The rand has weakened this week along with other emerging-market currencies as the dollar strengthened on rising US Treasury yields. Weakness was amplified by a soft Quarterly Employment Statistics report from Statistics South Africa, which showed total employment falling 0.9% quarter on quarter.
Global risk-off drivers cited include Evergrande, the US debt ceiling and a hawkish Federal Reserve.
A weaker rand raises the local-currency cost of dollar-priced feed ingredients such as soybean meal and corn imports. The currency move is driven mainly by global risk sentiment and dollar strength rather than by grain fundamentals.
