Kumba Iron Ore warns of steep profit drop as rand strength bites

Kumba Iron Ore, Anglo American's South African iron ore unit, said on 21 July 2026 that headline earnings per share for the six months to 30 June were likely to fall between 39% and 43%. The company pointed to the rand's appreciation of about 11% against the US dollar over the period, combined with a marginally lower dollar-denominated average export price, as the main drags on earnings, even as sales volumes held up.

Kumba's realised free-on-board export iron ore price averaged $90 a wet metric tonne in the first half of 2026, only slightly below the $91 achieved in the same period of 2025, underlining that the earnings hit was driven overwhelmingly by the currency rather than by a collapsing commodity price.

A textbook case of rand-driven margin squeeze

Kumba's results were a clean illustration of a dynamic South African commodity exporters face repeatedly: because iron ore is priced and sold in dollars while a large share of costs, including wages, are paid in rand, a stronger currency mechanically compresses dollar-reported margins even when the underlying commodity price barely moves. The same 11% rand appreciation that squeezed Kumba's earnings would, all else equal, have been read as a broadly positive signal by economists tracking inflation or import costs, underscoring the very different lens through which currency moves are viewed inside and outside the mining sector.

Diversifying away from China

Kumba also confirmed a shift in its customer base, with sales to China falling to 53% of the total in the first half of 2026 from 58% previously, as the company redirected more volumes to Japan, South Korea and other Asian markets, which rose to 25% of sales from 21%, while Europe held steady at 21%. That diversification reflected weak Chinese steel production and a deliberate strategy to reduce dependence on a single, slowing market for South Africa's largest iron ore exporter.

Analysts covering the stock noted that Kumba's experience offered a cautionary template for other rand-earning, dollar-costed exporters across South African mining: even a commodity price that barely moved could still deliver a dramatic earnings miss purely on the back of currency strength driven by events, such as gold's rally, entirely unconnected to the company's own product.
