Key points:
- Bitcoin reached new local lows of $80,154 as downside pressure returned to South Korean equities.
- The KOSPI closed Thursday at 5,554 points, its lowest since early April, driven by a rout in tech stocks.
- Oil prices cooled, with Brent crude dropping more than 2% despite an “unjustifiable” Singapore fuel-tanker strike in the Strait of Hormuz.

As Cointelegraph reported, concerns over AI debt obligations, foreign capital outflows and competition from China contributed to the South Korean market rout, with KOSPI’s 200-day moving average dropping to as low as 5,450 points, a level not seen since late July. It ended Thursday’s trading session at 5,554 points, marking its lowest daily close since April 8.
