KOSPI Rebounds as Indonesia Sinks to Six-Year Low on MSCI Threat

Key points

• South Korea’s KOSPI rose 1.8% to 5,768.01, recovering from previous losses, while individual semiconductor stocks like SK Hynix fell 2%.
• Indonesia’s Jakarta Composite dropped 5% to 4,937.21, its lowest level in six years, following MSCI warnings about potential reclassification from emerging-market status.
• China’s Q3 GDP grew 4.5% year-on-year, slightly exceeding forecasts, with retail sales rising 1.1% and industrial output expanding 5.5%.
• The Philadelphia Semiconductor Index fell 11.4% in its longest losing streak since 2008, driven by concerns over AI infrastructure financing and Chinese competition.
• U.S. equity futures rebounded, with Nasdaq 100 futures rising 1.3% and S&P 500 futures gaining 0.7%, ahead of a busy week of corporate earnings.

Background

This follows a severe sell-off in late October 2026, where the KOSPI hit a six-month low and triggered a circuit breaker due to chip stock declines. Indonesia had already plunged 11% on October 15, its steepest drop since 1998, after MSCI proposed reclassifying it due to transparency concerns. The current volatility reflects ongoing tensions between AI investment sustainability and macroeconomic stability.

How outlets are covering it

Investing.com highlights the divergence between KOSPI’s rebound and Indonesia’s deepening selloff, emphasizing MSCI risks and AI financing scrutiny. AP News focuses on broader European stock slips and oil price declines, linking them to geopolitical and inflationary pressures. Yahoo Finance notes a more positive tone, citing Fed Chair Kevin Warsh’s upbeat comments on AI and a general rise in Asian stocks, contrasting with the specific sectoral weakness noted by Investing.com.

Why it matters

The divergence in Asian markets signals shifting investor sentiment toward AI infrastructure viability and emerging-market stability. Indonesia’s potential reclassification could trigger significant capital outflows, while China’s stronger-than-expected growth may influence regional economic policies. The ongoing chip stock volatility reflects broader concerns about AI profitability and Chinese competition, which could impact global tech supply chains and central bank policies.

What to watch

Investors will closely watch U.S. megacap earnings this week, including Netflix, Tesla, Meta, and IBM, to gauge confidence in the AI trade. Additionally, markets will monitor inflation data and central bank responses, as well as any further developments regarding Indonesia’s MSCI classification and Chinese economic indicators.
