Key Points
South Korea's Kospi fell 8.3% on June 8, triggering a 20-minute trading halt.
Investors are selling AI stocks over overvaluation fears after a record rally.
Strong US jobs data raised rate hike expectations, pressuring tech valuations.
Iran-Israel strikes pushed Brent crude oil up 5% to $98 per barrel.
South Korea’s stock market halted trading for 20 minutes on June 8 after the Kospi index plunged 8.3%, marking the third circuit breaker trigger this year. Japan’s Nikkei fell 3.8%. The sell-off stems from three forces: investors abandoning overvalued AI stocks, a strong US jobs report raising rate hike fears, and renewed Iran-Israel conflict pushing oil prices up 5% to $98 per barrel.
Why Tech Stocks Are Crashing Across Asia
Investors are rapidly selling AI-linked shares after a record rally that analysts now view as overheated. South Korean chipmakers Samsung and SK Hynix led the losses, with Samsung closing down 10%. Chief investment strategist Charu Chanana from Saxo described the market as facing a “messy mix” of shocks tied to the tech sector. Tech stocks have seen a strong run in recent weeks, but investors are now “repositioning” over fears that AI investments may be overvalued.
Rate Hike Fears Follow Strong US Jobs Data
A surprisingly strong May employment report triggered the sell-off. The data raised expectations that the US Federal Reserve will hike interest rates in 2026, not cut them as some investors hoped. The Nasdaq fell 4.2% on June 7, its biggest drop in more than a year. Higher rates make expensive tech stocks less attractive to investors and increase borrowing costs for companies spending heavily on AI infrastructure.
Middle East Tensions Push Oil Higher
Iran and Israel exchanged missile strikes on June 8, marking the first military action since a ceasefire was agreed in April. The conflict pushed Brent crude oil up 5% to $98 per barrel. Rising energy prices accelerate market concerns about persistent inflation, which compounds pressure on central banks to raise rates. Oil prices fuel inflation fears that weigh on stock valuations.
How Asia-Pacific Markets Are Responding
European markets opened lower but with smaller declines. Germany’s Dax fell 0.7% and the UK’s FTSE 100 slipped 0.4%. Markets like South Korea and Japan are particularly exposed to tech shocks because their exchanges are dominated by semiconductor and AI-related stocks. The Kospi is now down 13% from last week’s record high, signalling a sharp reversal in investor sentiment.
Final Thoughts
The combination of AI profit-taking, rate hike expectations, and Middle East tensions has created a sharp pullback in global tech stocks. Investors should monitor whether this marks a healthy pause in the nine-week equity rally or signals a deeper correction.
