Iron Ore

The biggest bulk commodity on the ocean — and the raw feedstock of the entire steel age.

Iron ore is mining at civilizational scale: roughly 2.5 billion tonnes are extracted each year, and about 98% of it becomes steel — the material of buildings, bridges, ships, cars, and machines. The seaborne trade, dominated by a handful of giant producers shipping from Australia and Brazil to Asian blast furnaces, is the largest bulk commodity market on Earth. Unlike exchange-traded base metals, iron ore’s fortunes hang overwhelmingly on one buyer: China, which consumes well over two-thirds of seaborne supply.

Key Applications

Blast furnace steelmaking (sinter fines and lump)
Pellets for direct reduced iron (DRI) and green steel
Construction, infrastructure, and heavy machinery steel
Automotive and shipbuilding steel

Key Facts

Seaborne leaders: Australia, Brazil
Dominant buyer: China (>2/3 of seaborne)
Benchmark grade: 62% Fe fines
End market: ~98% into steel
New supply: Simandou (Guinea)

Market Dynamics

Prices key off the 62% Fe fines benchmark and swing with Chinese construction cycles, stimulus announcements, and steel mill margins. The market’s structure is an oligopoly of low-cost giants — Rio Tinto, BHP, Vale, and Fortescue — whose Pilbara and Carajás operations produce at costs far below marginal suppliers, giving the majors resilience through downturns that smaller producers cannot match. A structural shift is underway in quality: green steel routes (DRI-EAF) require much higher-grade ore, opening a widening premium between DRI-grade pellets and standard fines.

Supply Chain

The chain is logistics: mine, heavy-haul rail, dedicated port, capesize vessel, Asian discharge port, blast furnace. Australia’s Pilbara and Brazil’s Carajás dominate seaborne supply, with Guinea’s giant Simandou project — decades in the making — arriving as the first major new supply province in a generation. Scrap-based EAF steelmaking is iron ore’s long-run substitute: every tonne of recycled steel displaces about 1.6 tonnes of ore.

Outlook

Chinese steel demand has plateaued as its construction boom fades, and rising scrap availability plus Simandou tonnage point to a softer long-run balance for standard-grade ore. The growth story is quality, not quantity: DRI-grade pellets and high-purity ore for green steel command widening premiums as steelmakers decarbonize. India stands out as the next major demand engine.
