Iron ore prices collapsed this year as the biggest miners committed market vandalism by overproducing, according to Fortescue Metals Group Ltd. Rio Tinto Group fired a salvo in response, saying the analysis is overblown.
“The logic that you keep expanding just because you can squeeze an extra ton out of your machines, applies well to mining juniors,” Chairman Andrew Forrest said in a commentary on Monday as the company reported a slump in full-year profit. But it “is market vandalism and self-harm when industry leaders do it,” he said, without identifying any companies.
Iron ore sank last month to the lowest in at least six years as Rio Tinto and BHP Billiton Ltd. in Australia and Brazil’s Vale SA boosted cheap supply, betting higher volumes would offset lower prices. Fortescue will hold volumes steady this year, although it was ready to expand if demand revived, according to Forrest. Rio said Monday that Forrest’s remarks about the market were inconsistent, while BHP declined to comment.
“Iron ore is inelastic in demand,” Forrest said using a term that suggests consumption doesn’t change with price.
Once users’ demand has been met, “any further product offering will see the price collapse. We have seen that this year.”
