Let's do some money maths.

- A thread

We started from here.

And arrived at this conclusion:

If you invest $1m in Treasury bills you get the following amount MONTHLY while your $1m remains untouched with the Central Bank.

Kenya - Ks 857k
Nigeria - N3m
South Africa - 90k Rand
Zambia - 109k Kwacha
Ghana - 65k cedis

Here's the math.

For Nigeria:

$1m = N360m

Treasury bill rate = 10% per annum

Annual return = N360m x 10% = N36m

Monthly return = N36m/12

Monthly return = N3m or $8,333

For Kenya:

$1m = 103m Kenyan shillings

Treasury bill rate = 10% per annum

Annual return = Ks 103m x 10% = Ks 10.3m

Monthly return = Ks 10.3m/12

Monthly return = Ks 858,333 or $8,333

For South Africa:

$1m = R15.2

Treasury bill rate = 7% per annum

Annual return = R15.2m x 7% = R1.064m

Monthly return = R1.064m/12

Monthly return = R88,666 or $5,844

For Ghana:

$1m = GHC 5.45m

Treasury bill rate = 14% per annum

Annual return = GHC 5.45m x 14% = GHC 763,000

Monthly return = GHC 763,000/12

Monthly return = GHC 63,583 or $11,663.18

Caveats.

1. Tax rates differ by country. It will affect your actual return.
2. Ghana has the highest ROI, South Africa the lowest.
3. Lots of opportunities for arbitrage, if taxation is not prohibitive.
4. This is not financial advise. Please do your own due diligence.
