Why the Auto Allocation Story Just Flipped — and What That Means for Buyers
For the first time since the 2021 shortage began, automotive semiconductor inventory is in genuine oversupply. NXP, Renesas, and Microchip have all reported elevated automotive MCU inventory through 2026 as EV growth slowed and ICE vehicle production normalized. The result: spot pricing on common S32, RH850, and PIC automotive MCUs has dropped below 2020 levels for many part numbers — a complete reversal of the 2022 narrative.
The rebalancing is uneven. Mature-node 8-bit and 16-bit MCUs (PIC, RL78, S08, MSP430-class parts) are widely available and pricing has normalized. So have most basic CAN transceivers and analog power management. But high-performance 32-bit MCUs running on advanced nodes — RH850 in the latest geometries, S32G for ADAS, Aurix TC4xx for inverter control — remain on allocation as the automotive industry continues to densify each vehicle's electronic content.
For buyers who got burned during the 2021–2023 cycle paying premium spot pricing for allocated automotive parts, the obvious move is to revisit inventory and pricing strategy. Many of the components held as safety stock at elevated prices are now worth less than what was paid. Meanwhile, the parts that are still constrained are increasingly the ones that don't have easy second sources.
