CLARITY Act Senate Stall Tests $317B Stablecoin Yield Battle

On April 23, more than 120 crypto companies sent a joint letter to the Senate Banking Committee demanding an immediate markup on the Digital Asset Market Clarity Act. The letter, organized by the Crypto Council for Innovation and the Blockchain Association, represented the most coordinated lobbying push the industry has mounted since the bill cleared the House in July 2025 on a 294-to-134 bipartisan vote. The response from Senate Banking Committee Chairman Tim Scott was silence on scheduling.

Two days later, Senator Thom Tillis of North Carolina told reporters he needed additional time with bank lobbyists before endorsing any markup date. The late-April committee session the industry had treated as a near-certainty passed without action. What remains is a rapidly narrowing legislative corridor, a stablecoin market worth $317 billion, and a deepening divide between the banks that have lobbied hard for a yield prohibition and the crypto exchanges whose business models depend on distributing returns to users.

The stakes for both camps are not theoretical. Circle fell 20% in a single session in late March when a draft of the Senate bill leaked, wiping $5.6 billion in market capitalization. Coinbase disclosed that stablecoin-related revenue totaled $1.35 billion in 2025, representing nearly 20% of the company's total net revenue. The fight over what those balances earn is, in the plainest terms, a fight over which part of the financial industry owns the next generation of dollar-denominated settlement infrastructure.

The Architecture of the CLARITY Act

The Digital Asset Market Clarity Act, formally H.R.3633, divides the digital asset universe into three legal categories: investment contracts, restricted digital assets, and digital commodities. The first category stays under the Securities and Exchange Commission. The third category, covering spot markets for assets including Bitcoin and Ether, shifts to the Commodity Futures Trading Commission, ending years of jurisdictional warfare between the two agencies that has paralyzed enforcement and deterred institutional market participants.

The stablecoin provisions sit in a separate title. The bill defines a "payment stablecoin" as a digital asset pegged to a fiat currency, fully backed by liquid reserves, and redeemable one-to-one on demand. Only institutions licensed by the Office of the Comptroller of the Currency, federally insured banks, or state-chartered entities with equivalent oversight would be permitted to issue such tokens.

The most contested provision is the yield prohibition. The Senate draft negotiated primarily by Tillis and Democratic Senator Angela Alsobrooks of Maryland, after two months of closed-door sessions, would ban passive yield, defined as interest-like returns paid simply for holding a stablecoin balance. It would permit activity-based rewards tied to payments, transfers, or platform engagement. The distinction sounds surgical. In practice, it determines whether platforms like Coinbase can keep offering the USDC reward program that has become one of their most powerful tools for attracting and retaining user balances.

The Numbers That Explain the Lobby War

Stablecoin supply reached $317 billion in April 2026, equal to roughly 12% of total cryptocurrency market capitalization. USDC, issued by Circle, holds approximately $60 billion of that total. Tether's USDT commands roughly two-thirds of the broader market and is not issued by a U.S. entity, a distinction that will matter in what follows.

The financial stakes for individual companies crystallized in late March. A leaked version of the Senate draft triggered Circle's worst single session since its June 2025 IPO: shares fell 20.3% on March 24, removing $5.6 billion in market value. Coinbase fell roughly 10% in the same session before partially recovering. The selloff reflected a straightforward calculation by analysts: if passive yield rewards are banned, the most effective mechanism for attracting stablecoin balances onto U.S.-licensed platforms disappears.

Coinbase's 2025 full-year disclosure made the arithmetic concrete. Stablecoin revenue totaled $1.35 billion, representing 19.6% of $6.88 billion in net revenue. Fourth-quarter stablecoin revenue hit a record $364 million, driven by average USDC balances on Coinbase products reaching an all-time high of $17.8 billion. If the passive yield mechanism is removed, the revenue trajectory that equity analysts have been projecting into 2026 and 2027 requires significant revision.

Circle's exposure is different in kind. Its revenue model is built on earning interest from USDC reserves and distributing a portion to distribution partners. A yield ban would not directly cut Circle's spread income, but it would eliminate the most visible marketing tool for growing USDC supply: offering depositors a return they can see and compare. In markets where Tether pays nothing to holders and is not subject to U.S. licensing requirements, this asymmetry matters enormously.

Banks Are Winning One Fight and Losing Another

The banking industry's argument on stablecoin yield is coherent. A bank deposit account that pays interest must comply with deposit insurance rules, reserve requirements, and examination by a prudential regulator. A platform offering economically equivalent returns on a stablecoin balance while holding 100% of reserves in short-dated Treasuries operates without those obligations. The American Bankers Association and the Independent Community Bankers of America argued throughout the drafting process that permitting yield on stablecoins creates an unlevel playing field that accelerates deposit migration from regulated institutions.

The argument won in committee. The Tillis-Alsobrooks compromise text largely reflects the banks' preferred outcome: passive yield prohibited, activity rewards permitted. A Council of Economic Advisers analysis circulated in late March reportedly found limited evidence that stablecoin yields would materially drain bank deposits at current market size, but the political weight of the banking lobby has kept the prohibition in successive drafts.

