Circle Suffers Worst Day Ever as CLARITY Act Draft Bans Passive Stablecoin Yield

Circle Internet Group (NYSE: CRCL) recorded its worst single-day trading session in company history on March 24, 2026, plunging 22% after draft legislative text from the CLARITY Act surfaced with sweeping restrictions on stablecoin yield products - a cornerstone of the revenue model shared by Circle and its primary distribution partner, Coinbase Global (NASDAQ: COIN) [1][2].

What the Draft Text Actually Says

The compromise language, first reported by journalist Eleanor Terrett citing an internal stakeholder email, was reviewed by crypto industry leaders in a closed-door Capitol Hill session on Monday and by banking representatives on Tuesday [3]. Sen. Thom Tillis is reviewing the final text before the bill advances to a Senate Banking Committee markup targeted for the second half of April [3].

The operative clause prohibits digital asset service providers - including exchanges, brokers, and affiliated entities - from offering yield "directly or indirectly" on stablecoin balances in any manner that is "economically equivalent" to bank interest [2][3]. The prohibition is written broadly by design, closing off workarounds through affiliates and structuring arrangements. The SEC, CFTC, and U.S. Treasury are jointly directed to define permissible reward structures and draft anti-evasion rules within twelve months of enactment [3].

The draft does carve out space for activity-based rewards tied to transactions, trading, lending, loyalty programs, promotions, subscriptions, and platform use - provided those rewards do not cross the economic equivalence threshold [2][3]. Industry observers flagged limits on tying rewards to balances or transaction amounts as a potential obstacle to designing workable incentive structures within the allowed framework [3].

Circle at the Center

USDC, the second-largest stablecoin by market capitalization with $75.30 billion in circulation at year-end 2025, derives its commercial appeal in part from the yield and rewards infrastructure that platforms like Coinbase offer holders [2]. Circle's reserve income from assets backing the USDC float constitutes the company's core revenue engine, and any legislative ceiling on yield-linked products threatens the demand dynamics that support that float [2].

Circle's previous worst single-day decline was -15.5% on June 27, 2025; Tuesday's 22% drop surpassed that mark by a wide margin [1]. The company is audited annually by Deloitte with monthly reserve attestations providing ongoing transparency, but compliance credentials offer little protection against a legislative rewrite of the yield product category itself.

"The agreement allows us to protect innovation while giving us the opportunity to prevent widespread deposit flight."

• Sen. Angela Alsobrooks

Sen. Alsobrooks, who co-authored the compromise alongside Sen. Tillis, framed the yield restriction as a necessary safeguard against bank disintermediation [2][3]. Financial institutions had argued throughout negotiations that interest-bearing stablecoin products could incentivize depositors to move cash off bank balance sheets, creating systemic risk to traditional lending capacity [1].

Coinbase Caught in the Crossfire

Coinbase shares fell 9% to 11% on the session, reflecting two distinct exposures. First, the company generated $364 million in stablecoin-related revenue in the fourth quarter of 2025 alone, a figure that analysts regard as directly at risk if the passive yield prohibition is enacted [2]. Second, Coinbase holds a $395 million strategic investment in Circle, meaning any sustained decline in CRCL valuation flows directly through the balance sheet [2].

Citi analyst Ronit Ghose maintained a $400 price target on Coinbase following the selloff, signaling conviction that the legislative outcome may be less severe than Tuesday's market reaction implied [2]. The broader analyst consensus had carried a $252 target for COIN, according to 247WallSt [2].

Coinbase CEO Brian Armstrong had previously pulled support for an earlier version of the stablecoin legislation in January specifically over yield restriction language [3]. His office had not issued a formal response to the new draft text as of market close on March 24.

Where the Bill Stands

The CLARITY Act's Senate Banking Committee markup represents the first of five sequential legislative steps before the bill can reach the President's desk [3]. With the markup targeted for the second half of April, market participants face weeks of uncertainty over whether the yield prohibition language will tighten, soften, or hold in its current form following bank representatives' Tuesday review [3].

The draft's directive to regulators to define permissible rewards within twelve months of enactment introduces a second layer of uncertainty: even if the bill passes with the current carve-outs intact, the practical scope of activity-based reward programs will not be fully defined until well into 2027 [3].

The House Financial Services Committee held a separate tokenization hearing on March 25, underscoring the legislative momentum around digital asset regulation across both chambers [3]. For Circle and Coinbase, the coming weeks of markup negotiations and bank-side lobbying will determine how much of the yield product architecture they have built around USDC survives into the next regulatory era [1][2][3].
