₵20,000 at every tenor
| Tenor | Rate | Interest | At maturity | Real return |
|---|---|---|---|---|
| 91-daymatures 30 November 2026 | 4.9460% | ₵246.62 | ₵20,246.62 | -0.4pp |
| 182-daymatures 1 March 2027 | 6.8587% | ₵683.99 | ₵20,683.99 | +1.6pp |

The arithmetic, shown in full for the 91-day: ₵20,000 × 0.049460 × 91 ÷ 365 = ₵246.62. Ghana uses an actual/365 day count, which is why the 364-day earns 364/365 of its annual rate rather than the full year.
Roll it or lock it — in cedis
| Roll the 91-day four times | +5.02% | ₵1,004.89 |
| Lock the 364-day once | +10.75% | ₵2,149.65 |
A difference of ₵1,144.77 on ₵20,000 — but this assumes rates stay where they are, and they won't. It shows the tradeoff at today's curve, not a prediction, and it is not a recommendation of either.
Where the interest starts covering real bills
At ₵20,000 the interest stops being a rounding error and starts paying for things. The 91-day yields ₵246.62 a quarter, and the most grounded way we can express that is against our own price data: the Makola food basket we track weekly costs about ₵480, so a quarter's interest on ₵20,000 is roughly 0.5 of those baskets. That is a real, checkable comparison rather than a percentage — the same shopping we price every week, funded by the interest rather than the capital. At this level the tenor choice also starts to matter in cash terms rather than basis points, which is what the ladder table above is showing you.
The basket behind that comparison is on market prices.
