Dollar volatility returns in early September, lifting EM FX sensitivity including the South African rand

On Sept. 1, 2026 markets showed renewed dollar volatility and episodes of dollar weakness that revived carry flows and FX sensitivity across emerging markets. That move benefited higher-beta currencies and increased FX/term-premium uncertainty for EM credits, with the South African rand singled out in market reports.

Dollar volatility can amplify flow reversals: weaker USD episodes encourage carry-funded flows into higher-yielding EM assets, while subsequent dollar strength can reverse those flows and widen EM spread and local-currency volatility. For African exposures such as ZAR-denominated assets and USD hard-currency sovereigns, this means conditional pressure on local yields and funding costs if global risk sentiment shifts back toward USD demand.
