BofA: China core semiconductor sales rise 24% in June-August

China’s core semiconductor sales, excluding memory, grew 24% year over year in June–August 2026, accelerating from 18% in Q2; MPU growth rose to 70%, above the global rate of 40%. Memory sales surged 458% year over year and represented 60% of China’s semiconductor sales, although sequential growth slowed to 29% from 59% as price increases moderated. Third-quarter integrated-circuit export value growth accelerated to 128% year over year, versus 76% growth in imports.

Analysis

The key read-through is a split between demand breadth and revenue quality. Faster China MPU growth supports a durable domestic-computing demand thesis, but sales data alone cannot establish whether local chipmakers, foreign suppliers, or both captured that demand; export value growth likewise does not prove rising unit volumes or successful import substitution. The continued import expansion alongside exports argues against treating this as a clean near-term displacement of foreign vendors.

Memory is the near-term swing factor, but the deceleration in sequential growth alongside moderating price increases makes the very high year-over-year figures a poor signal for extrapolating earnings. Since memory accounts for a large share of the market, a price-led slowdown could dominate otherwise improving logic and MPU demand. That is a risk to memory-linked earnings expectations over the next 1–3 months if contract pricing rolls over; over 6–18 months, domestic computing demand and supply tightness could still support volumes and local capability-building.

Contrarian point: the export acceleration looks stronger than the evidence for competitive share gains. Customs value can reflect pricing and mix, and the data does not identify product origin, destinations, or units. Treat it as an industry-demand indicator, not proof that Chinese suppliers are taking global share. The thesis strengthens with unit-based export growth and rising domestic supplier share; it weakens if memory pricing reverses or imports continue to outgrow exports.

Key Decisions for Investors

• No immediate broad China-semiconductor overweight from this release alone. Use it as a demand signal, not a supplier-earnings upgrade, until company-level revenue, unit, and domestic-content data confirm who is capturing sales.
• Memory exposure: avoid chasing the backward-looking year-over-year growth. Reassess global memory producers such as Micron and SK Hynix after the next contract-pricing updates; a further price decline or weaker guidance would falsify the constructive supply-tightness case.
• Watch GigaDevice for evidence that MCU price increases translate into sustained realized pricing and margins; the article does not establish the size or persistence of the benefit. Treat any position as conditional on subsequent company disclosures.
• For the next 1–3 months, monitor memory contract prices, China semiconductor imports versus exports on a unit or product-mix basis, and supplier earnings guidance. Persistent export growth with improving domestic share would justify revisiting a China supply-chain beneficiaries basket; value growth alone is insufficient.
