The Senate Banking Committee has received more than 100 proposed amendments to its crypto market structure bill ahead of Thursday’s markup vote, signaling a heated clash over how to shape a federal framework for digital assets. A list obtained by POLITICO shows Democratic senators pushing amendments on stablecoin regulation, anti-corruption provisions, sanctions enforcement, and protections for software developers, while Republican lawmakers largely propose narrower revisions.
The bill, designed to create a federal regime that divides oversight of digital assets among U.S. market regulators, follows the House’s July passage of the CLARITY Act and comes after a January markup previously collapsed when Coinbase withdrew support over stablecoin reward restrictions.
At the center of the amendments is language governing stablecoin yield products. A revised version of the bill prohibits third-party platforms such as crypto exchanges from offering stablecoin rewards in a manner that is considered “functionally equivalent” to interest paid on bank deposits. Democratic Senators Jack Reed and Tina Smith have pressed to replace the standard of “equivalence” with a “substantially similar” test to tighten those restrictions, according to the POLITICO list. Banking groups have mounted renewed pressure to harden the language, arguing it could blunt the appeal of stablecoins and affect broader financial stability.
In a weekend letter circulated to lawmakers, American Banker Rob Nichols warned that the current draft could draw deposits away from traditional banks into stablecoins, potentially weakening lending activity and posing risks to financial stability.
Key takeaways
- No immediate price move reported. The amendments target regulatory scope and ethics provisions rather than market mechanics, with no clear, immediate market reaction documented.
- Catalyst: a wave of amendments ahead of markup. The 100-plus proposals touch stablecoins, sanctions enforcement, and protections for developers, signaling a high-stakes negotiation over a federal framework.
- Implication: regulatory clarity vs. blockages to innovation. The outcome will influence how digital assets are overseen, the role of banks in stablecoin markets, and protections around crypto-technology developers.
What drove the move
The amendment surge underscores ongoing tensions over the reach and safeguards of a federal crypto regime. Democratic lawmakers are pushing stricter rules on how yield-bearing stablecoins can be marketed and sold, aiming to prevent constructs they view as de facto bank deposits or as channels for circumventing existing financial regulations. The protests are particularly pointed around the concept of equivalence versus substantial similarity, with Reed and Smith advocating a tighter standard that could limit the way yield products are offered by non-bank entities.
Meanwhile, supporters of a lighter touch emphasize the need to avoid stifling innovation or pushing activity into less-regulated corners. The lobbying push from banking groups reinforces that view, arguing that the regulatory language should preserve traditional banking channels and financial-stability safeguards while still providing a clear framework for digital-asset participants.
Beyond stablecoins, the amendment package includes provisions on sanctions enforcement, institutional participation in crypto markets, and a proposal to restore the Justice Department’s National Cryptocurrency Enforcement Team, which was dismantled in 2023. The package also features new ethics provisions and potential safe harbors for software developers and infrastructure providers who do not hold customer funds, aligning with broader debates about innovation versus accountability in the crypto ecosystem.
Market reaction
Investors and industry observers have been watching how these debates could shape the regulatory landscape and the incentives for banks, exchanges, and developers. While the amendments themselves are largely policy instruments, the stakes lie in how quickly a unified federal framework could emerge and how stringent it would be. A senior figure familiar with the negotiations noted that the outcome may hinge on achieving consensus on ethics safeguards and conflicts of interest provisions, which have become a recurring sticking point.
What analysts are saying
Public-facing comments reflect a broad split in the Washington crypto dialogue. Democratic lawmakers have signaled that ethics rules must be robust before the bill gains support, with Kirsten Gillibrand arguing at Consensus Miami 2026 that Democrats would not back the legislation without strong safeguards. White House crypto adviser Patrick Witt has said the administration favors ethics rules that apply uniformly across government rather than targeting specific offices. Critics have warned that weak provisions could invite regulatory arbitrage and undermine consumer protection, while supporters contend that overly restrictive rules could hamper legitimate innovation and capital formation in the digital-asset space.
Senator Elizabeth Warren, the ranking member on the Banking Committee, asserted that the bill could worsen perceived conflicts of interest if officials can benefit from crypto ventures tied to policy decisions. On the other side of the aisle, Republican Grassley and Lummis are said to have reached alignments on enforcement concerns raised by prosecutors, though further changes are anticipated as the markup progresses.
Democratic Senator Catherine Cortez Masto has floated a safe-harbor provision shielding software developers from criminal liability when they are not registered money transmitters, a stance echoing provisions of the Blockchain Regulatory Certainty Act that crypto advocacy groups have supported for months. The bill’s language already clarifies that developers and infrastructure providers without control of customer funds should not be treated as money transmitters under federal law.
Additionally, amendments address sanctions enforcement, institutional participation in crypto markets, and Senator Andy Kim’s bid to restore the National Cryptocurrency Enforcement Team. With Republicans holding the committee majority, passage remains uncertain, and some GOP members have signaled they would withhold support unless certain provisions are amended or removed.
Bigger picture
The evolving draft highlights a broader policy debate about how far Congress should go to regulate a fast-moving digital-asset ecosystem. Key questions include whether a federal framework should explicitly separate the responsibilities of banking regulators and securities regulators, how to define and regulate stablecoins with yield features, and how to balance anti-crime objectives with the need to foster financial innovation. The outcome could influence banks’ exposure to crypto, the flow of deposits into stablecoins, and the operational risk profile of developers and infrastructure providers who support the ecosystem without handling customer funds.
As Congress advances the markup, investors will be watching for signals on the timeline to final passage, potential shifts in committee dynamics, and how the administration’s stance on ethics and conflicts of interest translates into enforceable provisions. Market participants will also monitor related policy developments in the House and any emerging compromises that could unlock a broader cross-chamber agreement on crypto regulation.
What to watch next: the committee markup this week, subsequent floor action in the Senate, and any evolving positions from the White House on ethics language and enforcement priorities. Investors will also keep an eye on how the amendments influence the regulatory roadmap for stablecoins and the balance between safeguarding financial stability and enabling innovation in digital assets.
