Market Analysis
The bear case, which clearly dominates current pricing, centers on Han’s trajectory as People Power Party (PPP) leader and former justice minister. He appears focused on national politics and potentially the 2027 presidential race rather than stepping down to Seoul’s mayoral office. Seoul Mayor Oh Se-hoon, also from PPP, remains popular and would likely seek re-election, making an intra-party challenge politically costly. Additionally, Han’s legal background and prosecutorial career don’t align with the administrative governance profile typically sought for mayoral candidates. The Democratic Party will likely field a strong challenger given Seoul’s swing-city status, and Han has shown no indication of pivoting from national leadership to municipal administration.
The bull case requires significant political realignment. If Han’s national standing deteriorates—perhaps through party infighting or poor PPP performance in the April 2024 National Assembly elections’ aftermath—he might seek the mayoral office as a political reset. A scenario where Oh Se-hoon declines to run or faces a major scandal could create an opening. Han could theoretically position a Seoul mayorship as an executive proving ground before a presidential bid, similar to how Park Won-soon used the office. However, this would require Han announcing intentions by late 2025 to build campaign infrastructure for the June 2026 election.
Key catalysts include PPP’s internal dynamics through 2025, any announcements from current Mayor Oh Se-hoon about his 2026 intentions (typically declared 6-8 months before the election), and Han’s own political positioning statements. The candidate registration period in spring 2026 represents the hard deadline. Traders should monitor Han’s public statements about political ambitions, PPP approval ratings, and whether he maintains his party leadership role or faces pressure to step aside.

Frequently Asked Questions
Could Han Dong-hoon run for Seoul mayor while remaining PPP party leader?
This would be highly unusual in South Korean politics, as party leadership is a national role that typically precludes simultaneous mayoral campaigns. He would likely need to resign the party position to credibly pursue the Seoul race.
What would happen if both Han and current Mayor Oh Se-hoon wanted the PPP nomination?
The PPP would conduct primary elections among party members and potentially include public opinion polling to determine their candidate. Given Oh’s incumbency advantage and Han’s national profile, this scenario would create a damaging intra-party split.
When would Han need to declare his candidacy to be competitive?
Serious candidates typically announce 6-12 months before South Korea’s local elections, meaning Han would need to signal intentions by late 2025 or very early 2026 to organize campaign operations, fundraising, and voter outreach for the June 2026 election.
