Global equity markets witnessed sharp turbulence on Monday as concerns over a potential artificial intelligence (AI) bubble triggered a massive sell-off, dragging South Korea’s benchmark index KOSPI into a steep decline. Within just a few hours, global market capitalization reportedly eroded by nearly ₹22.5 lakh crore (around $270 billion), intensifying fears across financial markets.
The unprecedented sell-off has exposed severe concentration risks across Asian tech-heavy indices, triggering multi-tier risk-off protocols from Mumbai to Tokyo.

The Historic Intraday KOSPI Halt
South Korea’s KOSPI index came under severe pressure during intraday trading and closed with a sharp decline of around 8.29%, settling at 7,484.41. This marks one of the steepest single-day losses since March. The sudden fall was severe enough to trigger an emergency level-one circuit breaker, freezing all equity, futures, and option trading for 20 minutes as panic selling overwhelmed the exchange’s immediate liquidity buffers.
Market observers noted that the crash represents only the ninth time in the history of the Korea Exchange that a formal trading halt was forced by intraday price drops exceeding the critical 8% threshold.
A Convergence of Global Macro Shocks
The market deterioration was fueled by three separate global headwinds hitting technology portfolios simultaneously:
- The Broadcom Guidance Disappointment: While Broadcom’s fiscal Q2 financial numbers beat Wall Street expectations, its unrevised full-year AI semiconductor forecast fell flat. This broke the “beat-and-raise” cycle that tech investors grew accustomed to, causing the Philadelphia Semiconductor Index to plunge 10.26% on Friday and setting a brutal tone for Asian markets.
- Geopolitical Escalation in West Asia: Over the weekend, fresh missile exchanges between Iran and Israel broke the uneasy ceasefire established in early April. The closing of regional airspaces and subsequent hardening of international crude oil prices above $93 a barrel placed immediate inflationary pressure on energy-importing Asian economies.
- Aggressive Foreign Capital Outflows: Driven by a stronger-than-expected US jobs report that revived aggressive Federal Reserve interest rate hike anxieties, foreign institutional investors initiated structural panics. The South Korean won plummeted to a 17-year low, crossing the psychologically vital 1,560 per US dollar threshold and accelerating capital flight.
Mechanical Deleveraging Hits Chip Giants
Over the past two years, the global AI sector has been a major driver of equity market gains, attracting significant institutional and retail investment. South Korean giants such as Samsung Electronics and SK Hynix emerged as key beneficiaries of this boom, supported by soaring demand for high-bandwidth memory (HBM) chips used in AI data centers. By the end of May, both chip manufacturers had achieved historic valuations, with SK Hynix breaking the $1 trillion market cap threshold.
However, because these two companies command nearly half of the total weight of the KOSPI index, they became massive systemic liabilities during the downturn. Driven by automated daily adjustments within leveraged investment products, institutional algorithms executed forced unwinds. Samsung Electronics crashed 8.51%, while SK Hynix skidded 7.29%, dragging the broader index down mechanically.
Is the Tech Trade Broken?
The severe correction sent immediate shockwaves across domestic financial hubs. India’s benchmark indices, the NSE Nifty 50 and BSE Sensex, exhibited high-frequency volatility during the session, tracking global risk avoidance before minor defensive domestic buying limited local losses.
Despite the historic nature of the drop, elite banking strategists at Goldman Sachs are counseling long-term caution over blind panic. Market analysts point out that unlike the speculative dot-com bubble of 1999, the current semiconductor upcycle is backed by massive institutional profitability. Because Samsung and SK Hynix continue to trade at forward price-to-earnings multiples of approximately six times—a massive discount compared to their American tech peers—some fund managers view the liquidity-driven reset as a high-potential long-term structural buying opportunity.
