KOSPI Stock & Crypto Market Crash [LIVE] Updates 26th June

South Korea’s KOSPI index fell 9.99% in a single session after sharp declines in Samsung and SK Hynix, triggering a 20-minute trading halt. Foreign and institutional investors were reported to have sold heavily, while retail investors made record net purchases of 11.55 trillion won, supported by elevated margin borrowing.

The sharp market reversal followed a strong rally driven by AI-related stocks. Investors will monitor whether selling pressure continues and whether regulators introduce measures to address market volatility.

Stock trade defaults at Taiwan securities firms reached $62 million in June, the highest monthly total since records began in 2019. Defaults have risen about 300% over the past two months, while margin purchases increased 160% over the past year to around $19 billion, near levels seen before the 2000 dot-com crash.

The data highlights growing leverage in Asian equity markets. Investors and regulators will watch whether rising defaults lead to tighter lending conditions or increased market volatility.

South Korea’s KOSPI index fell nearly 7%, prompting the Korea Exchange to halt program selling after a brief market loss. More than ₩366 trillion ($246 billion) in market value was erased, with major chipmakers SK Hynix and Samsung Electronics each falling more than 7%.

The sell-off wiped out the previous day’s gains driven by Micron’s earnings rally. Investors will closely watch the next trading session for signs of stabilization, particularly in semiconductor stocks.
