South Korea’s former president Yoon Suk-yeol remains in custody at the Seoul Detention Center following his February 2026 conviction and life sentence on insurrection charges tied to the December 2024 martial law declaration. Subsequent April and June 2026 rulings added a seven-year term for obstruction-related offenses and a thirty-year sentence in a separate drone-incursion case, with appeals pending at higher courts. The multi-trial process, combined with standard timelines for Supreme Court review of high-profile convictions, makes release by the end of 2026 improbable. Traders assign “No” a 90 percent implied probability because the accumulated sentences and procedural requirements create significant barriers to early release absent an extraordinary legal reversal within the narrow remaining window.
