What is unfolding between Australia’s mining giants and Beijing is not a simple trade dispute. It is a quiet war over who sets the rules of one of the world’s most economically important commodities, and in which currency.

Iron ore underpins almost all modern industrial economies; it is the raw material from which steel is forged, and China remains its dominant consumer. For decades, Australian producers such as BHP and Rio Tinto have supplied much of that demand under pricing arrangements pegged to international indices and denominated in US dollars. Beijing now wants to rewrite that script.

At the heart of the confrontation lies a fundamental question of pricing sovereignty. Australia’s mining giants have long preferred the predictability of index-based, dollar-denominated contracts, which anchor their revenues and appeal to global investors.

China, however, views this system as a relic of Western control, and an arrangement that subjects its own vast steel sector to the volatility of spot markets - and the hitherto unchallenged supremacy of the dollar.

This uneasy balance began to tilt over the past decade, however, as mining firm shifted from long-term contracts to shorter, spot-linked agreements. In doing so, they captured higher margins during commodity booms but left Chinese buyers more exposed to swings in price.

Beijing’s response was, as ever, structural. In 2022, it established the China Mineral Resources Group (CMRG), a state-backed entity tasked with consolidating iron-ore imports and negotiating on behalf of the nation’s steel mills. In effect, China created a buyers’ cartel to counter the market power of Australia.

The tension has now reached a peak, and as of October 2025, more and more reports are surfacing that point to Beijing instructing steel mills and traders to pause purchases of BHP ore amid a deadlock over pricing terms.

At issue is BHP’s own insistence on maintaining US dollar-denominated contracts and Beijing’s demand for greater use of yuan settlement - a move that would align the commodity trade more closely with China’s own financial system, but one that will work towards the increased undermining of all things dollar denominated.

The apparent suspension of some imports was a clear signal that Beijing is willing to weaponise its purchasing power to both force a shift in market norms, and also open another front on its anti-dollar campaign of recent months.

Canberra, caught between commercial interest and geopolitical risk as well as close links to Washington, has been drawn into the standoff. Australian Prime Minister Anthony Albanese urged China to resume normal trade, attempting to call President Xi Jinping back to the negotiating table by stressing the need for stability in the sector.

For now though, China is having none of it.

The reality of the situation is that both sides have leverage, albeit with China in a slightly better position.

Australia’s miners enjoy the world’s lowest production costs and a product quality that Chinese mills struggle to replace at short notice. China, meanwhile, controls demand and as it so often does in times of stand-off, is developing alternative supply chains, most notably through the Simandou project in Guinea, West Africa.

Behind the economics though lies the all-important deeper face-off - Beijing’s push for yuan-based commodity settlement.

In pushing for Australia to use the yuan, China is looking to exert its own dominance on another industry as part of its broader efforts to erode dollar dominance and to set benchmarks that reflect its own market weight.

For Canberra, the stakes are equally existential: iron ore is Australia’s single largest export with, according to economics and geopolitics commentator Arnaud Bertrand in a post on X, “5% of Australia’s GDP depend(ing) on iron ore exports to China.” Bertrand adds that Australia “exports 85% of their iron to the country” and “as for China, 60% of their iron ore imports come from Australia.” As such, on paper at least, neither side can afford a full rupture, but neither seems ready to yet concede ground.

What follows therefore, may be a messy compromise at best but it is more than likely to be one in which China comes out on top in the form of partial yuan settlement here, index adjustments there.

Globally financial and sector analysts are watching closely, however, as this struggle is not just about contracts or currency; it is about who defines the architecture of global trade in an era when economic influence and political intent are increasingly inseparable.

Whether the next benchmark is priced in dollars or yuan will signal more than market preference. It will reveal whose rules the world’s raw materials will obey.
