South Korea’s opposition People Power Party plans to submit a National Assembly request on Sept. 3 for an investigation into allegations surrounding the introduction of single-stock leveraged ETFs tied to Samsung Electronics and SK Hynix. Rep. Seo Il-jun said retail investors are estimated to have lost about 54 trillion won ($39 billion) through the products. The party is considering calling Mirae Asset Financial Group Chairman Park Hyeon-joo as a witness and wants investigators to examine whether former presidential policy chief Kim Yong-beom met Park during the rollout and whether any collusion or conflicts of interest influenced policymaking. The PPP said it would pursue a special counsel investigation if serious legal violations are confirmed, and would continue pressing for one if the parliamentary probe fails to advance. The investigation would require agreement from the Democratic Party.
