The rate shown is the average rate at which bills are allotted in the weekly auction.
Over the past year the 364-day rate has ranged from 6.49% to 7.54%.

What this means for ZAR 100,000
Worked from the published rate · information, not advice
ZAR 7,530 in 12 months on the 364-day bill
Put ZAR 100,000 into the 364-day bill at this auction and you get back ZAR 107,530 after 12 months: ZAR 7,530 in interest before any withholding tax, about ZAR 628 a month.
That is ZAR 10 less than the same money would have earned at the previous auction.
For shorter money: ZAR 3,735 on the 182-day bill (6 months), ZAR 1,785 on the 91-day bill (3 months).
The government pays the full amount at maturity; the risk is South Africa’s government not paying, and the money is locked until then.
