The Crypto Clarity Act Would Ban Stablecoin Yield. The Industry Is Right to Worry

A provision buried in the Crypto Clarity Act, the most significant piece of US digital asset legislation in three years, would prohibit payment stablecoin issuers from offering yield or rewards to holders. The clause is aimed at preventing stablecoins from functioning as unregistered securities. But its practical effect would reach far beyond retail savings accounts and into the core economics of decentralized finance.

What the Bill Actually Says

Section 14(c) of the Crypto Clarity Act states that a permitted payment stablecoin issuer “shall not pay interest, yield, or any other return” to stablecoin holders. The language is broad. It covers direct yield products and, depending on interpretation, could extend to any protocol that uses a compliant stablecoin as collateral to generate returns for depositors.

The bill defines a “payment stablecoin” as any digital asset that is designed to maintain a stable value relative to the US dollar and is used primarily for payments or transfers. That definition captures virtually every major stablecoin currently in circulation, including USDC and USDT.

Why DeFi Is the Real Target

Aave, Compound, and Curve all offer yield on stablecoin deposits that ranges from 3 to 8 percent annually, depending on market conditions. That yield comes from lending fees paid by borrowers. The stablecoin issuers themselves are not paying yield. But under the broadest reading of the proposed ban, protocols that accept compliant stablecoins and pay returns on them could be seen as structuring transactions that the issuer is prohibited from enabling.

The legal risk is not that Aave would be shut down, but that USDC and USDT could be prohibited from being used in yield-bearing protocols if their issuers face liability for enabling those flows. Circle’s legal team flagged this interpretation in its February 2026 comment letter, arguing that the yield ban should apply only to direct issuer distributions, not third-party protocol activity.

The Offshore Response

If yield-bearing stablecoins become legally untenable in the US, the activity does not disappear. It moves to jurisdictions that permit it. The EU’s MiCA framework explicitly allows interest-bearing stablecoins under certain conditions. Hong Kong’s stablecoin regime, finalized in January 2026, places no yield restrictions on non-systemically important issuers. A yield ban in the US without coordinated international standards creates regulatory arbitrage that benefits non-US issuers and exchanges.

The TCB View

The concern driving the yield ban is legitimate. Yield-bearing stablecoins that compete with bank deposits represent a real challenge to the financial system’s deposit base, and regulators are right to want guardrails. But the current language in the Crypto Clarity Act is blunt where it needs to be precise. A blanket prohibition on yield does not distinguish between a stablecoin issuer acting as a shadow bank and a DeFi protocol paying lending fees. Congress needs to draw that line explicitly, or the most innovative part of the ecosystem will simply move to where the line does not exist.
