Clarity Act markup advances with stablecoin yield ban that Bernstein says favors USDC
The compromise blocks deposit-like interest on passive balances but allows activity-based rewards tied to trading and payments.
U.S. lawmakers advanced the Clarity Act out of markup in a 15–9 vote on May 14, adding language that restricts deposit-like stablecoin interest while preserving rewards tied to real usage. Bernstein argues the design shuts down a stablecoin “rate arms race” and structurally advantages Circle’s USDC model as stablecoin supply and adjusted volumes hit records.
Key Takeaways
- The Clarity Act cleared markup 15–9 on May 14, 2026, adding language that bars deposit-like interest on passive stablecoin balances while permitting rewards tied to bona fide activity.
- Bernstein framed the compromise as an end to stablecoin yield competition and a relative tailwind for Circle, since USDC incentives are typically routed through partners and usage-linked programs rather than issuer-paid passive yield.
- Dollar-backed stablecoin supply topped $300 billion, with USDT and USDC together representing roughly 97% of outstanding supply.
- Adjusted stablecoin volumes were cited at about $15 trillion per month in April and roughly $100 trillion annualized, alongside a year-over-year rise in USDC’s adjusted-volume share from 41% to 60%.
Clarity Act Markup Adds a Stablecoin-Yield Ban With an Activity-Rewards Carve-Out
The Clarity Act advanced out of markup in a 15–9 vote on May 14, 2026, after lawmakers added compromise language aimed directly at how stablecoin issuers can incentivize holders.
The key constraint is a prohibition on paying interest that is “economically or functionally equivalent to a bank deposit” on passive stablecoin balances. At the same time, the text explicitly preserves rewards tied to bona fide activities, including trading, payments, and other usage-driven incentives.
For market structure, that distinction matters. It narrows the playbook for issuers trying to buy share by paying yield to anyone who simply parks balances, while leaving room for programs that look more like customer acquisition and payments rebates than deposit interest.
Why Bernstein Says the Language Tilts Toward USDC’s Partner-Led Distribution
Bernstein’s read is that the compromise reduces the viability of competing for stablecoin share purely by offering passive yield. If the rule is enforced as written, the “rate arms race” dynamic becomes harder to run at scale, particularly for smaller or less-liquid issuers that could previously outbid on headline rates.
Bernstein also positions Circle as a relative beneficiary because USDC does not directly pay passive yield on balances. Instead, partners such as Coinbase use distribution arrangements and rewards programs tied to USDC usage. That structure maps more cleanly onto the carve-out for activity-based incentives, at least on paper.
The unresolved edge is definitional. The bill’s language hinges on what regulators consider “economically or functionally equivalent” to deposit interest, and where they draw the line between usage rewards and yield in disguise.
Stablecoin Market Snapshot: $300B+ Supply and $100T Annualized Adjusted Volumes
The policy fight is landing into accelerating stablecoin usage metrics. Total dollar-backed stablecoin supply reached an all-time high above $300 billion as of Monday, with USDT the largest and USDC second. Together, the two represent roughly 97% of supply.
On activity, adjusted stablecoin volumes, which attempt to strip out bot activity, were cited at $15 trillion monthly based on April data, up from about $11 trillion in 2025. Annualized, total volumes were cited at roughly $100 trillion versus $55 trillion in 2025.
Bernstein’s analysis of Visa onchain data also cited a sharp share shift inside those adjusted volumes. USDC’s share was pegged as rising from 41% to 60% year-over-year, driven by gains in spot trading and wallet-to-wallet transactions. If those flows persist, the reward-rule boundary becomes a first-order competitive variable, not a footnote.
Legislative Hurdles and Market-Implied Odds for 2026 Passage
Even after markup, the bill is not law. Three stages remain: Senate Banking and Senate Agriculture must merge their versions into unified text, the Senate must clear a 60-vote floor threshold, and the final product must be reconciled with the House version that passed in July 2025.
Probability signals are split. Polymarket odds for Clarity Act passage in 2026 were cited at 62%. Coinbase Chief Legal Officer Paul Grewal was cited as expecting passage this summer, while GSR Chief Legal and Strategy Officer Joshua Riezman was cited as viewing the outcome as a 50/50.
The market sensitivity is likely to cluster around whether unified Senate text preserves the current yield language and how aggressively it defines “economically or functionally equivalent” interest.
Trading the Policy Path—Circle/Coinbase Sensitivity to the Yield Rule
The threshold that matters is whether the Senate’s unified text keeps the current bright line between passive balances and bona fide activity. If that line holds, the setup starts to look structural rather than narrative-driven because it constrains the simplest customer-acquisition lever competing issuers can pull.
I treat this as a live headline risk, not a done deal. The real test is whether lawmakers can clear the 60-vote Senate floor and then reconcile with the House without diluting the definition of deposit-like interest. If the language survives intact while USDC’s adjusted-volume share continues to track near the cited 60% and adjusted volumes stay near the $15T/month run-rate, the policy path becomes a practical distribution advantage for Circle and its partners rather than just another Washington storyline.
