受半导体类股大量抛售影响，韩国基准KOSPI指数于7月2日下跌超过5%，促使韩国交易所启动了卖盘侧熔断机制（sidecar）。
KOSPI指数开盘下跌4.46%，报7933.1点。截至上午9点08分，该指数下跌446.8点，跌幅达5.34%，报7856.61点。
韩国交易所于上午9点07分左右启动了卖盘侧熔断机制，在KOSPI 200期货指数下跌5%或以上后，暂停了程序化交易五分钟。该基准指数随后跌幅扩大至6.23%，跌至7790.16点。
美国市场隔夜下跌，包括纳斯达克100指数下跌1.5%以及费城半导体指数下跌6.3%，对市场情绪造成压力。三星电子股价下跌7.47%，SK海力士下跌7.73%。美联储主席凯文·沃什（Kevin Warsh）指出通胀风险已经缓解，从而降低了市场对7月份降息的预期。
交易员和分析师指出，在半导体板块亏损和美国科技股走软导致的急剧下跌后，卖盘侧熔断机制被迅速触发。一些人评论称其为“像时钟一样精准”或“循环恐慌”，突显了反复出现的波动性，而另一些人则详细列举了外国资金外流、韩元疲软以及美联储鹰派言论等因素。高参与度的账户分享了事实更新和分析综述，而非单纯转发链接。
