What this means for ZAR 100,000
Worked from the published rate · information, not advice
ZAR 1,380 in 3 months on the 91-day bill
Put ZAR 100,000 into the 91-day bill at this auction and you get back ZAR 101,380 after 3 months: ZAR 1,380 in interest before any withholding tax, about ZAR 460 a month.
That is ZAR 5 less than the same money would have earned at the previous auction.
The government pays the full amount at maturity; the risk is South Africa’s government not paying, and the money is locked until then.
