The Paradox of a Weakening Economy Supporting the Rand

Key points

• South Africa’s trade dynamics continue to provide crucial support for the ZAR, although the drivers of this support reveal underlying economic vulnerabilities that cannot be ignored.
• Weak private sector credit extension maintains the trade surplus by suppressing import demand, but early signs of credit growth acceleration suggest this dynamic may shift as rate cuts take effect.
• The trade surplus substantially cushions the current account deficit, limiting external financing requirements and providing a buffer against currency volatility even as economic recovery potentially erodes this support.
• Terms of trade remain highly favourable, driven primarily by elevated gold prices, although logistical failures continue to prevent South Africa from fully capitalising on this advantage.

Baseline view

South Africa’s trade account continues to underpin ZAR resilience, although sustainability faces mounting challenges. Whilst the trade surplus narrowed to R20.3bn in July and external headwinds intensify with looming US tariffs, the combination of subdued credit growth, favourable terms of trade, and manageable external financing needs maintains a constructive backdrop for the currency. Any meaningful economic recovery would paradoxically erode these supportive dynamics.
