Bitcoin's price has been sliding all year, but the way it's sliding is unusual. The cryptocurrency's annualized volatility stands at 48%, lower than the KOSPI's 63%. That's a rare inversion — and it says more about the KOSPI's wild swings than Bitcoin's calm.
Bitcoin's quiet slide
Bitcoin opened the year near $88,000 and currently trades around $63,000, a decline of roughly 29% year-to-date. From its October 2025 all-time high of $126,000, it's down nearly 50%. But the low volatility reading is due to a steady downward drift rather than sharp swings. Bloomberg's measure captures deviation from average daily returns, so a slow bleed doesn't register as high volatility.
KOSPI's wild ride
The Korean index hit a record high in June, but more than 650 of its 831 stocks fell. SK Hynix lost 27% of its value over three trading days, then surged by Korea's 30% daily limit once sentiment reversed. The Korea Exchange halted trading nine times this year, compared to just once in 2024. That's a lot of circuit breakers for a market that's supposed to be mature.
Retail leverage and regulator regrets
Retail investors hold most of the leveraged ETFs tracking Samsung and SK Hynix, which at their peak made up more than 70% of daily trading value. Finance Minister Koo Yun Cheol acknowledged regulators approved the leveraged products too quickly. The timing isn't great — those ETFs amplified the swings that triggered the halts.
The rotation story
Bitcoin's price pressure is linked to slowing ETF inflows and capital rotating into AI-linked stocks. Samsung Electronics and SK Hynix together make up more than half of the KOSPI's weight, driven by the AI boom. That's where the money is going. The question now is whether Bitcoin can find a floor as AI stocks continue to draw capital, or if the steady drift turns into something sharper.
