Mitsubishi Materials announced it will more than triple prices on tungsten carbide products used in hardened cutting tools, citing tight supply and soaring procurement costs due to Chinese export restrictions on tungsten, a critical material for manufacturing cutting tools, electronics, and military equipment [1]. The company stated that these price increases are unavoidable to maintain stable supply and operations, and the hikes are expected to impact a wide range of Japanese industries reliant on tungsten carbide tools [1]. China’s restrictions are part of a broader trend affecting critical minerals, with industry analysts warning of further price increases if the situation persists or if other countries implement similar measures [1]. Mitsubishi Materials has also restarted rare earth recycling operations to address supply challenges [1].
In the nickel market, S&P Global Energy analysts reported that prices are expected to remain high throughout 2026, driven by Indonesia’s production cut plans and disruptions caused by the Iran war, which has affected the supply of sulfur, a key ingredient in nickel processing [2]. Indonesia, the world’s largest nickel producer, has reduced supply by limiting raw material shipments and encouraging domestic processing, resulting in a surge in battery feedstock value [2]. Technical analysis shows strong support above $20,000 per ton and resistance near $24,000, with battery manufacturers and electric vehicle producers facing higher costs [2]. Vale Indonesia’s processing plants have reported increased input costs due to sulfur shortages, and S&P analysts recommend cautious trading strategies amid ongoing supply uncertainty [2].
Amanda Lacaze, CEO of Lynas Rare Earths, emphasized the need for government measures to expand the rare earths industry outside China, highlighting the importance of reliable access for high-tech industries such as electric vehicles, renewable energy, and defense [3]. Lacaze called for incentives and reduced regulatory hurdles to encourage investment in extraction, processing, and supply chain development in Australia and other regions [3]. Lynas is pursuing projects in Southeast Asia, including a rare earth metal plant in Vietnam, and has flagged higher costs for sulfuric acid and fuel due to regional conflicts, notably the Iran war [3]. Market analysis indicates rare earth prices remain volatile, with supply chain disruptions and elevated production costs contributing to price increases [3]. Trading sentiment is bullish for companies able to secure non-Chinese rare earth resources, and Lynas continues to invest in expanding its production capacity and partnerships in the Indo-Pacific region [3].
Across all three articles, market participants are closely monitoring developments in critical minerals supply chains, with particular attention to price volatility, supply disruptions, and government policy interventions [1][2][3].
CONCLUSION
Critical minerals markets, including tungsten, nickel, and rare earths, are experiencing significant price increases and supply disruptions due to Chinese export restrictions and geopolitical tensions such as the Iran war. Companies and analysts expect continued volatility and elevated prices, with calls for government intervention to diversify supply chains and reduce dependence on China. The market sentiment remains bullish for those able to secure alternative sources, and the impact is high across multiple industries.
