The Securities laws and regulations of Korea are very similar to that of the U.S. However, the enforcement against market manipulation heavily relies on criminal enforcement. This prioritization of criminal prosecution over administrative and civil enforcement makes it difficult for Korea to protect investors, especially in the post-Morrison world where market manipulation may migrate from foreign markets to Korea. Is future reformation of market manipulation law needed in Korea? Historically, the model of Korean securities laws is Japan’s, and the Japanese securities law benchmarked the U.S securities law. Therefore, the core anti-market manipulation law of Korea is almost identical to the U.S securities laws. However, substantial differences between the markets and enforcement history made Korean enforcement quite different. In Korea, the securities law’s primary enforcement tool is criminal prosecution. Civil enforcement by securities market regulators is scarce in Korea, and a class action by private investors is tough to bring. Using this criminal enforcement mechanism against foreign market manipulators is almost impossible in practice. The enforcement system, which heavily relies on criminal enforcement could be problematic, especially in the post-Morrison world. Cross-border consistency of civil, administrative, and criminal enforcement is critical to protect investors against the market manipulator who seeks enforcement arbitrage between countries after the U.S. Supreme Court Morrison decision applied U.S. securities laws only to transactions inside the U.S. This dissertation will examine various options for regulatory enforcement reform in Korea that would build on Korea's distinctive institutions and enhance administrative, civil, criminal securities regulation mechanisms against market manipulation.enSecurities EnforcementSecurities FraudSecurities LawSecurities Market ManipulationSecurities RegulationSouth KoreaToward Integrative Securities Market Manipulation Regulation in Korea: Why does Korean regulation rely heavily on criminal enforcement?
