MiCA 2.0 Review Puts Stablecoins at Center of Europe’s Crypto Regulation Debate

Europe is preparing to review its landmark Markets in Crypto-Assets (MiCA) regulation, with stablecoins emerging as one of the biggest priorities as policymakers consider what many are calling "MiCA 2.0." Since MiCA was first proposed six years ago and officially enacted three years later, the digital asset market has evolved rapidly, particularly as businesses and consumers increasingly adopt stablecoins for cross-border payments and global transactions.

Unlike the original framework, which largely focused on spot cryptocurrency markets, the updated review is expected to address the growing role of fiat-backed stablecoins in Europe's financial system. The European Central Bank (ECB) has repeatedly warned that the dominance of U.S. dollar-backed stablecoins could weaken its influence over monetary policy across the eurozone. While the ECB continues to favor a central bank digital currency (CBDC) over privately issued euro stablecoins, industry experts believe attitudes toward regulated stablecoins have become more flexible.

John Orchard, chairman of the Digital Monetary Institute at OMFIF, said ECB officials have gradually softened their stance, particularly regarding stablecoins held on bank balance sheets or used for remittances. However, European policymakers remain reluctant to allow stablecoins to play a major role in wholesale financial settlements, unlike the United States, which has shown greater willingness to experiment with the technology.

The contrast between Europe and the U.S. has become more pronounced following the passage of the GENIUS Act, which established a regulatory framework for payment stablecoins under the oversight of the Federal Reserve and the Office of the Comptroller of the Currency. Dollar-backed stablecoins currently dominate the global market, accounting for approximately $310 billion of the $311 billion total stablecoin supply, according to DeFiLlama, leaving non-dollar alternatives with only a tiny share.

Another major issue under discussion is whether stablecoin issuers should be allowed to distribute yield to holders. Banking groups in both Europe and the United States have opposed interest-bearing stablecoins, arguing they could encourage consumers to move deposits from traditional banks into blockchain-based wallets, increasing the risk of deposit flight. Although the European Commission is reviewing the issue, significant changes appear unlikely.

Reserve management also remains a key distinction between the two regulatory systems. Under MiCA, stablecoin reserves are generally expected to flow back into the banking system, while the U.S. framework allows issuers to hold reserves in government securities such as Treasury bills. European policymakers are now considering whether MiCA should evolve toward a model similar to the GENIUS Act, allowing issuers to invest reserves in European money market instruments instead of routing funds back through banks.

One initiative attracting attention is Qivalis, a consortium of European banks and financial institutions working to develop a euro-denominated stablecoin. Because the participants are licensed banks, they can satisfy reserve requirements internally while supporting the European Union's broader objective of strengthening financial independence and reducing reliance on the U.S. dollar.

Europe also faces structural challenges that differ from the United States, including the absence of a unified Treasury bond market. Experts have suggested creating a synthetic European safe asset by allowing stablecoin reserves to invest in money market instruments issued by European governments, providing a potential alternative to the U.S. Treasury-backed model.

Another topic under review is the treatment of multi-issuance stablecoins such as Circle's USDC, which is issued by multiple legal entities across jurisdictions while remaining a single fungible digital asset for users. Catarina Veloso, director of regulatory and compliance at Notabene, noted that MiCA originally intended to support such models, but implementation sparked concerns among regulators, including the ECB, over associated risks.

Veloso argued that stablecoins derive much of their value from operating seamlessly across borders. Fragmenting globally recognized tokens into region-specific versions could reduce their usefulness and undermine one of their primary advantages in international payments.

Beyond stablecoins, European regulators are also considering whether greater supervisory authority should be transferred to the European Securities and Markets Authority (ESMA). Centralized oversight could improve consistency across member states, though critics warn it may create additional bureaucracy and slow innovation. Industry participants, including crypto trading firm B2C2, stress that any MiCA reforms should preserve Europe's ability to attract digital asset businesses while enabling companies to scale across international markets.

As Europe refines its crypto regulatory framework, the MiCA 2.0 review will likely shape the future of stablecoins, digital payments, and blockchain innovation across the region while determining how competitive the European crypto industry remains in an increasingly global market.
