Building a Nigerian Treasury Bills Ladder for Steady Returns
Use Nigerian Treasury Bills — safely, in a laddered structure — for steady income and to preserve capital. Anti-hype: T-bills preserve, they do not build wealth; and they are no longer tax-free.

What you'll gain
A Treasury Bill is the safest naira instrument there is — but it preserves your money, it does not grow you rich, and it is no longer tax-free. Learn the honest, buildable way to use Nigerian T-bills — arranged into a ladder — for steady income and capital preservation, built from a source-graded 2026 research pass over the mechanics, the yield math, the ladder strategy, the tax and risk, and a dated scam museum. First, the reframe: a T-bill is a discount instrument — you pay LESS than face value and collect the full face at maturity, so the quoted “rate” actually UNDERSTATES your true return (a bill quoted at ~17% earns you ~21% on the cash you laid out). Second, the honesty centre: T-bills preserve capital and pay modest, steady income — for much of the last decade their after-inflation return was NEGATIVE, so the number that matters is the REAL return (yield minus inflation, and now minus tax), not the headline. Third, the flagship correction almost every older guide gets wrong: T-bills are NO LONGER tax-free — a 10% withholding tax has applied since 28 October 2025, for individuals and companies alike (though FGN bonds, including the FGN Savings Bond, stay exempt). You will learn how the CBN auction really works and how a retail investor actually buys (via a bank or an app, not the ₦50m-minimum primary auction); the discount-vs-true-yield formulas with a worked example; how to build and roll a three-rung ladder so a tranche matures every few months; the rollover mandate that is NOT automatic; the risk stack behind the word “safe”; how T-bills compare to savings, fixed deposits, money-market funds and the tax-exempt FGN Savings Bond; who a ladder is genuinely for; and how a business earns on idle cash without starving payroll. Two people build alongside you: Mr. Bello, a retiree who almost loses his gratuity to a “20%-a-month” scheme, and Amaka, who runs a small business and ladders both her company cash and her savings. A dated Scam Museum anchors the honesty — MMM, MBA Forex, CBEX — and the one-line filter no fraud survives: if the “guaranteed” return is far above the current T-bill rate, it is not a treasury bill, whatever they call it. Carry one line: preserve first, verify the real return, and never chase a rate a government bill cannot pay. Financial education, not personalised investment advice.
