On September 22, the daily commodity price fluctuation rankings highlighted silicon carbide as the top gainer. The spot price of silicon carbide rose 3.28% in a single day, climbing from yesterday's 6,100 yuan per ton to the latest level of 6,300 yuan per ton.
Looking at the trend for silicon carbide spot prices, the latest reading as of September 22, 2026, stands at 6,300.0 yuan, marking a daily increase of +3.28%. Over the past week, the price has gained +6.78%, while the one-month increase is +8.62%. The data timestamp is set to 2026-09-22, with silicon carbide spot prices now at 6,300 yuan.
Reasons behind the commodity price surge: Silicon carbide, a third-generation wide-bandgap semiconductor material, sits at the upper end of the industrial chain. The rise in silicon carbide spot prices can be attributed to several key factors. First, supply contraction: smaller production capacities continue to exit the market, while leading manufacturers are running at over 90% capacity utilization. This has led to a tight supply situation for certain high-end and automotive-grade products. Second, expanding demand: the upgrade of AI data centers to 800V high-voltage power supply architectures, combined with growth in new energy vehicles, photovoltaic storage, and other sectors, has improved order visibility. Third, cost and pricing dynamics: overseas manufacturers such as STMicroelectronics and Infineon have implemented multiple rounds of price hikes. Packaging and testing resources are shifting toward high-value-added SiC products, further pushing spot prices upward. Fourth, improved market expectations: the progress of 8-inch substrate mass production and the continued industry scale expansion are reinforcing confidence in price increases across the supply chain.
Key associated stocks and their core business highlights: Kexin New Materials (with a price-to-earnings ratio of 31.3 and a total market capitalization of 9.49 billion yuan) focuses on refractory materials and silicon carbide composite materials for new energy battery applications. Its refractory products primarily serve industries including steel, non-ferrous metals, cement, and glass, and the company holds strong competitiveness in the field of breathable components for molten metal purification.
The runner-up on the list is isopropanol. On September 22, the spot price of isopropanol increased by 2.42% in a single day, moving from yesterday's 8,966.67 yuan per ton to the latest price of 9,183.33 yuan per ton. The trend for isopropanol spot prices shows the latest value at 9,183.33 yuan as of September 22, 2026, with a daily change of +2.42%. While the weekly change is -4.84%, the one-month gain stands at +23.40%.
Reasons behind the isopropanol price increase: Isopropanol, also known as 2-propanol, sits between upstream propylene and acetone and downstream solvent applications. Several factors are driving the price rise. First, a temporarily tight supply situation: some facilities are undergoing maintenance or running below capacity, reducing available spot quantities. Low inventory levels are supporting quoted prices. Second, stronger cost support: firm crude oil prices are lifting cost expectations for chemical products, with propylene and acetone providing a solid floor for isopropanol. Third, improved high-end demand: growing demand for high-purity isopropanol in semiconductors, display panels, PCB manufacturing, and lithium batteries is creating supply gaps in electronic-grade material, boosting market confidence. Fourth, downstream restocking: after a period of low prices, traders and end-users are purchasing on an as-needed basis, and improved transaction activity is pushing prices higher.
