South Korean Retail Investors Shift Capital to U.S. Markets

Retail investors in South Korea, commonly referred to as ants, are shifting their capital toward U.S. markets following a significant rout in the domestic KOSPI index. In July, retail buying of U.S. stocks reached US$4.6 billion, marking the first time since February that overseas purchases surpassed domestic share buying.

South Korean retail investors are reacting to a 33 percent drop in the KOSPI from its June peak. This decline was primarily driven by losses at chipmakers Samsung Electronics and SK Hynix, fueled by concerns over Chinese competition and AI spending. Samsung Electronics alone accounted for 76 percent of the KOSPI's total value wipeout.

This capital flight undermines a government-backed initiative designed to lure investors back to the domestic market through corporate governance reforms and tax breaks. While SK Hynix provided a temporary boost to the won by repatriating funds from a US$26.5 billion raise, overall domestic stock trading account deposits fell to 102.8 trillion won as of August 7. Policymakers warn that the trend threatens to weaken the South Korean won and disrupts efforts to deepen domestic market participation.
