What this means for ZAR 100,000
Worked from the published rate · information, not advice
ZAR 2,125 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 102,125 after 6 months: ZAR 2,125 in interest before any withholding tax, about ZAR 354 a month.
That is ZAR 5 less than the same money would have earned at the previous auction.
For shorter money: 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.
