South Korean courts convicted former President Yoon Suk-yeol of insurrection in February 2026, imposing a life sentence, followed by a 30-year term in June for related charges including abuse of power and aiding the enemy over a drone operation. He has remained in custody at the Seoul Detention Centre throughout multiple trials and appeals, with the Supreme Court upholding additional prison terms such as seven years on procedural violations tied to the 2024 martial law declaration. The severity of the convictions, combined with ongoing appellate proceedings under the current administration, has produced trader consensus that release before 2027 remains improbable absent a successful high-court reversal or executive action.
