Introduction: Why stablecoin regulation matters now
Stablecoins are cryptocurrencies designed to maintain a stable value by being pegged to an asset such as the US dollar, euro, or commodities like gold. Unlike volatile tokens such as Bitcoin or Ethereum, stablecoins are meant to serve as reliable mediums of exchange and stores of value. They now account for more than $160 billion in circulation globally, supporting everything from cross-border payments to decentralized finance (DeFi) protocols.
In 2025, stablecoins have moved from the edges of crypto into mainstream financial discussions. Governments are responding, with the US passing sweeping legislation in the form of the GENIUS Act of 2025, which introduces comprehensive stablecoin regulation.
The act provides a framework for payment stablecoin issuers and establishes a stablecoin certification review committee to oversee stablecoin activities. Stablecoin issuers must comply with the Bank Secrecy Act and the Investment Company Act, ensuring that the emerging stablecoin market operates within a regulated environment.
Key takeaways
- Stablecoins are now central to digital finance, with $160 billion in circulation.
- The US GENIUS Act of 2025 sets federal standards on reserves, licensing, and transparency.
- The Bank of England’s proposed ownership cap is among the strictest rules worldwide.
- Regulation aims to protect consumers and markets but could slow innovation.
- Global businesses must prepare for a fragmented regulatory landscape.
Moreover, the act designates the Comptroller of the Currency as the primary federal payment stablecoin regulator, while allowing state payment stablecoin regulators to operate under certain guidelines.
This regulatory landscape not only impacts stablecoin holders but also defines the roles of permitted payment stablecoin issuers, which must follow strict requirements for issuing payment stablecoins.
The passage of the GENIUS Act signals a significant shift in how stablecoins in the US will be managed, as federal stablecoin regulators work alongside state stablecoin authorities to create a balanced ecosystem.
As we move forward, understanding the implications of stablecoin regulation will be crucial for investors, businesses, and policymakers alike, as they navigate this rapidly evolving financial landscape.
What happened: Key regulatory moves in 2025
The United States: GENIUS Act of 2025
The GENIUS Act represents the first comprehensive federal law governing stablecoins in the US. Passed by Congress and signed into law by President Trump in July 2025, the Act lays down clear requirements:
- Reserves: Issuers must hold high-quality liquid assets, such as US Treasuries or cash, equal to 100% of outstanding stablecoins.
- Licensing: Only federally permitted institutions, such as banks or approved entities, may issue payment stablecoins.
- Oversight: Agencies including the Federal Reserve, OCC, FDIC, and FinCEN will coordinate supervision.
- Consumer protection: Issuers must disclose reserve holdings, redemption policies, and audit results.
Supporters argue this will boost trust, attract institutional investors, and reduce systemic risks. Critics warn that the law could stifle smaller issuers and push innovation offshore.
The GENIUS Act requires that no permitted payment stablecoin issuer may engage in the issuance of a payment stablecoin unless they comply with strict reserve and disclosure requirements.
When President Trump signed the GENIUS Act, it marked the first time federal law clearly defined what a “payment stablecoin” is, and the act defines a “digital asset” in detail. Under its provisions, an issuer is subject to regulation whether it is a state qualified stablecoin issuer, a foreign payment stablecoin issuer, or one of the federal qualified payment stablecoin issuers.
The Act makes clear that a nonbank stablecoin provider cannot engage in payment stablecoin issuance or sell a payment stablecoin to a person located in the US unless the payment stablecoin is issued by a permitted entity. Likewise, a foreign payment stablecoin issuer unless licensed by a foreign payment stablecoin regulator cannot distribute tokens in the US.
The law ties into the Bank Holding Company Act and the Commodity Exchange Act, bringing stablecoin oversight in line with existing financial statutes. It also establishes primary federal stablecoin regulators who will coordinate with state stablecoin regulators and international bodies.
The activities of permitted payment stablecoin issuers, from maintaining a payment stablecoin reserve to managing the sale of a payment stablecoin, fall under both federal payment stablecoin regulators and state-level regulatory oversight.
