The stablecoin yield ban didn't move the interest. It locked in who already keeps it.

On Tuesday, June 30, more than 140 companies announced a new digital dollar. The roster behind OUSD, short for Open USD, reads like a map of the payments economy: Visa, Mastercard, American Express, Stripe, BlackRock, Google, Shopify, Coinbase, plus banks from BNY to Standard Chartered. The coin will be run by an independent company called Open StandardOpen StandardThe independent company set up to govern and operate OUSD on behalf of the consortium, led by interim CEO Zach Abrams., and its economic design is the interesting part: partners collect nearly all of the interest earned on the reservesreservesThe pool of real assets, mostly short-term US government debt, that a stablecoin issuer holds so every token can be redeemed for $1. backing the token, after a small management fee.

Four days later, on July 4, the Senate began its summer recess without voting on the CLARITY ActCLARITY ActThe broader crypto market-structure bill (H.R. 3633), passed by the House in July 2025 and now stalled in the Senate; one of the fights holding it up is whether to extend the interest ban from issuers to exchanges and platforms., the broad crypto market-structure bill the House passed a year ago. The White House's crypto adviser had publicly targeted Independence Day for passage, 'a tremendous birthday present for America,' as he put it in May. Among the fights that kept the present unwrapped: whether anyone besides the issuerissuerThe company that creates a stablecoin and holds its reserves, Circle issues USDC, Tether issues USDT. may pay stablecoin holders interest.

Both events trace back to one sentence of law. The GENIUS ActGENIUS ActThe US stablecoin law signed July 18, 2025; among other rules, it bans issuers from paying any interest or rewards to people for holding their stablecoins., signed July 18, 2025, says a stablecoin issuer may not pay 'the holder of any payment stablecoin any form of interest or yieldyieldThe income an investment produces, expressed as a percentage per year, like the interest rate on a savings account. (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention of such payment stablecoin.' Note who is named: the issuer. Not the exchange where you keep the coin, not the app you spend it from. This article asks one narrow question: when the law fixes the holder's share of stablecoin interest at zero, where does the interest actually go, and did this week just show us the answer?

A stablecoin is a digital token engineered to always be worth one dollar. The issuer takes your dollar, gives you a token, and parks the dollar in reserves, overwhelmingly short-term US government debt, the Treasury bills that currently pay around 4% a year. The token in your wallet pays you nothing. The T-bills behind it pay the issuer constantly. That gap is the entire business.

The gap is not small. Circle's fourth-quarter 2025 results, published in February, show $733 million of reserve income in a single quarter, earned on average USDC circulation of $76.2 billion, a disclosed 'reserve return ratereserve return rateCircle's disclosed measure of the annualized interest its reserves earn as a share of average USDC in circulation, 3.8% in late 2025.' of 3.8% a year. In plain terms: every $100 of USDC in the world generates about $3.80 of interest annually, and the person actually holding the $100 has a legal claim, from the issuer, to exactly none of it. It is the business model of the old checking account: your balance pays zero while the institution invests it at market rates. Finance calls the invested balance 'floatfloatMoney sitting in customers' balances that a company gets to invest and earn interest on before it is spent or withdrawn..'

The GENIUS Act did not create this arrangement, checking accounts, gift cards and PayPal balances have always worked this way. What the Act did was outlaw the one competitive force that could unwind it. In a normal market, a new issuer could bid for customers by handing back the $3.80, the way high-yield savings accounts bid for deposits. Section 4(a)(11) makes that bid illegal. The float is not just profitable now; it is legally protected from yield competition at the issuer level.

No permitted payment stablecoin issuer... shall pay the holder of any payment stablecoin any form of interest or yield.

So where does the $3.80 go? For USDC, the answer is in Circle's own IPO paperwork. The S-1S-1The registration document a company files with the SEC before going public, which discloses its finances in detail. it filed with the SEC in April 2025 shows total revenue and reserve income of $1.68 billion for 2024, more than 99% of it interest on reserves, against 'distribution, transaction and other costs' of $1.01 billion. Sixty cents of every dollar the reserves earned was paid out to the companies that put USDC in front of users. Coinbase alone received $907.9 million.

