How the GENIUS Act Cut Stablecoin Yields to 0.38%
Two years ago, parking cash in a stablecoin could earn you 20% a year. Today, the compliant version of that same trade pays about what a checking account pays. That collapse is not an accident of the market. It is the direct result of stablecoin yield regulation under the GENIUS Act, and the fight over how far that ban should reach is still playing out in the Senate this week.
If you have been holding USDC through Coinbase, building a fintech product on stablecoin rails, or just wondering why your “crypto savings account” suddenly looks like a bank account, this is the story of how that happened, and what is still unresolved.

What actually changed for stablecoin holders
Go back to 2023 and 2024, and it was routine to see stablecoin products advertising 15%, 18%, even 20%+ annual yields. Some of that was real, some of it was Celsius and Voyager-style marketing that ended in bankruptcy. Either way, it created an expectation: stablecoins pay more than banks, full stop.
That expectation is now largely wrong, at least for the mainstream, custodial version of stablecoins that most retail users actually touch. Coinbase, the largest US on-ramp, pays roughly 3.5% to 4.7% APY on USDC through its rewards programs as of mid-2026, according to the company’s own product disclosures. Compare that to the national average savings account rate of 0.38% APY, tracked by the FDIC as of July 2026, and stablecoins still win on paper. But it is a fraction of what the marketing promised two years ago, and the gap keeps narrowing.
The GENIUS Act’s yield ban, explained
The legal root of this is the GENIUS Act, the Guiding and Establishing National Innovation for U.S. Stablecoins Act, signed into law on July 18, 2025. It is the first federal statute that creates a comprehensive regulatory framework for fiat-backed stablecoins in the United States, requiring issuers to hold reserves on at least a one to one basis in cash, short-term Treasuries, and similarly safe instruments.
Buried in that framework is one sentence that reshaped an entire industry: issuers cannot pay any form of interest or yield directly to stablecoin holders. Circle cannot pay USDC holders yield. Tether cannot pay USDT holders yield. That part of the law is not in dispute.
What is in dispute is everything downstream of it. The law does not explicitly ban an issuer’s affiliates or unrelated third parties, like an exchange, from offering their own yield-bearing products. That gap is the entire reason Coinbase can still pay USDC rewards while Circle cannot pay USDC interest. The Office of the Comptroller of the Currency tried to close that gap with a 350-plus page proposed rule released on February 25, 2026, introducing what regulators call a rebuttable presumption: if an issuer pays an affiliate who then routes money to holders, regulators will presume that arrangement violates the law unless the company can prove otherwise. The comment period on that rule closed May 1, 2026, and a final version has not been published as of this writing.
“It leaves the door open to platforms paying yield on stablecoins.” Jaret Seiberg, Policy Analyst, TD Cowen, on the OCC’s draft rule — American Banker, March 5, 2026
Where the old 20% yields actually came from
Here is the part most headlines skip: the old 20% figure rarely came from the same product regulators are now restricting. It mostly traces back to a mechanism called delta-neutral basis trading, most visibly used by Ethena’s synthetic dollar, USDe. Instead of holding cash reserves, Ethena holds crypto collateral and shorts it with futures contracts, collecting the funding-rate spread between the two positions. When funding rates spike during bull markets, that spread can blow past 20%. When markets cool off, it compresses fast, and sUSDe’s seven-day yield had fallen to roughly 3.6% by May 2026.
Because USDe is not backed one to one by fiat reserves, it does not meet the GENIUS Act’s legal definition of a payment stablecoin, and the yield ban simply does not apply to it. That is a real, still-open lane for higher yield, just one that carries derivative and counterparty risk that a simple “stablecoin yield” headline never mentions.
So two separate things collapsed at once: regulation compressed the issuer-paid channel (USDC, USDT rewards), and market normalization compressed the derivative-driven channel (Ethena, and the DeFi lending pools built on top of it). Conflating them is how you get the misleading “regulation killed all stablecoin yield” narrative.
Key insight: The GENIUS Act itself is settled law and is not changing. What is still unresolved is how far the yield ban extends to exchanges and affiliates, and that question is currently split between an unfinished OCC rule and a stalled bill in the Senate. Treat any headline claiming this is fully “resolved” with caution until the OCC publishes a final rule.
The numbers: stablecoins vs. bank savings, side by side
Here is where things actually stand as of August 2026, across every legal route to stablecoin yield:
| Route | Typical APY (Aug 2026) | Legal basis |
|---|---|---|
| National average bank savings account | 0.38% | FDIC-insured deposit |
| Best online high-yield savings accounts | 4.35% to 4.75% | FDIC-insured deposit |
| Coinbase USDC Rewards | 3.5% to 4.7% | Exchange-paid, not issuer-paid |
| Aave / Morpho stablecoin lending | 3.5% to 8.0% | Third-party DeFi lending, uncapped |
| Ethena sUSDe (synthetic dollar) | ~3.6% (down from 20%+ at cycle peaks) | Not a “payment stablecoin,” yield ban does not apply |
The takeaway is not that stablecoin yield disappeared. It is that the premium over a good online savings account has mostly disappeared for the products most retail users actually use, while the higher-risk lanes that still pay more remain legally untouched by the GENIUS Act specifically because they were built to fall outside its definitions.
The Senate fight that could rewrite all of this
This is not a closed story. The companion bill to GENIUS, the CLARITY Act, is where the real yield fight is happening now, and it is moving in real time. The bill passed the House in July 2025 and cleared the Senate Banking Committee 15 to 9 in May 2026, but stalled after Republicans balked at language that could let stablecoin issuers offer yield more broadly, something traditional banks view as a direct threat to their deposit base.
