Shares of the UK’s biggest mining companies advanced on Wednesday, with investors moving back into heavyweight resource names after a period of commodity-market volatility linked to geopolitical tensions in the Middle East.
At 05:58 ET (09:58 GMT), Rio Tinto, Antofagasta, Glencore and Anglo American were all trading higher, posting gains that ranged between 0.5% and 5.7%. Those moves helped push the FTSE 100 index back above the 10,300 mark.
The sector-wide uplift tracked a broader stabilisation in metals prices following weeks of price swings tied to the Iran conflict, a development that had earlier driven Brent crude above $100 a barrel and unsettled global equity markets.
Optimism about possible diplomatic progress in U.S.-Iran talks has reduced some of the risk premiums that pressured commodity-sensitive stocks through much of March, encouraging a rotation back into cyclical and resource-focused equities.
Copper-focused Antofagasta was among the stronger performers, a reflection of firmer demand for base metals. Diversified miners Glencore and Anglo American also saw gains, supported by their exposure across a range of commodities including copper, cobalt, zinc and platinum group metals.
Analysts and investors have been positioning around an environment of elevated commodity prices and renewed appetite for resource stocks, which some market participants view as a hedge against inflation and a weakening dollar.
Precious metals have also seen notable moves this year. Gold is trading about 16% higher so far in 2026, while silver has experienced a substantial rise amid robust industrial demand from the solar and electronics sectors.
The FTSE 100 has had a volatile run in 2026, initially breaching 10,000 in January before giving back part of those gains during March’s geopolitical flare-up. The recent improvement in sentiment underscores how sensitive commodity-related equities remain to shifts in geopolitical risk and commodity-price dynamics.
