How to Buy Treasury Bills in Ghana (2026)

The Treasury bill is Ghana's default savings instrument — lending to government for 91, 182 or 364 days, bought through your bank or a licensed investment platform. This guide covers how buying actually works, what it costs to get out early, how the interest is taxed, and how a T-bill stacks up against a fixed deposit or a savings account. For the current return, always work from the latest Bank of Ghana weekly auction result — never a rate quoted in an old article, and 2026 is the year that lesson bites hardest.

What you're buying

A Treasury bill is a short-term government debt instrument sold at a discount: you pay less than the face value today and receive the full face value at maturity — the difference is your return. The tenors are 91, 182 and 364 days. Rates are set at the weekly primary auction run by the Bank of Ghana on behalf of the Treasury, so the yield moves every week. Because it is a direct obligation of the Government of Ghana, the T-bill is the reference point every other cedi rate should be measured against.

Why the 2026 rate collapse matters to you

Treasury bill yields do not sit still, and 2026 has been a dramatic demonstration. The 91-day bill cleared in double digits in January 2026, and by the second and third quarters was printing in the mid-single digits as disinflation and heavy demand at auction pushed rates down hard. Whatever the number is on the day you read this, two consequences follow:

• Any rate in an article is stale. Including this one. Work from the auction.
• Rollover is no longer automatic value. If you set up a rolling 91-day ladder at 11% and stopped looking, you may now be rolling into something far lower. Re-check the yield at every maturity and compare it against a fixed deposit or a money market fund before you reinvest.

Falling nominal rates also change the real return question: what matters is the yield minus inflation, not the yield alone. See protecting your money from cedi depreciation.

Where to buy

1. Your bank. Most licensed banks sell T-bills over the counter and through their apps — GCB, Ecobank, Absa, Stanbic, CalBank, Fidelity and others. The bank places your bid at the auction and holds the bill for you in the Central Securities Depository.
2. Licensed investment platforms and primary dealers. SEC-licensed firms and primary dealers also sell T-bills, often with a slicker app and automatic rollover. Confirm the firm holds a current Securities and Exchange Commission (Ghana) licence before you fund an account — see how to avoid investment scams.
3. Rollover. At maturity you can take the cash or instruct reinvestment into the next auction. Set this deliberately — decide whether you are rolling over or cashing out, rather than letting a default do it for you.

The practical mechanics

• The minimum is low. The official minimum at auction is around GH¢100, though individual banks and platforms often set a higher practical minimum (commonly a few hundred cedis) to make the paperwork worthwhile. It is a mass-market product, not a wealth-only one — confirm the minimum with your chosen bank.
• You'll need an account with the selling bank or platform and your Ghana Card for KYC. Since 1 July 2022 the Ghana Card is the sole accepted identification at Bank of Ghana–licensed institutions.
• Bids close before the auction. Banks cut off orders a day or more ahead of the Friday auction, so money handed over on a Thursday may sit until the following week's bill. Ask for the cut-off if timing matters.
• Early exit. You can usually rediscount (sell the bill back) before maturity, but at a cost to your return — you take whatever the secondary price is on the day. Treat a T-bill as money you can lock away for the full tenor, and use shorter tenors if you might need the cash sooner.
• Tax. Interest paid to an individual on government securities, T-bills included, is exempt from tax under section 7 of the Income Tax Act, 2015 (Act 896) as amended. That exemption is a real part of the return — a taxed 8% deposit does not beat an untaxed 8% bill. It has periodically been debated as a revenue measure, so confirm the position with the Ghana Revenue Authority or your bank if you are committing a large sum. Companies are taxed differently.

T-bill vs fixed deposit vs savings account vs money market fund

• The T-bill is government risk — the cleanest, most direct option, tax-free for individuals, and the benchmark for everything else.
• A fixed deposit is bank risk, insured by the Ghana Deposit Protection Corporation only up to GH¢6,250 at a bank (GH¢1,250 at an SDI). A fixed deposit sometimes pays above the T-bill to attract funds — if one pays much more, ask why before chasing it, and remember deposit interest is taxed differently from bill interest.
• A money market fund holds a basket of short-term instruments, gives you faster access and professional management, and charges a fee for it — see money market funds explained.
• A savings account pays the least but stays liquid.

The honest comparison is always the net rate for the same lock-up period. Use the savings calculator to project what a given rate turns into, and compare savings and fixed-deposit accounts side by side.

Building a ladder

If you want both yield and access, split the money across tenors: buy 91-, 182- and 364-day bills so something matures every few months. You keep rolling whatever you do not need, and you are never forced to rediscount at a bad price to raise cash. It is the single most useful thing a Ghanaian saver can do with a lump sum, and it costs nothing to set up.

Frequently asked questions

Can I lose money on a Treasury bill? Held to maturity, you receive the face value — the real risks are the cost of selling early and inflation eating your real return. Ghana's 2023 domestic debt exchange restructured government bonds, not Treasury bills; bills continued to be issued and repaid throughout. As always, check current conditions before committing a large sum.

Is T-bill interest taxed in Ghana? Not for individuals — interest on government securities paid to an individual is exempt under section 7 of Act 896 as amended. Confirm with the GRA before relying on it for a large sum, and note that companies are treated differently.

How do I know the current rate? The Bank of Ghana publishes each auction's results weekly. Any rate not tied to a recent auction date is stale — use the latest published figure.

What is the minimum investment? Around GH¢100 at auction, though banks and platforms often set a higher practical minimum. Ask before you go in.

Bills or a fixed deposit? Compare the dated rates for the same tenor after tax, and remember whose risk you are holding: government (the bill) versus a bank (the deposit, insured only up to the GDPC limit).
