How US and EU Stablecoin Rules Are Splitting the Global Market

Source: ETHNews Original Title: Here is How US and EU Stablecoin Rules Are Quietly Splitting the Global Market Original Link: A new report released on December 4, 2025 by blockchain security firm CertiK argues that diverging US and EU regulatory frameworks for stablecoins are creating two separate global “liquidity pools.”

The analysis suggests that instead of converging toward a unified, interoperable stablecoin market, the world’s two largest economic blocs are moving in opposite regulatory directions, a shift that could reshape capital flows, institutional participation, and where major issuers choose to operate.

US Framework Favors Innovation and Dollar Expansion

CertiK’s report highlights that the GENIUS Act, signed into law in July 2025, has become the centerpiece of America’s stablecoin strategy. The law imposes strict reserve requirements, bans yield-bearing stablecoins, and provides federal oversight for payment token issuers. This clarity has accelerated investment in USD-pegged stablecoins, strengthening the digital dollar’s reach.

However, the report notes that the US framework does not prioritize cross-border fungibility. Instead, it focuses on reinforcing the dollar’s dominance by leveraging private-sector issuers, a strategy that encourages innovation but leaves questions about interoperability with foreign markets.

EU’s MiCA Regime Creates a More Restrictive Environment

Across the Atlantic, the EU’s Markets in Crypto-Assets (MiCA) regulation, already in force, takes a notably different approach. MiCA requires stablecoin issuers to hold a majority of reserves in EU-based banks, reflecting a preference for sovereign oversight and banking-sector control.

While supporters argue this enhances stability, critics warn it may create vulnerabilities of its own. Industry observers have cautioned that concentrating reserves within the EU banking system could introduce systemic risks and accelerate issuer consolidation, potentially limiting competition.

Regulatory Divergence Fractures Global Stablecoin Liquidity

CertiK warns that these opposing frameworks are splitting the global stablecoin landscape into two distinct ecosystems. In practice, this means USD-based and EUR-based stablecoins may operate under regulatory silos, reducing cross-border liquidity and making international transfers less efficient. The fragmentation could impair market depth, widen spreads, and delay the development of unified institutional settlement networks.

Monetary Priorities Drive the Divide

The report notes a fundamental difference in policy objectives:

• The US is using private innovation to expand the global influence of the dollar through regulated stablecoins.
• The EU, meanwhile, is prioritizing monetary sovereignty as it develops the digital euro alongside MiCA, ensuring that euro-denominated digital money remains tightly controlled and bank-intermediated.

These competing priorities shape how each region views the role of stablecoins in its broader financial system.

Consequences for Issuers and Global Crypto Markets

The regulatory split is already influencing where stablecoin companies choose to base operations, raise capital, and build infrastructure. Some firms see MiCA’s strict rules as prohibitive, while others view the GENIUS Act as a more supportive framework for innovation.

CertiK concludes that the divergence is not merely regulatory; it represents two fundamentally different visions for the future of digital money. As each ecosystem matures, global stablecoin markets may become increasingly bifurcated, with long-term implications for liquidity, adoption, and international financial integration.
