Data compiled by Woofun AI shows that South Korea's Financial Supervisory Service Director Lee Chan-jin expressed deep regret over the introduction of Samsung Electronics and SK Hynix single-stock leveraged ETFs. On June 22, Lee acknowledged a policy misstep, noting that the instruments were deployed to redirect retail capital from overseas markets amid a strong won, but have instead fueled speculative excess. He highlighted that turnover rates nearing 200% allow securities firms to capture up to KRW 100 trillion in fees, leaving retail investors exposed to 'casino-like' dynamics without commensurate benefit.

Lee warned that market instability is intensifying, particularly within the semiconductor sector, where trading concentration masks underlying risks through statistical illusions of declining margin debt ratios. In response to these overheated conditions, the FSS is evaluating credit-related safeguards, including phased restrictions on margin trading, to shield middle-class households from potential shocks.

Additionally, Lee criticized the recent SpaceX IPO allocation failure, describing the process as 'unbelievable' and promising regulatory investigations to prevent future investor harm.
