At 5pm, the rand bid at R12.1173 to the dollar, slightly weaker than at the same time on Monday, eating into gains of around 1percent a day earlier after the ANC confirmed it was discussing whether to push for Zuma’s removal as head of state.
The rand has surged since Cyril Ramaphosa won the race to succeed Zuma as ANC leader last month, putting him in pole position to become the country’s next president.
Ramaphosa, currently deputy president, is leading South Africa’s delegation to the World Economic Forum in Davos this week and has pledged to fight corruption and woo foreign investment.
His allies in the ANC are pushing for him to take over from Zuma as state president in the coming weeks.
A currency trader at Rand Merchant Bank said the rand was likely to trade in tight ranges until Zuma’s fate became clearer. But a break below R12 to the dollar could trigger further rand gains, he said.
Government bonds were little changed, with the yield for the benchmark 2026 instrument at 8.35percent.
