After the Indonesian government confiscated part of the Weda Bay nickel mine held by China's Tsingshan Holding Group, nickel prices on the London Metal Exchange (LME) rose 1% to $15,305 per ton. The confiscated area is 148 hectares, allegedly due to license violations.Weda Bay is the world's largest battery-grade nickel production base, jointly developed by Tsingshan Holding and France's Eramet. After the confiscation, LME nickel futures prices rose 1% in a single day, while other industrial metals showed mixed performance: copper up 0.1%, aluminum up 0.2%, lead down. Given that Indonesia contributes over 50% of global nickel supply, and recently due to rainy seasons and export quota restrictions, Indonesian nickel smelters have faced raw material shortages. President Prabowo also emphasized a crackdown on illegal mining, and analysts pointed out that this incident highlightsthe policy risks of Indonesia as a major nickel producer, which may exacerbate volatility in the global electric vehicle battery supply chain.
