The biggest fight in American finance right now is over a single clause: whether digital dollars can pay their holders interest. Banks say yield-bearing stablecoins would drain trillions in deposits and break the lending machine. Crypto says the banks are defending a monopoly on other people’s money. The CLARITY Act is hostage to the answer, and this week the standoff escalated on every front.
Summary
- A battle over whether stablecoins should pay interest has become the biggest obstacle to advancing the CLARITY Act in the US Senate.
- Banks warn that yield bearing stablecoins could pull trillions of dollars from deposits while the crypto industry argues savers should receive the returns generated by reserve assets.
- As lawmakers remain divided, banks are also preparing for a future with stablecoins by investing in digital dollar infrastructure and settlement networks.
The week of June 29, 2026, was supposed to move the CLARITY Act toward the Senate floor. Instead, Coinbase publicly pulled its support for the bill it had spent two years championing, Senate Banking Committee chairman Tim Scott postponed the markup, and President Trump posted that the banks lobbying against stablecoin yield were threatening and undermining his own signature crypto law. The proximate cause of all three events was the same unresolved question: can a stablecoin pay interest?
The question sounds technical. It is not. It is a fight over roughly $6 trillion, which is the amount of deposit money that Bank of America chief executive Brian Moynihan has warned could migrate out of the banking system if digital dollars are allowed to pass their reserve earnings to holders. Behind the number sits the basic architecture of American credit: banks fund loans with deposits that pay savers little, and anything that gives savers a better default option attacks the cheapest funding source in finance.
Both sides understand the stakes with total clarity, which is why neither will yield. The banks have the oldest lobby in Washington and a century of regulatory capture to draw on. Crypto has the GENIUS Act already signed, a president publicly on its side, and products that customers demonstrably want. Between them sits a Congress trying to pass a market structure bill that both industries claim to support and each is willing to kill over this clause.
This is the anatomy of the standoff: where the yield actually comes from, what each side’s studies really say, how the fight broke into the open at Davos, why the CLARITY Act is stalled, and what the banks are quietly building in case they lose.
Where stablecoin yield comes from
A dollar stablecoin is a bearer claim on a reserve. The issuer takes a customer dollar, parks it in Treasury bills and repo and cash equivalents, and gives back a token redeemable at par. At 2026 short-term rates, that reserve portfolio throws off meaningful income: roughly four cents per year on every dollar, paid by the United States government to the issuer.
Under the GENIUS Act, the stablecoin framework signed in 2025, issuers keep that income. The law prohibits payment stablecoins from paying interest or yield to holders, a clause the banking lobby fought for and won. The result is one of the stranger economic arrangements in modern finance: tens of millions of stablecoin holders collectively finance a float measured in hundreds of billions of dollars, and the entire risk-free return on that float accrues to issuers and their distribution partners.
Tether’s profits, Circle’s revenue-sharing arrangement with Coinbase, and the business case for every new entrant described in the consortium stablecoin model behind Open USD all rest on that captured spread.
Crypto’s position is that the arrangement is indefensible on its own terms. If the token holder supplies the dollar, the token holder should be able to receive the yield, the same way a money market fund passes through its portfolio income. Exchanges already approximate this with rewards programs that pay users for holding certain stablecoins, a workaround the banks call interest by another name and want closed.
The banks’ position is that the arrangement is the only thing standing between the deposit system and a slow-motion run. A stablecoin that pays four percent, holds only Treasuries, settles instantly, and lives in a phone app is not a payment instrument, in their telling. It is a narrow bank, the exact institution American regulators have refused to charter for a century, because a narrow bank collects deposits and funds nothing.
Both descriptions are accurate. That is what makes the fight so hard to resolve. A product can be, simultaneously, a long-overdue transfer of interest income to the people who supply the money and a structural threat to the funding model of every lender in the country. The legislative machinery now stuck in the Senate exists precisely because Congress must pick which description governs, and there is no compromise text that makes both true halves false.
The dueling studies: $6.6 trillion or $2.1 billion
In early 2026 the American Bankers Association put a number on the threat. Its analysis warned that permitting interest-bearing stablecoins could trigger as much as $6.6 trillion in deposit flight from the banking system, a figure that would represent a structural repricing of bank funding. Moynihan carried the message personally, telling audiences that 30 to 35 percent of transactional deposits could leave banks if yield-bearing digital dollars became legal, and putting the Bank of America estimate in the $6 trillion range.
