Fortescue slides with ASX mining stocks ahead of Tuesday open

Fortescue slides with ASX mining stocks ahead of Tuesday open

SYDNEY, May 19, 2026, 04:08 AEST

Fortescue Ltd shares ended down almost 3% on Monday, dragged lower with other Australian miners as concerns about inflation and softer resource stocks put pressure on the S&P/ASX 200. The benchmark index slumped to a seven-week low, losing 1.45% to 8,505.3. Fortescue settled at A$21.95, off its previous A$22.60 close.

BHP shares lost 2.8% to end at A$58.77 and Rio Tinto slipped 3.63% to A$179.01, showing the weakness was not just about Fortescue. The sector took a broad hit, with pressure going well beyond a single Fortescue filing or mine update.

Brent futures traded over $110 a barrel late Monday in Sydney, but Singapore iron ore dipped 0.3% to $110.77 a tonne. That’s a tough setup for an iron ore exporter tied to diesel prices and China’s steel sector. ABC said Chinese industrial output lost steam in April, and retail sales saw their slowest growth since late 2022.

ASX cash trading is closed at this point. FMG’s next test on the live market is set for later Tuesday. ASX standard trading hours are 09:59:45 to 16:00 Sydney time, followed by the closing auction.

State Street Corporation and its named subsidiaries disclosed a 5.02% holding in Fortescue on Monday, according to an initial substantial-holder notice. The company said the group had a relevant interest in 154,412,720 ordinary shares after crossing the substantial-holder threshold on May 13. That was Fortescue’s only new exchange filing for the day.

Fortescue investors are still trading off the March-quarter numbers reported last month. The miner shipped 48.4 million tonnes of iron ore in the quarter, bringing nine-month shipments to a record 148.7 million tonnes. Full-year 2026 shipment guidance stays between 195 million and 205 million tonnes. The company said its hematite C1 unit cost was $18.29 per wet metric tonne. C1 covers the cash cost to produce a tonne before some wider company and finance expenses.

Market sentiment has turned more negative. UBS equity strategist Richard Schellbach told The Australian he’s “incrementally more downbeat” and sees an earnings downgrade cycle “in motion now,” with Brambles and Elders among the latest names to drag the ASX lower. The Australian

Fortescue is still seeing fuel as the main near-term risk to its margins. On the company’s April analyst call, Group CFO Apple Paget told analysts the diesel-price hit would likely show “around the middle of this current quarter.” Director mining operations Graham Howard said diesel is coming from existing suppliers.

Fortescue still has its green energy spending in view. The company said in April it will put $680 million into expanding by 200 megawatts of firmed green power in the Pilbara. That comes on top of the existing $6.2 billion decarbonisation plan. Data centres are key customers.

But it’s easy to see the downside. If iron ore drops and fuel and funding costs remain elevated, Fortescue has less buffer. Legal risks aren’t gone either. Last week, the company said the Federal Court ruled it has to pay the Yindjibarndi Ngurra Aboriginal Corporation, including A$150 million for cultural loss. Native title compensation refers to payments linked to legally recognised Indigenous land rights.

Tuesday’s session will see traders checking if FMG can stay above Monday’s A$21.785 intraday low. Attention will also be on BHP and Rio to see if they steady. Oil prices staying elevated could keep fuel costs in focus. The index could move first, ahead of any action in Fortescue.
