South Korea’s former president Yoon Suk-yeol remains in detention at the Seoul Detention Center while serving a life sentence for insurrection over his 2024 martial law declaration, a verdict delivered in February 2026. Multiple additional convictions, including a seven-year term upheld by the Supreme Court in July 2026 and a separate 30-year sentence, have extended his custody as appeals proceed through higher courts. South Korean legal processes for high-profile political cases typically involve lengthy reviews without routine bail or early release, and no recent rulings or procedural shifts have altered this trajectory. Traders assign a 90% implied probability to “No” on release before 2027, consistent with the extended timeline of ongoing litigation and final sentencing enforcement.
