U.S. stablecoin policy is converging on one core question: should a payment stablecoin be allowed to deliver interest-like yield to the person holding it?
The answer will determine whether stablecoins remain mainly a faster payments and settlement rail, or shift into a mass-market deposit substitute distributed through exchanges and fintech apps.
The current U.S. framework is designed to keep regulated stablecoins in the payments category. The GENIUS Act includes a direct prohibition on issuer paid interest or yield to stablecoin holders.
At the same time, legal and market commentary has emphasized a gray area: third party or affiliate rewards that can feel like yield even if the issuer is not technically paying it.
That boundary is where crypto banking starts to look like banking, and it is why the yield rule has become a central political and economic battleground in early 2026.
Key Takeaways
- The GENIUS Act bans issuer paid interest or yield to stablecoin holders.
- Policy debate is focused on platform rewards that can mimic yield.
- Stablecoins are large enough that yield rules can move real money: market cap was about $307.29B on February 10, 2026.
- Banks warn of deposit outflows; estimates range up to $500B by 2028 in one major bank analysis, with higher figures in advocacy research.
- A likely compromise is no passive yield on idle balances, with possible room for activity based rewards.
What The GENIUS Act Does On Yield
The GENIUS Act contains a clear rule: no permitted payment stablecoin issuer may pay the holder any form of interest or yield solely in connection with holding, using, or retaining the stablecoin.
The intent is to keep stablecoins positioned as payment instruments rather than savings products that compete directly with bank deposits.
The U.S. Senate Banking Committee majority has described this as a deliberate separation between payments products and banking products.
A critical nuance is how the law interacts with distribution. Legal analysis notes the Act bans issuer paid yield but does not explicitly prohibit third party or affiliate arrangements that offer interest bearing products.
This is why rewards offered by platforms such as Coinbase have become the policy flashpoint.
The Market Context: Stablecoins Are Now Systemically Relevant
The stablecoin market is no longer small enough for yield policy to be theoretical.
- Global stablecoin market cap was $307.29B on February 10, 2026, per MacroMicro.
- Reporting and research continue to emphasize concentration in USD linked coins and large issuers, which amplifies the impact of any yield rule on consumer behavior and bank funding.
There is also a major debate about real world usage. J.P.Morgan argued in mid 2025 that only about 6% of stablecoin demand was tied to payments at that time, with most usage linked to trading, DeFi, and collateral, and it cut aggressive market growth forecasts accordingly.
That argument matters because policymakers are more willing to ban yield when they view stablecoins as trading infrastructure rather than everyday money.
Issuer Economics: Yield Exists, The Question Is Who Captures It
Even when users do not receive yield, stablecoin reserve portfolios generate it.
For example, reserve composition disclosures and analysis for Circle and USDC have highlighted a heavy allocation to short duration government linked instruments such as Treasury bills and reverse repos (Grant Thornton).
This creates an unavoidable distribution question:
- If the issuer cannot pay yield to holders, reserve income flows to the issuer and its partners
- Platforms may use some of that economic value to fund rewards
- Banks may benefit if reserves sit as deposits at banks, but the user still may feel underpaid relative to risk free rates
That gap between risk free yields and what users receive is what makes platform rewards politically explosive.
Why Yield Is The Crypto Banking Switch
Yield turns stablecoins from a payments rail into a banking competitor because it completes the consumer bundle:
- store value
- move value
- earn return
When stablecoins deliver a competitive return, they start to resemble a high yield transaction account that can be held and used inside a wallet app, potentially at global scale.
Banks and trade groups argue that allowing passive yield creates shadow deposits, pulling balances out of banks without funding long term credit creation.
The concern is not only deposit outflow, but also a change in the structure of financial intermediation, since stablecoin reserves recycle into Treasuries and very short duration assets rather than bank loan books.
Deposit Flight: The Numbers And Why They Diverge
Deposit flight estimates vary widely because they depend on assumptions about consumer price sensitivity, bank response, and product design.
Moderate to high end estimates in major reporting
A Reuters report on Standard Chartered analysis stated U.S. banks could lose up to $500B in deposits to stablecoins by 2028, with regional lenders most exposed.
Advocacy and trade group framing
Some banking industry commentary argues the risk could be substantially larger under scenarios where stablecoin rewards become widespread and competitive with policy rates, and they call for closing loopholes that enable passive yield through intermediaries.
