AI demand, aluminium foil costs trigger rare capacitor price rises across China, Japan and Taiwan

The recent surge in aluminum electrolytic capacitor prices reflects a supply-demand imbalance driven by AI demand and constrained production capacity. Rising raw material costs have squeezed profit margins across the global semiconductor and AI server supply chain, forcing manufacturers to consider alternative technologies such as film or solid capacitors. From a compliance standpoint, geopolitical tensions have heightened supply chain vulnerabilities, especially amid U.S.-China tech decoupling, placing pressure on companies in Taiwan, China and Japan. Market players may respond by vertical integration or regional sourcing to secure resources. Over the next 12–24 months, sustained AI demand could lead to prolonged price increases, accelerating domestic substitution and technological upgrades across the electronics manufacturing ecosystem.
