London, May 19, 2026, 10:02 (BST)
- Rio Tinto was last seen near 7,561 pence, off about 2.1% from Monday’s finish. Shares hit a one-year high last week.
- London Stock Exchange traded during normal hours and the UK’s main share index moved up.
- Iron ore, Rio’s main profit source, ended Monday at $110.54 a tonne. Prices are still up this month.
Rio Tinto dropped in early London dealings on Tuesday. The stock lagged while the FTSE 100 pushed higher, with investors cutting back on big miners following a recent strong rally.
Rio Tinto shares traded at 7,561 pence, slipping from the prior close of 7,727 pence. In early deals, the stock moved between 7,554 and 7,652 pence, according to market data. The fall took Rio below last week’s 52-week high of 8,275 pence, though shares remain well above the past year’s low at 4,110 pence.
The drop landed even as UK stocks moved higher. The GB100, a stand-in for the FTSE 100, added 0.66% to 10,392. European stocks gained too after President Donald Trump said there was a “very good chance” for a deal on Iran’s nuclear program. Trading Economics
Metals stocks were under pressure. Glencore shares fell, joining other London-listed miners in the red. Google Finance data had Antofagasta off by about 2%. Rio moved in step with these declines, looking more like part of sector weakness than an isolated selloff.
Iron ore slipped 0.21% to $110.54 a tonne on Monday, Trading Economics said. Still, prices are up over 3% for the month. The drop puts some pressure on Rio, which is heavily tied to iron ore from its Pilbara mines in Western Australia.
There wasn’t much in the way of new headlines from companies to drive the shift. Rio Tinto announced Monday that Matthew Whyte will be the new group company secretary and secretary of Rio Tinto plc, taking over from Andy Hodges. Tim Paine keeps his spot as company secretary for Rio Tinto Ltd.
Rio’s operating numbers are holding up even as the market gets tougher. In April, the miner posted a 9% year-on-year jump in copper equivalent output, thanks to gains at Oyu Tolgoi and Pilbara. The metric puts all output on a copper basis. Chief Executive Simon Trott said Rio had already put the first “$650m of annualised benefits” from productivity efforts in place. Rio Tinto
Higher oil prices, rising bond yields and political uncertainty are making investors more cautious about buying cyclicals at current levels. James Smith, developed markets economist for the UK at ING, said there was “pressure to adapt the fiscal rules” in Britain. Ipek Ozkardeskaya, senior market analyst at Swissquote Bank, said energy prices had “started to bite”. Reuters
Rio has warned about operating risks tied to the conflict in the Middle East. Last month, Reuters said the company had seen only a small direct impact up to now. But Baden Moore at CLSA pointed to jet fuel and diesel shortages as the main threat for operations in the second half.
UBS Global Wealth Management CIO Mark Haefele said he still sees the bull case in play. Haefele said that higher yields aren’t likely to knock the bigger growth picture off course as long as activity holds up. For Rio, this means iron ore stays above recent lows, copper demand remains solid, and cost cuts come in on time.
Risks sit on the flip side here. If oil stays up, China cuts back on steel demand, or diesel and logistics get more expensive, Rio could see its earnings buffer shrink fast. Shares ran up solidly into last week’s high, leaving little slack for a rough start to the week on macro news.
