Yoon prepared martial law plan as early as October 2023: special counsel

A special counsel probe led by Cho Eun-seok concluded that former President Yoon Suk Yeol spent more than a year preparing the Dec. 3, 2024 martial‑law declaration—with planning traced to as early as October 2023 and discussions of martial law first raised after his May 2022 inauguration—and indicted 24 people, including Yoon, ex‑prime minister Han Duck‑soo, former cabinet members and senior military figures on charges tied to insurrection and foreign interference. Investigators say the effort was a deliberate bid to consolidate power by using the military to suspend normal politics, paralyze the National Assembly and establish an emergency legislative body, with personnel planning, operational talks, repeated contact with senior commanders and relocation of the presidential office to Yongsan to facilitate coordination; timing was chosen to reduce the likelihood of U.S. intervention amid the U.S. presidential transition. The team reported attempts to manufacture a justificatory security incident involving North Korea that did not provoke a response, found no evidence implicating the former first lady or senior judiciary officials, and has forwarded its factual findings to prosecutors who will seek convictions while courts make final determinations.

Analysis

A special counsel led by Cho Eun-seok concluded that former President Yoon Suk Yeol and associates spent more than a year preparing the Dec. 3, 2024 martial‑law declaration, with planning traced to October 2023 and references to martial law appearing as early as his May 2022 inauguration; the probe indicted 24 people, including Yoon, ex‑Prime Minister Han Duck‑soo, former cabinet members and senior military officials on charges tied to insurrection and foreign interference. Investigators cite seized notes, internal memos and testimony showing personnel planning, operational discussions, repeated contact with senior commanders, and the presidential relocation to Yongsan to facilitate closer military coordination. The team found the declared purpose was consolidation of power—seizing legislative and judicial authority via an emergency body—and that timing was chosen to minimize likely U.S. intervention during the U.S. presidential transition; attempts to manufacture a justificatory security incident with North Korea did not succeed. Prosecutors will pursue convictions while courts make final determinations; external signals show a strongly negative, risk‑off market sentiment and a meaningful market‑impact score, implying elevated near‑term political, legal and geopolitical risk for South Korea and potential policy paralysis during the litigation process.

Key Decisions for Investors

• Reduce or hedge direct exposure to South Korea‑focused equities and sovereign risk in the near term given heightened political and legal uncertainty
• Monitor court schedules, indictment/conviction milestones and U.S.–South Korea diplomatic communications closely and reassess positions ahead of those events
• Avoid initiating large, Korea‑domestic cyclical positions until legal outcomes reduce policy paralysis risk, consider duration‑limited defensive or non‑Korea exposures instead
• If maintaining Korea exposure, use downside protection such as options or position limits and prioritize companies with low domestic regulatory dependence and diversified revenue streams
