U.S. Senators Push Treasury to Preserve State Oversight in GENIUS Act Stablecoin Rules
LTB A bipartisan group of U.S. senators is pressing Treasury Secretary Scott Bessent to keep state regulators meaningfully involved as the U.S. writes the rules for stablecoins under the GENIUS Act fight. The fight now is not whether stablecoins get regulated — they will — but whether states get a real lane or just a decorative plaque on the federal wall.
- Senators want state oversight preserved in final GENIUS Act rules
- Treasury’s draft principles are seen as too vague on certification timing
- Issuers under $10 billion can choose state regulation if standards are “substantially similar”
- USDt, USDC, and USDS are too large for the state route
- AML, sanctions, and Bank Secrecy Act rules are the next big battleground
On June 16, a bipartisan group led by Senator Cynthia Lummis sent a letter to Bessent asking Treasury to ensure the final GENIUS Act framework “preserves and promotes State participation.” The signers include Kirsten Gillibrand, Bill Hagerty, Kevin Cramer, Pete Ricketts, Angela Alsobrooks, and Catherine Cortez Masto — a roster that tells you this isn’t just partisan posturing. When lawmakers from both parties start giving Treasury side-eye, the bureaucrats probably stepped on a rake.
Why states are fighting for a seat
The dispute centers on Section 4(c) of the GENIUS Act, which senators say gives states a pathway to certify their own stablecoin regimes. In plain English, that means a state could run its own approved framework for supervising certain stablecoin issuers instead of forcing every smaller issuer into one federal mold.
That matters because the U.S. has long used a dual banking system — a structure where both federal and state regulators supervise parts of the financial system. It’s messy, sure. It’s also one of the reasons financial regulation in America hasn’t been fully swallowed by Washington’s appetite for central control. The senators’ point is simple: if Congress wrote states into the law, Treasury shouldn’t quietly write them out through implementation.
The complaint is not that Treasury is regulating stablecoins. It’s that Treasury’s proposed state-level principles reportedly do not clearly spell out how states apply, how reviews will work, and when certification decisions will be made. That lack of clarity matters a lot. If the process is vague, slow, or front-loaded into a short early window, states may lose the ability to build and maintain a live regulatory pathway.
That is why the senators pushed back against the idea of a “one-time window” for state certification. If that becomes the default, state authority turns into a trapdoor: technically there, practically useless. That would be a win for centralizers, a win for regulatory uniformity, and a loss for anyone who still believes competition between state and federal regimes can produce better outcomes.
What the GENIUS Act actually allows
The GENIUS Act creates a federal stablecoin framework while leaving room for states to supervise smaller issuers. The threshold is important: issuers with no more than $10 billion in outstanding issuance can choose state regulation if the state’s regime is “substantially similar” to the federal framework.
“Substantially similar” is doing a lot of heavy lifting there. It does not mean states can invent their own cowboy version of stablecoin rules and hope nobody notices. It means they need a framework close enough to federal standards on reserves, supervision, and consumer protections to satisfy Treasury. That’s the compromise: state flexibility, but not a free-for-all.
For newer readers, a stablecoin is a digital token designed to hold a stable value, usually by being backed by dollars, cash equivalents, or other reserves. The idea is to combine crypto’s speed and programmability with the boring but useful predictability of traditional money. The catch, as always, is that stability is only as real as the reserves, controls, and governance behind it. If those are flimsy, the “stable” part becomes marketing copy.
The state pathway is mainly for smaller players. The giants are already too big for it. Tether’s USDt, USDC, and USDS are all above the $10 billion threshold, which means the state option is not designed for the sector’s biggest names. This is really about the next tier of issuers, the firms trying to grow without getting swallowed whole by federal compliance machinery from day one.
That said, there’s a counterpoint worth taking seriously: Treasury and other federal regulators will argue that a patchwork of state regimes could invite regulatory arbitrage, inconsistent enforcement, and a race to the bottom. That concern is not made up. America’s financial system does not need fifty conflicting stablecoin rulebooks and a compliance department with a migraine. The real question is whether Treasury can preserve state participation without turning oversight into a casino of loopholes.
The timing fight may decide the outcome
Treasury opened public comments on the proposed state-level principles in April, with the comment period running 60 days from publication in the Federal Register. That likely means the window closed in early June. The senators’ letter arrived after that deadline, which is a polite way of saying the political pressure is now hitting as Treasury moves toward the final rule.
That timing matters. Once Treasury finalizes the framework, the practical shape of stablecoin regulation could be locked in for years. If the agency sets the bar in a way that’s hard for states to clear, the federal government effectively wins by default — not through Congress, but through implementation drift. That’s how a “dual” system becomes single-track without anyone admitting that’s what happened.
The senators want written guidance on the mechanics:
- how states can apply
- how reviews will work
- when certification decisions will be made
That’s not bureaucratic nitpicking. Those procedures determine whether a state path is real or just theoretical. A right without a process is basically a promise on a napkin.
