The chain this week — 2026-08-24

BIS Entity List revision (2026-08-24): BIS removed two Hong Kong addresses for Arrow Electronics (Hong Kong) Co., Ltd. from the China destination list — a de-listing, not a new restriction. No new semiconductor-equipment or advanced-chip controls on China appeared in any BIS notice this cycle. This is a data point against any near-term China export-control escalation tightening the semi-equipment or foundry layers. Standing tail risk remains, but this week added no evidence for it.

HBM still sold out into 2027 (data as of 2026-08-18): TrendForce's August 18 NAND Flash release confirmed memory suppliers are steering capex toward DRAM/HBM and away from NAND, keeping HBM bit-supply structurally constrained. Separately, NVIDIA has already adjusted HBM configurations on Rubin Ultra in response — the same demand-rationing signal that appeared with Vera Rubin earlier this year. HBM is ~50% of B200 manufacturing cost at current contract prices (~$15/GB for HBM3e); scarcity at this layer flows directly into system BOM and delivery schedules. This is a reinforcing data point for Memory (HBM) / mid-term = binding (yes).

TSMC approves ~$29.4B capex tranche, explicitly covering CoWoS (2026-08-11): TSMC's board resolutions earmarked capital specifically for advanced packaging capacity installation and upgrade alongside leading-edge fab construction. Advanced nodes were 77% of Q2 wafer revenue on record $40.2B quarterly revenue (+33.7% YoY). The capex commitment confirms CoWoS demand pressure is real enough to warrant board-level capital allocation, but new capacity takes 12–18 months to qualify — it does not relieve 2026 tightness. Data point consistent with Foundry & packaging / mid-term = binding (yes).
Standing constraint view: no change. Memory (HBM) and Foundry & packaging remain binding at mid-term; Electrical gear and Power generation remain binding now. Nothing this week shifts any layer's status.
