At 5pm, the rand bid at R12.1149 to the dollar, 9.32c firmer than at the same time on Friday, and 0.49percent firmer than its New York close on Friday.
The ANC discussed last week removing President Jacob Zuma as head of state but no decision or date for his departure was agreed, secretary general Ace Magashule said yesterday.
There has been widespread speculation in local media that the ANC’s 80-member executive committee passed a resolution at the weekend calling for the removal of Zuma as South African president.
Any sign that Zuma could step down before his second presidential term ends in 2019 has tended to lift South African assets, including the rand.
The rand has rallied to a two-and-a-half year high since union leader-turned-businessman Cyril Ramaphosa won the ANC leadership on December18 as investors bet he would crack down on corruption and implement policy reforms.
The ANC’s electoral dominance means he will almost certainly be the country’s next president.
On Saturday a government committee headed by Ramaphosa appointed a new board at state-owned power utility Eskom to help tackle governance concerns.
“The financial markets have reacted very positively to these and related developments in the ANC, as have many of the disaffected voices who last year were clamouring for change in the ruling party,” said NKC African Economics analyst, Gary van Staden.
