BHP Group, the world's largest miner, has ended a six-month standoff with Beijing by agreeing to incorporate a Chinese yuan-linked pricing index into its long-term iron ore contracts, marking the first time one of the four dominant global miners has formally accepted Chinese control over a component of commodity pricing. The deal, announced April 24, 2026, following intensive negotiations with state-backed China Mineral Resources Group (CMRG), covers BHP's flagship Jimblebar fines product through the end of the 2027 financial year.

The COREX Deal | 26% Yuan Weighting, 1.8% Vessel Rebate
The hybrid pricing model accepted by BHP uses the COREX 61% Portside Index, a Beijing-based benchmark that tracks the price of iron ore already sitting in Chinese ports, rather than the traditional seaborne indices such as Platts or Argus, which are settled in US dollars and reflect shipping prices at origin. The COREX index will carry a 26% weighting in the final price calculation for affected contracts, with the remaining 74% remaining tied to legacy dollar-denominated benchmarks.
BHP also agreed to provide a 1.8% rebate per vessel on these contracts, settling a long-running dispute that had seen certain BHP ore grades effectively excluded from Chinese port acceptance queues in early 2026. The rebate functions as a retroactive concession for shipments that faced delays or surcharges during the standoff period. CMRG has not commented on the terms of the dispute or the timeline of negotiations. BHP's statement described the arrangement as reflecting "a shared commitment to long-term supply stability."
The significance of the COREX concession lies in its precedent rather than its 26% weighting. Portside indices, which track ore priced in RMB at Chinese storage facilities, give Chinese buyers structural pricing leverage over seaborne suppliers because they measure a market that Beijing directly administers. A miner accepting even a minority COREX weighting validates the index's legitimacy as a global benchmark, which creates pressure on Rio Tinto and Vale to accept similar terms in their own contract renegotiations. Neither company has commented on whether it faces equivalent pressure from CMRG.
The Hormuz Toll Connection | IRGC Yuan Demands Are Reshaping Trade Finance
The BHP deal did not emerge in a vacuum. Since mid-March 2026, the Islamic Revolutionary Guard Corps has enforced a mandatory toll of approximately $1 per barrel on oil tankers transiting the Strait of Hormuz, with payment required in Chinese yuan routed through CIPS and Kunlun Bank, or in stablecoins. US dollars are refused. With roughly 20% of the world's oil supply passing through the Strait, this toll has forced global shipping companies to maintain substantial RMB reserves for the first time as an operational necessity rather than a strategic hedge. For related coverage on the Hormuz shipping disruptions, see ObjectWire's reporting on IMO vessel seizures and the dual blockade.
The knock-on effect is that Chinese buyers now have a credible argument that dollar-denominated commodity pricing creates unnecessary currency conversion friction for trade that is increasingly settled in RMB at multiple points in the supply chain. China spent $123 billion on iron ore in 2025. Shifting even a partial weighting of that settlement to yuan-linked benchmarks insulates the Chinese steel industry from the US Treasury's ability to apply financial pressure through dollar-denominated markets. The BHP deal is, in effect, a steel sector consequence of the Hormuz toll.
What Comes Next | Rio Tinto, Vale, and the COREX Precedent
The commodity market's immediate focus is whether BHP's concession triggers a cascade. Rio Tinto, whose Pilbara iron ore operations make it the second-largest supplier to Chinese steel mills after BHP, has been in parallel discussions with CMRG and has not disclosed any change to its pricing model as of April 26. Vale, the Brazilian giant whose ore carries a premium for its higher iron content, faces a structurally different negotiating position because its ore travels farther and incurs higher freight costs, making portside pricing comparisons less directly analogous.
For steel mill operators, the near-term question is whether COREX portside pricing, which reflects ore already imported and sitting in Chinese storage, is systematically cheaper than seaborne pricing. If COREX consistently underprices Platts at times of global tightness, then any contract with a COREX weighting produces buyer savings in tight markets, and any contract without one produces buyer losses. That asymmetry is what gives CMRG its leverage.
