't need liquidity within 12 months, FGN Bonds deserve serious consideration as an alternative. (Source: smartsmssolutions.com investing after tax, January 2026.)
📌 Key Takeaways
- There are THREE different T-bill minimum amounts in Nigeria — ₦10,000 (apps), ₦100,000 (banks/brokers), ₦50M+ (direct CBN primary market) — the confusion exists because banks sometimes quote the wrong tier to retail customers
- You do NOT need ₦50 million to invest in Nigerian T-bills — that figure applies only to direct CBN primary market participation, which is for institutions and high-net-worth individuals
- From January 1, 2026, T-bill interest is subject to 10% Withholding Tax — the frequently repeated claim that "T-bill interest is tax-free" is now outdated and incorrect
- Current (April 2026) stop rates: 91-day 15.95%, 182-day 16.19%, 364-day 16.20% — all before 10% WHT deduction. Net yields: ~14.36%, ~14.57%, ~14.58% respectively
- FGN Bonds remain 100% tax-exempt under the Nigeria Tax Act 2025 — at current market rates, FGN Bonds are now nearly as attractive as T-bills on an after-tax basis for longer-term investors
- T-bills are issued at a discount — you pay LESS than face value on day one, receive your interest immediately, and get full face value at maturity. Seeing a smaller debit from your account on day one is correct, not an error
- You CAN sell T-bills before maturity through the secondary market — but the price depends on prevailing interest rates at the time of sale
- Yields are trending gently downward from 2025 peaks — if you want to lock in current rates, the 364-day tenor is strategically best to do so now before further compression
- Fake T-bill schemes promise 20–30% monthly returns — real T-bills yield 14–16% annually. Anyone offering monthly returns on "T-bills" is running a fraud

❓ Frequently Asked Questions
What is the minimum amount to invest in Nigerian Treasury Bills in 2026?
There are three minimum amounts depending on your access channel: ₦10,000 through investment apps like Bamboo; ₦100,000 through most commercial banks (GTBank, Zenith, Access, Stanbic IBTC) in secondary market pools; and ₦50,001,000 for direct CBN primary market participation. Most Nigerian retail investors use the bank secondary market pool route at ₦100,000 minimum. 📎 Source: CBN April 2026 auction notice; Stanbic IBTC T-bill page; moneyx.ng April 2026.
Is T-bill interest still tax-free in 2026?
No. From January 1, 2026, T-bill interest is now subject to a 10 percent Withholding Tax (WHT) deducted at source by your bank or broker. The frequently repeated claim that T-bill interest is tax-free applied to the period before the Nigeria Tax Act 2025 enforcement. FGN Bonds (long-term government bonds) remain fully tax-exempt under Section 163(1)(n) of the same Act. 📎 Source: NRS public notice, October 2025; smartsmssolutions.com investing after tax, January 2026; Nairametrics November 2025.
What are the current Nigerian T-bill interest rates in 2026?
At the most recent CBN primary market auction held April 8, 2026, stop rates were: 91-day bill at 15.95 percent, 182-day bill at 16.19 percent, and 364-day bill at 16.20 percent. These are gross rates before the 10 percent WHT. Net yields after WHT are approximately 14.36 percent, 14.57 percent, and 14.58 percent respectively. Rates have been gently declining from 2025 peaks and analysts forecast 15.5 to 17 percent range through mid-2026. 📎 Source: Nairametrics CBN auction report, April 11, 2026.
How do T-bills work in Nigeria — how is interest paid?
T-bills are issued at a discount. You do not receive interest at the end — you receive it on day one as a reduction in what you pay. Example: investing ₦100,000 face value at 16.20 percent for 364 days means your account is debited approximately ₦85,420 (not ₦100,000). The ₦14,580 difference is your net interest, received immediately. At maturity after 364 days, your account is credited ₦100,000 (the full face value). 📎 Source: CBN/DMO T-bill mechanism; Stanbic IBTC T-bill FAQ; moneyx.ng April 2026.
Can I buy Nigerian T-bills online without visiting a bank branch?
Yes, through most major bank internet banking portals. Stanbic IBTC has a dedicated online T-bill portal. GTBank, Zenith, and Access Bank offer T-bill investments through their internet banking platforms under Investments or Treasury Bills sections. You can also buy through investment apps like Bamboo and Zedcrest Wealth entirely online. Verify your specific bank's online T-bill availability by checking their website or calling the treasury desk. 📎 Source: Stanbic IBTC official T-bill portal description; moneyx.ng April 2026.
What happens if I need my money before the T-bill matures?
You can sell your T-bill in the secondary market before maturity. The price you receive depends on prevailing market interest rates at the time of sale. If rates have risen since you bought, your T-bill's price in the secondary market will be lower than what you paid — meaning you may receive slightly less than your purchase price. If rates have fallen, you may receive slightly more. To avoid this uncertainty, choose a tenor that matches when you actually need the money. The secondary market operates Monday to Friday, 10am–4pm. 📎 Source: Afrinvest T-bill guide; Stanbic IBTC T-bill FAQ.
How often does the CBN hold T-bill auctions?
