The worldwide market for microchip manufacturing inputs is experiencing a sharp upturn in costs, driven by the combined impact of geopolitical tensions and restrictions on raw material exports. According to industry intelligence, the price tags for several vital metals and chemical compounds essential to the semiconductor sector have doubled or even tripled over the last few weeks. This challenging scenario has been exacerbated by the ongoing unrest in the Middle East, layered upon previously established export constraints originating from China.
Refractory metals utilized in the machinery for compounding semiconductors have seen some of the most significant price hikes. Industry sources indicate that the costs associated with tungsten, tantalum, and molybdenum have essentially doubled. Furthermore, the market for gallium—a strategic element in fabricating GaAs and GaN-based chips—is under added strain. By early March 2026, its price reached approximately $2,100 per kilogram, more than double the rate seen at the start of 2025. A contributing factor has been China’s prohibition on exporting gallium to the US, which was enacted toward the close of 2024.
The Middle Eastern conflict has also disrupted the supply routes for both aluminum and helium. Because gallium is almost exclusively recovered as a byproduct of aluminum refining, the shutdown of several operations in that geographic area has propelled aluminum prices to a four-year peak. Uncertainty has been compounded by issues affecting helium supply, a critical gas needed for lithography processes and cooling systems in chip fabrication plants. Qatar accounts for over a third of global helium output, meaning any disruption to its flow immediately impacts the entire industry.
In response to these escalating risks, semiconductor manufacturers are starting to pivot away from their former “just-in-time” procurement strategy. Corporations are now building up material stockpiles and actively exploring alternative sourcing partners to prevent operational shutdowns. This proactive inventory building is particularly crucial for devices built on GaN and GaAs technology, which are widely employed in computer power supplies, portable computer chargers, network infrastructure gear, and Wi-Fi 7 equipment.
