Executive Summary
The United States has now made its position on stablecoins explicit. The GENIUS Act, signed on July 18 2025, establishes a federal licensing regime for payment stablecoins: permitted issuers only, one-to-one high-quality liquid reserves, par redemption, and supervisory oversight.
As of January 23 2026, global stablecoin supply stands at roughly $309–311 billion, following a mid-January all-time high of $311.332 billion. 2025 transaction volumes reached approximately $33 trillion, confirming that stablecoins are no longer a marginal crypto use case.
The critical shift, however, is not statutory but operational. In the US, stablecoin discipline is enforced primarily through banking access, custody permissions, and supervisory leverage, not through blockchain-specific rules. This analysis builds on the core thesis that stablecoins are balance sheets, not software, extending it into a US-first examination of how enforcement is applied in practice.
1. The US Is Not Late — It Is Methodical
The claim that the US was “behind” on stablecoin regulation misunderstands how American financial control works.
Washington historically enforces discipline through existing financial plumbing, not bespoke regimes. Ambiguity was tolerated while stablecoins were small. Once supply crossed systemic relevance—now well past $300 billion—the plumbing was activated.
Recent signals include a Notice of Proposed Rulemaking approved in December 2025 by the :contentReference[oaicite:0]{index=0}, outlining how FDIC-supervised institutions may issue stablecoins via subsidiaries, alongside conditional approvals issued by the :contentReference[oaicite:1]{index=1} for national trust banks focused on custody, reserve management, and issuance.
The US did not lack a framework. It lacked urgency—until scale forced its hand.
2. What the GENIUS Act Actually Does (and Doesn’t)
The GENIUS Act provides clarity and constraint, not innovation mandates.
It clearly establishes that stablecoin issuance is a regulated financial activity, limits Permitted Payment Stablecoin Issuers (PPSIs) to supervised bank subsidiaries, federally qualified non-banks, or state-qualified entities under substantially similar regimes, mandates one-to-one reserves in US dollars or highly liquid assets, requires par redemption and regular disclosures, and explicitly prohibits implying FDIC insurance.
This structure reinforces the central role of the issuer as the primary risk-bearing entity, as detailed in What Is a Stablecoin Issuer?.
What GENIUS deliberately avoids is equally important. It does not impose protocol-level rules, mandate innovation outcomes, or reclassify qualifying payment stablecoins as securities or commodities. It is an issuer licensing and balance-sheet regime, designed to plug stablecoins directly into existing supervision.
3. The Real Enforcement Layer: US Banking Access
Stablecoins depend on US dollar infrastructure: reserve accounts, payment rails, Treasury settlement, and correspondent banking. All of this sits under Federal Reserve, FDIC, and OCC supervision.
Bank access is the lifeline. Accounts can be restricted or frozen under AML or sanctions controls, liquidity stress, or supervisory direction. Non-US issuers routing dollars through US correspondents inherit US oversight by default. Bank subsidiaries issuing stablecoins face prudential standards around capital, liquidity, and risk management.
The mechanics of reserve composition and liquidity access under stress are examined in What Are Stablecoin Reserves (and Why They Matter)?.
Reality check:
In the US, stablecoins live or die at the bank account—not on-chain.
4. Custody as the US Kill Switch
Custody is where US leverage becomes immediate.
Scale stablecoins rely on a small number of qualified custodians, increasingly structured as OCC-chartered national trust banks or bank-affiliated custodial entities. This concentration enables rapid enforcement through AML freezes, supervisory directives, or jurisdictional restrictions—without new crypto-specific rules.
These enforcement dynamics are explored further in Custodianship Models for Stablecoins, which shows how legal control and jurisdiction dominate outcomes during stress.
Custody does not merely safeguard assets. In the US system, it controls survival.
5. Yield: Why the US Closes the Door Harder Than Europe
US policymakers view yield-bearing stablecoins as deposit substitution, shadow banking, and credit intermediation.
Under the GENIUS baseline, direct or passive yield to holders is prohibited. Draft amendments to the CLARITY Act circulated in January 2026 go further, targeting affiliate-based yield schemes and passive rewards that accrue solely from holding.
In mid-January 2026, :contentReference[oaicite:2]{index=2} publicly withdrew support for a Senate Banking Committee draft of CLARITY, arguing that proposed language would amount to a de-facto ban on stablecoin rewards, including indirect models. Banking groups countered that such rewards erode deposits and financial stability. Regardless of outcome, the signal is clear.
In the US, yield isn’t a feature — it’s a classification trigger.

6. Non-US Issuers Are Still US-Constrained
Stablecoin domicile is flexible. Dollar exposure is not.
Even non-US issuers remain tied to the US through dollar-denominated reserves, US correspondent banking, custody concentration, Treasury settlement, and US-anchored liquidity and pricing.
You can issue offshore.
You cannot domicile away from the dollar.
7. What Survives the US Regime (2026–2028)
As GENIUS rules finalise and supervisory enforcement matures, likely survivors include bank-issued stablecoins via subsidiaries, tokenised deposits with narrow supervised mandates, OCC-chartered national trust structures, and scaled PPSIs with robust US banking relationships.
Likely losers include thin-margin issuers, yield-dependent models, complex offshore custody webs, and regulatory arbitrage strategies.
Base-case forecast:
Roughly 60–70% of smaller or non-compliant issuers will consolidate, exit, or be regulated out of viability by 2028.
8. How This Reshapes the Global Stablecoin Map
US enforcement through plumbing raises standards globally.
UK alignment accelerates via the FCA gateway opening in September 2026. EU MiCA enforcement peaks through 2026. Arbitrage windows narrow as global issuers conform to US dollar expectations.
Final assertion:
The US doesn’t need to regulate the world. It only needs to regulate the dollar.

FAQ
How does US stablecoin enforcement differ from the EU or UK?
The US enforces through banking and custody infrastructure, the EU through harmonised rules under MiCA, and the UK through functional supervisory discretion.
What is the current status of the GENIUS Act (Jan 23 2026)?
Rulemaking is active, with FDIC proposals open for comment and OCC trust approvals already issued.
Will yield survive in US stablecoins?
Direct and passive yield is prohibited; indirect models face tightening scrutiny.
What is the stablecoin market size in January 2026?
Approximately $309–311 billion, following an ATH of $311.332 billion in mid-January.
