The GENIUS Act Explained: What US Stablecoin Regulation Means

The United States Is Finally Writing Stablecoin Rules

For years, the stablecoin industry operated in a regulatory grey zone. Issuers like Circle and Tether built products used by millions of people, moving hundreds of billions of dollars, without a dedicated federal framework governing how they should work.

That is changing. The GENIUS Act — the Guiding and Establishing National Innovation for US Stablecoins Act — represents the most serious attempt by the US Congress to create a comprehensive legal framework for payment stablecoins. It passed the Senate Banking Committee with bipartisan support and is widely expected to become law.

The implications are significant. For compliance officers, lawyers, and financial services executives, understanding what this bill requires — and what it leaves unresolved — is now essential.

“We worked with Congress to try to get a framework, a legal framework, for stable coins. Congress is again looking at a framework. Stable coins are a product, a digital product that could actually have fairly wide appeal and should contain consumer protections of the typical sorts and transparency.”

— Fed Chair Jerome Powell, quoted on Tokenized Ep 27

What the GENIUS Act Requires

The bill establishes a clear set of requirements for any entity that wants to issue payment stablecoins in the United States. These are not vague principles — they are specific, enforceable obligations.

1:1 Reserve Backing

Every payment stablecoin must be backed one-to-one by high-quality liquid assets. This means US Treasury bills, cash deposits at insured depository institutions, central bank reserves, or other assets deemed sufficiently safe and liquid. The days of ambiguous reserve disclosures are over. The bill demands that the assets backing a stablecoin are genuinely available to redeem every token at face value.

Monthly Reserve Attestations

Issuers must publish monthly attestations of their reserve holdings, conducted by registered public accounting firms. This goes beyond the voluntary “proof of reserves” reports that some issuers have published. Under the GENIUS Act, attestations become a legal requirement with regulatory consequences for non-compliance.

AML/KYC Compliance

Stablecoin issuers are explicitly brought under anti-money laundering and know-your-customer frameworks. This means compliance with the Bank Secrecy Act, sanctions screening, and suspicious activity reporting. For issuers that were already doing this voluntarily, the bill formalises existing practice. For others, it creates new obligations.

Federal vs State: The $10 Billion Line

One of the most consequential design choices in the GENIUS Act is how it divides regulatory authority between federal and state regulators.

Issuers with more than $10 billion in outstanding stablecoins must obtain a federal charter and be supervised by the Office of the Comptroller of the Currency (OCC) or the Federal Reserve. This captures the largest players — today, that would include Circle (USDC) and Tether (USDT).

Issuers below the $10 billion threshold can choose to be regulated at the state level, provided their state has adopted standards that are “substantially similar” to the federal requirements. This creates a dual-track system similar to how banking has historically worked in the United States.

But this dual structure raises serious questions — particularly around international recognition.

“A concern for me for a state level regulated stablecoin is, does that mean that state would have to agree to reciprocity arrangements with the UAE, the UK, the EU? Because what GENIUS does is it would enable a federal level agreement. How does that work if you're only state level regulated? That would destroy one of the massive use cases for stablecoins, which is cross border.”

— Elise Soucie, Executive Director, Global Digital Finance (Tokenized Ep 28)

This is not a theoretical concern. Stablecoins are inherently global instruments. A dollar-denominated stablecoin issued under Wyoming state law may struggle to gain recognition from regulators in the EU, UK, or Singapore if those jurisdictions only recognise federally-supervised issuers.

The OCC Opens the Door for Banks

Running in parallel with the GENIUS Act, the OCC has issued guidance clarifying that nationally-chartered banks can engage with crypto assets — including holding stablecoins on their balance sheets, providing custody services, and participating in blockchain networks.

“With that regulatory clarity through things like the GENIUS bill and OCC allowing banks to hold stablecoins on their balance sheets, it looks like the states want to get involved as well.”

— Chris Harmse, BVNK (Tokenized Ep 24)

This is a significant shift. Under the previous administration, banks were effectively discouraged from touching crypto through informal guidance and supervisory pressure. The OCC's new posture — combined with Powell's public comments about loosening restrictions — creates a path for traditional banks to become stablecoin issuers, custodians, or service providers.

“We took a pretty conservative perspective on the guidance and rules we imposed on banks. I think there'll be some loosening of that, and we'll try to do it in a way that preserves safety and soundness but permits and fosters appropriate innovation.”

— Fed Chair Jerome Powell, quoted on Tokenized Ep 27

For financial services executives, this changes the competitive landscape. Banks that were sitting on the sideline now have a clear legal path to participate. The question is no longer whether banks can issue or hold stablecoins, but how quickly they choose to do so.

International Reciprocity

The GENIUS Act includes provisions for recognising foreign stablecoin issuers, provided they meet standards comparable to the US framework. This is important because stablecoins are a global market. USDC and USDT are used extensively outside the United States — for remittances, trade settlement, and as a store of value in countries with unstable currencies.

