Stablecoin Yield: The Fight That Stalled US Crypto Law

The CLARITY Act is the most advanced crypto market structure bill in US history. It cleared the House by 294–134 in July 2025 and the Senate Banking Committee by 15–9 in May 2026. It has been sitting on the Senate calendar since June, waiting for a floor vote that finally has a date: 15 September 2026.

Most of the bill is not controversial. The SEC–CFTC jurisdictional split, the registration regime for digital commodity exchanges, the custody and disclosure requirements — these were largely settled months ago.

What has held everything up is a fight over a single mechanism: whether a crypto platform can pay you a return for parking dollars on it. It sounds like a technical footnote. It is actually the most consequential distributional question in US financial policy right now, and it has already cost the bill votes on both sides of the aisle.

The number that started the war

Start with the gap that makes this worth fighting over.

A standard Chase savings account has paid an annual percentage yield of 0.01%. By the end of 2025, Coinbase was offering roughly 4% and Kraken roughly 5% in rewards on USDC balances held on their platforms.

Same dollar. Same overnight risk profile in the user’s mind. Four hundred times the return.

That is not a crypto trading product competing with crypto trading products. It is a cash product competing directly with the deposit base that funds bank lending. Stablecoins compete with bank deposits, brokerage sweep accounts and Treasury funds for the same marginal dollar, which is why the banking industry treated this as an existential issue rather than a regulatory nuisance.

The loophole: who is actually banned from paying you

The GENIUS Act, signed into law in July 2025, established the first federal framework for payment stablecoin issuers — reserve requirements, redemption obligations, anti-money laundering provisions. Section 4(a)(11) of that Act prohibits a payment stablecoin issuer from paying holders any form of interest or yield solely in connection with holding, using or retaining the stablecoin.

The drafters wrote the prohibition narrowly. It binds issuers. It says nothing about exchanges, platforms or affiliates.

That distinction is the entire fight. Circle, as the issuer of USDC, cannot pay you. Coinbase, as a platform holding USDC on your behalf, can. And because Circle earns interest on the Treasury reserves backing USDC, it can share that reserve income with Coinbase, which then pays a rewards rate to users who keep balances on the platform.

The mechanics are not hidden. Circle’s S-1 filing acknowledged that the greater the share of circulating USDC held on Coinbase’s platform, the greater the share of reserve income payable to Coinbase. The incentive is explicit and it works: Coinbase disclosed average USDC balances inside its products of around $19 billion in Q1 2026, more than a quarter of all USDC in circulation, and reported $305 million in stablecoin revenue for the quarter — the single largest line inside a subscription and services business contributing 44% of total revenue.

A similar structure exists elsewhere. In the Paxos–PayPal arrangement, Paxos is the technical issuer while PayPal has paid rewards of roughly 4% to PYUSD holders.

Banks call this a loophole. The crypto industry calls it a deliberate feature of a law Congress wrote with its eyes open. Both readings are defensible, which is exactly why it could not be resolved by argument.

What each side is actually claiming

The lobbying has been unusually coordinated. On 8 May 2026, six major banking trade groups — the American Bankers Association, the Bank Policy Institute, the Consumer Bankers Association, the Financial Services Forum, the Independent Community Bankers of America and the National Bankers Association — sent a joint letter to the Senate Banking Committee targeting the bill’s stablecoin rewards provision.

On the other side, Coinbase CEO Brian Armstrong said in January 2026 that the exchange could not support the Senate draft as written, given language prohibiting platforms from offering yield on stablecoins. JPMorgan’s Jamie Dimon has publicly warned that the framework could ultimately fail, arguing it would let stablecoin issuers effectively pay deposit interest without bank-style protections.

The compromise that almost worked

After roughly four months of negotiation facilitated by the White House, Senators Thom Tillis (R-N.C.) and Angela Alsobrooks (D-Md.) produced a deal in May 2026. Its logic is simple and, on paper, elegant:

• Prohibited: rewards paid in a manner that is economically or functionally equivalent to interest or yield on an interest-bearing bank deposit. In practice, no paying people to do nothing but hold a balance.

• Permitted: rewards tied to bona fide platform activity and genuine stablecoin transactions — incentives for using the coin as a payment instrument rather than as a savings vehicle.

• Deferred: regulators and the Treasury Secretary would be tasked with building a disclosure framework and a catalogue of permissible reward categories after passage.

