If you've ever heard someone in Accra mention "T-bills" and nodded along without really knowing what they meant, you're not alone. A treasury bill is simply a short-term loan you give to the Government of Ghana — and in return, the government pays you back more than you lent, after a fixed period.
It's one of the simplest, safest ways to start investing, which is exactly why it's often the very first thing people buy once they've got a bit of savings together.
You don't need GH₵10,000 to start — many banks and mobile apps now let you buy your first bill with as little as GH₵100.
What is a treasury bill?
A treasury bill (or "T-bill") is a short-term government security — essentially an IOU from the Government of Ghana. You hand over an amount of money today, and the government promises to pay you a larger amount back on a fixed future date, called the maturity date.
The difference between what you pay and what you receive back is your return. There's no interest "paid out" along the way — you buy at a discount and collect the full face value at maturity.
How treasury bills work in Ghana
In Ghana, treasury bills are issued by the Bank of Ghana on behalf of the government, through a weekly auction. Most everyday investors don't bid in the auction directly — instead, you buy through a commercial bank, a licensed broker, or increasingly, a mobile app that pools smaller investors together.
- You choose a tenor (how long your money will be locked up) and an amount.
- Your bank or platform submits your order into that week's auction.
- Once the auction clears, you're told the rate you'll earn for that tenor.
- At maturity, the face value lands back in your account automatically.
Treasury bill tenors and rates
Treasury bills in Ghana are typically sold in three tenors. Longer tenors usually — though not always — pay a higher rate, since you're committing your money for longer.
| Tenor | Term | Illustrative rate |
|---|---|---|
| 91-day bill | ~3 months | ~26% |
| 182-day bill | ~6 months | ~27% |
| 364-day bill | ~12 months | ~28% |
These figures are illustrative only, to show how tenor and rate typically relate — actual rates change with every auction. Always check the current rate with your bank or the Bank of Ghana before buying.
How to buy your first treasury bill
Buying your first T-bill is more straightforward than most people expect:
- Open a savings or investment account with a commercial bank, or sign up on a licensed investment app.
- Ask specifically about treasury bills — some banks call this a "money market" or "fixed income" product.
- Decide your amount and tenor, then confirm the order before the week's auction closes.
- Keep the confirmation — you'll need it if you ever want to check your holding or withdraw early.
Risks and what to know
Treasury bills are widely considered one of the safest investments available in Ghana, since they're backed by the government rather than a private company. That doesn't mean they're risk-free.
In periods of high inflation, the return on a T-bill can lag behind rising prices — meaning your money grows in cedi terms but may still lose some real purchasing power. It's a safe place to start, not necessarily the only place to stay.
Key takeaways
- A treasury bill is a short-term loan to the Government of Ghana, bought at a discount and repaid at face value.
- Common tenors are 91, 182, and 364 days — longer tenors usually pay more.
- Many banks and apps now accept as little as GH₵100 to start.
- T-bills are low-risk, not no-risk — inflation can still erode real returns.