The mechanics matter. Under the agreement described in the S-1, Coinbase keeps 100% of the reserve income earned on USDC sitting on its own platform, and splits the income on all remaining USDC roughly 50-50 with Circle. That gives Coinbase a straightforward incentive: pull coins onto its platform. It has worked, by the first quarter of 2026, Coinbase reported that more than a quarter of all USDC in circulation sat in its products, and that it captures about half of the total economics of the coin.

Here is the number that reframes the yield ban: in the fourth quarter of 2025, two quarters after GENIUS became law, Circle's distribution costs were $461 million against $770 million of total revenue and reserve income. That is 59.9%, statistically indistinguishable from 2024's 60.3%. The ban did not push the distributors' share up. It did not need to. It froze a split that already sent the majority of the interest up the chain, and removed the legal mechanism, issuers competing on yield, by which holders could ever have clawed it back.

If the interest flows to whoever controls distribution, the logical endgame is for the distributors to cut out the issuer and keep the whole stream. That is a fair one-sentence description of OUSD. The consortiumconsortiumA group of companies that jointly own and govern a shared venture instead of one firm controlling it.'s design, per the launch coverage, pays 'nearly all' of the reserve interest to partner companies after Open Standard's management fee; Fortune's softer phrasing is 'most.' Minting and redeeming will be free, the coin is slated to go live later in 2026, and the venture is led by interim CEO Zach Abrams, who co-founded the stablecoin platform Bridge that Stripe bought for $1.1 billion. Notably, Coinbase, Circle's principal distributor, is on the OUSD partner list too.

Read Circle's 16% one-day stock drop carefully. It is a market reaction, not an economic effect: what got repriced was not the interest on anyone's reserves but investors' estimate of Circle's power to keep its share of that interest when its distributors can issue a coin of their own. The $3.80 per $100 is unchanged. The fight over which balance sheet it lands on is what moved.

One caution before extrapolating OUSD to dominance: this has been tried. USDG, a Paxos-issued consortium coin launched in November 2024, shares roughly 97% of its economics with partners including Robinhood and Kraken, and after twenty months it holds about $3 billion in circulation, a rounding error next to Tether's $183 billion. OUSD's backers are categorically bigger. But USDG's stall despite generous yield-sharing is evidence that distributor economics alone do not conjure adoption.

There is one channel through which ordinary holders still receive something: platform 'rewards.' Because GENIUS names only issuers, Coinbase pays USDC holders on its platform a 3.5% annual reward, funded, in economic substance, by the distribution payments it receives from Circle. Even this leak has narrowed: since December 15, 2025, only subscribers to Coinbase OneCoinbase OneCoinbase's paid monthly subscription; since December 2025, only its members earn the exchange's USDC rewards., the exchange's paid membership, earn it; free users get nothing.

How much escapes? In the first quarter of 2026 Coinbase booked $305 million of stablecoin revenue, $1.22 billion annualized, against $19 billion of average USDC balances on its platform. If every one of those dollars earned the full 3.5%, the payout would be about $665 million a year. That is a deliberate overestimate, since most balances no longer qualify. Even so, the platform keeps at least 45 cents of every stablecoin dollar it collects; the true figure is higher.

And that remaining leak is precisely what the plumbing crews are working on, on three fronts at once:

• Regulators: on February 25, 2026 the OCC proposed a rule creating a 'rebuttable presumption' that any arrangement in which an issuer coordinates with an affiliate or 'related third party' to pay holders yield is banned interest, the issuer must prove to the OCC that the scheme is not evasion. The comment period closed May 1; the FDIC issued a parallel proposal in April. Neither is final.
• The bank lobby: the American Bankers Association and 52 state bankers associations have urged Congress to stop 'issuers and affiliated platforms' from offering yield, and the Bank Policy Institute argues platform rewards funded by issuer distribution payments are 'a mere pass-thru from the issuer to the token holder.' More than 3,200 bankers signed a Senate letter to the same effect.
• Congress: the compromise on the table in the CLARITY negotiations, from Senators Tillis and Alsobrooks, would ban intermediaries from paying deposit-like yield on passive stablecoin holdings while allowing rewards tied to activity. Banks object that activity-based rewards rebuild the loophole under another name.