By requiring that stablecoin issuers must hold reserves and that stablecoin issuers must comply with disclosure rules, the Act aims to strengthen the stablecoin industry, improve stablecoin usage, and limit risks. Importantly, it prohibits a payment stablecoin issuer from issuing or conditioning services unless consistent with act or any regulation adopted by the applicable primary federal payment stablecoin regulator.
In short, when Trump signed the GENIUS Act, the US set the foundation for global standards, ensuring that stablecoin issuers and foreign entities can only operate if they meet the same high bar of compliance and transparency.
The United Kingdom: Bank of England’s proposed cap
In contrast, the Bank of England has proposed strict ownership limits on stablecoins. Individuals and businesses could only hold a capped amount of stablecoins to avoid sudden capital flight from traditional banks into digital assets. The central bank argues the move will preserve financial stability and protect bank deposits.
Crypto groups and fintech companies strongly oppose the plan, warning it will block adoption, disadvantage UK startups, and drive activity to friendlier jurisdictions.
Europe and beyond
The EU’s Markets in Crypto-Assets Regulation (MiCA) took effect in 2024, requiring issuers to maintain strong reserves and register with regulators. Other countries, including Singapore and Canada, are drafting their own frameworks. This patchwork of rules means companies operating internationally must prepare for compliance in multiple jurisdictions.
Why it matters: Stablecoin Regulation Implications for finance and crypto markets
Stablecoins underpin billions of dollars in daily trading volume. They are used as payment rails, trading pairs on exchanges, and settlement instruments in global commerce. Regulation carries wide-ranging consequences:
- For consumers: Clear rules could increase trust, reduce the risk of collapse like TerraUSD in 2022, and ensure redemption rights.
- For businesses: Merchants accepting stablecoins face new compliance requirements but may benefit from lower transaction costs and faster cross-border payments.
- For banks: Regulation could force collaboration with stablecoin issuers or even open the door for banks to issue their own tokens.
- For investors: Regulatory clarity may reduce uncertainty and attract institutional capital, but restrictive rules could also curb liquidity.
The balance is delicate. Too much oversight could drive innovation abroad, while too little could risk financial crises.
Context and risks: What history tells us
Stablecoin regulation has been on the radar since Facebook’s proposed Libra (later Diem) project in 2019 triggered global concern. The collapse of algorithmic stablecoin TerraUSD in 2022, which wiped out $40 billion in value, added urgency. Since then, governments have prioritized consumer protection, anti–money laundering safeguards, and systemic stability.
The GENIUS Act brings the US closer to Europe’s MiCA, but the UK’s ownership cap makes it an outlier. Risks include:
- Regulatory arbitrage: Companies shifting operations to less restrictive countries.
- Implementation gaps: Multiple US agencies must coordinate effectively, or enforcement could be inconsistent.
- Innovation slowdown: Strict rules could deter startups from experimenting with new models of digital money.
What to watch next
- Bank of England consultations: Will industry lobbying force a rethink of the proposed cap?
- US enforcement: How regulators like the Federal Reserve and OCC coordinate implementation of the GENIUS Act.
- Industry adaptation: Whether major issuers like Circle (USDC) or Tether change their reserve structures or relocate jurisdictions.
- CBDC competition: How central bank digital currencies may coexist—or compete—with private stablecoins.
- Global alignment: Whether international bodies like the IMF or FSB push for harmonized rules to reduce regulatory fragmentation.

Conclusion about Stablecoin Regulation
The regulation of stablecoins is increasingly crucial as their adoption grows in the digital asset landscape. With the implementation of the Stablecoins Act, the framework for stablecoin legislation is becoming clearer. The final regulations implementing the act aim to provide a structure for permitted payment stablecoin issuers, ensuring compliance with both federal and state laws.
The federal payment stablecoin regulator may oversee these activities, establishing a consistent approach across jurisdictions.
Furthermore, the Financial Crimes Enforcement Network (FinCEN) plays a vital role in addressing potential risks associated with stablecoin use, particularly concerning financial crimes.
A permitted payment stablecoin issuer must adhere to these regulations to mitigate risks, thus fostering a safer environment for digital transactions. The act defines a “digital asset”, which clarifies the status of payment stablecoins in the evolving market.
