"Retail is vital to a consumption-driven economy such as South Africa and has been weighed down by the cost-of-living crisis," ETM Analytics said in a research note.
Retail sales have contracted in annual terms in every month since December 2022, with rolling power blackouts a contributing factor.
But an easing in the intensity of the power cuts in June may have provided some support to sales, ETM Analytics added.
