1. The Market Overreacted — at Least According to Wall Street
When a draft revision of the Digital Asset Market Clarity Act surfaced with language restricting passive stablecoin yield, the market's response was swift and severe. Circle's shares plunged approximately 20% on Tuesday, unwinding a significant portion of the stock's extraordinary 170% rally since early February. Coinbase fell close to 10% in sympathy, given its deep revenue-sharing relationship with Circle over USDC interest income. But two separate Wall Street research teams — one from Citigroup and one from Bernstein — have independently concluded that the market's reaction conflated the mechanics of who earns yield with who distributes it, and that the fundamental investment case for Circle's business model remains largely intact despite the regulatory development.
2. What the Draft Clarity Act Actually Says About Stablecoin Rewards
The latest revision of the Digital Asset Market Clarity Act, negotiated between Senators Angela Alsobrooks and Thom Tillis, proposes to ban yield payments made simply for holding stablecoins on a passive basis. The legislation draws a distinction between passive accumulation of yield — which it seeks to prohibit, in response to banking industry pressure — and activity-based rewards tied to transactions, trading, or payments, which it would permit under narrowly defined conditions. The distinction is motivated by the banking sector's concern that passive stablecoin yield structures function as a direct substitute for interest-bearing bank deposits, drawing deposits out of the traditional banking system and into uninsured crypto platforms. That concern has driven months of stalled legislative negotiations and is the primary reason the draft language is stricter than many in the crypto industry had hoped for.
3. Citigroup: A Scaling Setback, Not an Investment Thesis Killer
Citigroup analysts led by Peter Christiansen addressed the market reaction directly in a research note published on Tuesday, framing the regulatory development as a potential friction point rather than an existential threat. Their central argument is that Circle's revenue model is not directly exposed to the restrictions being proposed. Circle earns income by holding the assets that back USDC in reserve — primarily short-duration Treasury instruments — and that reserve income accrues to Circle regardless of whether downstream platforms are permitted to pass yield along to retail users. What the proposed restrictions would affect is not Circle's revenue generation but the incentive structures that platforms like Coinbase use to encourage customers to hold and use USDC on their services. Citi maintains a price target of $243 on Circle shares, which were trading near $100 at the time of publication, and assigns the stock a high-risk rating that reflects both the upside potential and the regulatory uncertainty embedded in the current environment.
4. The Volume vs. Circulation Distinction
A key analytical point in Citigroup's defence of Circle concerns how USDC adoption should be measured. The bank argues that stablecoin circulation — the total supply of USDC outstanding at any given time — is a secondary indicator, while transaction volume is the primary signal of genuine adoption and long-term utility. If passive yield restrictions reduce the incentive for retail users to hold USDC as a savings-like instrument, the supply of USDC in circulation may temporarily contract. But that contraction does not necessarily translate into a reduction in the number of transactions processed, the number of payment rails using USDC, or the trading and settlement activity for which the stablecoin is deployed in institutional and DeFi contexts. The bank summarised this position clearly: it maintains that volume is the key indicator of adoption and that circulation alone is an incomplete metric.
5. Bernstein: Investors Are Confusing Who Earns and Who Distributes
Bernstein analysts led by Gautam Chhugani published their own defence of Circle in a Wednesday report, focusing specifically on the market's apparent confusion about the structure of USDC's economic ecosystem. Their central contention is that investors are incorrectly treating Circle as if it were directly exposed to the yield restrictions, when in fact the proposed rules target the distribution layer — platforms like Coinbase that currently pass a portion of USDC reserve income to retail holders as rewards — rather than the issuer layer where Circle operates. Under the current structure, Circle earns reserve income from the assets backing USDC and transfers a share of that income to distribution partners, most notably Coinbase, which then uses it to fund the approximately 3.5% yield product it offers customers on USDC balances. The Clarity Act's restrictions, as currently drafted, would require Coinbase to restructure that product — but Circle's underlying income stream is not the target.
