The rand retreated on Tuesday as a resurgent dollar pushed back and wiped away early demand for risk currencies while turning up technical pressure on the local unit.
The bourse gained ground lifted higher by mining companies.
At 1500 GMT the rand had weakened 0.35% to 13.03 per dollar, sinking to its softest level in nearly a week despite early demand that lifted the unit to session-high of 12.87 before the greenback’s rebound kicked-in.
The dollar index extended gains slightly on the day after recording its largest gain this month on Monday, with receding worries about North Korea and Hurricane Irma soothing sentiment.
The latest twist in the political spat between the central bank and Public Protector had yet to affect trade in the rand, traders said, with technical considerations the main focus.
“Demand from local corporates and offshore investors was fairly robust this morning even after the Sarb’s comments on the Protector’s report. The rand’s move was about the dollar’s comeback versus EM currencies and commodities,” senior trader at Standard Bank Oliver Alwar said.
The Reserve Bank on Tuesday accused the anti-graft watchdog of glaring omissions and procedural unfairness in her report that recommended the bank’s mandate be changed to focus on growth rather than currency and price stability.
“Technically the rand’s also had a downside failure after last Friday’s indecisive close, resulting in the reversal we’ve seen over the last few days,” Alwar added
The rand managed gains of around 5% in the last month, breaking through crucial technical levels, but has lost momentum in recent sessions and is expected to see further short-selling.