The mechanism behind the number is credit contraction. Deposits fund loans. A dollar that leaves a checking account for a stablecoin backed by T-bills stops funding a mortgage or a small business line and starts funding the federal government. Multiply by trillions and the banks’ model produces higher loan rates, reduced credit availability, and concentrated stress on community banks whose entire funding base is retail deposits. The ABA’s framing is not that banks would earn less, though they would; it is that the economy would lend less.
The White House Council of Economic Advisers looked at the same question and produced a number three orders of magnitude smaller. Its assessment put plausible deposit displacement in the low billions, around $2.1 billion in the scenario most cited, arguing that stablecoin demand comes overwhelmingly from crypto trading, cross-border flows, and dollar demand abroad, none of which is money sitting in a Kansas checking account today. In the CEA’s telling, the banks are counting every deposit that could theoretically move as a deposit that would move, ignoring deposit insurance, banking relationships, and the fact that money market funds have offered better rates than checking accounts for fifty years without ending bank lending.
The three-orders-of-magnitude gap is not really an empirical dispute. The two studies answer different questions. The ABA models the ceiling of a mature, frictionless, fully legal yield-bearing stablecoin market; the CEA models the floor of the current one. The honest answer, that displacement would start small and compound as the products improved, satisfies neither side, because the banks need the threat to be immediate and crypto needs it to be imaginary.
Davos, and the fight goes personal
The clearest public glimpse of how raw the conflict has become came at Davos in January, in an exchange between the two most powerful executives on either side.
JPMorgan chief executive Jamie Dimon, discussing stablecoin yield with Coinbase chief executive Brian Armstrong on a panel, dismissed Armstrong’s framing of deposit competition with a phrase that escaped the room within minutes: he told him he was full of s—, a vulgarity from the most measured banker of his generation that did more to reveal the temperature of the fight than any comment letter.
Armstrong’s argument, the one that drew the response, is the consumer-surplus case. American savers hold trillions in accounts paying a fraction of a percent while banks earn multiples of that on the float. Stablecoin yield, in his telling, is simply technology forcing banks to pay depositors something closer to the market rate for their money, and the deposit-flight studies are incumbents pricing their own margin as a systemic necessity. Coinbase has the most direct commercial stake of anyone in the room: its revenue share on USDC reserves is one of its largest income lines, and a world of legal yield pass-through is a world where its stablecoin business attacks bank deposits head-on.
Dimon’s counter is that payments and banking are different businesses with different risk, and that crypto wants banking economics without banking obligations: no lending mandate, no Community Reinvestment Act, no branch network, no discount window responsibilities, just the float. JPMorgan has hedged its own position, running deposit tokens and blockchain settlement internally while its chief executive argues against the retail version, a posture crypto reads as monopoly defense and banks read as prudence.
Then the President entered. In a late June post, Trump accused the banks of threatening and undermining the GENIUS Act, his own signed legislation, by lobbying to extend the yield ban and hobble stablecoin competition. A Republican president publicly siding against the banking lobby on a financial regulation fight is a genuinely new configuration in Washington, and it reshuffled assumptions on both sides about who holds the political high ground.
How the yield clause took CLARITY hostage
The CLARITY Act is a market structure bill. It assigns jurisdiction between the SEC and CFTC, defines when a digital asset is a security or a commodity, and creates the registration framework the industry has demanded for a decade. It is not, on its face, a stablecoin bill; the complete stablecoin framework already passed in GENIUS. But Washington does not respect bill boundaries, and the yield war has annexed it.
The banking lobby’s ask is straightforward: use CLARITY to close the loopholes GENIUS left open. That means extending the interest prohibition from issuers to exchanges and affiliates, killing the rewards programs that pay stablecoin holders today, and blocking any structure that passes reserve income to users. Bank trade groups have made support conditional on those provisions, and enough senators from both parties bank with them, figuratively and literally, to make the demand real.
Crypto’s response arrived the last week of June, when Coinbase announced it could no longer support CLARITY in its current trajectory, precisely because the yield restrictions being negotiated into it would, in the company’s view, entrench the ban permanently. The industry’s most important lobbying force turning against the industry’s most important bill was the loudest possible signal that the yield clause now outweighs the rest of the legislation for the companies whose business models depend on it.