The distinction is between yield on idleness and rewards for activity. It gives banks the deposit protection they wanted and gives crypto platforms a route to keep incentive programmes alive. The compromise was folded into the 309-page committee text released on 12 May, and the Senate Banking Committee advanced the bill two days later, with Senators Alsobrooks and Ruben Gallego breaking with their Democratic colleagues to vote in favour.

For about a month, it looked settled.

Why it fell apart anyway

The banks decided the compromise was not tight enough

By late July, the Bank Policy Institute was arguing publicly that the updated CLARITY Act text still needed a stronger prohibition on interest-like payments, on the view that the language as drafted would leave routes to pay yield for holding stablecoins beyond the permitted activity-based allowance. The banking coalition’s consistent position has been that the prohibition on interest-like rewards for holding should be tightened while genuine transaction-based rewards are preserved.

The unresolved problem is definitional. Nobody has drawn a durable line between a reward for activity and a reward for balances, because sufficiently loose activity requirements collapse the distinction entirely. A rewards rate gated behind a subscription tier or a minimum monthly transaction still pays out on balance size.

And then it started costing Republican votes

This is the development that changed the arithmetic. Community banks — locally owned, politically well-connected, present in every state — spent weeks lobbying Senate Republicans directly on the deposit and lending consequences of enshrining stablecoin rewards in statute.

It worked. Senators Josh Hawley and Jerry Moran signalled they would oppose the CLARITY Act unless the stablecoin rewards text is amended.

A bill that already needed seven to ten Democratic crossovers now has Republican defections on the same clause. That is the real reason September looks difficult.

Combine that with the separate Democratic objections on ethics, consumer protection and illicit finance, and the path to 60 votes on 15 September becomes genuinely hard to draw.

The parallel track nobody is watching closely enough

Here is the part most coverage misses. While Congress has been deadlocked, a banking regulator has been quietly resolving the same question by rulemaking.

On 25 February 2026, the OCC issued its first substantive notice of proposed rulemaking under the GENIUS Act. Alongside reserve, redemption and disclosure requirements, it proposed a rebuttable presumption on the yield question: if an issuer has an arrangement with an affiliate or related third party, and that party pays interest or yield to holders in connection with holding the stablecoin, the arrangement is presumed to violate the statutory prohibition.

That inverts the burden of proof. The parties must demonstrate the payment is not connected to holding, use or retention — a deliberately high bar. Legal analysts have read the proposal as capturing both the Circle–Coinbase revenue-sharing structure and the Paxos–PayPal model as they currently operate. The proposal does preserve carve-outs, including independent merchant discounts for paying in stablecoins and revenue sharing with white-label distribution partners.

The comment period closed on 1 May 2026. Banking trade groups requested an extension; the OCC declined.

The strategic implication is significant: if the CLARITY Act fails on 15 September, the yield loophole does not automatically survive. It may be closed by a federal banking regulator instead — on terms the crypto industry had no vote on, with a definition of yield that the rule never actually supplies, and with the ambiguity resolved case by case in supervision rather than in statute.

What this means commercially

The direction of travel is consistent across both tracks: the US is steering stablecoins towards being payment instruments rather than deposit substitutes. Whether that arrives by statute or by supervision, business models built on paying for idle balances are on the wrong side of it.

What to watch

1. Whether an amendment on rewards appears before the 15 September vote. A tightened Section 404 is the most plausible route to bringing Hawley and Moran back and reaching cloture.

2. Whether the yield question gets split off entirely. Deferring it to separate legislation would unblock the rest of the bill — and is the compromise nobody has publicly proposed yet.

3. The OCC final rule. If the rebuttable presumption survives largely intact, the loophole closes regardless of what Congress does.

4. Coinbase’s rewards disclosures. Any change to how the programme is structured or described will be the clearest signal of where the company thinks this lands.

5. Litigation. A statutory ambiguity this valuable, resolved by a rule rather than a statute, is an obvious candidate for a court challenge.

The bottom line

A 300-page bill that would reorganise the entire regulatory architecture of American crypto markets has been stalled for most of a year by an argument over roughly four percentage points on a cash balance.

That is not a drafting failure. It is an accurate reflection of what is at stake. Deposits are the raw material of bank lending, and a product that pays four hundred times what a savings account pays, without the associated regulatory overhead, is a genuine competitive threat rather than an imaginary one. The crypto industry’s counterargument — that the outflow projections are inflated and that the real concern is payment fee revenue — is also credible.

Both sides are defending something real, which is why no amount of drafting has settled it. On 15 September we find out whether the Senate can live with the compromise it has, or whether the answer to a question about four percent gets handed to a banking regulator instead.
