RWA & STO Regulatory Frameworks: Korea Capital Markets Act vs US SEC Securities Laws

Published: August 28, 2026 • 12 min read

1. Core Philosophy: Technology-Neutral Regulation

The golden rule adopted by financial authorities across both the US (SEC) and South Korea (FSC) is Technology Neutrality:

"Form does not alter substance. Issuing a security in the form of an ERC-20 token on a blockchain does not exempt it from securities regulations."

— Regulatory consensus across SEC (US) & FSC (Korea)

Traditional securities exist in physical paper certificate format or centralized electronic book-entry format. Token securities (STO) are simply a third form of issuance container using a distributed ledger. The underlying rights (voting, revenue share, claims on liquidation) remain subject to existing capital markets law.

2. US SEC Framework: Howey Test & Private Placement Exemptions

Under the US Securities Act of 1933, any offering of securities must either be registered with the SEC (a costly and lengthy IPO process via Form S-1) or qualify for a specific registration exemption.

The Howey Test: Defining an Investment Contract

Established in SEC v. W.J. Howey Co. (1946), a digital asset is deemed a security (specifically an investment contract) if it meets 4 prongs:

Prong 1
Investment of Money
Capital committal including fiat or cryptocurrency.
Prong 2
Common Enterprise
Pooling of investor funds or tied financial fortunes.
Prong 3
Expectation of Profits
Dividends, interest, periodic yields, or capital gains.
Prong 4
Efforts of Others
Returns depend on efforts of promoter or third-party manager.

US Registration Exemptions Used by RWA Protocols

Exemption Capital Limit Investor Requirements Key Characteristic
Regulation D (Rule 506c) Unlimited Accredited Investors Only (verified) Primary route for US RWA issuers (e.g., Ondo OUSG, Centrifuge pools)
Regulation S Unlimited Non-US Persons Only (Offshore) Used for global distribution outside US borders (e.g., Ondo USDY)
Regulation A+ Up to $75M / year Retail + Accredited (Mini-IPO) Requires SEC circular qualification; allows general public investment

3. Korea FSC Framework: Token Securities Guidelines

In February 2023, the Korean Financial Services Commission (FSC) issued the Guidelines on the Issuance and Distribution of Token Securities (ST). The framework creates a formal legal path for non-standard assets to be fractionalized and registered using distributed ledgers.

Two Primary Security Types Governed under Korean STO

1. Trust Beneficiary Certificates

Trust beneficiary rights based on tangible underlying assets (e.g., real estate rental income trusts, infrastructure cash flows).

2. Investment Contract Securities

Contracts where investors pool capital for a common business managed by a third party, claiming profit sharing (e.g., fractional fine art, music copyright IP).

4. Structural Separation: Issuer vs Account Manager vs OTC Market

The cornerstone of Korea's STO structure is the Issuance-Distribution Separation Principle, designed to prevent conflict of interest and price manipulation:

Role 1: Creation

Issuer Registry Entity

Qualifying entities meeting capital, staffing, and technical criteria can directly record and issue token securities onto a distributed ledger without going through a broker.

E.g., Licensed Fractional Platforms, Asset Originators
Role 2: Custody & Trust

Account Manager

Securities broker-dealers and banks that maintain underlying fiat accounts, manage investor ledgers, and handle investor identity verification (KYC/AML).

E.g., Securities Broker-Dealers & Custodian Banks
Role 3: Secondary Market

OTC Brokerage Platform

Licensed ATS or multilateral trading facilities authorized to broker secondary market trades for unlisted token securities.

E.g., Authorized ATS & Multilateral Trading Venues
Why Separation is Mandatory: An entity that originates and issues an asset (e.g., a real estate fractional platform) cannot operate the secondary exchange where those same tokens are priced and traded, preventing wash trading and self-dealing.

5. Legal Requirements for Distributed Ledgers as Electronic Registries

Under the amendment to the Electronic Securities Act, not every blockchain qualifies as a legally recognized electronic registry. The distributed ledger must satisfy strict operational prerequisites:

1. Node Diversity & Quorum

Nodes must be distributed across multiple independent legal entities (e.g., at least 51% controlled by unaffiliated institutions) to prevent unilateral state tampering.

2. Immediate Finality & Error Recovery

Consensus mechanisms must guarantee deterministic finality (IBFT/PBFT) without probabilistic chain reorganization, and must support administrative state rollback in case of court orders.

3. PII & Privacy Compliance

Personal Identifiable Information (PII) must not be stored in cleartext on-chain to comply with data protection laws (GDPR, Korea PIPA); off-chain zero-knowledge or DID architectures are required.

4. Native Token Decoupling

Network transaction fees (Gas) must not be dependent on volatile speculative native cryptocurrency tokens, favoring permissioned enterprise networks with fixed fiat/sponsored gas models.

6. US vs Korea Regulatory Comparison Matrix

Aspect United States (SEC) South Korea (FSC)
Governing Statute Securities Act of 1933 & 1934 Capital Markets Act & Electronic Securities Act
Primary Strategy Private placement exemptions (Reg D 506c, Reg S) Regulatory Sandbox & Formal Statutory Amendment
Investor Accessibility Heavily restricted to Accredited Investors Retail access allowed with strict annual investment limits
Infrastructure Preference Pragmatic public mainnets (Ethereum, Solana) with ERC-3643 whitelist Permissioned Consortium Chains (Besu, Quorum) tied to Securities firms