On August 6, Senate leadership confirmed there would be no full vote before the chamber’s August recess. Then, on August 8, the Senate opened its first procedural votes on the bill anyway, the furthest it has moved in months, though far short of passage. A cloture vote, if filed before recess, could come as early as September 15. If filed after senators return, it slips to September 16 at the earliest. The bill still needs roughly 10 Democratic votes to clear the 60-vote threshold, and stablecoin rewards remain one of the unresolved sticking points alongside illicit-finance protections and an ethics provision.
The bank argument doesn’t hold up to the White House’s own math
The banking industry’s case for a strict yield ban rests on a scary number: Bank of America CEO Brian Moynihan has cited Treasury estimates suggesting up to $6.6 trillion could shift out of bank deposits if yield-bearing stablecoins scale, roughly a third of all US commercial bank deposits. More than 3,200 bankers signed a letter to the Senate in January 2026 demanding the ban be extended to exchanges and affiliated platforms too.
But the White House’s own Council of Economic Advisers modeled the actual effect of a full ban, and the number is nowhere close to the industry’s warning. Under its baseline scenario, published April 8, 2026, banning stablecoin yield would increase total bank lending by only about $2.1 billion, roughly 0.02% of the $12 trillion loan market. Community bank lending would rise by about $500 million, or 0.026%. Meanwhile, the same report estimates a net consumer welfare loss of roughly $800 million a year from banning the rewards, producing a cost-benefit ratio of about 6.6 against the ban.
“Ironically, if a crypto rewards ban went into law, it would make us more profitable, since we payout large amounts in rewards to our customers holding USDC.” Brian Armstrong, CEO, Coinbase, on X, February 2026, via CoinDesk
That quote is worth sitting with. Coinbase, the company that would seemingly lose the most from a strict yield ban, has a CEO on record saying the opposite might be true, because it currently gives away nearly all of the yield it earns on customer USDC reserves. Clear Street analyst Owen Lau made a similar point about proportion: losing USDC yield-sharing “is important, but it’s not even close to existential” for Coinbase, given the company’s trading, derivatives, and Base blockchain revenue.
Our read: the loudest number in this fight, the ABA’s $6.6 trillion deposit-flight warning, is a worst-case projection, not a measured outcome, while the CEA’s $2.1 billion lending figure is an actual government model. The gap between those two numbers, three orders of magnitude apart, is the real story here, and it gets flattened every time a headline just says “banks won.”
What savers and builders should actually do now
For anyone treating a stablecoin as a bank account substitute: re-benchmark against a real high-yield savings account before assuming crypto still pays a premium. At 3.5% to 4.7% on Coinbase versus 4.35% to 4.75% at a good online bank, the “stablecoin advantage” for pure yield has nearly closed for the compliant, custodial route. Where stablecoins still clearly win is cross-border transfers and payments speed, not yield.
For developers and product teams building on stablecoin rails, the OCC’s rebuttable presumption standard is the thing to design around right now, not the CLARITY Act’s eventual outcome. Any UX pattern that looks like “yield for simply holding” carries real compliance exposure. Activity-based rewards and unaffiliated third-party lending integrations sit on much safer ground. Study Ethena’s structural workaround, a delta-neutral synthetic dollar that avoids the “payment stablecoin” definition entirely, as the clearest example of a legally distinct lane, understanding that it trades regulatory safety for real derivative and depeg risk.
Frequently asked questions
Is earning yield on stablecoins legal in the US?
Yes, but only through third parties, not directly from issuers. The GENIUS Act bans stablecoin issuers like Circle and Tether from paying yield to holders. Exchanges such as Coinbase and DeFi protocols like Aave can still pay rewards or lending returns, though the OCC is tightening rules on affiliate arrangements.
What is the GENIUS Act?
The GENIUS Act is the first US federal statute creating a comprehensive framework for fiat-backed stablecoins. It requires one to one reserves, dual state and federal supervision, and bans issuers from paying interest or yield directly to holders. It became law on July 18, 2025.
What is the average stablecoin yield in 2026?
Coinbase pays roughly 3.5% to 4.7% APY on USDC through its rewards program. DeFi lending platforms like Aave and Morpho pay 3.5% to 8% depending on utilization. Higher-risk synthetic-yield products like Ethena’s sUSDe have ranged from under 4% to over 20% at cyclical peaks.
What is the average bank savings account rate right now?
The national average savings account rate was 0.38% APY as of July 2026, according to FDIC data. Online high-yield accounts pay meaningfully more, often above 4% APY, which is why the stablecoin-versus-bank comparison depends heavily on which bank you’re actually comparing against.
Did the CLARITY Act pass?
Not as of August 9, 2026. The Senate opened its first procedural votes on the bill on August 8, 2026, but it missed the window for a full vote before the chamber’s August recess, leaving passage unlikely before mid-September at the earliest.
Why did banks push to ban stablecoin yield?
Banks argue yield-bearing stablecoins could pull deposits out of the banking system, citing Treasury estimates that up to $6.6 trillion could shift. The White House’s own Council of Economic Advisers found the actual lending benefit of a ban would be minimal, around $2.1 billion, or 0.02% of the loan market.
Where this goes next
What you now understand that most coverage of this topic misses: the “20% to bank rates” headline is really two separate stories collapsed into one. Regulation shut down issuer-paid yield specifically. Market normalization shut down the derivative-driven yields that were never regulated in the first place. Both happened at once, which made them look like a single cause.
Watch three things over the next six to eighteen months. First, whether the OCC finalizes its rebuttable presumption rule as written, which would make it the de facto standard by default if Congress keeps stalling. Second, whether the CLARITY Act actually gets its cloture vote in mid-September and what the stablecoin rewards language looks like if it survives the Banking and Agriculture committee merger. Third, whether Ethena’s non-issuer structure attracts direct regulatory attention once assets under management get large enough to matter to the same banks fighting this battle today.
