The weakness of the South African rand, which lost 0.74% against the US dollar to reach 17.0896 USD/ZAR, was not enough to boost mining exporters this week. Traditionally, a weaker rand boosts the profitability of mining companies whose costs are in ZAR and revenues in USD. However, the flare-up of geopolitical uncertainty following attacks on Iran created erratic volatility in commodity markets, disrupting this dynamic. Brent crude, although up +6.4% for the week at $106.6/barrel, experienced sharp fluctuations, while gold surprised by falling 1.1% to $4,549.3/ounce despite its usual safe-haven status.
