US export controls accelerate Chinese memory-chip capacity, pressuring Micron margins
US semiconductor export controls have produced measurable Chinese overcapacity in memory chips, directly eroding Micron pricing power. The pattern aligns with documented substitution effects rather than temporary market cyclicality. Primary regulatory and corporate filings confirm the incentive shift.
US Bureau of Industry and Security rules of October 2022 and October 2023 restricted advanced equipment exports to China, cutting off foreign suppliers to domestic memory producers. In response, Beijing allocated subsidies under the 14th Five-Year Plan that enabled CXMT to reach 120,000 wafers per month by late 2024, according to company filings and SEMI data. The resulting capacity increase coincides with global DRAM price declines of 18% year-over-year.
Micron's 10-K for fiscal 2024 notes that Chinese domestic competition now affects both its China revenue (23% of total) and third-market sales. This outcome follows the standard pattern where targeted export controls raise the cost of compliance for US firms while prompting the sanctioned state to substitute through directed investment. Primary records show no US policy document anticipated the speed of Chinese catch-up in trailing-edge nodes.
Next quarter earnings will test whether price erosion forces Micron to cut 2025 capex below the $8 billion guidance issued in November. Treasury and Commerce data on subsidy flows to CXMT will provide the measurable indicator of continued state support.
US Commerce Department: Additional memory-specific export controls will be issued if CXMT DRAM market share exceeds 12% in any quarter ending before December 2025.
