The four biggest iron-ore suppliers accounted for 71% of all iron-ore shipments in 2014, and they aren’t slowing down
SYDNEY—Big Mining is tightening its grip on the iron-ore market.
As industry giants such as Rio Tinto PLC and BHP Billiton Ltd. dig up ever more of the steelmaking ingredient for export, the resulting supply glut has caused prices to slump. But the majors’ tactics are helping them squeeze out smaller rivals, increasing their oligopoly’s share of global trade in the ore.
The world’s four biggest iron-ore suppliers—Rio and BHP along with Brazil’s Vale SA and Australia’s Fortescue Metals Group Ltd.—accounted for 71% of the world’s iron-ore shipments in 2014, up from an average of 65% from 2009-13, according to Citi estimates. The bank now reckons that market share for the four could rise to 80% by 2018.
There is no sign the majors are ready to pull back.