As various states begin to implement their own stablecoin regulatory regimes, it is essential for stakeholders to stay informed about compliance requirements. The enactment of the act is expected to streamline processes for issuing a payment stablecoin, allowing for innovation while maintaining consumer protection.
Moreover, the Genius Act provides additional guidelines for the regulation of foreign stablecoin activities, ensuring that all stablecoin issuers operate within a safe framework.
In conclusion, the landscape of stablecoin regulation is complex yet promising. As we continue to witness advancements in legislation, the balance between innovation and regulation will be crucial to the sustainable growth of the digital currency ecosystem.
Frequently Asked Questions: Stablecoin Regulation (2025)
1) What is a “payment stablecoin” under the U.S. GENIUS Act?
Under S.1582 (the GENIUS Act), a payment stablecoin is a digital asset issued for payment or settlement that must be redeemable for a fixed amount (e.g., $1). The bill establishes a federal framework for these tokens. :contentReference[oaicite:0]{index=0}
2) Who can issue payment stablecoins in the U.S., and what reserves are required?
Only “permitted payment stablecoin issuers” (PPSIs)—such as approved banks or licensed entities—may issue payment stablecoins. Issuers must maintain 100% reserves in high-quality liquid assets (e.g., cash and short-term U.S. Treasuries) and make regular public disclosures of reserve composition. :contentReference[oaicite:1]{index=1}
3) Can U.S. stablecoin issuers pay interest on coins?
No. Legal analyses of the GENIUS Act indicate payment stablecoins are non-interest-bearing; the law is designed to avoid deposit-like competition with banks, while still permitting compliant issuance and redemption at par. :contentReference[oaicite:2]{index=2}
4) When did the GENIUS Act become law, and what’s next?
President Trump signed the GENIUS Act in July 2025. Treasury has already begun implementation steps (e.g., public requests for comment to inform rulemaking and supervision). Expect additional guidance and technical standards from federal agencies. :contentReference[oaicite:3]{index=3}
5) How does the U.S. approach compare to the EU’s MiCA rules?
MiCA is fully in force for stablecoins (ARTs/EMTs) in the EU, requiring authorization, disclosures, capital, and reserve/audit obligations. The U.S. GENIUS Act similarly requires 1:1 reserves and federal supervision, but the EU regime is pan-European and applies uniformly across Member States. :contentReference[oaicite:4]{index=4}
6) What is the UK proposing with “ownership caps” on stablecoins?
The Bank of England has proposed caps on holdings of systemic stablecoins—£10k–£20k per individual and £10m for businesses—to mitigate deposit flight risk. Industry groups argue this would be hard to enforce and could hinder UK innovation. The proposal is under consultation. :contentReference[oaicite:5]{index=5}
7) Can foreign stablecoin issuers operate in the U.S. market?
Yes, but foreign issuers must meet the GENIUS Act’s requirements and any applicable U.S. licensing/supervisory standards before offering or selling coins to U.S. persons. Legal guidance emphasizes capital, liquidity, disclosures, and compliance obligations for any issuer serving U.S. users. :contentReference[oaicite:6]{index=6}
8) Are stablecoins treated as securities or commodities?
The GENIUS Act creates a bespoke category for “payment stablecoins” with banking-style oversight. While other crypto assets may fall under securities or commodities law, payment stablecoins issued by permitted issuers are intended to be regulated under the Act’s prudential framework rather than as securities/commodities by default. (Specific classification still depends on facts and agency coordination.) :contentReference[oaicite:7]{index=7}
9) What disclosures should I expect from issuers?
Issuers must publish regular, standardized reserve disclosures (e.g., monthly) and provide clear redemption terms so users can convert 1:1 at par. These transparency requirements are central to the GENIUS Act’s consumer-protection goals. :contentReference[oaicite:8]{index=8}
10) Do these rules change market dynamics among leading stablecoins?
Yes. The new federal framework has prompted established players to align products with U.S. requirements and spurred new, U.S.-regulated entrants—shifting competitive dynamics with potential implications for market share, listings, and liquidity. :contentReference[oaicite:9]{index=9}
