Internal tensions within South Korea’s ruling Democratic Party have intensified since Jung Chung-rae’s election as chair in August 2025, driven by policy disagreements with President Lee Jae-myung over legislative priorities and institutional reforms. Pro-Lee factions have voiced frustration with Jung’s confrontational approach and proposed changes to party voting rules, including a “one person, one vote” system adopted by the central committee earlier this year. These frictions coincide with preparations for the party’s next convention, widely expected in August 2026, at which leadership positions will be contested. Recent statements from Jung on constitutional measures and by-election strategy have not eased internal divisions, leaving traders to price in a high likelihood that he will no longer hold the chairmanship by year-end.
