Circuit breakers are designed to halt trading temporarily when prices fall too far, too fast, giving markets time to absorb information and preventing panic-driven cascades. A Level 1 halt in South Korea is triggered when the index drops 8% or more from the previous close and holds there for at least a minute. The selloff quickly became one of the most dramatic single-day moves in the Korean market in years.
The damage was concentrated in chipmakers as Samsung Electronics and SK Hynix (two heavyweights that dominate the KOSPI) each fell about 10% intraday, dragging the entire index lower. Both companies are central to the global supply of memory chips and artificial-intelligence (AI) hardware, leaving the index acutely exposed to swings in tech sentiment.
Spillover Into Crypto What Comes NextWith global markets on edge over AI valuations and Fed policy, the next major move in digital assets may be decided as much in equity markets as onchain.
