NKC African Economics analysts said in a note that news that Brian Molefe would return next week as CEO of power utility Eskom had hit the local currency.

Richemont's South African-listed shares fell 5.09 percent to 108.34 rand after the Swiss-listed luxury goods company posted a drop in full year profit.

"We have seen a little bit of weakness creeping into rand hedges, particularly Richemont. There was a miss on their results this morning and the market didn't take too kindly to that," said Independent Securities trader Ryan Woods.
