South Korea stock market halted after sharp opening selloff
An 8% opening drop triggered circuit breakers, while SK Hynix slid to 1,904,000 won intraday and quoted prices later rebounded on trade.xyz and Binance, BlockBeats reported.
Fact Check
Multiple independent breaking-news reports timestamped around 00:05–00:30 UTC on June 8, 2026 confirm the KOSPI plunged sharply at the open and a circuit breaker was triggered, halting trading. Bloomberg's Joe Weisenthal (@TheStalwart) cites 8.8% while several other posts (GlobalFlash, Pulse Alpha, Grok) cite ~8.4%—the discrepancy reflects different points in time during the opening session; the claim's 8.4% opening figure matches the initial reports. The Semiconductor Insider post confirms a >8% drop with a 20-minute circuit breaker pause, and the TradingKey June 5 article documents the unfolding selloff context (Broadcom AI guidance miss, heavy foreign outflows in Samsung/SK Hynix). The corroborating evidence is consistent across multiple sources.
Summary
South Korea's stock market was halted after a sharp opening selloff triggered circuit breakers, with a June 8 BlockBeats update putting the initial drop at 8%, versus an earlier 8.4% figure in prior coverage.
