The Stablecoin Yield Fight Has a Winner Already. It Is Not DeFi.

The proposed Crypto Clarity Act would ban yield and reward payments on stablecoins issued by entities that are not banks. That sentence sounds technical. It is not. It determines whether a $200 billion asset class continues to function as an investment product in the US, or gets restructured into pure payments infrastructure with the yield flowing to chartered banks instead of DeFi protocols and their users.

Key Highlights

• The Senate’s market structure bill includes a provision banning yield payments on stablecoins issued by nonbank entities in the US
• The ban would directly affect Sky’s DAI Savings Rate (currently around 4.5%), Ethena’s USDe delta neutral yield, and any USDC or USDT yield wrapper built on DeFi protocols
• Circle and Tether are largely unaffected: neither pays yield directly to stablecoin holders, keeping treasury income internal
• DeFi protocols built on top of those stablecoins face compliance restructuring or geofencing of US users if the ban passes
• Senate Banking Committee Chair Tim Scott has not yet scheduled a markup date. The yield ban remains one of three unresolved sticking points alongside DeFi liability and trading platform definitions.
• The banking lobby argues nonbank stablecoin yield is deposit competition without FDIC insurance, capital requirements, or Fed oversight

What the ban actually covers

Sky’s DAI Savings Rate currently pays around 4.5% to DAI holders who deposit into the DSR contract. Ethena’s USDe advertises yield derived from perpetual funding rates. USDC and USDT wrapper protocols on Aave, Compound, and Morpho Blue offer similar economics. Under the proposed language, each of these would need to restructure for US users, geofence Americans from the product, or shut down domestic access entirely.

Circle and Tether would survive unchanged. Circle earns yield on its Treasury reserves internally and does not pass it to USDC holders. Same structure for Tether. The ban targets what has been built on top of their stablecoins, not the stablecoins themselves. The two largest stablecoin issuers are fine. The DeFi ecosystem that built the yield layer above them is the one facing restructuring.

Who is driving this and why

JPMorgan, Bank of America, and the broader banking lobby have made the deposit competition argument clearly in Senate testimony. A nonbank entity that issues a token, backs it with Treasuries, and pays 4% to holders is doing economically what a bank does without a single regulatory constraint that applies to banks. No FDIC insurance. No Fed supervision. No capital adequacy standards. No resolution framework if the issuer fails.

The banking lobby is not wrong on the facts. A yield bearing stablecoin is economically similar to a deposit. The question is whether the solution is to require stablecoin issuers to meet bank standards, a compliance approach, or to ban the yield entirely, a prohibition approach. The Senate draft chose prohibition. That policy choice is what the DeFi industry is contesting, not the underlying concern about deposit competition.

The 100-plus crypto firms pushing for CLARITY Act passage have focused their public arguments on market structure, not the stablecoin yield provision specifically. That is a deliberate choice. The market structure framework has broader support. The yield ban is the most contentious piece and the industry coalition is trying to prevent it from becoming the headline that kills the whole bill.

The DeFi counter-argument

Several protocol teams argue that yield on stablecoins is not categorically different from a money market fund. Both pay returns on short duration instruments. Money market funds are regulated but legal. The risk profile of a stablecoin yield product, when properly disclosed, may not be meaningfully riskier than a Fidelity money market fund.

That argument is coherent. It is also losing in the Senate. The banking lobby has more votes than DeFi has lobbyists, and the deposit competition framing has landed effectively with Senate Banking Committee members who have deep bank industry ties. Coherent arguments and winning arguments are different things in Washington.

What actually happens if the ban passes

The most likely outcome is not compliance. Sky would geofence US users from the DAI Savings Rate. Ethena would geofence Americans from USDe yield. The products continue globally. US users find VPNs. The yield market does not disappear. It becomes less accessible to Americans and less regulated in practice than it would be under a disclosure-based framework that required reserve transparency and clear redemption rights.

That outcome helps chartered banks. It does not protect American consumers from anything. It also pushes stablecoin yield activity toward jurisdictions with clearer frameworks. The Hong Kong Web3 Festival this week featured multiple sessions on stablecoin infrastructure precisely because Hong Kong’s framework is more explicit on what is permitted. Capital and development talent follow regulatory clarity. A yield ban accelerates that migration and does nothing to stop US consumers from accessing offshore products.

The working compromise that might survive committee

Senate negotiators are reportedly circling a tiered framework: yield below a specified threshold is permitted for stablecoin issuers registered under the new regulatory structure. Nobody loves it. The threshold number has not leaked publicly. The DeFi industry would accept modest restrictions if it meant legal certainty in the US market. The banking lobby would accept a threshold if it is low enough that only their deposit rates beat it comfortably.

That is the deal that might actually clear committee. Tim Scott has not scheduled a markup. Until he does, nothing is final. The July deadline for the overall market structure bill applies here too: if the yield provision is not resolved in committee by summer, this slips into 2027 and the entire DeFi industry spends another year operating under enforcement discretion rather than statute.

The TCB View

A blanket yield prohibition is not consumer protection. It is regulatory capture dressed up as safety. The actual risk to stablecoin holders is not whether they receive yield. It is whether the stablecoin is properly backed and redeemable on demand. Require reserve transparency and redemption rights, and you have addressed the genuine risk. A yield ban redirects income that was going to DeFi protocol users into banks that will offer it as a savings product under a different name with a lower rate. Congress should regulate the backing and the redemption, not the yield. It probably will not.