Honesty requires a caveat about July 4: the yield question is one of the fights that stalled CLARITY, but reporting attributes the missed target at least as much to a standoff over ethics provisions aimed at the Trump family's crypto ventures. What matters for this article is the direction of every live proposal: not one of them would move interest toward holders. Each would formalize that it stays upstream.

The United States has banned interest before. The Banking Act of June 16, 1933 outlawed interest on checking deposits, and the Federal Reserve's Regulation QRegulation QThe Depression-era US rule that banned interest on checking accounts and capped rates on savings accounts; the caps ended in 1986 and the checking-account ban in 2011., issued that August, capped what banks could pay on savings. For four decades the caps mostly sat below market rates without much drama. Then inflation arrived. By 1979-1981, Treasury bills yielded double digits, the 1981 average was about 14%, while Regulation Q held passbook savings near 5%.

Savers found the wrapper the ban did not cover: money market mutual funds, which pool cash into T-bills and pass the interest through. Federal Reserve flow-of-funds data show fund assets going from $3.9 billion at the end of 1977 to $186.3 billion at the end of 1981, a roughly 45-fold rise in four years, and $220 billion by end-1982.

Congress capitulated in two steps. The 1980 DIDMCADIDMCAThe Depository Institutions Deregulation and Monetary Control Act of 1980, which ordered a six-year phase-out of the caps on savings-account interest rates. ordered the savings caps phased out within six years. Then the Garn-St Germain ActGarn-St Germain ActThe 1982 law, signed October 15, in which Congress let banks offer market-rate money market deposit accounts, legalizing the yield savers had already fled to., signed October 15, 1982, authorized money market deposit accounts, bank accounts with no rate ceiling, which went live that December. The money promptly started coming home: 1983 was the first year money fund assets fell. The last piece, the 1933 checking-account ban itself, survived until Dodd-FrankDodd-FrankThe 2010 financial-reform law; among many changes, it repealed the 1933 ban on paying interest on checking accounts, effective July 2011. repealed it effective July 2011. The full arc took 78 years, but the direction was set the moment savers had somewhere to go: yield suppressed by law eventually escaped, and the law was rewritten to follow it.

The 1970s analogy is seductive: another interest ban, another wrapper, tokenized Treasury funds, which put money-fund shares on a blockchain and pass yield through legally, waiting to absorb the flight. The Treasury Borrowing Advisory Committee has already gamed out the stakes, estimating in April 2025 that about $120 billion of T-bills sat behind stablecoins and projecting a possible $2 trillion market by 2028.

But the escape is not happening, and one number explains why the analogy breaks: Tether. USDTUSDTThe largest stablecoin, issued by Tether, with about $183 billion in circulation, roughly 58% of the market. pays holders nothing, discloses no revenue-sharing with anyone, kept $1.04 billion of profit in the first quarter of 2026 alone, and holds about $183 billion in circulation, roughly 58% of the $320 billion market. In 1980, deposits fled to whoever paid yield. In 2026, the largest pool of stablecoin money demonstrably does not care. People hold USDT for dollar access and utility, not return. Meanwhile the yield-passing wrapper remains tiny: all tokenized Treasury funds together hold about $14.8 billion, BlackRock's BUIDL, the largest, about $2.2 billion, against $320 billion of stablecoins.

That difference flips the political economy. Regulation Q died because savers voted with their feet and Congress legalized where they had already gone, Garn-St Germain ratified a fait accompli. Today the feet are not moving, the incumbents profiting from the float include the largest banks and card networks via OUSD, and every pending rule tightens rather than loosens the ban. The pressure runs toward closing the Coinbase-shaped leak, not toward a Garn-St Germain for stablecoin holders.

So the answer to the narrow question is visible in one week of news. The interest on stablecoin reserves, roughly $3.80 a year per $100, some $12 billion annually across a $320 billion market at current rates, never went away and never will while T-bills pay. Congress fixed the holder's share from the issuer at zero; Circle's filings show about 60 cents of each interest dollar already flowing to distributors before and after the ban, unchanged; OUSD is 140 companies organizing to collect nearly all of it; and the CLARITY fight is over whether the last few cents that reach holders through platform rewards should be shut off too. The ban did not eliminate the float. It decided, by omission and now perhaps by design, who keeps it.