The next battle: AML, sanctions, and surveillance
Stablecoin rulemaking is not stopping at reserve standards and charter questions. Treasury is also working on separate GENIUS Act rules for illicit finance controls. That proposal would treat permitted stablecoin issuers as financial institutions under the Bank Secrecy Act and require sanctions compliance programs.
For anyone unfamiliar, the Bank Secrecy Act is the U.S. law that underpins much of the country’s anti-money-laundering regime. It forces financial institutions to monitor transactions, keep records, and report suspicious activity. In stablecoin land, that translates into more surveillance, more compliance costs, and less room for sloppy operations.
“permitted payment stablecoin issuers as financial institutions for Bank Secrecy Act purposes”
That approach may help legitimize stablecoins in the eyes of regulators and institutions. It may also make the system more usable for mainstream finance. But there’s a hard edge here: once stablecoin issuers are treated like full-blown financial institutions, the sector inherits a lot of the same friction that has made legacy finance slow, expensive, and annoying in the first place. Congrats, you made the rails. Now enjoy the paperwork.
Not everyone in crypto is applauding. Hyperliquid and Paradigm have both asked Treasury to narrow the proposed AML and sanctions duties for stablecoin issuers. Their concern is understandable: if the rules are too broad, they could turn stablecoin issuers into surveillance arms of the state, forcing smaller innovators to either absorb major compliance costs or get squeezed out entirely.
There’s a real trade-off here. Strong compliance can reduce abuse and make stablecoins more acceptable for businesses, institutions, and everyday users. But overreach can also choke competition and push innovation toward a few massive incumbents who can afford armies of lawyers and compliance officers. That’s not decentralization. That’s just fintech with a government-issued leash.
Traditional finance is moving in anyway
While lawmakers argue over jurisdiction, traditional finance is already circling the stablecoin opportunity. State Street recently launched a stablecoin reserve money market fund aimed at the GENIUS Act framework, showing that legacy finance sees real business value in the infrastructure around stablecoins even if it still likes to clutch its pearls about crypto risk.
New York DFS has also proposed updates to its stablecoin regime to align with the GENIUS Act. That’s a sign states are not just defending turf for ego’s sake. They’re adapting, building, and trying to remain relevant in a market that could become a serious payments layer if regulators don’t smother it with overcooked compliance spaghetti.
And there’s more pressure in the background. The FDIC is facing GAO pressure over coordination on blockchain risk, a reminder that the regulatory maze is not limited to Treasury. Banking regulators, watchdogs, and lawmakers are all trying to define their slice of the stablecoin pie. Nobody wants to be the agency left holding the bag if something blows up.
Why this fight matters for stablecoin regulation
This is bigger than one letter and one rulemaking. The outcome will shape whether the U.S. stablecoin framework encourages competition between state and federal oversight or smothers it under centralized control. Smaller issuers may benefit from a state path that is faster, more flexible, and closer to the realities of local supervision. If that path gets narrowed into a one-off certification sprint, the market will tilt toward bigger players and heavier federal supervision.
There’s a legitimate argument for centralization. Stablecoins can move fast, scale quickly, and create cross-border risk. Bad actors love weak controls, and the government has every reason to care about sanctions evasion, money laundering, and consumer harm. Anyone pretending otherwise is selling fairy dust with a blockchain sticker on it.
But there’s also a legitimate case for keeping states in the game. A living dual system can support experimentation, competition, and a wider set of market entrants. That’s especially relevant for smaller issuers that may not want — or survive — immediate federal-grade overhead. If states can certify their regimes on an ongoing basis, they can act as a real counterweight rather than a historical footnote.
The real test for Treasury is whether it can write rules that protect consumers and shut down abuse without turning the GENIUS Act into a centralization machine. If state certification is preserved in practice, not just in theory, the framework could become a workable model for stablecoin oversight in the U.S. If not, Washington will have pulled off another neat trick: promising decentralization through legislation and then centralizing it through paperwork.
Key questions and takeaways
What is the main issue in the GENIUS Act fight?
Whether state regulators will have a meaningful, ongoing role in stablecoin oversight or get squeezed out by Treasury’s implementation.
What is Section 4(c) of the GENIUS Act?
It is the part of the law senators say gives states a pathway to certify their own stablecoin regulatory regimes.
Why are senators asking about timelines and procedures?
Because state certification means little if Treasury doesn’t clearly explain how states apply, how reviews happen, and when approvals are decided.
What does “substantially similar” mean?
It means state rules must closely match the federal framework, not wander off into random experimentation.
Who can use the state pathway?
Stablecoin issuers with no more than $10 billion in outstanding issuance, if their state regime is approved.
Why don’t USDt, USDC, and USDS use the state route?
They’re all above the $10 billion threshold, so they fall outside the smaller-issuer state option.
What new compliance rules are coming?
Treasury is also preparing rules that would apply Bank Secrecy Act and sanctions compliance obligations to permitted stablecoin issuers.
Why does this matter to crypto users and builders?
Because these rules will shape who can issue stablecoins, how costly it is to comply, and whether the U.S. market stays competitive or gets choked by centralized control.
