Officials briefed on the matter described supply chains as a turning point that few analysts had penciled in even a quarter earlier, citing shifts in wage growth and a recalibration of expectations across Southern Africa.

Markets responded in measured fashion. Traders pointed to supply chains as the principal catalyst, though strategists at three large banks cautioned that the underlying dynamics in wage growth remain unsettled.

Behind the headline figures, a more nuanced picture is emerging. Practitioners closest to supply chains say the conversation has quietly turned toward wage growth, a shift that would have been unthinkable as recently as last winter.

Critics argue the response has been too cautious. Supporters counter that any move on supply chains must be weighed against the still-fragile recovery in wage growth, particularly across Southern Africa.

The longer arc is harder to read. For now, supply chains appears to be reshaping the calculus around wage growth, and few of the people interviewed for this piece expected that recalibration to reverse before year-end.
