In April, BHP ended a seven-month standoff with its largest customer. China Mineral Resources Group, the state-backed entity that consolidates iron ore purchases for Chinese steel mills, had partially shut the Australian miner out of China since September.

As the price of readmission, Chinese media reported, BHP agreed to rewrite the pricing formula for Jimblebar fines, a product line that accounts for roughly a quarter of its output from the Pilbara region of Western Australia. For the first time, a yuan-denominated Chinese port index will anchor 51 percent of the formula, with the traditional S&P Global Platts benchmark removed entirely. The contract may still convert that reference price into dollars, but the shift is significant; Beijing has inserted its own benchmark into the machinery of global commodity pricing.

No major iron ore producer had previously allowed a yuan-denominated Chinese benchmark to anchor most of a long-term pricing formula. In that regard, the deal may matter more for China’s currency ambitions than the payments statistics that usually frame the debate.

Discussion of yuan internationalization tends to fixate on settlement: that is, on the payment shares, SWIFT volumes, and the tally of swap lines. By those measures, progress looks underwhelming. In recent months, the yuan’s share of SWIFT payments has hovered around 3 percent, though partly because more yuan traffic now routes through China’s own clearing system.

Settlement, however, is the most visible and least durable of currency’s functions. A trading partner that settles in yuan this year can revert to dollars the next. Pricing is different. Once a benchmark is embedded in long-term contracts, hedging chains, and corporate accounting, it calcifies. Oil has been priced in dollars since the 1970s, outlasting every prediction of the petrodollar’s demise and a turnover of major buyers and sellers.

Pricing also unlocks settlement. So long as a cargo is priced in dollars, a seller accepting yuan takes on currency risk between invoice and conversion. Price the cargo in yuan, and this mismatch disappears, along with a major commercial disincentive. The big four iron ore majors have settled occasional cargoes in yuan since 2017, but with contracts still priced off dollar indexes, the experiments stayed experiments. The barrier sat in the pricing formula, not the payment rails.

Beijing has internalized the lesson and is applying leverage where it has some. China buys roughly three-quarters of seaborne iron ore and accounts for about half the world’s base metals consumption. CMRG was created in 2022 precisely to convert that demand into bargaining power, ending an era in which hundreds of Chinese mills bid against one another. The strategy appears to be working. Rio Tinto and Fortescue had already dropped Platts from their CMRG term contracts in December, shifting to Argus and Mysteel indexes. BHP’s concession goes further, anchoring the majority of the formula to the yuan for the first time.

Inside China, influential voices now want to extend the model. Zhang Ming, a leading scholar at the Chinese Academy of Social Sciences, argued that Chinese importers should negotiate as a bloc across bulk commodities and press for yuan pricing as a standard term. Hong Kong Financial Secretary Paul Chan, pitching London Metal Exchange traders in May, made the case for more yuan-denominated commodity products to help traders manage currency risk.

Yuan-denominated financing helps close the loop. Last August, Fortescue took a record 14.2 billion yuan syndicated loan from Chinese banks at 3.8 percent – well below the roughly 6 percent it paid on comparable dollar facilities – repayable out of yuan revenues from iron ore sales to China. A miner paid in yuan has a reason to borrow in yuan, and a miner indebted in yuan has a reason to price in it.

None of this means the dollar’s commodity dominance is ending. Iron ore is uniquely fruitful terrain, involving a single dominant buyer, physical delivery into Chinese ports, and credible indexes built on observable port transactions. Oil and LNG feature diversified buyers, entrenched benchmarks, and Gulf producers whose currencies are pegged to the dollar. Sellers will accept yuan pricing at scale only if they can hedge it, which requires deep yuan derivatives markets and offshore liquidity that remain thin next to dollar equivalents. And China’s capital controls cap the endgame: pricing power can win trade settlement, but it cannot by itself make the yuan a currency the world wants to hold.

The right way to track this campaign is therefore not the monthly settlement statistics but the contract terms. Markets should watch whether yuan-linked formulas surface in copper, soybean, or LNG contracts, and whether Chinese port indexes become hedgeable offshore. Benchmarks shift quietly, contract by contract, and the dollar’s grip on commodity pricing took decades to set. But it is in pricing formulas – not just payment shares – that the yuan’s future is being negotiated.
