The real iron ore story isn’t the price, but who sets it

For more than a decade, a single benchmark (Platts 62% Fe) priced the trillion-dollar iron ore market. That is no longer the case. Prices now increasingly reflect a basket of indexes rather than one reference point, a shift that built quietly for years, accelerating into late 2025. Futures and swaps markets, built for decades around one benchmark, will need to catch up with this reconfiguration of iron ore pricing. Here is what changed, why, and what it means for anyone tracking the market.

So far in 2026, the 62% Fe benchmark has stayed contained, trading roughly between $100 and $110/t across the year, compared with the much sharper seasonal swings of prior cycles. While benchmark pricing has long assumed a 62% iron content standard, declining ore quality from ageing mines (Australia's Pilbara region) prompted a downward adjustment in benchmark specification down to 61% this year. Looking ahead, SGX 61% futures are trading within a narrow band anchored around 99-100 $/t over the coming months, with the front-month contract settling at 100.30 $/t at the time of writing.

Two opposing forces appear to be pinning the price in place. On one end, demand sentiment has clearly softened in China. Chinese steel PMI readings have stayed in contraction for months, and the property sector continues to weigh on construction steel demand. This is the kind of backdrop that would normally drag imports towards the bottom, but deteriorating ore grade in China and surplus buying have kept import momentum going.  Chinese imports are expected to surpass 1.3Bt for the first time this year. This is now more of a supply story as production pace and inventory levels are high, putting overall downward pressure on prices. On the other end, freight rates have helped keep benchmarks higher.

A third factor of growing importance is now playing out. Ongoing miner negotiations with China Mineral Resources Group (CMRG) has reshaped term supply contracts and split negotiations into distinct, sometimes competing, index camps. Chinese steelmakers reportedly view CMRG as a comparatively fair counterparty, and the entity has become the single most consequential actor in a market that used to be priced almost mechanically. Estimates indicate it handles anywhere between >60% of China’s iron ore imports.

Overall, downside pressures outweigh the upside, keeping prices just under $100/t through H2 2026.  A sustained recovery above $100/t would likely require an improvement in Chinese manufacturing and construction activity, a slower Simandou ramp-up, or meaningful supply disruption. Hormuz remains a key monitorable from a freight perspective.

The structural transition to a multipolar indexation

CMRG interplay plausibly explains some of the band-narrowing. Each standoff injects a short, policy-driven supply-risk premium that offsets the weak demand and stops the price from testing new lows. Each resolution removes that premium and caps the upside before it runs far. It is a different mechanism from the classic seasonality story - restocking cycles, weather, port congestion. The result is a market with a soft floor and, so far, nothing forceful enough to punch through it.

At the centre of the negotiations, are the “Big Four” miners still supplying more than two thirds of China’s iron ore imports. For major producers with established relationships with large Chinese buyers, this dynamic reinforces their competitive positioning against smaller or newer suppliers. That said, the “Big Four” share of China's imports has quietly slipped to a decade low as Beijing spreads its buying further afield. But the volume tonnage remains highly substantial.

BHP becomes first of the “Big Four” to adopt COREX in its iron ore pricing formula

Following a contractual dispute that led to temporary Chinese procurement restrictions on some of its cargoes, BHP settled with CMRG in April 2026. China continued to import BHP products during the company’s pricing dispute with CMRG. Jimblebar Fines are now a weighted average of four seaborne and portside indices (COREX 61% Portside, Argus 61% Seaborne, Mysteel 61% Seaborne, Mysteel 61% Portside). Just over half of the product is now priced through China's yuan-denominated portside index, converted to US dollars, alongside a 1.8% rebate per vessel on term contracts. Platts continues to dominate the benchmark for its other products, but it gives CMRG a template it has already tried to apply elsewhere.

The playbook spreads to FMG

Fortescue shifted to a temporary pricing using an average of China’s Mysteel index and the Argus Iron Ore Index for its products, while its higher-grade Iron Bridge concentrate is priced against the Platts 65% index. Starting 15 July, CMRG has placed buying restrictions on Super Special Fines (56.5% Fe) and Fortune Fines (55.0% Fe). A similar playbook to the one it ran with BHP last year. So far, the impact looks contained. China’s daily imports from Anderson point have only slightly fallen, with the last Super Special Fines discharge on 16 July even as FMG continues to discharge some of its other products. The early strain is showing up elsewhere, though a handle of vessels waiting outside Chinese ports, a small but early signal worth watching if the standoff runs as long as BHP's did.

Other negotiations are a mixed bag

• Long reliant on the Platts index, Rio Tinto agreed in late 2025 to trial the Fastmarkets 61% Fe Fines Index under CMRG pressure. It held off adopting Beijing's COREX index directly, citing its short data history and portside only methodology.
• Vale has utilised CMRG to sell cargoes on the spot market, helping optimise output and distribution. As of now, the miner has no long-term contracts or fixed price arrangements with the Chinese entity, maintaining instead a flexible, market-based sales structure. Vale maintains a different pricing strategy due to its premium, high-grade ore and pellets with negotiations reportedly based on pricing data published by Fastmarkets.
• After more than a year of restricted sales where Chinese buyers were pressured to avoid Hancock’s Roy Hill fines on the spot market, CMRG and Hancock resolved their dispute, with CMRG securing exclusive sales rights.
• CMRG is reportedly discussing becoming an exclusive sales agent for some cargoes from Brazil's CSN Mineração, echoing an earlier arrangement with Australia's Roy Hill, a step that would put China's buyer inside the transaction flow itself, not just at the negotiating table.
• Kumba Iron Ore (Anglo American) is also in contract talks with CMRG, with deal expected later in the year.

What it means going forward

Where this settles in a difficult question. The market could converge on one dominant multi-index standard that most miners eventually adopt, or stay fragmented, with each producer running its own basket depending on how its CMRG negotiations go. Can COREX itself become the de facto reference for China-bound cargoes over time given how hard CMRG has pushed for its adoption elsewhere?

Underlying all these scenarios is a more basic split that hasn't gone away: a dollar-priced, seaborne-index world for the rest of the market, against a yuan-priced, portside-index world that China is trying to build for itself. Whether those two systems converge, coexist, or pull further apart is arguably the bigger story than any single miner's contract terms. Switch from annual pricing anchored to Platts average to a quarterly, spot-linked price basket favour Chinese buyers on the commercials and is likely to have an impact of miner revenues.

Going ahead, we expect mid-tier miners' negotiating leverage to shrink even as China's exposure to their volumes grows. West and Central African iron ore projects are widely seen as the long-term route for Chinese buyers looking to reduce their reliance on Australian and Brazilian suppliers, and Guinea's Simandou is the clearest example in motion. Please see the latest Iron Ore Balances dataset for an Excel file detailing our 18-month ahead forecasts for major iron ore importers and exporters, crude steel production forecasts, quarterly projections for major miners, and iron ore price forecasts.

In the near term, negotiations will lead to a fragment basket of indices, one that works for both CMRG and the miners. Portside prices move on administrative pressure rather than physical supply and demand, which has been a key pain point for miners in these negotiations. So, it is unlikely that the portside COREX index will gain complete popularity. BHP's 51% Jimblebar fines deal is a symbolic first, not a wholesale shift. While we expect to see more miners opt for yuan dominated indices into their basket, dollar dominance remains entrenched for now.

High-grade producers look set to keep the upper hand. Even as the benchmark 61% Fe price is forecast to drift lower through 2026 and into 2027, the premium for high grade ore will hold up.
