South Korea election results 2025: Who won, who lost, what’s next?

Lee Jae-myung of the Democratic Party is set to become South Korea's next president after conservative Kim Moon-soo conceded defeat in a snap election triggered by the impeachment of former President Yoon Suk-yeol. With nearly 80% voter turnout, Lee secured over 48% of the vote, capitalizing on opposition to Yoon's martial law declaration and promising economic reform and improved relations with North Korea; he is expected to be sworn in on Wednesday. Despite facing ongoing trials related to corruption charges, Lee's win signals a shift in South Korean politics and a potential realignment of foreign policy, including navigating relations with the U.S. under President Trump.

Analysis

South Korea's political landscape has shifted with Lee Jae-myung of the Democratic Party securing the presidency with over 48% of the provisional vote in a snap election marked by a high turnout of nearly 80%, the highest since 1997. This election was precipitated by the impeachment of former President Yoon Suk-yeol following a controversial martial law declaration, an event Lee Jae-myung actively opposed and has pledged to investigate further. President-elect Lee, set for an expedited swearing-in on Wednesday, has outlined a policy agenda focused on pragmatic diplomacy, emphasizing the US alliance and trilateral cooperation with Tokyo—a stance similar to conservatives—while also seeking renewed dialogue and denuclearization talks with North Korea. Domestically, he aims to address economic inequality and has proposed a four-and-a-half-day workweek, signaling potential changes to the labor market. However, Lee's presidency commences under the shadow of five ongoing trials for corruption and other criminal charges, which he deems politically motivated. The provided "mixed" sentiment and moderate market impact score (0.6) reflect this complex environment, suggesting investors anticipate a period of adjustment and potential policy-driven market movements as the new government takes shape rapidly amidst these underlying uncertainties.

Key Decisions for Investors

• Closely monitor the incoming Lee administration's initial policy enactments, particularly concerning proposed economic reforms such as the shorter workweek and foreign policy overtures towards North Korea, for their impact on South Korean assets.
• The five ongoing legal trials against President-elect Lee represent a significant political uncertainty; investors should incorporate this risk into their assessment of South Korean market stability and governance outlook.
• Given the stated "mixed" market sentiment and moderate impact score, anticipate potential near-term volatility and re-evaluate exposures to South Korea as the new government's agenda on trade, particularly with the US, and domestic economic policies become clearer.
