Price Hikes Reshape Hotspots; Supply-Chain Restructuring Deepens——March 2026
What Buyers Are Searching For
All categories jumped MoM — MCU +224%, DC-DC converters +197%, Flash +130% led the move, with only minor rank reshuffling inside the list.
Every brand rose too; TI and ST grew far stronger than the field, pulling the center of gravity toward the two majors as hike anticipation built.

What This Means for Your Supply Chain
Move before hikes land. With everything up, pre-build stock on MCU, power and analog now. Follow the majors' build-out. ST local China output and ADI's Thailand plant change where supply lands — align your sourcing. Qualify fast. The multi-category surge means broader exposure; accelerate alternate qualification.
For distributors, the edge is breadth — be ready across MCU, analog and power as the hotspot map widens.
Segment-by-Segment Outlook
Microcontrollers： STM32 surging on hike anticipation; lead times risk stretching.
Memory： Still climbing; now part of a broader up-move, not alone.
Analog & Power： Hike plans disclosed across the field; allocate early.
Supply chain： Localization (ST China, ADI Thailand) reshapes the geography of supply.
Leading Electronics is an independent distributor of electronic components based in Hong Kong. We focus on urgent shortage supply, cost-down programs, hard-to-find and obsolete (EOL) parts sourcing, and excess inventory handling — with original, traceable stock and third-party lab verification.
