Iron ore and the yuan: China's bid to break the dollar

THE CHINESE steel industry has spent decades paying for imported iron ore in American dollars. Now it wants to pay in yuan. The push, led by state-backed buyers and domestic mills, is not merely a reaction to volatile exchange rates or a tactical response to recent trade tensions. It is a coordinated attempt to wrest pricing power from global financial markets and anchor the world's largest bulk commodity trade to China's domestic economy.

China imports more than 75% of the world's seaborne iron ore. For years, its purchasing has been deeply fragmented, with thousands of mills and independent traders negotiating their own deals. This dispersion left Chinese buyers vulnerable to the collective bargaining tactics of the big four miners: BHP, Rio Tinto, Fortescue and Vale. In 2022, Beijing established the China Mineral Resources Group, a state-owned procurement vehicle capitalised with 20bn yuan ($3bn), to consolidate demand and coordinate buying. The push for yuan pricing is the logical, and inevitable, extension of this centralisation.

The structural problem is not just the currency; it is price discovery. Currently, iron ore is largely priced against dollar-denominated financial benchmarks, primarily futures on the Singapore Exchange and the IODEX index. Chinese steelmakers argue that this system allows global financial investors to inflate prices beyond what physical supply and demand warrant. By pricing iron ore in yuan, and specifically by linking it to "portside" trade (spot cargoes sold directly to mills at Chinese docks), buyers can ground prices in observable, high-frequency physical activity. The infrastructure for this regime is already in place: the Dalian Commodity Exchange yuan futures price hovers around 706 yuan a tonne, and a growing share of spot deals are settling against domestic indices rather than overseas ones. In short, China wants to stop paying a financial premium to Western traders and start paying for the actual rock in its own currency.

To be sure, the shift carries genuine risks for the sellers. Miners sell in a global market but incur most of their extraction and logistics costs in Australian dollars, Brazilian real or American dollars. A move to yuan settlements forces them to internalise currency risk. Hedging and cash-flow timing become significantly more complex when revenue is denominated in CNY and costs are elsewhere. Furthermore, the yuan is still a long way behind the dollar in global liquidity, accounting for about 4.1% of global payments in March 2025. If miners are forced to hold large yuan balances, they face treasury headaches and a lack of deep offshore markets to park the cash.

Yet China's leverage is structural, not just financial. With the recent ramp-up of the Simandou mine in Guinea, which will eventually add up to 120m tonnes of high-grade ore to the market, Beijing can credibly threaten to rotate supply away from uncooperative producers. It is precisely this kind of calibrated squeeze that led BHP to agree in late 2025 to settle 30% of its spot iron-ore sales to China in yuan. The mining giant calculated that the cost of doing business in yuan was lower than the cost of losing access to the Chinese market, a calculation that has since been echoed by other suppliers eager to secure offtake in a softening market. As RMB transactions in the sector climbed to 12% by early 2026, the trend line became impossible to ignore.

For investors and producers, the migration of iron-ore pricing onshore means higher basis risk-the divergence between the physical settlement price and the financial hedging price-and a permanent shift in where value is captured. Financial hedging on Singapore or London exchanges will become less effective as physical contracts drift toward the Argus/Mysteel average or domestic portside yuan indices. The resulting system will be more reflective of real cargo, but also more susceptible to Beijing's policy whims and its desire to keep input costs low for its domestic steelmakers.

The yuan-iron-ore trade is a masterclass in state capitalism. It uses sheer market scale to discipline suppliers, while quietly advancing the internationalisation of the renminbi. Dollar dominance in commodities is slowly but surely eroding, driven not by US weakness but by Chinese coordination. Miners who cling to the greenback and ignore the new pricing reality will find their bargaining position diminishing with every new yuan-denominated contract. The cost of doing business in China is no longer just about tariffs or quotas. It is about currency.
