What this means for ZAR 100,000
Worked from the published rate · information, not advice
ZAR 5,175 in 6 months on the 182-day bill
Put ZAR 100,000 into the 182-day bill at this auction and you get back ZAR 105,175 after 6 months: ZAR 5,175 in interest before any withholding tax, about ZAR 863 a month.
That is ZAR 10 more than the same money would have earned at the previous auction.
For shorter money: ZAR 2,735 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.