Why estimates disagree
The spread is driven by a few key variables:
- Passive yield vs activity based rewards
- How quickly banks raise deposit rates to defend balances
- Whether users hold stablecoins directly or through bank distributed wrappers
- Whether stablecoin reserves remain as deposits inside the banking system, which can mitigate but not eliminate credit impacts
Credit And Lending: The Real Economy Channel
Policymakers care about deposits because deposits fund lending. If meaningful balances shift from banks into stablecoins, the system can replace cheap retail deposits with more expensive wholesale funding, which can raise loan rates and constrain credit availability.
This is a central claim in bank oriented analysis that frames yield bearing stablecoins as a threat to Main Street lending.
The counterargument, reflected in parts of the public debate, is that the system can adapt and that competitive pressure may simply force banks to pay consumers more fairly while still maintaining profitability.
Both can be true depending on the segment:
- larger banks may adapt more easily
- smaller and regional banks may face sharper pressure if they rely on rate sensitive deposits
Policy In Motion: White House Talks And Negotiation Principles
In early February 2026, reporting described a White House meeting that failed to resolve a legislative stalemate, with stablecoin rewards and yield treatment a key fault line between banks and crypto firms.
Around the same time, Politico reported that banks circulated principles for stablecoin yield negotiations, reinforcing their push to limit deposit like competition through broad restrictions on rewards.
More recent coverage indicates talks continued in mid February 2026 with incremental progress but no final agreement.
Three Scenarios For How Crypto Banking Changes
Scenario A: Platform rewards persist and function like yield
If platform rewards remain broadly allowed, stablecoin balances inside exchanges and wallets can behave like interest bearing accounts.
That accelerates deposit competition and pushes banks to respond by raising rates, offering their own stablecoin products, or partnering with issuers.
Scenario B: Passive yield is banned everywhere, including indirect rewards
If rules close the rewards pathway, stablecoins grow more as settlement and payments infrastructure than as savings vehicles.
Users seeking yield move toward explicit investment wrappers or DeFi, while stablecoins remain primarily money like and neutral.
Scenario C: Compromise regime with no yield on idle balances, rewards tied to activity
This is the most structurally important middle ground. It prevents stablecoins from becoming pure deposit substitutes but still enables consumer incentives for usage, such as transaction linked rewards.
It also forces platforms to prove real payment utility, not just balance accumulation.
Winners, Losers, And Second Order Effects
Likely winners
- large distribution platforms that control wallets and user experience
- consumers if competition improves returns and reduces payment friction
- the Treasury market if stablecoin growth increases demand for short duration government paper
Likely losers
- smaller banks and regional lenders if funding costs rise faster than their ability to reprice loans
- sectors dependent on relationship lending if local deposit bases shrink meaningfully
Second order effects to watch
- product design will shift toward compliance safe reward structures
- stablecoin adoption metrics will be scrutinized for real payments share, not raw on chain volume
What To Watch Next
- Final legislative language on rewards and indirect yield, including anti evasion rules
- Whether banks distribute stablecoins to retain customer relationships, or whether exchanges dominate wallet distribution
- How stablecoin growth forecasts evolve as payments usage becomes the key proof point
Conclusion
The GENIUS Act yield prohibition is not a minor product constraint. It is a deliberate line between stablecoins as payment instruments and stablecoins as deposit substitutes.
- If regulators allow passive yield through platforms, crypto banking becomes a direct competitor to bank deposits at scale.
- If they close the loophole, stablecoins still expand, but more as settlement infrastructure than as a mass market savings product.
The most realistic outcome is a compromise that bans idle balance yield while allowing activity linked rewards, which would reshape how every major platform designs stablecoin products in 2026.

FAQs:
1) What does the GENIUS Act prohibit on stablecoin yield?
The GENIUS Act prohibits a permitted payment stablecoin issuer from paying any form of interest or yield to a holder solely for holding, using, or retaining the stablecoin.
2) Why are platform rewards controversial if the issuer is not paying yield?
Legal analysis notes the Act bans issuer paid yield but does not explicitly prohibit third party or affiliate arrangements that can mimic yield economics. That is why policymakers debate whether platform rewards undermine the intent of the rule.
3) How big is the stablecoin market right now?
A commonly cited data series placed global stablecoin market cap at about $307.29B on February 10, 2026.
4) How much bank deposit outflow is realistically at risk?
Estimates vary widely. One major bank analysis reported by Reuters warns of up to $500B in deposit outflows by 2028, while other analyses argue impacts could be smaller under slower adoption or weaker reward structures.
5) Would banning passive yield stop stablecoin growth?
Not necessarily. It likely shifts growth toward payments, settlement, and cross border use cases while pushing yield seeking behavior into separate investment products or DeFi rather than idle stablecoin balances.
