1. The Regulatory Divide: Payment vs. Yield

The global regulatory landscape for stablecoins has shifted toward a convergent prohibition model. Major jurisdictions (US, EU, Hong Kong) now legally distinguish between "payment stablecoins"—which are non-yielding and par-redeemable—and "yield-bearing tokens," which are increasingly regulated as investment products or securities. This distinction forces yield-bearing instruments to comply with rigorous securities frameworks (like MiFID II or the Howey Test) rather than simpler payment services rules.

1. The Regulatory Divide: Payment vs. Yield

The core shift in 2025–2026 is the statutory separation of transactional utility from investment return.

2. Jurisdictional Treatment of Yield-Bearing Tokens

United States: The GENIUS Act & SEC Taxonomy

• GENIUS Act (P.L. 119-27): Enacted July 18, 2025, this legislation prohibits "permitted payment stablecoin issuers" from paying any form of interest or yield to holders.
• SEC-CFTC Joint Interpretation (March 2026): This established a five-category taxonomy where payment stablecoins are excluded from the "security" definition by statute, while yield-bearing tokens remain subject to the Howey Test and are typically classified as Digital Securities.
• The "Rebuttable Presumption": An OCC rule (March 2026) assumes a violation if an issuer pays an affiliate (like an exchange) that then pays yield to users, forcing issuers to prove it isn't an evasion of the yield ban.

European Union: MiCA's Absolute Ban

• Article 22(4): Explicitly prohibits issuers and intermediaries (CASPs) from granting interest or any benefit related to holding duration for E-Money Tokens (EMTs) and Asset-Referenced Tokens (ARTs).
• Classification: Yield-bearing products (like tokenized Money Market Funds) are regulated under MiFID II, not MiCA, requiring a prospectus and investment firm licensing.

Asia-Pacific: Hong Kong vs. Singapore

• Hong Kong (Stablecoins Ordinance, Aug 2025): Imposes a complete ban on issuer-paid interest for fiat-referenced stablecoins (FRS).
• Singapore (MAS Framework): Yield is prohibited for retail users but permitted for professional investors under strict disclosure and consent requirements.

3. Market Impact and Structural Workarounds

Despite prohibitions, the yield-bearing token market has seen significant growth through specific structural vehicles:

• Tokenized RWAs: Products like BlackRock's BUIDL, which has crossed $3.0 billion in circulation [Source: https://pharos.watch/stablecoin/buidl-blackrock/], bypass stablecoin rules by registering as securities or targeting professional investors.
• Exchange Rewards: Platforms like Coinbase continue to pay "rewards" (e.g., 3.50% for Coinbase One members) funded by reserve interest sharing [Source: https://www.coinbase.com/usdc]. However, this is under increasing scrutiny as a potential regulatory workaround [Source: https://www.coindesk.com/policy/2026/03/19/coinbase-faces-a-multibillion-dollar-threat-from-d-c-but-a-rewards-loophole-could-protect-its-stablecoin-revenue].
• The "DeFi Loophole": Neither MiCA nor the GENIUS Act currently directly regulates decentralized protocols (e.g., Aave) where yield is generated at the protocol layer rather than paid by a central issuer.

4. Summary of Key Legislation (2025-2026)

The debate has effectively ended the era of "interest-paying stablecoins" as a single category. Instead, the market is bifurcating into regulated payment tools (low risk, no yield) and tokenized investment vehicles (higher compliance burden, yield-bearing).
