Monolithic Power Systems and STMicroelectronics' supply inputs tighten as solvent and carbon black shortages build
Report by JNK Research
Electronic-grade solvent allocation stopped for non-contract customers across Asia as of early Mar 26. No spot supply is available at any price in Taiwan, South Korea or Singapore. Force majeure from Formosa Petrochemical and PCS, combined with cracker cuts at LG Chem and Lotte Chemical to 54-73% utilisation, pushed naphtha-derived feedstock prices ~30% higher. The disruption spans legacy analog, DRAM, NAND and leading-edge logic with no node insulated. Conductive carbon black, a separate petroleum-derived passive component input, is developing a parallel shortfall into a supply chain already running at near-80% utilisation. China based foundries serving MPWR and STM are the base case for 2Q26 impact. Click here to access JNK’s note.