The irony is that banks are fighting a different battle on the same bill simultaneously. A provision championed by Tillis would attach community bank deregulatory measures to the CLARITY Act, a legislative rider that banking groups support but that Senate Democrats and some Republicans view as unrelated to digital assets. That linkage has become one of four acknowledged obstacles standing between the current draft and a committee vote.

Coinbase, meanwhile, obtained a separate concrete win. The OCC approved the exchange's application for a national trust bank charter in April, giving it a federally supervised path to custody digital assets directly. The charter does not resolve the stablecoin yield question, but it inserts Coinbase into the regulated architecture the CLARITY Act is building and strengthens the company's negotiating position by demonstrating that it is willing to accept federal oversight on its own terms.

The GENIUS Act Is Running in Parallel

While the CLARITY Act stalls in committee, a related regulatory process is advancing on a separate track. On April 8, the Treasury Department, through FinCEN and the Office of Foreign Assets Control, published a joint notice of proposed rulemaking implementing the GENIUS Act, formally the Guiding and Establishing National Innovation for U.S. Stablecoins Act, which President Trump signed into law in July 2025.

The NPRM proposes the first federal anti-money laundering and sanctions compliance framework specifically for payment stablecoin issuers. Under the proposed rules, "permitted payment stablecoin issuers" would be treated as financial institutions under the Bank Secrecy Act. They would be required to maintain risk-based AML/CFT programs with designated compliance officers, independent testing, and customer due diligence standards. OFAC's portion of the rulemaking is more significant: it would create, for the first time, a binding regulatory obligation requiring a defined class of U.S. persons to maintain an effective sanctions compliance program. Comments close June 9.

The dual-track dynamic reshapes the competitive landscape in ways that extend beyond headline yield rules. Smaller stablecoin issuers that cannot absorb the cost of building AML programs alongside sanctions compliance infrastructure will face pressure to exit or delay launches, concentrating the market around Circle, Coinbase, and bank-affiliated issuers. Globally, the structure of the U.S. framework is being closely watched: the EU's Markets in Crypto-Assets regulation, Singapore's Payment Services Act, and Hong Kong's stablecoin licensing regime will all calibrate their own frameworks partly in reference to what Washington ultimately requires, and any yield restriction that applies only to U.S.-licensed issuers becomes a structural advantage for competitors operating under lighter-touch regimes.

May Is Not a Soft Deadline

The Senate operates on a calendar that is less forgiving than it appears from the outside. The Banking Committee must advance the CLARITY Act before the summer recess to give the full Senate time to schedule a floor vote ahead of the midterm election season, when vulnerable members become unwilling to cast difficult votes on complex financial legislation. Faryar Shirzad, Coinbase's chief policy officer, told Fox Business on April 16 that the company expected a committee markup as early as April and a Senate floor vote in May. Both milestones have now slipped.

The 120-firm letter of April 23 cited precisely this pressure, warning that "every week of delay reduces the probability of enactment in this Congress." The signatories included exchanges, wallet providers, infrastructure firms, and asset managers representing the bulk of U.S. retail and institutional crypto trading volume.

According to people familiar with the committee's internal discussions, cited by CoinDesk and FinTech Weekly across multiple reports, four obstacles must be cleared before a markup can proceed: the stablecoin yield text itself, which Tillis has not formally released to the public; DeFi provisions that several Senate Democrats oppose on illicit finance grounds; ethics language barring senior government officials from profiting from digital assets; and the community bank deregulation rider. Treasury Secretary Scott Bessent's Wall Street Journal op-ed advocating a compromise framework on stablecoin yield shifted the dynamic enough to bring Coinbase CEO Brian Armstrong back to supporting the bill after the company's January withdrawal, but Bessent's intervention has not resolved the three remaining obstacles.

If the Banking Committee does not hold a markup before mid-May, the floor vote timeline Coinbase projected becomes structurally implausible in this Congress. The bill would need to restart in the 120th Congress, resetting two years of industry lobbying, two parallel agency rulemaking processes under the GENIUS Act, and a House vote that drew more bipartisan support than almost any financial services legislation of the past decade.

The peculiar position of the CLARITY Act in late April 2026 is that its biggest advocates and its most significant obstacles are the same people. Tillis negotiated the yield compromise that has enough political support to survive a floor vote, but he is also the senator asking for more time with the banks the compromise was meant to satisfy. The 120 companies that signed the industry letter want speed; the senator most responsible for the bill's bipartisan credibility wants process. The legislative calendar does not care about the difference.

What the final text looks like when and if it clears committee will determine more than the economics of stablecoin rewards. The CLARITY Act hands the CFTC jurisdiction over the spot market for Bitcoin, Ether, and a broad class of other tokens, a structural shift that would end the legal ambiguity that has kept institutional capital at the margins of digital asset markets for the better part of a decade. The yield provision is the negotiating residue of a much larger design. Getting the design wrong in the name of resolving the residue would be a poor trade. Whether the Senate Banking Committee recognizes that before the window closes is the question that 120 firms, a $317 billion market, and two competing federal agencies are asking simultaneously, and so far the answer has been silence.
