The Complex Landscape of Stablecoin Regulation: A Comparative Analysis of Europe and the United States
Europe risks being relegated to a region overlooked for significant financial investments, with tokenized finance favored over traditional means.
In the rapidly evolving world of digital finance, stablecoins have emerged as a significant player, revolutionising the way transactions are conducted online. However, the regulatory landscape governing these digital assets is far from straightforward, particularly in Europe and the United States.
Europe: MiCA and the Challenges of Multi-Issuance
The Markets in Crypto-Assets Regulation (MiCA) came into force on December 30, 2024, establishing a unified legal framework for crypto-assets, including stablecoins. Classified as asset-referenced tokens (ARTs) and e-money tokens (EMTs), stablecoins are subject to strict requirements, such as full backing by high-quality liquid reserves within Europe, transparency through audits and periodic reports, and licensing/supervision by European financial authorities.
However, a key concern in Europe revolves around the multi-issuance of stablecoins—where the same stablecoins are issued simultaneously across multiple jurisdictions. The European Central Bank (ECB) fears that non-EU holders could redeem stablecoins via EU entities to circumvent fees or delays in their own jurisdictions, risking depletion of EU reserve assets and liquidity crises.
MiCA mandates that EMTs hold 30-60% of reserves in deposits with EU credit institutions, which could be strained by redemptions tied to multi-issuance scenarios. The EU is reluctant to adopt joint and several issuance models due to political resistance, which could have mitigated some multi-issuance risks.
There is a regulatory loophole since MiCA currently regulates only stablecoins issued within the EU but not those issued simultaneously outside the bloc by global firms. This allows for regulatory arbitrage and risk shifting, leaving EU entities potentially liable for global stablecoin redemptions without corresponding foreign reserves, thereby exposing EU financial stability to systemic risk.
United States: The GENIUS Act and Stablecoin Growth
The US has implemented its own federal stablecoin framework through the GENIUS Act, signed into law on July 18, 2025. This law establishes a federal regulatory regime that is somewhat aligned in spirit with MiCA but generally more lenient in certain areas. The US framework is expected to be operational within weeks from that date and aims to address risks around transparency, reserve management, and consumer protection.
Market projections anticipate significant growth in stablecoin supply in the US from about $230 billion in 2025 to $2 trillion by the end of 2028, reflecting increasing adoption in payments, remittances, and e-commerce. Major payment networks and merchants are integrating or exploring stablecoin usage, which highlights the importance of robust regulation.
Concerns and Implications
Both jurisdictions are grappling with balancing innovation in stablecoins against the systemic risks posed by multi-issuance, regulatory gaps, and cross-border liabilities. Financial stability risks, regulatory arbitrage, monetary sovereignty, licensing and supervision challenges are among the primary concerns.
Fears of a large-scale redemption may be largely irrational in a system where assets are matched 1:1 and highly liquid. Regulator intervention is unlikely as officials hold the ordoliberal view that it is not their job to force the market. Europe is debating whether to enable established dollar-denominated coins from the US, which the European Council described as 'oligopolistic', to be the 'cash leg' in Europe’s nascent tokenised finance market.
The multi-issuance argument in the regulation of stablecoins is resulting in contradictions and concerns about potential liquidity crises or runs on stablecoins. US policy via the Genius Act is moving 'on-off ramps' for distributed ledger technology finance to systemic components of digital finance, putting Europe at a disadvantage.
The fragmented sovereign bond market and the inadequacies in attempts to consolidate a single market for banking in Europe are hampering the growth of home-grown European stablecoins. OMFIF's public blockchain working group explores the integration of public blockchain systems into traditional finance.
Euro stablecoins face a fundamental challenge that dollar stablecoins do not: inadequate euro-denominated 'safe asset' sovereign bond markets to use as reserves. John Orchard is Chairman, and Katie-Ann Wilson is Managing Director of the Digital Monetary Institute at OMFIF. The reserves of stablecoins, especially those governed under MiCAR, are fully collateralised to ensure holders can be made whole at any time. The European Central Bank is concerned that multi-issuance will enable non‐EU holders to redeem stablecoins via EU entities, potentially draining EU reserve assets.
In conclusion, the current status of multi-issuance provisions for stablecoins shows a complex and evolving landscape both in Europe and the US, with distinct regulatory frameworks and significant concerns about financial stability and regulatory arbitrage. As the digital finance landscape continues to evolve, it is crucial for regulators in both regions to navigate these challenges to ensure a secure and robust digital finance ecosystem.
- The public insights about stablecoins, particularly regarding their impact on traditional financial systems, are valuable in understanding the complexities of their regulation.
- The technology behind stablecoins, such as blockchain and AI, contributes significantly to revolutionising digital transactions and financially inclusive events.
- The risk associated with stablecoins, especially multi-issuance, presents a challenge for policymakers in Europe and the United States, as it can potentially lead to regulatory gaps and cross-border liabilities.
- The Markets in Crypto-Assets Regulation (MiCA) in Europe and the GENIUS Act in the United States are two major policy initiatives designed to regulate stablecoin technology, with MiCA being more stringent on issues like reserve management and transparency.
- Digitalisation and stablecoins have the potential to transform general-news industries by streamlining transactions, improving financial access for the public, and promoting innovation in fintech.
- The sovereign finance systems in Europe and the US are closely watching the development of stablecoins, as they can influence the stability of their respective monetary ecosystems and impact broader political-economic relations.
- The debate around multi-issuance of stablecoins involves discussions on monetary sovereignty, licensing and supervision challenges, and the potential for regulatory arbitrage, making it a critical topic for policymakers, financial institutions, and the general public alike.
