Advantest Corporation (6857.T) dropped 9.64% and Furukawa Electric (5801.T) fell 9.29%, dragging the Nikkei 225 down 4.15% to 69,360.88 — the largest single-session decline in the index in recent months. The Nikkei VIX surged 7.64% to 33.12, reflecting a sharp spike in near-term implied volatility.

KOSPISouth Korea's KOSPI recorded its worst weekly performance of Q2 2026, closing Friday at 8,411.21, down 5.81% on the session. The decline was concentrated in semiconductor heavyweights Samsung Electronics and SK Hynix, which had surged 35% and 60% respectively during April's record 31% monthly gain. SK Hynix is separately planning a nearly $30 billion US listing, one of the largest of its kind, with the deal's timing now complicated by the broader AI sentiment shift and elevated market volatility.

USD/CNY firmed to 6.7975, up 0.11% on the session, reflecting modest renminbi softness. Chinese macro data remains mixed: industrial production rose 4.5% YoY in May while retail sales contracted 0.6% YoY — the first annual decline since late 2022 — and property investment fell 16.2% YoY in the first five months of 2026, underscoring continued consumer and real estate sector stress.

ASX Utilities (+1.01%), Materials (+0.81%), and Information Technology (+0.81%) led sector gains, while Health Care (-1.30%) and Industrials (-1.17%) lagged.
