Over the past year the 364-day rate has ranged from 3.60% to 7.18%.

What this means for ZAR 100,000
Worked from the published rate · information, not advice
ZAR 4,220 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 104,220 after 12 months: ZAR 4,220 in interest before any withholding tax, about ZAR 352 a month.
That is ZAR 90 more than the same money would have earned at the previous auction.
For shorter money: ZAR 1,970 on the 182-day bill (6 months), ZAR 938 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.
