South Korea

経済・産業概況

South Korea is a high-income OECD economy with a nominal GDP of approximately $1.86 trillion in 2025, ranking among the top 15 globally. The economy is driven by export-oriented industries, particularly semiconductors, automobiles, shipbuilding, and consumer electronics, with the chaebol conglomerate structure remaining central to industrial output. South Korea's technology sector has grown in global importance, particularly in high-bandwidth memory (HBM) chips used in AI applications, a segment in which Korean manufacturers hold dominant market share. Real GDP growth slowed to approximately 0.9% in 2025 amid weak domestic consumption and political uncertainty, though recovery was projected for 2026. The Korea Exchange (KRX) operates the KOSPI main board and KOSDAQ market, together listing over 2,500 domestic companies with combined market capitalization exceeding $2.4 trillion as of end-2025.

外国人投資家のアクセス

Foreign investors face minimal restrictions on purchasing Korean equities. Aggregate foreign ownership ceilings were abolished in 1998. Sector-specific limits remain for industries deemed strategically sensitive, including aviation, broadcasting, and certain telecommunications services, where foreign ownership may be capped at 49% or less. As of December 2023, the requirement for foreign investors to obtain an Investment Registration Certificate (IRC) from the Financial Supervisory Service was abolished; foreigners can now trade Korean stocks using a Legal Entity Identifier (LEI) for institutional investors or a passport number for individuals. Foreign residents may open a securities trading account and a won-denominated cash account with a local custodian bank or licensed securities firm. Non-resident foreigners must transact through a local custodian arrangement. As of mid-2025, foreign investors held approximately 32.7% of KOSPI-listed stocks by market value.
