At the Treasury bill auction dated 17 August 2026, the Bank of Ghana cleared the 91-day bill at 5.47% (down 16 basis points), the 182-day bill at 7.27% (down 25 basis points) and the 364-day bill at 12.50% (down 49 basis points). The rate shown is the weighted average interest-rate equivalent.
Bids totalled GHS 11.3bn and GHS 4.9bn was accepted, 43% of what was bid.
Over the past year the 364-day rate has ranged from 9.35% to 13.09%.
A year earlier the 364-day bill cleared at 13.10%, so the government is paying 60 basis points less than twelve months ago.
What this means for GHS 10,000
Worked from the published rate · information, not advice
GHS 1,250 in 12 months on the 364-day bill
Put GHS 10,000 into the 364-day bill at this auction and you get back GHS 11,250 after 12 months: GHS 1,250 in interest before any withholding tax, about GHS 104 a month.
That is GHS 49 less than the same money would have earned at the previous auction.
For shorter money: GHS 364 on the 182-day bill (6 months), GHS 137 on the 91-day bill (3 months).
The government pays the full amount at maturity; the risk is Ghana’s government not paying, and the money is locked until then.
