South Korea's KOSPI index fell more than five percent [1] on Friday, May 12, 2024, after government remarks regarding an AI national dividend sparked market confusion.

The sudden volatility highlights the sensitivity of foreign investors to policy shifts in the technology sector. A rapid sell-off threatened market stability, forcing the Korea Exchange to implement emergency cooling measures to prevent a total collapse.

The plunge occurred during early trading hours, with the KOSPI dropping to around 8,100 points [2]. The decline was so rapid that the Korea Exchange activated a sell-side sidecar eight minutes after the market opened [3]. This mechanism triggered a five-minute program-trading halt [4] to curb the downward momentum.

Market analysts attributed the crash to comments made by presidential policy chief Kim Yong-beom [5]. Kim said he planned an "AI national dividend," a plan intended to distribute profits from artificial intelligence [5]. However, the remarks created significant uncertainty among global traders regarding the potential impact on corporate earnings and tax structures.

Foreign investors responded by exiting their positions in a massive net sell-off exceeding 5 trillion won [6]. This exodus of capital from the equity market coincided with an unusual surge in the currency market. The Korean won rose to its highest level since the 1997 financial crisis [7].

While some reports focused on the technical triggers of the sidecar, other sources said the policy chief's remarks were the primary catalyst for the instability [5]. The intersection of AI policy and fiscal distribution appears to have alarmed the international investment community, leading to the rapid liquidation of assets.

The market reaction demonstrates a high level of volatility surrounding South Korea's integration of AI into national fiscal policy. The simultaneous crash of the stock index and the surge of the won suggests that while equity investors fled, there may have been a separate, aggressive hedge or speculative move in the currency market. This event underscores the risk that ambiguous policy language regarding 'national dividends' can be interpreted by global markets as a threat to private sector profitability.