The reciprocity framework would allow the US to negotiate mutual recognition agreements with other jurisdictions. If the EU's MiCA framework is deemed “substantially similar,” a euro-denominated stablecoin regulated under MiCA could potentially operate in the US market, and vice versa.

But as Elise Soucie points out, this only works cleanly at the federal level. If a stablecoin is regulated by a single US state, the mechanics of international reciprocity become extremely complicated. Does Wyoming negotiate a bilateral agreement with the UK? The question answers itself.

Wyoming's State-Level Experiment: WYST

Wyoming has been one of the most proactive US states in crypto regulation. Its latest initiative is WYST, a state-issued stablecoin that would be backed by US Treasury holdings and managed by the state government.

WYST represents an interesting test case for the state-level track under the GENIUS Act. If Wyoming can demonstrate that a state-regulated stablecoin can meet the same standards as a federally-chartered issuer, it strengthens the case for the dual-track approach. If it struggles to gain international recognition or institutional adoption, it illustrates the limits of state-level regulation for an inherently global product.

For now, WYST remains small relative to the major private-sector issuers. But it is being watched closely as a precedent for how states might participate in the stablecoin market.

Impact on Existing Players

The GENIUS Act will affect different market participants in different ways.

Circle (USDC)

Circle is arguably the best-positioned incumbent. It already publishes monthly reserve attestations from a Big Four accounting firm, holds reserves primarily in US Treasuries and cash, and has built its compliance infrastructure around the assumption that federal regulation was coming. The GENIUS Act largely codifies what Circle is already doing.

Tether (USDT)

Tether faces a more complex path. As the largest stablecoin by market capitalisation, it would fall firmly above the $10 billion federal threshold. But Tether is domiciled outside the United States and has historically been less transparent about its reserve composition. The GENIUS Act's requirements for monthly attestations, AML compliance, and reserve quality will require either significant operational changes or a decision to operate primarily outside US jurisdiction.

Banks

Traditional banks are the big unknown. JPMorgan already operates JPM Coin for institutional settlement. With the OCC's new guidance and the GENIUS Act's framework, any nationally-chartered bank could theoretically issue its own payment stablecoin. The infrastructure costs are significant, but for large banks, stablecoins represent a potential new revenue stream and a way to maintain relevance in a changing payments landscape.

What This Means for Businesses Using Stablecoins

If you are a business that already uses stablecoins — for treasury management, cross-border payments, payroll, or settlement — the GENIUS Act provides regulatory clarity that reduces legal risk. Working with a federally-regulated stablecoin issuer gives you a clear compliance posture that is defensible to auditors, regulators, and boards.

If you are a business considering stablecoins for the first time, the framework makes the decision easier. The ambiguity that previously made legal and compliance teams nervous is being replaced by a defined regulatory regime with clear rules about reserve backing, consumer protection, and issuer obligations.

Key considerations for businesses:

• Issuer selection matters more than ever. Choose stablecoins from issuers that will be federally regulated or that operate under state frameworks with clear “substantially similar” standards.
• Cross-border use cases need federal-level issuers. If your stablecoin use involves international counterparties, state-level regulated stablecoins may face recognition challenges in foreign jurisdictions.
• Bank-issued stablecoins are coming. If your business already has banking relationships, your bank may soon offer stablecoin products directly. This could simplify compliance and reduce counterparty risk.
• Reserve transparency is now a legal requirement. Use the monthly attestation reports to verify that the stablecoins you hold are genuinely backed. This is no longer optional due diligence — it is a regulatory expectation.

The Path Forward: What's Still Uncertain

The GENIUS Act is a major step, but it does not resolve everything. Several important questions remain open.

Interest-bearing stablecoins. The current bill focuses on payment stablecoins — those designed to maintain a stable value and facilitate transactions. It does not clearly address stablecoins that pay yield to holders. Whether interest-bearing stablecoins are securities, bank deposits, or something else entirely is still being debated.

Algorithmic stablecoins. The GENIUS Act is designed around fully-reserved, asset-backed stablecoins. Algorithmic models — which maintain their peg through protocol mechanisms rather than reserves — are not addressed. After the Terra/Luna collapse, there is limited appetite to regulate them into existence, but the gap remains.

State-level implementation. The “substantially similar” standard for state regulation will need to be defined and enforced. Which states meet the bar? Who decides? How quickly can states that want to participate update their frameworks? These details will take time to work out.

Enforcement coordination. With the OCC, Federal Reserve, state regulators, FinCEN, and potentially the SEC all having some role, the coordination mechanisms are not yet clear. Businesses need a single, predictable compliance framework — not overlapping and potentially contradictory requirements from multiple agencies.

Despite these open questions, the direction of travel is clear. The United States is moving from a posture of regulatory ambiguity to one of defined rules. For businesses, institutions, and compliance professionals, the time to understand this framework is now — not after the bill becomes law.
