"You might not love every part of the Clarity Act, but I can guarantee you'll hate a future Dem version even more." — Patrick Witt, Executive Director, White House Crypto Council
Circle Internet Group (CRCL) lost $5.6 billion in market capitalization on March 24, 2026 — its worst single-session decline on record — after a leaked draft of the CLARITY Act revealed language banning passive yield on stablecoin balances. The stock fell approximately 20% intraday. Coinbase (COIN) dropped roughly 10% in sympathy. As of March 28, CRCL trades near $93, down from pre-leak levels above $118.
The provision at the center of the sell-off prohibits digital asset service providers from offering "yield directly or indirectly on stablecoin balances, or in any manner that is economically or functionally equivalent to bank interest." The language, drafted by Senators Thom Tillis (R-NC) and Angela Alsobrooks (D-MD) with White House backing, preserves activity-based rewards tied to payments and transactions but eliminates the passive income model that underpins Circle's business. Circle derives approximately 96% of its $2.7 billion 2025 revenue from interest on the Treasury bills backing USDC reserves. Coinbase earned $1.35 billion in stablecoin revenue in 2025, representing 19% of total revenue, through its USDC revenue-sharing arrangement with Circle.
The CLARITY Act passed the House 294-134 in July 2025 and has stalled in the Senate over this yield question since January 2026. Senator Cynthia Lummis stated in late March that negotiations are "99% of the way to resolution," though new political complications involving community bank deregulation provisions have emerged.
The CLARITY Act — formally the Digital Asset Market Clarity Act of 2025 (H.R.3633) — is the primary U.S. crypto market structure bill. It passed the House with bipartisan support (78 Democrats voted in favor) and was intended to establish clear jurisdictional boundaries between the SEC and CFTC over digital assets. The bill divides crypto assets into three regulatory categories: digital commodities, investment contract assets, and permitted payment stablecoins.
The stablecoin yield provision, added during Senate negotiations, states that digital asset service providers — exchanges, brokers, and affiliated entities — are barred from offering "yield directly or indirectly on stablecoin balances, or in any manner that is economically or functionally equivalent to bank interest."
Activity-based rewards remain permitted. Loyalty programs, promotional offers, subscription benefits, transaction-based rewards, and payment-linked incentives are explicitly allowed, provided they do not meet the economic equivalence standard. The SEC, CFTC, and U.S. Treasury are jointly directed to define permissible rewards and draft anti-evasion rules within 12 months of enactment.
The draft was reviewed by crypto industry leaders in a closed-door Capitol Hill session on Monday, March 24, with banks scheduled to review the same text the following day. According to reporting by FinTech Weekly, the provision was first surfaced by journalist Eleanor Terrett.
Circle Internet Group (CRCL): Circle reported full-year 2025 revenue of $2.7 billion, up 64% year-over-year. Reserve interest income accounts for approximately 96% of total revenue. The company manages $77.7 billion in USDC circulation as of late March 2026, with roughly 87% of reserves held in the Circle Reserve Fund — a Rule 2a-7 government money market fund managed by BlackRock and custodied by BNY Mellon.
The March 24 sell-off followed a 170% rally from Circle's February low near $50. The stock dropped to approximately $103 intraday before partially recovering. By March 28, CRCL had declined further to $92.70. Analyst consensus still holds a 12-month target of $127.56, with 11 of 12 analysts maintaining buy ratings, according to MarketBeat data.
Coinbase Global (COIN): Coinbase earned $1.35 billion in stablecoin revenue in 2025 (up from $911 million in 2024), with $364 million in Q4 alone. Under the USDC revenue-sharing agreement, Coinbase receives 100% of interest income from USDC held on its platform and splits 50/50 with Circle for USDC held elsewhere. Coinbase's share of total reserve income reached 54% of the $900 million pool in Q1 2025. The stock declined approximately 10% following the draft leak.
The economic relationship between Circle and Coinbase is central to understanding the market reaction. Circle issues USDC and manages its reserves. Coinbase distributes USDC and drives adoption. As of Q3 2025, USDC balances on Coinbase stood at $41.9 billion — up 39% quarter-over-quarter — representing more than half of all USDC in circulation.
Coinbase CEO Brian Armstrong's argument, documented in January 2026 posts, is that Coinbase's USDC rewards program is revenue sharing from interest earned on Treasury bills in USDC's reserve — structurally different from a savings account paying interest. The CLARITY Act's "economic equivalence" standard directly challenges this framing. If regulators determine that distributing reserve income to holders is functionally equivalent to paying interest, the entire revenue-sharing model must be restructured.