The CBN holds T-bill primary market auctions every two weeks, typically on Wednesdays, with settlement on Thursdays. The April 2026 auction was held April 22–23, 2026. Issuance calendars are published quarterly on the DMO website at dmo.gov.ng. Secondary market trading is available every weekday from 10am to 4pm through authorized dealers including banks and stockbrokers. 📎 Source: CBN April 2026 auction invitation; DMO T-bill issuance calendar.
How do I calculate what my T-bill will actually earn after the 2026 tax?
Use this formula: Gross Interest = Face Value × (Discount Rate × Days ÷ 365). Net Interest = Gross Interest × 0.90 (after 10 percent WHT). Amount you pay on Day 1 = Face Value minus Net Interest. Example: ₦500,000 face value at 16.20 percent for 364 days = ₦81,000 gross interest, ₦72,900 net after WHT. You pay ₦427,100 on day one and receive ₦500,000 at maturity. You can also use TreasuryBillsCalculator.com.ng to model different scenarios. 📎 Source: CBN/DMO T-bill mechanism; NRS WHT rate October 2025.
Are Nigerian T-bills safe? What protects my money?
T-bills are considered the safest naira-denominated investment in Nigeria. They are issued by the CBN on behalf of the Federal Government and backed by the full faith and credit of the FGN. Under Nigerian law, if the government cannot pay, the CBN has authority to print naira to settle all T-bill investors. There is no default risk. The only risks are inflation risk (your return is fixed; if inflation exceeds your yield, you lose purchasing power) and interest rate risk if you sell before maturity. Principal loss is not possible if you hold to maturity. 📎 Source: DMO T-bill documentation; Stanbic IBTC T-bill page; moneyx.ng April 2026.
What is the difference between a T-bill and an FGN Bond in 2026?
T-bills are short-term (91, 182, or 364 days) and now subject to 10 percent WHT on interest. FGN Bonds are long-term (2–30 years) and remain completely tax-exempt under the Nigeria Tax Act 2025. At current rates, a 15 percent FGN Bond (tax-free) now competes directly with a 16.20 percent T-bill (approximately 14.58 percent net after WHT). For investors who don't need liquidity within 12 months, FGN Bonds deserve comparison. The DMO's FGN Savings Bonds start from just ₦1,000 minimum. 📎 Source: Nairametrics November 2025; DMO FGN Bonds page; smartsmssolutions.com January 2026.
Can I invest in T-bills through Cowrywise, Bamboo or PiggyVest?
Bamboo offers T-bill access from ₦10,000. Zedcrest Wealth offers T-bills from ₦100,000. Cowrywise offers access to T-bill-equivalent instruments — check their current product menu for specific availability and minimums. PiggyVest's investment products vary; check the app directly for current T-bill options. All these platforms aggregate user funds to meet the CBN minimum and allocate returns proportionally. Always verify that any investment app is SEC-Nigeria regulated before committing funds. 📎 Source: moneyx.ng April 2026; Zedcrest Wealth blog February 2025.
Does the bank keep any of my T-bill interest as a fee?
Yes. When a bank pools your funds with other customers to participate in the T-bill auction, they typically charge a small fee or retain a spread between the auction stop rate and what they pass to you. The rate you receive through a bank secondary market pool is typically slightly below the CBN auction stop rate. This is the cost of the pooling service. Investment apps similarly retain a fee from the platform's overall T-bill position. For the best rates closest to the CBN stop rate, use a licensed stockbroker with direct primary market access. 📎 Source: Cowrywise T-bill blog; moneyx.ng April 2026.
How do I renew or reinvest my T-bill when it matures?
T-bills are NOT automatically reinvested at maturity. When your T-bill matures, the face value is credited to your account. If you want to reinvest, you need to instruct your bank or broker before the maturity date. Set a calendar reminder 5 days before your maturity date. Contact your bank's treasury desk or use the internet banking portal to place a new T-bill instruction. Timing matters — primary market auctions only occur every two weeks, so if you miss the auction date after maturity your funds will sit idle until the next one.
Can I use T-bills as collateral for a bank loan?
Yes. T-bills are accepted as collateral by all Nigerian commercial banks. This is one of the advantages that makes them more flexible than savings account deposits for investors who may occasionally need access to credit. The collateral value is typically a percentage of the face value. Contact your bank's credit or treasury desk for specific terms on T-bill collateral borrowing — the exact percentage and terms vary by institution. 📎 Source: Afrinvest T-bill documentation; First Bank T-bill page.
What is the difference between competitive and non-competitive bids at CBN auctions?
A competitive bid means you specify the exact interest rate you want. If your requested rate exceeds the CBN's stop rate, your bid is rejected. A non-competitive bid means you accept whatever rate the CBN sets (the stop rate). For most retail investors investing through banks or brokers, you typically submit non-competitive bids — your bank enters non-competitive bids on your behalf at the auction stop rate. Competitive bidding is mainly relevant for large institutional investors who have strong views on where rates should clear. 📎 Source: CSL Stockbrokers T-bill guide October 2024; Afrinvest T-bill documentation.

Chinedu in Port Harcourt had ₦350,000 ready to invest. He was turned away with the wrong information and left that money earning almost nothing for months. His story is not unique — it plays out across Nigeria every day because the information gap on T-bill access is real and the consequences are measurable naira. If reading this article means one person with ₦100,000 logs into their internet banking tonight and places their first T-bill instruction instead of leaving money idle — that gap closes. I wrote this so that happens.
