Taiwan Stocks Plunge 1,655 Points Amid AI Valuation Concerns and Rising Interest Rates
Electronic Technology · Semiconductors · economic_daily · 2026-10-15
Taiwan's stock market suffered a massive sell-off on the 15th, dropping 3.41% as investors reacted to AI financing risks, high bond yields, and regional market weakness.
What Happened
Market Sell-off: The Taiwan Weighted Index plummeted 1,655 points on the 15th, closing at 46,969 with a 3.41% decline amid heavy trading volume. The sell-off was not isolated, as Japanese and South Korean markets also experienced significant losses, with South Korea's index falling over 8%.
AI Financing Risks: Concerns regarding the sustainability of AI-driven business models have intensified as CoreWeave bond yields spiked, signaling cracks in debt financing. Investors are also scrutinizing the financial performance of companies like Anthropic, leading to a broader reassessment of high-leverage AI growth strategies.
Interest Rate Headwinds: Recent CPI data has fueled expectations for a potential Federal Reserve rate hike in October, keeping U.S. Treasury yields elevated. This environment exerts downward pressure on the valuations of technology growth stocks, which are highly sensitive to discount rate fluctuations.
Valuation Reappraisal: Market sentiment toward the AI sector has shifted from optimism to skepticism as liquidity tightens. While technological progress remains rapid, the changing financing landscape has forced investors to prioritize balance sheet health, leading to ongoing volatility in the tech sector.
