GFZ (German Research Centre for Geosciences): M5.62 earthquake struck New Zealand's South Island.

South Korea's Financial Services Commission (FSC) Chair Lee Eok-won said the commission will shortly announce supplementary measures targeting single-stock leveraged products. He said the key issue is the extent of their market impact and that the FSC will promptly formulate and publish measures. Asked whether the FSC is considering temporary trading halts amid sharp market declines, Lee said such steps could produce larger side effects and are under comprehensive evaluation. He flagged elevated volatility in the global semiconductor sector under a "supercycle"—rapid gains and swinging expectations—as a key backdrop to recent swings in Korean and global semiconductor stocks. Lee added that the sharply higher combined market caps of Samsung Electronics and SK Hynix have increased their weight in Korea's composite index, magnifying semiconductor moves' impact on the broader market.
