South Korean Markets Tumble 8% as Tech Selloff Triggers Panic; Worst Weekly Drop Since March Looms

South Korean equities witnessed a sharp and broad-based selloff on Friday, with the benchmark KOSPI plunging more than 8%, as global risk sentiment weakened after a steep fall in US technology stocks.

Heavy Correction Hits Seoul Markets Amid Global Tech Weakness

The index dropped 8.18% to 8,199.81, marking its weakest weekly performance in over three months.

Semiconductor Stocks Lead the Collapse

Heavy selling was concentrated in index-heavy chipmakers:

Samsung Electronics fell over 9%
SK Hynix declined more than 9%

Together, these stocks account for over half of the index weight, amplifying the impact of the decline.

Circuit Breakers Triggered Amid Volatility

Market volatility surged sharply, triggering circuit breakers twice during the week, temporarily halting trading.

This highlights extreme intraday stress in the market.

Global Tech Weakness Spills Into Asia

The trigger came from weakness in US technology stocks, where investors turned cautious on:

AI spending sustainability
Hyperscaler investment slowdown fears
High valuation pressure in tech-heavy indices

Even strong demand signals from select chipmakers failed to lift sentiment.

Positioning-Driven Correction, Not Structural Damage

Market experts view the decline as a result of overcrowded positions and profit booking rather than a breakdown in fundamentals.

However, volatility remains elevated in the near term.

Broader Market Weakness Across Sectors

Selling pressure extended beyond tech:

LG Energy Solution fell 7.24%
Hyundai Motor dropped 7.55%
Kia Corporation declined 6.38%

This indicates broad risk-off sentiment across sectors.

Foreign Investors Exit Sharply

Foreign investors sold nearly ₩3 trillion worth of equities, adding strong downward pressure on the market.

Currency Weakness Adds Pressure

The South Korean won weakened to 1,547.2 per USD, reflecting capital outflows and risk aversion.

Market Outlook

Despite the sharp fall, the index remains significantly higher year-to-date. However, near-term volatility is expected due to:

US tech earnings trend
AI capex outlook
Foreign fund flows
Semiconductor cycle direction

Key Takeaway

The decline reflects a sharp unwinding of crowded tech trades rather than structural weakness, but volatility risk remains elevated.
