Johannesburg - South Africa's rand weakened further to a one-month low on Thursday, weighed down by lingering uncertainty over whether the finance minister faces arrest.
By 15h00 GMT the rand was 0.7 percent weaker at 14.2550 per dollar compared with the close of 14.1575 overnight.
The rand fell as much as 4 percent when it emerged on Tuesday police had summoned Finance Minister Pravin Gordhan to answer questions over the lawfulness of a spy unit in the revenue service.
The unit regained some ground in early trade, briefly touching 13.9565, before resuming its slide despite President Jacob Zuma saying he supported Gordhan, although would not be able to intervene in the investigation.
“The market, seemingly, is rating the latest political news as similar to that of February and May, the dates when the Hawks probe became public and when Minister Gordhan responded,” Rand Merchant Bank currency strategist John Cairns said in a note.
