South Korea

経済・産業概況

South Korea is a high-income, export-driven economy and one of the largest in Asia, with nominal GDP of approximately $1.92 trillion as of 2024. The economy is anchored by large conglomerate groups known as chaebol, which dominate sectors including semiconductors, consumer electronics, automotive manufacturing, shipbuilding, steel, and petrochemicals. Samsung Electronics and SK Hynix together make South Korea a global leader in memory chip production, and the country has invested heavily in biotechnology, renewable energy, and defense industries. The Korea Exchange (KRX) is among the largest and most liquid equity markets in Asia, hosting over 2,400 listed companies across the KOSPI and KOSDAQ segments. South Korea is classified by MSCI as an emerging market due to ongoing restrictions on offshore Korean won trading and certain market accessibility constraints, even though it holds developed-market status under FTSE Russell's classification.

現地ブローカーアクセス

Foreign investors must register with the Financial Supervisory Service (FSS) to trade Korean securities directly, a requirement known as the Foreign Investor Registration system. Many international online brokers provide access to KRX-listed stocks via contracts for difference or direct market access, though registration requirements add administrative steps compared to more open markets. US-based investors commonly gain exposure through US-listed ETFs such as EWY or through ADRs for individual companies. Direct brokerage accounts can be opened with major Korean brokerages such as Mirae Asset Securities, Kiwoom Securities, and Samsung Securities, subject to documentation requirements.