Armstrong's January intervention — posting publicly on X the night before a scheduled Senate Banking Committee markup — caused the hearing to be postponed. In February, he described White House conversations as "constructive" but stopped short of formal re-endorsement. As of late March, Armstrong has not commented publicly on the latest compromise text.
The CLARITY Act's path through Congress:
The Senate Banking Committee markup is targeted for the second half of April. Five sequential legislative steps remain before the bill can reach the president's desk. Senator Bernie Moreno warned that without advancement by May 2026, digital asset legislation may not receive serious consideration for years due to midterm election dynamics.
A new complication has emerged: Senate Banking Republicans are reportedly discussing attaching community bank deregulatory provisions to the CLARITY Act in exchange for House acceptance of the Senate's housing package. According to FinTech Weekly reporting, White House Crypto Council Executive Director Patrick Witt attended the March 19 meeting and appeared frustrated by the scope expansion.
The stablecoin yield ban has split the crypto industry along commercial lines.
Camp 1 — Accept and Move Forward: Companies with diversified revenue streams or those aligned with banking interests support passing the bill as written. The argument: regulatory clarity on market structure and SEC/CFTC jurisdiction matters more than the yield provision. A comprehensive framework reduces enforcement risk industry-wide.
Camp 2 — Reject Without Yield Protections: Coinbase and entities dependent on stablecoin distribution revenue oppose the current text. Their position: the yield ban hands banks a structural advantage by treating functionally identical products differently based on charter status. A bank-issued stablecoin paying interest through a deposit structure would face no equivalent restriction.
The divide maps directly to economic exposure. Firms earning material revenue from stablecoin distribution have financial incentive to resist. Firms earning primarily from trading, custody, or other services can afford to concede the yield point.
While the CLARITY Act moves through Congress, federal banking regulators are independently implementing the GENIUS Act (signed July 18, 2025), which governs stablecoin issuance by regulated financial institutions.
The Office of the Comptroller of the Currency published a Notice of Proposed Rulemaking on March 2, 2026, establishing a supervisory framework for payment stablecoin issuers covering licensing, reserves, redemptions, capital requirements, and operational standards. Key provisions include:
The FDIC is running a parallel rulemaking for FDIC-supervised institutions, with a comment period extended to May 18, 2026. The GENIUS Act takes effect on the earlier of January 18, 2027, or 120 days after regulators issue final rules.
The convergence of the GENIUS Act's OCC interest-prohibition framework with the CLARITY Act's yield ban language creates a regulatory environment where passive stablecoin yield faces restrictions from multiple directions.
The stablecoin market has reached $230+ billion in total circulation, with Tether (USDT) at $144 billion and USDC at $77.7 billion. Together they account for nearly 90% of stablecoin trading volume. USDC captured 64% of total transaction volume in early 2026, surpassing USDT by that measure for the first time.
Circle's business model concentration — 96% of revenue from reserve interest — creates a binary regulatory risk. If the yield ban passes as written and regulators interpret reserve income distribution as economically equivalent to interest, Circle must either: (a) retain all reserve income rather than sharing it, reducing USDC's competitiveness against offshore alternatives; (b) restructure distribution into activity-based reward frameworks that comply with the permitted categories; or (c) pursue a banking charter to operate under deposit-interest rules.
For the broader market, the CLARITY Act's passage would establish the first comprehensive U.S. regulatory framework for digital assets, granting the CFTC explicit spot-market authority over digital commodities and ending the SEC's enforcement-by-litigation approach. The economic cost of the yield ban must be weighed against the structural benefit of regulatory clarity across the entire digital asset sector.
The CLARITY Act stablecoin yield dispute has crystallized into a structural question about who is permitted to pay interest on dollar-denominated digital instruments. The current draft answer: banks can, crypto firms cannot. This asymmetry drives Coinbase's opposition and explains Circle's market reaction.
The economic stakes are quantifiable. Circle's $2.7 billion revenue base and Coinbase's $1.35 billion stablecoin income line face direct regulatory risk. The combined $78 billion USDC ecosystem — the largest regulated stablecoin by transaction volume — must adapt to whichever framework emerges.
Senator Lummis's assessment that negotiations are "99% resolved" on the yield question may prove accurate on the technical merits. The remaining 1% is political, and as the community bank deregulation complication demonstrates, political variables in Washington do not observe technical percentages. The midterm clock is running.
