- Rio Tinto was quoted 1.4% lower in London, underperforming the FTSE 100.
- Weak China output and retail data hit the demand case for miners.
- BHP and Fortescue also fell in Australia as resource stocks sold off.
Rio Tinto PLC fell in early London dealing on Monday, trailing the broader FTSE 100 as investors cut exposure to miners after weak Chinese activity data and a wider move out of risk assets. The stock was quoted at 7,655 pence, down 111 pence, or 1.43%, after opening at 7,698 pence; the FTSE 100 was down 0.12%, Hargreaves Lansdown data showed.
The timing is awkward. Rio had been trading near recent highs, with its London shares still below a 52-week peak of 8,275 pence set last week, after a rally built on firm copper prices and resilient iron ore demand. Iron ore feeds steelmaking, while copper is used in power grids, data centres and electric vehicles.
China put that demand story under pressure. Industrial output rose 4.1% in April from a year earlier, slowing from 5.7% in March and missing a Reuters poll forecast for 5.9%, while retail sales rose just 0.2%, far below forecasts for 2% growth. Zhiwei Zhang, president and chief economist at Pinpoint Asset Management, said exporters had helped offset weak domestic demand, “but not enough to fully offset it.” Reuters
Yuhan Zhang, principal economist at the Conference Board’s China Center, said the retail figures pointed to “still-weak household demand”. Lynn Song, ING’s chief China economist, said weak growth and rising inflation could complicate policy, adding that Beijing’s limited urgency for stimulus could change if the data worsen. Reuters
The broader tape gave Rio little cover. Asian shares fell as oil and bond yields rose after fresh Gulf attacks, with Brent crude trading at $111.34 a barrel and U.S. crude at $107.72. Risk-off — market shorthand for investors selling assets seen as more exposed to economic shocks — spread through equities and bonds. Citi analyst Scott Chronert wrote that broader participation was needed for further index upside and that investors needed a clearer view of how the Iran conflict might wind down.
Rio’s peers were hit too. In Australia, mining stocks touched their lowest in two weeks, with BHP, Rio Tinto and Fortescue down between 2.2% and 2.8% as the S&P/ASX 200 slipped 0.9% to 8,553.20 by 0026 GMT, a Reuters report carried by Business Recorder showed.
Rio’s operating backdrop is not weak, which makes Monday’s drop more about macro pressure than a fresh company miss. The group said last month that first-quarter Pilbara iron ore sales rose 2% to 72.4 million tonnes and copper production rose 9% to 229,000 tonnes; its 2026 guidance was unchanged. Chief Executive Simon Trott said “operating excellence” drove 9% growth in copper-equivalent production, a measure that converts output from different metals into a copper-price basis for comparison.

There is still a live cost risk. Rio said in April that direct supply-side impacts from the Middle East conflict had been limited, but Baden Moore, head of resources and energy research at CLSA Australia, said jet fuel and diesel shortages were the key second-half risk because they could affect equipment, logistics and personnel movement.
But the trade could turn quickly. A firmer Chinese policy signal, a rebound in copper or a pause in the oil shock would help miners. The downside is clearer for now: weaker Chinese steel output, higher fuel costs and a longer global bond selloff would make Rio look less like a clean copper-growth story and more like a leveraged bet on China and commodity inflation.
