South Korea's Tokenized Stock Classification:

Overview

South Korea has established a comprehensive regulatory framework for tokenized securities through amendments to the Capital Markets Act and Electronic Securities Act, passed by the National Assembly on January 15, 2026, with full implementation scheduled for February 4, 2027.

Binary Classification System

South Korea operates a dual-track classification system for digital assets:

Digital assets are classified as securities if they meet the Howey Test criteria:

• Provide a stake in business operations
• Grant access to profits from a business
• Offer rights to dividends or residual property ownership

The Ministry of Economy and Finance has stated that "although tokenized stocks are issued as tokens on a blockchain, they are fundamentally securities because they represent the economic rights of actual shares."

Key Regulatory Requirements for Security Tokens

For Issuers:

• Must register with Korea Securities Depository (KSD)
• Must comply with standardized disclosure requirements
• Must follow legally mandated procedures for electronic registration

For Intermediaries:

• Brokerages and trading platforms must register before facilitating transactions
• Over-the-counter brokerage license required under FSCMA
• Trading must occur through licensed financial institutions

Technical Requirements (Critical for DeFi):

Implications for DeFi Projects

Challenges

1. No Decentralization Exemption: The FSC has not considered the decentralized nature of blockchain ecosystems when preparing Token Security Guidelines. The framework does not provide a clear "decentralization exemption."

2. Node Requirements Conflict: The >51% node requirement by unrelated parties directly conflicts with fully decentralized protocols that operate on public blockchains.

3. Licensing Requirements: DeFi protocols facilitating security tokens may need:

   • VASP licensing under VAUPA (for non-security tokens)
   • Over-the-counter brokerage license under FSCMA (for security tokens)

4. Trading Venue Restrictions: Crypto exchanges cannot legally list security tokens — they must delist and move to licensed securities trading venues.

5. VAUPA Scope Limitations: The Virtual Asset User Protection Act focuses only on VASPs' asset segregation and prohibition of unfair trading activities, and does not explicitly regulate:

   • Smart contract-based services
   • Decentralized Autonomous Organizations (DAOs)
   • Web3.0 protocols

Regulatory Gaps

The current framework has significant gaps for DeFi:

• DeFi protocols are not contemplated in current regulations
• No clear guidance on how "decentralized" a protocol must be to avoid regulation
• Cross-border digital asset transactions lack clear rules
• Areas requiring further legislative refinement include: stablecoin regulation, DeFi protocols, NFTs, and international harmonization

Potential Opportunities

1. RWA Integration: DeFi protocols can potentially integrate with regulated tokenized securities
2. Institutional Onboarding: Clear framework may attract traditional finance into DeFi
3. Collateral Use: Tokenized securities could serve as collateral within DeFi ecosystems
4. Licensed Intermediary Partnerships: Projects can operate within the framework by partnering with licensed entities

Implementation Timeline

A Public-Private Council has been established with representatives from FSC, FSS, KSD, Korea Financial Investment Association, and industry participants to oversee implementation across three working divisions: Technology/Infrastructure, Issuance Regulations, and Circulation Regulations.

Strategic Considerations for DeFi Projects

Near-Term (2025-2026):

1. Assess whether any protocol tokens or offered assets qualify as securities under FSC guidelines
2. Monitor July 2026 detailed rules for critical implementation details
3. Evaluate taxation impact — securities classification triggers taxation as early as H2 2026
4. Identify required licenses (VASP, brokerage) for planned activities

Medium-Term (2027+):

1. Ensure smart contract functionality meets node requirements (>51% non-related participants)
2. Establish relationships with licensed brokerages for security token offerings
3. Consider tokenizing real-world assets under the new framework
4. Leverage Busan Digital Asset Nexus for sandbox experimentation

---

Bottom Line

South Korea is creating a comprehensive framework that brings tokenized securities into the regulated financial system while leaving DeFi in a regulatory gray area. The classification of tokenized stocks as securities will require DeFi projects interacting with them to navigate licensing requirements, though truly decentralized protocols without profit-seeking may avoid direct regulation. The 51% node requirement and prohibition on crypto-asset fee settlement create structural barriers for fully decentralized protocols operating on public blockchains.

Evidence Status

What Remains Open

• Verification of the specific legislative dates and implementation details from primary sources (National Assembly records, FSC announcements)
• Whether the July 2026 detailed rules will include any DeFi-specific provisions or carve-outs
• How cross-border DeFi protocols will be treated under the framework
• Whether the 51% node requirement will be enforced on existing public blockchain networks

---

Suggested Next Steps

1. Monitor July 2026 detailed rules announcement — this will clarify critical implementation details for DeFi projects, particularly around node requirements and decentralization thresholds. Set a calendar reminder or schedule a research task to review the published rules.

2. Conduct a protocol audit — assess whether any existing or planned protocol tokens or offered assets would qualify as securities under the FSC's Howey Test criteria, and identify required licensing pathways before the February 2027 implementation date.