Chairman Scott’s postponement of the markup followed within days. The delay was procedural on its face and structural in substance: there is no current text that both the banks and the crypto industry will accept, and members have little appetite to vote on a bill that one of the two richest lobbies in the country has promised to remember.
The market structure everyone claims to want is now collateral in a fight over a clause most voters have never heard of.
The political calendar sharpens everything. The window before the midterm campaign consumes Congress is measured in weeks, and both lobbies know that a bill that slips past the summer likely slips past the election, into a Congress nobody can predict.
The Regulation Q rhyme
The yield war has a nearly perfect historical precedent, and both sides quote it selectively.
From 1933 until its final repeal in 2011, Regulation Q capped or prohibited the interest American banks could pay on various deposits, a Depression-era rule justified in language strikingly close to today’s: unrestrained competition for deposits would push banks into risky lending and destabilize the system. For four decades the cap was mostly invisible, because market rates sat near the ceiling. Then came the inflation of the 1970s. Market rates ran far above what banks were legally allowed to pay, and savers found themselves holding accounts that lost purchasing power by regulatory design.
The market’s answer was the money market mutual fund, an instrument that did precisely what yield-bearing stablecoins propose to do now: pool customer cash, buy short-term government paper, and pass the interest through. Money funds grew from nothing in 1971 to hundreds of billions by the early 1980s, deposit flight became a named phenomenon, disintermediation, and the banking industry warned in congressional testimony that the funds would destroy community banking and starve the economy of credit. Congress ultimately responded not by banning money funds but by deregulating deposits, phasing out the caps and letting banks compete for money at market rates.
Both sides of the 2026 fight live inside this story. Crypto cites it as proof that yield restrictions always fall, that savers eventually get paid, and that the catastrophic credit predictions never arrived; the banking system that emerged from deregulation was different, and more expensive to fund, but intact. The banks cite the sequel: the savings and loan industry, built entirely on cheap capped deposits, could not survive paying market rates for money, and its collapse consumed a decade and roughly $124 billion of public funds. Deposit competition did not end banking, but it did end the banks whose models required the subsidy.
The rhyme suggests the real question is not whether stablecoin yield eventually becomes legal in some form; the historical base rate says restrictions on paying savers erode. The question is which institutions are the savings and loans of this cycle, funded so completely by the interest-free float that they cannot survive its repricing, and whether they are banks, or the stablecoin issuers whose entire margin is the yield they currently keep.
The banks’ quiet hedge
While the trade associations fight the public war, the banks themselves are behaving like institutions that expect to lose it.
Barclays made the most explicit move, taking a stake in Ubyx, the stablecoin clearing network built to let banks and fintechs redeem stablecoins at par across issuers, the plumbing a bank needs on the day it decides to issue or distribute digital dollars itself. It was the first direct stablecoin infrastructure investment by a major bank since the yield fight broke into the open, and it was not framed as an experiment. Bank executives have begun saying the quiet part in public: if Congress makes yield-bearing digital dollars legal, the banks will go into that business, at scale, the day the ink dries.
The logic is the same one that has played out in every disruption cycle in finance. Banks did not want money market funds in 1975 or online brokerages in 1995, and once each became inevitable, banks became the largest providers of both. A legal yield-bearing stablecoin issued by a money center bank, with deposit-adjacent branding, existing customer relationships, and a balance sheet behind it, is a formidable product, and arguably a more dangerous one to Tether and Circle than to the banks themselves. Consortium efforts like Open USD, whose members built a shared issuance model precisely so no single firm owns the float, exist in part because everyone can see the banks coming.
The infrastructure is converging from the other direction too. Payment-first blockchains designed for regulated issuers, the category examined in the rise of dedicated stablechains, are being built with bank compliance requirements as first-order design constraints, not afterthoughts. The technical gap between a bank deposit and a stablecoin narrows every quarter; the yield clause is the last load-bearing wall between the two products.
That is the tell in this fight. Institutions do not invest in the rails of a product category they expect to strangle. The banks are lobbying to delay the future and provisioning to own it.
