South Korean courts have issued cumulative prison sentences against former President Yoon Suk-yeol totaling decades in connection with his December 2024 martial law declaration, including a life term for insurrection, 30 years for a related drone operation, a Supreme Court-upheld seven-year term for obstruction and resisting arrest, and a separate two-year conviction for receiving manipulated polls. These rulings, combined with ongoing appeals and additional indictments from a special counsel probe that concluded on August 24, 2026, have left Yoon in continuous detention since his re-arrest. No presidential pardon, bail grant, or appellate reversal has materialized to alter this trajectory before the market’s December 31, 2026 resolution date, supporting the 92 percent trader consensus that he will remain in custody.
