Banking Law in South Korea
Introduction
South Korean banking law is structured around a dual regulatory framework: the Financial Services Commission (FSC) (금융위원회) sets policy and regulation, while the Financial Supervisory Service (FSS) (금융감독원) conducts on-site examinations and enforcement. The Banking Act (은행법) serves as the primary legislative instrument, supplemented by the Capital Markets and Financial Investment Business Act (FISCMA) and the Act on the Establishment of Financial Services Commission. South Korea’s banking sector has undergone significant transformation since the 1997 Asian Financial Crisis, shifting from a government-directed banking system to a market-oriented one.
Banking Act
The Banking Act (enacted 1950, comprehensively amended 2000 and 2016) governs the establishment, operation, and supervision of banks. Key provisions include:
Licensing and Ownership
Banking business requires an FSC license. Ownership restrictions include a 10% ceiling on non-financial business groups’ equity holdings in commercial banks, reflecting post-crisis measures to prevent chaebol domination of the banking sector.
Prudential Regulation
The Act imposes capital adequacy requirements (Basel III standards), large credit exposure limits (25% of capital base), and restrictions on foreign currency exposure. The FSS conducts regular inspections.
Corporate Governance
Banks must maintain independent boards, risk management committees, and internal audit functions. The Act requires approval for major shareholders and mandates separation of banking and commerce.
Financial Services Commission (FSC)
The FSC, established in 2008 by consolidating financial regulatory functions, is a central administrative agency under the Prime Minister’s Office. Its responsibilities include:
- Licensing financial institutions
- Issuing regulations and supervisory decrees
- Approving mergers and acquisitions in the financial sector
- International financial negotiations
Digital Banking
South Korea has embraced digital banking innovation:
- Internet-only banks (KakaoBank, K-Bank, Toss Bank) operate under specialized FSC guidelines
- MyData business (Personal Data Usage Act) allows banks to use customer data with consent
- Open banking framework since 2019 enables third-party payment initiation services
Capital Markets and Banking Convergence
The Financial Investment Services and Capital Markets Act (FISCMA) governs securities firms, asset management, and derivatives, creating a comprehensive capital market regime that interacts with traditional banking regulation. Universal banking is limited, with commercial banking separated from investment banking.
Conclusion
South Korean banking law balances financial stability with innovation, reflecting lessons from the 1997 crisis and more recent household debt concerns. The FSC-FSS dual regulatory structure provides consolidated oversight, while digital banking reforms position Korea as a fintech-friendly jurisdiction.