What each side gets wrong
The banks’ deposit-flight case has a real weakness at its center: it treats the current deposit franchise as an entitlement. The spread between what banks earn on customer money and what they pay for it is not a law of nature; it is a price maintained by friction, and every prior technology that reduced the friction, from money funds to high-yield online savings, transferred some of that spread to savers without collapsing credit. The system adapted, banks paid more for funding, lending got marginally more expensive, and the economy survived. Framing the next step in that fifty-year process as a $6.6 trillion cliff requires assuming, without much evidence, that this time adaptation is impossible.
Crypto’s consumer-surplus case has a mirror-image weakness: it waves away the run problem. Bank deposits are sticky in a crisis partly because they are insured and partly because moving them is slow. A yield-bearing stablecoin is uninsured and moves at the speed of a tap. In a March 2023-style panic, the same properties that make stablecoins efficient make them the fastest exit door in the system, and a world where a meaningful share of transactional money can flee to tokenized T-bills in an afternoon is a world with a new, untested amplifier under every banking stress. The honest crypto answer is that this risk is manageable with reserve rules and redemption gates; the marketing answer, that it does not exist, is the one that gets said out loud.
There is also a shared blind spot. Both sides model the fight as domestic, and the stablecoin market is not. The majority of dollar stablecoin demand originates outside the United States, from savers and businesses in weak-currency economies for whom the yield question is secondary to the dollar itself. Whatever Congress decides about interest, the offshore float will keep growing, and the deposits it drains first are not in Kansas; they are in Buenos Aires and Lagos and Istanbul. The American fight over yield is, in part, a fight over who gets to monetize a global phenomenon neither side created.
The endgame scenarios
Three broad resolutions are visible from here, and each has a coalition behind it.
The first is the status quo hardened: CLARITY passes with the extended yield ban, rewards programs die, and issuers keep the float. This is the banks’ victory condition. Its weakness is that it is probably temporary, an attempt to legislate against a spread that technology keeps making easier to deliver, enforced against an industry with a sitting president publicly on its side. Prohibitions that fight both technology and the White House have a poor record.
The second is the pass-through world: yield becomes legal, the banks execute their hedge, and within a few years the largest stablecoin issuers in America are the same institutions that spent 2026 warning about them. Deposits reprice, weaker banks consolidate, and the credit system adjusts to more expensive funding, the way it adjusted to money market funds. This is where the investment behavior of the banks themselves suggests the smart money already sits.
The third is stalemate: CLARITY dies this Congress, GENIUS remains the only law, and the yield question migrates to regulators and courts, fought product by product through rewards programs, tokenized money funds, and offshore issuers that Congress never manages to reach. This is the default outcome if the next few weeks produce no text, and default outcomes in a midterm year are heavy favorites.
The watch list for the next few weeks is short and concrete. First, whether Scott reschedules the markup before the August recess, because a markup date means a text exists that leadership believes can survive both lobbies, and no date means the third scenario is winning. Second, the behavior of the pro-crypto Senate bloc, which has to decide whether a CLARITY with a hardened yield ban is worth passing over the industry’s objection, or whether half the coalition walks. Third, the regulatory perimeter fights already underway: how the Treasury implements the GENIUS provisions on affiliates, whether the rewards programs survive their first supervisory challenges, and how aggressively tokenized money market funds, which pay yield legally because they are securities, get marketed as the stablecoin alternative the ban cannot touch. Every one of those is a proxy battle in the same war, and each can move independent of Congress.
It is also worth naming the quiet incentive nobody in the fight advertises: the federal government is a beneficiary of the stablecoin boom regardless of who keeps the yield, because every reserve dollar is demand for Treasury bills at the exact moment deficits need buyers. A Washington that quietly likes the float’s growth has reasons to resolve the fight in whatever way grows it fastest, and that logic, unspoken, may ultimately weigh more than either lobby’s studies.
The $6 trillion number that anchors the fight will keep being quoted whichever path unfolds, and it is worth remembering what it actually is: not a measurement, but a boundary claim, the banks’ estimate of everything they could lose in the world their opponents want. The real number will be discovered the way these numbers always are, one repriced deposit at a time. The only certainty is the direction. Money has spent fifty years migrating toward whoever pays for it, and no clause has ever held that line forever.