6. Circle's Financial Model Stands on Its Own
The numbers behind this argument provide useful context. Circle generated $2.64 billion in reserve income during fiscal year 2025, a figure that reflects the return on the Treasury and cash-equivalent assets held against the approximately $80 billion in USDC outstanding at the time. That income is structurally tied to the size of the USDC reserve base and the prevailing short-term interest rate environment — neither of which is directly affected by whether retail holders receive passive yield. Bernstein further notes that USDC's growth from approximately $30 billion to $80 billion in circulating supply over the preceding two years was driven primarily by trading activity, use as collateral in DeFi protocols, and adoption as a payments and settlement instrument — not by the yield product that platforms like Coinbase make available to retail customers. That growth trajectory speaks to demand for USDC as a functional infrastructure asset rather than a yield-seeking vehicle.
7. The Coinbase Complication
While the analyst consensus points toward Circle being less affected than the market initially assumed, the same cannot be said without qualification for Coinbase. Stablecoin revenue at Coinbase reached $1.35 billion in fiscal year 2025, making it the second-largest driver of the exchange's revenue behind transaction fees. The existing arrangement between Circle and Coinbase, under which Coinbase receives a portion of reserve income in exchange for promoting USDC to its user base, represents a meaningful commercial relationship that the proposed rules would force into restructuring if passive yield distributions to users are prohibited. Coinbase CEO Brian Armstrong has publicly stated that a yield ban would ironically make Coinbase more profitable in the short term, since the exchange currently pays out significant sums in rewards. However, he has argued against the restriction on competitive grounds, contending that limiting USDC yield disadvantages regulated U.S. stablecoins relative to offshore alternatives.
8. Tether's Audit Announcement Adds Competitive Pressure
The Circle selloff was further compounded by a separate development from Tether — Circle's primary global rival — which announced this week that it has engaged one of the Big Four accounting firms to conduct a full audit of its reserves. Tether's USDT remains the dominant stablecoin by market capitalisation globally, but has long been challenged on the credibility of its reserve disclosures relative to Circle's more transparent reporting standards. If the Tether audit proceeds successfully and produces a clean opinion from a recognised major firm, it would substantially strengthen USDT's credibility with institutional counterparties — reducing one of the competitive disadvantages that has historically allowed USDC to capture market share in environments where auditability and regulatory standing are valued. That dynamic adds a layer of near-term competitive uncertainty on top of the legislative risk.
9. Activity-Based Rewards as the Regulatory Escape Hatch
Multiple analysts and industry sources have noted that the Clarity Act's distinction between passive and activity-based rewards creates a potential pathway for platforms to preserve meaningful stablecoin incentive structures within the letter of the new rules. If the final legislation permits rewards tied to transactions, payments use, or other demonstrable platform activity, Coinbase and similar platforms may be able to restructure their USDC yield products into programmes that satisfy the regulatory requirement while continuing to provide competitive incentives for users to hold and transact in USDC. The legal and structural complexity of defining what constitutes "activity" versus "passive holding" will likely be a subject of extended regulatory guidance after the bill passes — and industry participants are already modelling how their products would need to evolve to remain compliant.
10. The Broader Stakes for U.S. Stablecoin Competitiveness
Underlying both the Citigroup and Bernstein analyses is a concern that extends beyond Circle's stock price: whether the stablecoin yield restrictions, in their current form, would disadvantage U.S.-regulated stablecoins in the global competitive landscape. With Citigroup estimating that the global stablecoin market could grow to between $500 billion and $3.7 trillion by 2030, the regulatory framework established by the Clarity Act will shape which stablecoin issuers and platforms are positioned to capture that growth. Critics of the current draft language argue that restrictions that do not apply to offshore competitors could accelerate adoption of unregulated alternatives among users who prioritise yield, ultimately reducing rather than protecting U.S. financial stability. That argument — which both Circle and Coinbase have made in their respective engagements with Senate staff — is likely to continue informing the bill's final language as lawmakers work toward a text that can achieve the Democratic support needed for Senate passage.
