The problem with stablecoin regulation isn't the politics—it's that the incumbents are terrified of losing their deposit monopoly. Yesterday, the Credit Union National Association (CUNA) dropped a letter on the Senate Banking Committee that reads less like a policy suggestion and more like a panic attack from a $2.2 trillion mattress. Their target: the CLARITY Act’s “pass-through” yield provisions, which would allow stablecoin holders to earn passive rewards.

We didn’t see this coming—but we should have. The credit union lobby, representing 137 million members and over $2.2 trillion in assets, didn’t just ask for tweaks. They demanded the Senate strip out any mechanism that lets stablecoins compete with their deposit base. The message is clear: if your stablecoin behaves like a savings account but isn’t insured by the NCUA, it’s a threat. And threats get regulated.
Context: The CLARITY Act and the Yield Dilemma
The CLARITY for Payments Stablecoins Act of 2023 (H.R. 4766) is the most advanced U.S. federal framework for payment stablecoins. It passed the House Financial Services Committee in July 2023 on a party-line vote, but the Senate version—spearheaded by Senators Tillis and Alsobrooks—introduced a compromise on one explosive issue: whether stablecoin issuers can pay interest or rewards to holders.
The so-called “Tillis-Alsobrooks compromise” attempted to split the baby: stablecoins used for payments could offer “functionally passive” rewards (think: auto-compounding yield like sDAI or aUST), but not active investment products. They thought this was a reasonable middle ground. CUNA’s letter proves otherwise. The credit union system views even “passive” passive yield as an existential threat because it turns a stablecoin token into a yield-bearing product that bypasses the entire banking regulatory framework—no reserve requirements, no deposit insurance, no NCUA oversight.
Core: The Autopsy of CUNA’s Argument
Let’s dissect the letter with the forensic edge of a financial engineer who’s seen this movie before. CUNA’s core grievance isn’t about consumer protection—it’s about capital flight. They cite data showing that from 2022 to 2024, the aggregate deposit base of federally insured credit unions grew a paltry 3.2%, while the total market cap of yield-bearing stablecoins—like USDC Yield, DSR sDAI, and protocols on Aave or Compound—exploded 240% to roughly $15 billion.
The hidden assumption here is brutal: credit unions are losing the savings account war to a technology stack that offers 4-8% APY with global accessibility and zero bank holidays. And they know their own product can’t compete. The average credit union savings account pays 0.23% APY. That’s not a typo. So, they’re not asking for a level playing field—they’re asking for the game to be banned.
CUNA’s technical objection centers on the word “functionally passive.” They argue that any reward—even if algorithmically distributed without human intervention—creates an expectation of profit, thus meeting the Howey test’s third prong (expectation of profits from the efforts of others). This transforms a stablecoin from a payment instrument into a security. They’re right on the law, but wrong on the economics. The entire DeFi ecosystem lives in the gap between “payment” and “investment.” If you close that gap, you don’t just kill yield stablecoins—you kill the compounding engine that powers 80% of DeFi liquidity.

Data-backed structural risk: Let’s run a stress test. Suppose the CLARITY Act passes with CUNA’s desired language, prohibiting any “pass-through” yield. The immediate impact: the $15 billion in yield-bearing stablecoin TVL (USDC Yield, sDAI, FRAX, etc.) would need to either stop offering rewards or move entirely offshore. The larger contagion: every DeFi protocol that relies on stablecoin deposits as a yield source—lending markets, automated market makers, yield aggregators—would face a sudden withdrawal of low-cost liquidity. We’re not talking about a rug pull; we’re talking about a liquidity desertification.
But here’s the part nobody is discussing: the credit union’s own evolution. NCUA board member Rodney Hood, a former Chairman, recently said credit unions must embrace “modernization” or die. His words, not mine. The irony is thick—they’re fighting to preserve a business model that earns spreads on deposits that cost near zero, while simultaneously acknowledging they need to evolve. Yet their lobbying strategy is to use regulation to kill the competition rather than innovate.
Contrarian Angle: What CUNA Didn’t Tell You
The conventional take is that CUNA is protecting consumers from unregulated stablecoin Ponzi risks. I call bullshit. The real story is about regulatory capture and the slow death of the fractional reserve deposit model. Credit unions can afford to pay 0.23% because they lend at 5-7%. Stablecoin yield doesn’t need that spread—it’s sourced from protocol revenue (trading fees, liquidation penalties) or algorithmic inflation (like DSR’s DAI minting subsidy). Both are fragile, but the former is sustainable; the latter is a form of Ponzi that Terra proved fatal.
Here’s the contrarian insight: CUNA is terrified of the wrong thing. The real drain isn’t yield-bearing stablecoins—it’s non-yield stablecoins like USDC and USDT that are already eating cross-border payments and remittances. The yield is just an accelerant. But by attacking the yield, they’re signaling that they view any stablecoin that competes with deposits as an enemy. This sets up a dangerous binary: either stablecoins stay as sterile payment rails (like FedNow with a private label), or they become fully functional money lego blocks. There is no middle ground.
And let’s talk about the elephant in the room: the “s evolution of stablecoins” is already happening without permission. Everyday, $2 billion+ in USDC moves across DeFi to earn yield. The cat is out of the bag. If the Senate bans pass-through yield, two things happen: (1) yield protocols fork to non-U.S. jurisdictional wrappers (think XDC Network or Solana’s Pyth-based stablecoins), and (2) the U.S. loses the stablecoin innovation race to Europe under MiCA, where yield is not explicitly banned.
Takeaway: The Next Watch
The Senate Banking Committee markup of the CLARITY Act is expected in late October 2024. Watch for three things: the exact wording of “pass-through yield” exception, any amendments from Senator Warren (who is a known stablecoin skeptic), and whether the credit union lobby teams up with the American Bankers Association to form a united front. If they do, the odds of yield being entirely stripped from stablecoins jump to above 90%.
