On the morning of November 6, South Korea’s KOSPI plunged shortly after opening, immediately triggering a circuit breaker and halting trading for 20 minutes.
Let’s look at the details. The index fell as much as 8.8% during the session, breaking below the 5,000-point mark and hitting a low of 4,911. This was the 11th time this year that South Korea’s stock market has triggered a circuit breaker. Major stocks took a beating: Samsung Electronics fell more than 10%, while SK Hynix was down nearly 14% at one point. South Korea’s finance ministry issued an urgent statement during the session, saying it would take measures to prevent excessive volatility.
Why did the market fall so sharply? The immediate trigger was an overnight collapse in U.S. tech stocks. The Nasdaq fell 5.5%, while the Philadelphia Semiconductor Index plunged 12.2%. Looking deeper, the trigger was the U.S. midterm elections: markets began worrying that AI and data centers could face tighter regulation, prompting a broad sell-off in U.S. tech stocks and wiping out $2.5 trillion in market value in a single day.
South Korea suffered the steepest losses because of the structure of its own stock market. The KOSPI is heavily weighted toward semiconductors, with Samsung and Hynix serving as bellwethers. When U.S. tech stocks collapse, South Korea’s market sits right at the front of the resulting sell-off chain, so its losses are naturally deeper than those in other Asian markets such as Japan’s Nikkei.
So this sell-off wasn’t caused by some independent piece of bad news in South Korea. Rather, fears over AI regulation in the U.S. were transmitted directly to Asia’s semiconductor supply chain. In the short term, sentiment and leverage are both driving the sell-off. Over the longer term, the key question is whether AI regulation will lead to substantive policy changes.
