South Africa's Rand Shows Its Mettle as Iron-Ore Prices Surge

(Bloomberg) -- If you are searching for clues on how the rand will move next, watch the iron-ore price.

The South African currency is closely tracking the fortunes of the raw material, with the 40-day correlation in daily moves climbing to 0.91 this week, the highest since January 2018. A value of 1 would indicate they moved in lock step.

South Africa's Rand Shows Its Mettle as Iron-Ore Prices Surge

The rand has strengthened 2.5 percent against the dollar since Jan. 25, when a fatal dam disaster at Vale SA’s Brumadinho mine in Brazil curbed iron-ore supplies, sending the price soaring.

About a quarter of the rand’s moves can be ascribed to iron ore prices, according to Standard Bank Group Ltd., with a one percent rise in the commodity equating to about a 0.5 percent gain for the currency. The mineral accounts for 12 percent of total South African mining production and close to 18 percent of base-mineral exports.

“We are in the top 10 ore-producing countries in the world,” Thanda Sithole, a Johannesburg-based economist at Standard Bank, said in a client note. “The rand therefore naturally has a correlation with iron-ore prices.”

Shares of Kumba Iron Ore Ltd., South Africa’s biggest producer, have jumped 18 percent since the dam collapse.
