Rand on firmer ground, helped by hawkish Reserve Bank comments
In a speech to investors in New York, Mminele said the Reserve Bank was aware of the inflationary effects of the rand's recent fall and was prepared to act to protect the currency's value.
At 1450 GMT, the rand was at 11.05 versus the dollar, not far off its previous close, and after earlier scaling a three-week high of 10.9630.
"Selling interest remains prevalent on the dollar-rand with a break of the key psychological 11.0000 handle," Tradition Analytics said on a note.
"A sustained break below the 10.9730 handle will target 10.9080."
Government debt edged higher, with the yield for the benchmark bond due in 2026 falling 5.5 basis points to 8.095 percent.
The rand has rallied more than 3 percent against the dollar this week, helped by the appointment of Kganyago which assured markets that the Reserve Bank would remain independent and continue to pursue transparent monetary policy.
