Zuma, in power since 2009 and beset by corruption allegations, has been in a weakened position since Deputy President Ramaphosa replaced him as ANC leader in December. Ramaphosa has talked of a transition of power since he took over as leader of the ANC.
“The political drama in South Africa continues,” Commerzbank analysts said in a research note. “At present it looks as if the Zuma era is finally nearing its end, which would of course be good news for the rand.”
The rand has tended to strengthen on signs that Zuma could step down early.
