Market Overview
Asian equity markets experienced a broad sell‑off on Wednesday, with the MSCI AC Asia Pacific gauge slipping roughly 2%. The decline was driven by a renewed semiconductor sell‑off that spilled over into broader growth stocks, while U.S. Treasury yields remained near multi‑decade highs, adding pressure to risk assets.
US Treasury and Commodity Context
Long‑dated U.S. Treasury yields rose to 5.3371% on the 30‑year note, the highest level since 2007, and the 10‑year yield hovered around 4.69% during Asian trading hours. The Federal Reserve’s July meeting minutes were awaited for clues on inflation outlook. The Treasury also announced a $16 billion issuance of 20‑year debt. Meanwhile, Brent crude prices stayed above $90 per barrel, reflecting ongoing tensions in the Middle East, particularly the lack of progress in the Iran conflict.
Korean Market Impact
South Korea’s KOSPI index tumbled 5.5% to 6,495.1 points after briefly falling as much as 6.4% earlier in the session. The index had previously rallied more than 2% on Tuesday, marking a six‑day streak of gains that was erased by the chip rout. Heavy profit‑taking and reassessment of AI‑related valuations, compounded by higher borrowing costs, drove the sell‑off. Samsung Electronics fell 7.3% (ticker 005930) and SK Hynix dropped 8.4% (ticker 000660), reflecting the heavy weighting of these semiconductor giants in the index. The rapid decline triggered a “sidecar” program‑trading halt, a mechanism designed to cool markets when selling becomes unusually intense.
Corporate Movers Across Asia
In Japan, the Nikkei 225 slipped 2.4% and the TOPIX fell 2.7%; Kioxia led the tech decline with an 8.9% drop, while TDK fell 4.1% and Sony lost 1.0%. In China, the CSI 300 and Shanghai Composite each fell about 2%, while Hong Kong’s Hang Seng was largely unchanged. Baidu’s shares plunged 12.5% after quarterly revenue missed estimates due to weak advertising demand. Conversely, Xiaomi rose 6.4% despite a sharp decline in second‑quarter adjusted profit, buoyed by a 15.9% jump in EV‑related revenue. Unitree Robotics surged nearly six‑fold in its Shanghai debut, its IPO being more than 8,000 times oversubscribed by retail investors. Regional indices also slipped: Australia’s S&P/ASX 200 down 0.3%, Singapore’s FTSE Straits Times down 0.36%, India’s Nifty 50 opened 0.3% lower, and Indonesia’s Jakarta Composite fell 0.6%.
Investor Sentiment and Survey Findings
Bank of America’s latest fund‑manager survey indicated that 59% of respondents are hedging AI downside risk by rotating into value, cyclical, and defensive sectors—more than double the proportion in July. Nearly two‑thirds of managers said they require clearer evidence of AI monetisation before increasing exposure.
Monetary Policy Outlook in the Region
Australia’s Reserve Bank of Australia Deputy Governor Andrew Hauser warned that rates might need to rise again if inflation risks become entrenched. Indonesia’s central bank was expected to keep policy unchanged when it announced its decision later in the day.
